The Indianapolis 500, commonly called the Indy 500, is held at the Indianapolis Motor Speedway, a {{convert|2.5|mi|2|adj=mid}} paved oval. First held in 1911, it is currently a points-paying race of the NTT IndyCar Series. The event is contested by "Indy cars", a formula of professional-level, single-seat, open cockpit, open-wheel, purpose-built race cars. The race is the most prestigious event of the IndyCar calendar, and one of the oldest and most important automobile races in the world.{{cite web |last=Indianapolis Motor Speedway |date=August 3, 2018 |title=USA Today Readers Name Indianapolis 500 As World's Best Motorsports Race In Poll |url=https://www.indianapolismotorspeedway.com/news-multimedia/news/2018/08/03/usa-today-readers-name-indy-500-worlds-best-motorsports-race-2018 |url-status= |website=IndianapolisMotorSpeedway}} The race traditionally has a field of 33 cars.

• IndyCar Series officials clarified the procedure for utilizing replacement drivers on race day. This is largely in response to the situation involving Kyle Larson at Arrow McLaren, who is scheduled to attempt Double Duty for the second time. If a team declares a replacement driver, that driver must pass a refresher test in the same entry, with minimal setup changes allowed. If the replacement driver is used on race day, the car will be moved to the rear of the starting grid (33rd).{{cite news|url=https://racer.com/2025/04/17/indycar-clarifies-replacement-indy-500-driver-guidelines/|title=IndyCar clarifies Indy 500 replacement driver guidelines|publisher=Racer|first=Marshall|last=Pruett|date=April 17, 2025|access-date=April 17, 2025|archive-date=April 17, 2025|archive-url=https://web.archive.org/web/20250417194816/https://racer.com/2025/04/17/indycar-clarifies-replacement-indy-500-driver-guidelines/|url-status=live}} The only driver to take part in the refresher course was 2013 Indianapolis 500 champion Tony Kannan.
• Each entry will be permitted 32 sets of tires for the entirety of the event, plus 8 additional sets for use during the Open Test.{{cite news|title=2025 NTT IndyCar Series Official Rulebook|url=https://epaddock.indycar.com/docs/default-source/rules-regulations-and-policies/indycar-rulebook.pdf|quote=Section 15.2.1|publisher=IndyCar.com|access-date=April 17, 2025|archive-date=April 14, 2025|archive-url=https://web.archive.org/web/20250414003655/https://epaddock.indycar.com/docs/default-source/rules-regulations-and-policies/indycar-rulebook.pdf|url-status=live}}

The Rookie Orientation Program at Indianapolis consists of three phases. For phase 1, each driver is required to complete ten laps between {{convert|205|–|210|mph|km/h|abbr=on}}, while demonstrating satisfactory car control, proper racing line, and safe interaction with other cars on the circuit. The laps do not have to be consecutive. Phase 2 is fifteen laps between {{convert|210|–|215|mph|km/h|abbr=on}}, and phase 3 is fifteen laps over {{convert|215|mph|km/h|abbr=on}}. Veteran drivers that have not competed in an IndyCar oval race since the previous year's Indy 500 are required to take a refresher test. The refresher test consists of phase 2 and phase 3 of the aforementioned rookie test.{{cite news|title=Larson to turn first IndyCar Series laps Thursday at IMS|url=https://www.indycar.com/news/2023/10/10-09-rop-hybrid-test-preview|publisher=IndyCar.com|date=October 9, 2023|access-date=October 12, 2023|archive-date=October 14, 2023|archive-url=https://web.archive.org/web/20231014053307/https://www.indycar.com/News/2023/10/10-09-ROP-Hybrid-Test-Preview|url-status=live}}

Siegel passed the three-phase test without incident.

A two-day offseason test was held on October 10–11, 2024. Eleven teams were in attendance to evaluate the hybrid energy recovery system powertrains which were adopted midway through the 2024 IndyCar season. On Thursday, Josef Newgarden (Team Penske), Pato O'Ward (Arrow McLaren), and Álex Palou (Ganassi) primarily conducted tire tests for Firestone. On Friday, all eleven teams participated.

