• Summary: The Last Chance Qualifying session was delayed by five minutes, opening at 4:05 p.m. and lasting until 5:05 p.m. The session determined positions 31–33 for the starting grid and which car would not qualify. Each car was given one guaranteed attempt, with subsequent attempts allowed but requiring the withdrawal of a previous attempt. After the guaranteed runs, Jack Harvey was the slowest of the drivers in the session. After the initial failure to reach the top 33, Harvey made two more attempts. Harvey's third attempt came as time expired during the session, during which Harvey qualified fast enough to bump his teammate Graham Rahal out of the field, meaning that Rahal would not start the race. Rahal's failure to qualify came thirty years after his father Bobby Rahal failed to qualify for the 1993 race.{{cite web|url=https://racer.com/2023/05/21/rahal-misses-indy-500-after-being-bumped-by-teammate-harvey/|title=Rahal misses Indy 500 after being bumped by teammate Harvey|first=David|last=Malsher-Lopez|date=May 21, 2023|accessdate=May 21, 2023|website=Racer.com|publisher=Racer Media & Marketing, Inc.|archive-date=May 21, 2023|archive-url=https://web.archive.org/web/20230521215039/https://racer.com/2023/05/21/rahal-misses-indy-500-after-being-bumped-by-teammate-harvey/|url-status=live}}

Prior to the race start, Graham Rahal suffered problems with the battery of his car. His crew was able to get the battery changed, but not before two laps of the race had already been completed.{{cite web|url=https://racer.com/2023/05/28/newgarden-rises-above-multiple-late-restarts-to-win-indy-500/|title=Newgarden rises above multiple late restarts to win Indy 500|first1=David|last1=Malsher-Lopez|first2=Mark|last2=Glendenning|date=May 28, 2023|accessdate=May 28, 2023|website=Racer.com|publisher=Racer Media & Marketing, Inc.|archive-date=May 28, 2023|archive-url=https://web.archive.org/web/20230528210641/https://racer.com/2023/05/28/newgarden-rises-above-multiple-late-restarts-to-win-indy-500/|url-status=live}}

At the start, Álex Palou took the lead of the race ahead of Rinus VeeKay and Felix Rosenqvist, while Scott Dixon moved into fourth. As the first run progressed, Palou and VeeKay swapped the lead with each other several times. Behind, Dixon began to suffer a vibration in one of his tires after 20 laps, which caused him to drop down to 16th position before finally making a pit stop to change the tires at lap 27. Shortly after, the first round of scheduled pit stops occurred, with the top two runners emerging in the same order, while Santino Ferrucci moved into third. During the pit sequence, Katherine Legge lost control of her car leaving her pit stall, spun, and hit the inside pit wall. Legge attempted to continue in the race for a few more laps, but was ultimately forced to retire after the incident.{{cite web|url=https://motorsports.nbcsports.com/2023/05/28/josef-newgarden-claims-first-indy-500-victory-marcus-ericsson-roger-penske/|title=Josef Newgarden claims first Indy 500 victory, outdueling Marcus Ericsson in 1-lap shootout|first=Nate|last=Ryan|date=May 28, 2023|accessdate=May 28, 2023|website=nbcsports.com|publisher=NBC Universal|archive-date=May 28, 2023|archive-url=https://web.archive.org/web/20230528203005/https://motorsports.nbcsports.com/2023/05/28/josef-newgarden-claims-first-indy-500-victory-marcus-ericsson-roger-penske/|url-status=live}} The second sequence of pit stops came beginning at lap 60, during which Arrow McLaren teammates Rosenqvist and Pato O'Ward moved into the lead of the race as the result of better fuel mileage than the cars ahead of them.

File:Sting ray robb crash (52959115715).jpg caused the first caution period of the race after an accident in Turn 1.]]

The first caution period of the day came at lap 91, when Sting Ray Robb slid wide and crashed into the outside wall of turn 1 after being passed by Graham Rahal. Robb was uninjured in the accident. During the caution, most drivers elected to make pit stops. During the stops, Rinus VeeKay lost control of his car exiting his pit stall and spun, collecting Álex Palou in the process. While both of the early leaders were able to continue in the race, Palou dropped deep in the field after being forced to change the front wing on his car from the damage, while VeeKay received a drive-through penalty for causing the incident. Neither driver led for the remainder of the race. Rosenqvist, O'Ward, and Ferrucci led drivers off of pit lane, while Callum Ilott took the lead of the race by being the only driver not to pit under the caution.