• Summary: The veterans session of the open test began at 12:45 p.m. after problems with internet connectivity around the track were solved. Two drivers - Jack Harvey and Santino Ferrucci - suffered mechanical problems and each brought out caution periods as they stopped on track. At 2 p.m., the veteran session ended and the track was opened for drivers needing rookie and refresher tests. Rookies Louis Foster, Jacob Abel, and Robert Shwartzman all completed their rookie tests, while Kyle Larson, Takuma Sato, Marco Andretti, Devlin DeFrancesco, and Callum Ilott all successfully completed their refresher tests. At 4 p.m., the track was open to all entries. One notable incident occurred during the session with 13 minutes remaining when Graham Rahal drifted wide in turn 3 and brushed the outside wall. The impact damaged Rahal's suspension and Rahal slowed significantly to avoid spinning. A caution was put out as many cars slowed behind Rahal to avoid the potential spin.

• Summary:The first day of qualifying was scheduled from 11:00 a.m. to 5:50 p.m. Cars qualifying 1st–12th advanced to the Top 12 Qualifying session on Sunday. Cars qualifying in positions 13th–30th were locked-in to those positions. Cars qualifying 31st–34th moved on to take part in the Last Chance Qualifying session on Sunday to determine the final row of the starting grid. All entered cars were eligible for one guaranteed attempt on Saturday, then unlimited additional attempts were permitted, time-permitting, until 5:50 p.m.

:One major accident occurred at 12:05 p.m. during the guaranteed runs, when Colton Herta spun in turn 1 on the first lap of his attempt and heavily impacted the outside wall. Herta's car then became airborne, flipped and landed upside down before sliding against the turn 2 wall and coming to a stop.{{cite web|url=https://racer.com/2025/05/17/herta-fourth-to-hammer-indy-walls-in-24-hours|title=Herta fourth to hammer Indy walls in 24 hours|first=Marshall|last=Pruett|date=May 17, 2025|accessdate=May 17, 2025|website=racer.com|publisher=Racer Media & Marketing, Inc.|archive-date=May 19, 2025|archive-url=https://web.archive.org/web/20250519225122/https://racer.com/2025/05/17/herta-fourth-to-hammer-indy-walls-in-24-hours|url-status=live}} Herta's Andretti Global team switched to a backup car after the accident, and Herta would qualify later in the day in the 29th position.

:With only the top 30 cars locked in during Saturday qualifying, the slowest four qualifiers would need to qualify again on Sunday in the Last Chance Qualifying session. The fight for the 30th and final locked-in position for much of the day was between Graham Rahal and Marco Andretti. Rahal narrowly avoided being in the Last Chance Qualifying for a third-straight year, besting Andretti by only 0.0028 seconds. Andretti was thereby relegated to Last Chance Qualifying on Sunday. Dale Coyne Racing teammates Rinus VeeKay and Jacob Abel also posted times too slow to make the top 30 and were also relegated to the Last Chance Qualifier. Marcus Armstrong, driving a backup car after his crash in morning practice, made two qualifying attempts late in the day, but aborted both runs and posted no time on Saturday.{{cite web|url=https://www.motorsport.com/indycar/news/Marco-Andretti-kicked-to-LCQ-Alex-Palou-fastest-in-Indy-500-Saturday-qualifying/10723733/|title=Marco Andretti kicked to LCQ, Alex Palou fastest in Indy 500 Saturday qualifying|first=Nick|last=DeGroot|date=May 17, 2025|accessdate=May 17, 2025|website=motorsport.com|publisher=Motorsport Network, LLC.|archive-date=May 18, 2025|archive-url=https://web.archive.org/web/20250518000940/https://www.motorsport.com/indycar/news/Marco-Andretti-kicked-to-LCQ-Alex-Palou-fastest-in-Indy-500-Saturday-qualifying/10723733/|url-status=live}}

• Summary: A pre-qualifying practice was held from 1:00 p.m. to 3:00 p.m. The first hour of practice was open to cars participating in the Fast 12 qualifying, while the second hour was open to cars in the Last Chance Qualifying. At 1:18 p.m., Scott McLaughlin, on the fourth and final lap of a simulated qualifying run, spun exiting turn 2 and heavily impacted the wall. The car became airborne and initially landed on its side, severing the left-rear wheel from the car and creating a gouge in the track surface before it came back down upright. McLaughlin was uninjured, but the car was damaged beyond repair.

• Summary: Top 12 qualifying began at 4:05 p.m., with each entry permitted one attempt. Positions 1–6 in this session advanced to the Fast Six qualifying session, while positions 7–12 were locked in to their spots. Prior to the start of the session, both remaining Team Penske cars of Josef Newgarden and Will Power failed pre-qualifying technical inspection and were thereby not allowed to compete in the session. Team president Tim Cindric explained afterwards that the issue was over filling seams in the cars' rear-crash structures to improve airflow, which was a violation of INDYCAR rules. Since they did not make an attempt during the Top 12 session, the three Penske cars were lined up behind all other Top 12 qualifiers in the order of their Saturday qualification times. Scott McLaughlin was assigned 10th starting position, Newgarden 11th, and Power 12th. IndyCar indicated that further potential penalties for the technical violations would be possible pending investigation.{{cite web|url=https://racer.com/2025/05/18/cindric-explains-penske-indy-qualifying-infractions|title=Cindric explains Penske Indy qualifying infractions|first=Marshall|last=Pruett|date=May 18, 2025|accessdate=May 18, 2025|website=racer.com|publisher=Racer Media & Marketing, Inc.|archive-date=May 18, 2025|archive-url=https://web.archive.org/web/20250518215005/https://racer.com/2025/05/18/cindric-explains-penske-indy-qualifying-infractions|url-status=live}}

• Summary: Last Chance Qualifying began at 5:15 p.m. and lasted one hour. The session determined positions 31–33 on the starting grid, as well as the one entry failing to qualify. All entries were given one guaranteed attempt. Unlimited subsequent attempts were permitted, but would require that their existing times be withdrawn and erased. After the guaranteed runs, Marco Andretti was comfortably in 31st position, with Marcus Armstrong fairly close behind in 32nd. Rinus VeeKay sat in the 33rd and final position, with Jacob Abel not in the field as 34th fastest. With under 8 minutes remaining, VeeKay's crew withdrew his time in order to make another attempt. However, he ran slower on his second attempt at {{convert|226.913|mph|kph}} and fell within potential reach of Abel. Just before time expired, Abel took to the track for one last attempt. However, Abel was unable to bump his way into the field, only running at {{convert|226.394|mph|kph}}. VeeKay held on to 33rd position, and Abel failed to qualify.{{cite web|url=https://www.motorsport.com/indycar/news/jacob-abel-indy-500-qualifying-fails-to-make-race-teammate-veekay/10724250/|title=Jacob Abel fails to qualify for Indy 500 in teammate battle over last spot|first=Nick|last=DeGroot|date=May 18, 2025|accessdate=May 18, 2025|website=motorsport.com|publisher=Motorsport Network, LLC.|archive-date=May 19, 2025|archive-url=https://web.archive.org/web/20250519003716/https://www.motorsport.com/indycar/news/jacob-abel-indy-500-qualifying-fails-to-make-race-teammate-veekay/10724250/|url-status=live}}

• Summary: Fast Six qualifying began at 6:25 p.m., which all drivers given one attempt to qualify. This session determined the first six starting spots on the starting grid. Rookie Robert Shwartzman qualified on pole position with a four-lap average at {{convert|232.790|mph|kph}}, the Russo-Israeli deposing two-time winner Takuma Sato with the fourth run of the session. The result was considered surprising, as neither Shwartzman nor the Prema Racing team he drove for had prior oval racing experience prior to this event. Shwartzman was the first race rookie to qualify on pole since Teo Fabi in 1983,{{efn|name=Stewart1996}} whilst the Prema team additionally became the first rookie team to qualify on pole position at the Indianapolis 500 since Teddy Mayer's Mayer Motor Racing team in 1984. Sato qualified in 2nd place, while Pato O'Ward completed the front row.

An overnight investigation was held in to the technical infractions committed by Team Penske's cars prior to the Fast 12. On May 19, Indycar announced that both Josef Newgarden and Will Power would be moved to the rear of the grid and start from 32nd and 33rd, respectively. For both entries, the team strategists were suspended for the remainder of the event, the teams were fined $100,000 each, and the entries were stripped of all points for qualifying in the top 12. The third Penske car of Scott McLaughlin was found not to be in violation of rules and thereby maintained its starting position.{{cite web|url=https://www.indycar.com/news/2025/05/05-19-penske-penalties|title=INDYCAR Update on Team Penske Technical Violations|date=May 19, 2025|accessdate=May 19, 2025|website=indycar.com|publisher=Brickyard Trademarks, LLC.|archive-date=May 19, 2025|archive-url=https://web.archive.org/web/20250519151014/https://www.indycar.com/news/2025/05/05-19-penske-penalties|url-status=live}} Some consideration was given to elevating Jacob Abel in to the starting grid and pushing one of the Penske cars out, but this was dismissed.

• Summary: Carb Day was the final practice day before the race. A two hour session was scheduled from 11:00 a.m. until 1:00 p.m. While no incidents occurred during the session, several drivers suffered mechanical failures that necessitated caution periods. At 11:38 a.m., Graham Rahal suffered an engine problem and came to a halt on the backstraight. At 12:18, Ryan Hunter-Reay suffered a major fire in his car and came to a stop at the entrance to the pit lane. The fire caused significant damage to Hunter-Reay's car, forcing his team to switch to a backup car.{{cite web|url=https://racer.com/2025/05/23/hunter-reay-forced-into-backup-car-after-carb-day-fire|title=Hunter-Reay forced into backup car after Carb Day fire|first=Marshall|last=Pruett|date=May 23, 2025|accessdate=May 23, 2025|website=racer.com|publisher=Racer Media & Marketing, Inc.}} At 12:45 p.m., Takuma Sato suffered an engine problem and came to halt on his backstraight.

As part of Carb Day festivities, a race between all six existing Oscar Mayer Wienermobiles was announced, with each Wienermobile representing a different regional dog. The race, titled the "Wienie 500",{{cite web|url=https://news.kraftheinzcompany.com/press-releases-details/2025/Oscar-Mayers-Fleet-of-Wienermobiles-Go-Head-to-Head-in-Inaugural-Wienie-500--First-Ever-High-Stakes-Race-on-the-Iconic-Indianapolis-Motor-Speedway/default.aspx|title=Oscar Mayer's Fleet of Wienermobiles Go Head-to-Head in Inaugural "Wienie 500" – First Ever, High-Stakes Race on the Iconic Indianapolis Motor Speedway|date=May 20, 2025|accessdate=May 23, 2025|website=kraftheinzcompany.com|publisher=Kraft Heinz}} was claimed to be the first gathering of all Wienermobiles in over a decade. The 5-mile race consisted of two laps around the track from a standing start.

The #02 New York Dog grabbed the lead at the start, and led the field into turn one. Down the backstretch, the #01 Chicago Dog made a pass for the lead, with the #04 Sonoran Dog slipping into second. Chicago Dog led the first lap, with Sonoran Dog close behind in second, and the #08 Slaw Dog third. Just after the start/finish line, Sonoran Dog took over the lead, and led through turn one. Coming out of turn two, Sonoran Dog's engine started smoking, possibly overheating, which handed the lead back to Chicago Dog. As the field came down the frontstrech for the checkered flag, Slaw Dog made a slingshot pass to take the victory by less than one length.{{cite web|url=https://www.indystar.com/story/entertainment/indy-500/2025/05/23/2025-indy-500-carb-day-which-wienermobile-won-wienie-500-indianapolis-motor-speedway-slaw-dog/83812725007/|title=Put some mustard on that slaw dog.

The 46th annual Pit Stop Challenge was scheduled for Friday May 23, after the completion of Carb Day practice. For 2025, the event picked up sponsorship from Oscar Mayer and was officially the "Oscar Mayer $150,000 Pit Stop Challenge" for sponsorship reasons. The bracket for the competition was announced on May 21. Fourteen teams participated in the competition, with two teams – the #5 Arrow McLaren car and the #9 Chip Ganassi Racing car – receiving first-round byes.{{cite web|url=https://www.indycar.com/news/2025/05/05-21-pitstop-preview|title=Crews To Enter Spotlight in Oscar Mayer $150,000 Pit Stop Challenge|accessdate=May 21, 2025|date=May 21, 2025|website=indycar.com|publisher=Brickyard Trademarks, LLC}} Team Penske won the competition with Josef Newgarden's crew, defeating fellow Team Penske driver Will Power's crew in a best-of-three final. It was the 20th win for Team Penske in the event and the third for Newgarden, who successfully defended his 2024 victory.

Weather {{convert|63|°F|0}}, Cloudy with brief periods of light rain in the early afternoon.

The race was scheduled to begin at 12:45 p.m. on May 25, but was delayed by roughly 30 minutes due to light rain.{{cite web|url=https://www.motorsport.com/indycar/news/indianapolis-500-start-delayed-due-to-light-rain-showers/10726642/|title=Indianapolis 500 start delayed due to light rain showers|first=Nick|last=DeGroot|date=May 25, 2025|accessdate=May 25, 2025|website=motorsport.com|publisher=Motorsport Network, LLC}}

File:Indy5002025start.webm's crash in turn 1.]]

During the parade laps, Scott McLaughlin lost control of his car while attempting to warmup his tires, causing him to crash into the pit wall on the front straight, spin, and come to a rest in turn 1. McLaughlin's race was over before the green flag.{{cite web|url=https://racer.com/2025/05/25/mclaughlin-andretti-first-out-at-indy|title=McLaughlin, Andretti first out at Indy|first=Marshall|last=Pruett|date=May 25, 2025|accessdate=May 25, 2025|website=racer.com|publisher=Racer Media & Marketing, Inc.}} Scott Dixon also began to suffer problems during the parade laps, with a fire appearing from the brakes on the left-rear of the car. After McLaughlin's wreck, laps began counting toward the race distance and the race officially began under yellow. The field still lined up for the traditional 3-wide start for the first green flag, officially on lap 4. Polesitter Robert Shwartzman moved into the lead ahead of Pato O'Ward, but further back in the field, Marco Andretti made contact with Jack Harvey, causing Andretti to lose control and impact the outside wall in turn 1.

Racing resumed at lap 8 with Pato O'Ward briefly taking the lead, before being passed by Takuma Sato. Sato remained in the lead until the third caution period came on lap 19, when rain began to fall on the track. During the caution, the majority of the field chose to make pit stops, though some cars, including all ECR cars as well as Rinus VeeKay, chose not to stop and moved to the front of the field. Racing resumed once the rain subsided by lap 29, with Alexander Rossi leading ECR teammate Christian Rasmussen. Rossi and Rasmussen exchanged the lead several times until their pit stops.{{cite web|url=https://www.cbssports.com/general/news/2025-indianapolis-500-results-alex-palou-holds-off-marcus-ericsson-to-win-his-first-indy-500/live/|title=2025 Indianapolis 500 results: Alex Palou holds off Marcus Ericsson to win his first Indy 500|first=Steve|last=Taranto|date=May 25, 2025|accessdate=May 26, 2025|work=CBS Sports}} Once cars that stayed out pitted, Sato retook the lead and remained in the lead through the next cycle of stops, while those on the alternate strategy moved up the order. Rossi, the leading car on the alternate strategy, began to develop problems with an overheating gearbox in the second quarter of the race and the car began trailing smoke. On lap 74, Rossi was forced to pit for repairs. As Rossi shut the car off in his pit stall, the car erupted into flames while several crew members were working on it. Neither Rossi nor any crew members were injured in the fire, but it was the end of the race for his team.{{cite web|url=https://www.motorsport.com/indycar/news/Watch-Alexander-Rossis-day-goes-up-in-flames-at-the-Indianapolis-500/10726755/|title=Watch: Alexander Rossi's day goes up in flames at the Indianapolis 500|first=Aaron|last=Bearden|date=May 25, 2025|accessdate=May 26, 2025|website=motorsport.com|publisher=Motorsport Network, LLC.}}

On lap 82, the fourth caution period of the race came, as Rinus VeeKay lost control of his car attempting to enter the pit lane, spun, and hit the inside pit lane wall. VeeKay later indicated that the car had experienced brake failure, which had contributed to him losing control.{{cite web|url=https://racer.com/2025/05/25/veekay-runs-up-to-sixth-before-pitlane-crash-ends-day-early|title=VeeKay runs up to sixth before pitlane crash ends day early|first=Marshall|last=Pruett|date=May 25, 2025|accessdate=May 26, 2025|website=racer.com|publisher=Racer Media & Marketing, Inc.}} The subsequent pit stops under the caution created a major shake up in the running order. Takuma Sato, who had led the majority of the race to this point, slid too far forward in his pit box, forcing the crew to drag the car back before starting work. This mistake dropped Sato out of the top 10 positions, and he would not lead the race again.{{cite web|url=https://rahal.com/sato-led-51-of-first-86-laps-in-the-indy-500-but-a-pit-error-led-him-to-finish-11th-defrancesco-led-17-laps-foster-rahal-15-20/|title=Sato Led 51 of First 86 Laps in the Indy 500 But a Pit Error Led Him to Finish 11th; DeFrancesco Led 17 Laps & Finished 14th; Foster & Rahal 15 & 20|accessdate=May 26, 2025|website=rahal.com|publisher=Rahal Letterman Lanigan Racing}} Additionally, polesitter Robert Shwartzman suffered brake failure on his car entering his pit stall, causing him to slide in to his pit wall and collide with three of his pit crew members. One of the crew members suffered an injured foot in the collision. Shwartzman's impact with the pit wall damaged the car, and he was forced to retire from the race.{{cite web|url=https://racer.com/2025/05/25/shwartzman-s-indy-500-hopes-dashed-with-pit-crash-credited-p29|title=Shwartzman's Indy 500 hopes dashed, credited P29 after pitlane crash|first=Marshall|last=Pruett|date=May 26, 2025|accessdate=May 26, 2025|website=racer.com|publisher=Racer Media & Marketing, Inc.}} Álex Palou emerged first from those that pitted, with David Malukas behind. Ryan Hunter-Reay moved in to the lead of the race, with Devlin DeFrancesco, Jack Harvey, and Marcus Ericsson close behind on an alternate strategy from the main leaders.

Racing resumed at lap 92, but nearly immediately the caution was out again as Kyle Larson lost control of his car in turn 2 and spun. As he spun, Larson collected the cars of Kyffin Simpson and Sting Ray Robb, sending both of them into spins as well and into the wall. All three drivers retired from the race in the incident.{{cite web|url=https://www.motorsport.com/indycar/news/kyle-larson-wrecks-out-of-the-indy-500-in-restart-melee/10726767/|title=Dejected Kyle Larson wrecks out of the Indy 500 in restart melee|first=Nick|last=DeGroot|date=May 25, 2025|accessdate=May 26, 2025|website=motorsport.com|publisher=Motorsport Network, LLC}} Larson, after doing a routine medical checkup after the accident, immediately left the track to travel to Charlotte to compete in that night's Coca-Cola 600.

Hunter-Reay pitted on lap 103, handing the lead to DeFrancesco. An attempted restart was made at lap 106, but as the green flag was shown, Christian Rasmussen made light contact with the wall in the north short chute, sending him into a half spin. Rasmussen was able to save the car with no major damage, but the incident did bring the caution back out for the sixth time in the race. Racing resumed again at lap 109. DeFrancesco maintained the lead, while further back in the field, Conor Daly passed both Palou and Malukas to move to the head of those on the primary strategy. After DeFrancesco pitted on lap 120, Daly moved into the lead of the race. Josef Newgarden, who had started at the rear of the field, also began to appear near the top at this point, running seventh at the 300 mile mark. However, Newgarden's race came to an abrupt end shortly after, when the fuel pump on his car failed after 135 laps, thwarting his attempt to win three "500"s in a row.{{cite web|url=https://racer.com/2025/05/25/fuel-pump-ends-newgarden-s-quest-for-three-in-a-row|title=Fuel pump ends Newgarden's quest for three-in-a-row|first=Marshall|last=Pruett|date=May 25, 2025|accessdate=May 26, 2025|website=racer.com|publisher=Racer Media & Markting, Inc.}} As those on the main strategy pitted around lap 140, Ryan Hunter-Reay returned to the lead of the race on the alternate strategy. Hunter-Reay maintained a large enough lead that after his next pit stop, he remained the leader and appeared to be in position to challenge for the win. Hunter-Reay's hopes ended on his final pit stop, as he ran out of fuel entering pit lane.{{cite web|url=https://www.indystar.com/story/sports/motor/indy-500/2025/05/25/2025-indy-500-finishing-order-alex-palou/83856839007/|title=One sentence on each driver from the 2025 Indy 500|first=Christopher|last=DeHarde|date=May 25, 2025|accessdate=May 26, 2025|website=indystar.com|publisher=The Indianapolis Star}} With the fuel lines dry, the car would not refire, and Hunter-Reay was forced to retire from the race. At the same time, Conor Daly began to suffer handling problems from a vibration and quickly lost several positions before making a pit stop.

As those on the main strategy made their final pit stops, David Malukas emerged ahead of Álex Palou, while several on the alternate strategy had yet to pit. Palou then moved ahead of Malukas to become the effective leader on the main strategy. However, once those on the alternate strategy pitted, Marcus Ericsson emerged as the leader of the race, having needed to take less fuel than those on the main strategy. Ericsson was just ahead of Palou and Malukas, but immediately ahead of the leaders were Louis Foster and Devlin DeFrancesco, who were battling to avoid being lapped. The turbulent air generated by these two cars made it difficult for the leaders to pass, helping Ericsson stay in the lead. However, on lap 187, Palou dove to the inside of Ericsson and took the lead in turn 1. The continued presence of the two nearly-lapped cars allowed Palou to maintain the lead for the remainder of the race. Ericsson attempted one final run at Palou through turns 3 and 4 of the last lap, but the seventh and final caution came out as the leaders rounded the final turn as Nolan Siegel lost control of his car and crashed in turn 2. The race officially ended under yellow with Palou as the winner. Ericsson came across the line in second, while Malukas finished third. Pato O'Ward and Felix Rosenqvist rounded out the top five.{{cite web|url=https://racer.com/2025/05/25/palou-ticks-the-last-boxes-with-indy-500-triumph|title=Palou ticks the last boxes with Indy 500 triumph|first=Mark|last=Glendenning|date=May 25, 2025|accessdate=May 26, 2025|website=racer.com|publisher=Racer Media & Marketing, Inc.}}

Palou became the first Spaniard to take victory in the Indianapolis 500. For his team, Chip Ganassi Racing, it was their sixth victory in the race. Palou's victory also continued a dominant season, as he had now won five out of the six races run to this point for the 2025 Indycar season. For winning, Palou earned $3.8 million from a record purse of $20,283,000. Polesitter Robert Shwartzman was named Rookie of the Year despite his pit lane crash before halfway through the race.{{cite web|url=https://racer.com/2025/05/26/indy-500-confirms-fourth-straight-record-purse|title=Indy 500 confirms fourth straight record purse|date=May 26, 2025|accessdate=May 26, 2025|website=racer.com|publisher=Racer Media & Marketing, Inc.}}

On May 26, the day after the race, IndyCar announced that Marcus Ericsson, Kyle Kirkwood, and Callum Ilott's cars had all failed post-race technical inspection and were stripped of their finishing positions. For Ericsson and Kirkwood – teammates at Andretti Global – it was discovered that modifications had been made to the Dallara-supplied Energy Management System (EMS) covers and cover-to-A-arm mounting points with unapproved spacers and parts. Indycar rules stipulated that those parts must be used as supplied and series officials indicated the unapproved parts may have provided an aerodynamic advantage. For Ilott's Prema Racing car, it was found that the front wing failed to meet rules for minimum endplate height and location. All three entries were moved to the rear of the finishing field, fined $100,000 each, and had their respective team managers suspended for the following race at Detroit.{{cite web|url=https://racer.com/2025/05/26/andretti-prema-penalized-after-indy-500|title=Andretti, PREMA penalized for Indy 500 tech violations|first=Marshall|last=Pruett|date=May 26, 2025|accessdate=May 26, 2025|website=racer.com|publisher=Racer Media & Marketing, Inc.}}

The post-race penalties elevated David Malukas to second place, Pato O'Ward to third, Felix Rosenqvist to fourth, and Santino Ferrucci to fifth.

In the wake of the numerous technical violations found throughout the month, the IndyCar series began the process of major overhauls to its officiating system. IndyCar first announced that they would work toward the creation of an officiating body independent of the series or Penske Entertainment and with no Penske employees.{{cite web|url=https://racer.com/2025/05/21/indycar-evolving-toward-officiating-revolution|title=IndyCar evolving toward officiating revolution|first=Marshall|last=Pruett|date=May 21, 2025|accessdate=May 30, 2025|website=racer.com|publisher=Racer Media & Marketing, Inc.}} IndyCar had served as its own officiating body since dismissing USAC midway through the 1996–97 season. Conflict of interest concerns were raised by team owners and media members after Roger Penske purchased the series in 2020 while still fielding a team, which came to a head after Team Penske's attenuator violations during qualifying, marking the second season in a row that Penske's team had been found with major rules violations. Some rumors were reported that Honda threatened to end their involvement with IndyCar if the series did not move toward independent officiating due to the Penske technical violations, though Penske Entertainment and the Indycar series declined to comment on the topic. The series announced a week after the race that they were targeting to have the new officiating body ready for the 2026 season.{{cite web|url=https://racer.com/2025/05/31/indycar-commits-to-independent-officiating-board-for-2026|title=IndyCar commits to independent officiating board for 2026|first=Marshall|last=Pruett|date=May 31, 2025|accessdate=May 31, 2025|website=racer.com|publisher=Racer Media & Marketing, inc.}}

Further updates to IndyCar's officating process were discussed after the race. The series announced that they were working towards implementing a scanning process during pre-race and post-race technical inspections to assist with catching technical violations. The announcement came after it was realized that Team Penske's attenuator violations had been missed during technical inspection for at least a full year, including at the 2024 Indianapolis 500. Four teams – Chip Ganassi Racing, A. J. Foyt Racing, Arrow McLaren, and Andretti Global – provided their Indianapolis 500 cars for IndyCar to do verification scans for baseline data for the scanning system.

The race was televised live by Fox for the first time, as the network took over from NBC, who had been the television broadcaster since 2019.

Fox's coverage faced criticism from viewers for multiple aspects of its production, including a large number of commercial breaks, which, in some cases, caused the coverage to miss notable moments of the race, and cutting away from Palou crossing the finish line to cover Nolan Siegel's final lap crash, which had no bearing on the outcome.{{Cite web |last=Frank |first=Evan |title='Come on man': Indianapolis 500 viewers aren't happy with the amount of commercials on Fox |url=https://www.indystar.com/story/sports/motor/indy-500/2025/05/25/indy-500-commercials-fox-broadcast-fans-reaction-unhappy/83855496007/ |access-date=2025-05-26 |website=The Indianapolis Star |language=en-US}}{{Cite web |last=Frank |first=Evan |title=Crashes at the 2025 Indianapolis 500: Kyle Larson, Scott McLaughlin, Rinus VeeKay and more |url=https://www.indystar.com/story/sports/motor/indy-500/2025/05/25/indianapolis-500-crashes-kyle-larson-marco-andretti-rinus-veekay-scott-mclaughlin-robert-shwartzman/83854859007/ |access-date=2025-05-26 |website=The Indianapolis Star |language=en-US}}{{Cite web |last=Shipley |first=Reice |date=2025-05-25 |title=Viewers frustrated with number of commercials on Fox's Indy 500 broadcast |url=https://awfulannouncing.com/fox/viewers-complaints-commercial-indy-500-broadcast.html |access-date=2025-05-26 |website=Awful Announcing |language=en-US}}