Racing resumed on lap 100, with Rosenqvist and O'Ward passing Ilott immediately to take the lead of the race again. Further behind, Marcus Ericsson and Josef Newgarden had excellent restarts, moving forward several spots to take fifth and sixth respectively. After a few laps, action calmed again and Rosenqvist and O'Ward resumed their swapping of the lead. With the previous pit stop coming with awkward timing for strategy, the pace of the race slowed greatly as teams tried to reach their target fuel window, with laps being turned at only {{convert|207|mph|km/h|abbr=on}} for several laps. Pits stops came again starting at lap 132. Rosenqvist emerged as the leader, but O'Ward suffered a slow stop that dropped him back. Newgarden and Ericsson emerged from the pits second and third, but both passed Rosenqvist shortly after, and Ericsson then passed Newgarden for the lead. Alexander Rossi moved to fourth place, while Santino Ferrucci ran fifth. During the pit stops, an incident occurred in the pit lane when Colton Herta left his stall while Romain Grosjean was entering his, causing the two to collide. Both continued in the race, though losing significant time.

The second caution period of the race came on lap 149, when Romain Grosjean lost control of his car in turn 2 and impacted the outside wall.{{cite web|url=https://www.nbcsports.com/video/romain-grosjean-out-lap-149-indy-500-indianapolis-motor-speedway|title=Grosjean wrecks on Lap 149 of Indy 500|date=May 28, 2023|accessdate=May 28, 2023|website=nbcsports.com|publisher=NBC Universal|archive-date=May 29, 2023|archive-url=https://web.archive.org/web/20230529033152/https://www.nbcsports.com/video/romain-grosjean-out-lap-149-indy-500-indianapolis-motor-speedway|url-status=live}} During the caution, some cars chose to pit, most notably Pato O'Ward, who had problems refueling his car on the previous pit stop and so required an extra stop compared to the cars around him. Racing resumed at lap 156, with Newgarden taking the lead from Ericsson before both were passed by Ferrucci one lap later. Rosenqvist and Rossi ran fifth and sixth, while Kyle Kirkwood moved himself to sixth and Álex Palou moved to seventh after recovering from his earlier incident. The running order remained roughly the same until the start of the final round of pit stops starting at lap 169. Ferrucci lost time after a tire rolled out from his pit box during his stop; he avoided any time penalty for the infraction. Ericsson emerged the leader of the group that pitted, with Rosenqvist and Newgarden behind. Leading the race were the drivers who had pitted during the caution, with O'Ward leading until lap 180, when he pitted. O'Ward emerged from the pits in third place, and quickly moved past both Rosenqvist and Ericsson to be first of the cars not needing any more pit stops.

On lap 184, Josef Newgarden passed Felix Rosenqvist entering turn 1. Rosenqvist slid wide in the wake of Newgarden's car and impacted the outside wall. Rosenqvist attempted to retain control of the car, but lost control entering turn two and spun. As he spun backwards onto the racing surface, Rosenqvist collected Kyle Kirkwood, which completely dislodged the left-rear tire on Kirkwood's car. Kirkwood impacted the outside wall in turn 2 heavily, with the impact causing the car to flip over and slide to a halt upside down. Neither Rosenqvist nor Kirkwood were injured in the accident. During the incident, the dislodged tire from Kirkwood's car was launched above the catch-fencing outside of turn 2 and out of the race track. The tire went over a grandstand and landed on the left front end of a Chevrolet Cruze that was parked in a lot between two sections of seating outside turn two. Robin Matthews, the owner of the damaged car, received a tour of the speedway as compensation.{{Cite web |date=May 28, 2023 |title=Indy 500 fan whose car was struck by errant tire invited to kiss the bricks |url=https://www.wthr.com/article/sports/motor/indianapolis-500/indy-500-fan-whose-car-was-struck-by-errant-tire-invited-to-kiss-the-bricks/531-6268d5eb-86e4-4872-aab5-2926812e8223 |access-date=2023-05-29 |website=wthr.com |language=en-US |archive-date=2023-05-29 |archive-url=https://web.archive.org/web/20230529062600/https://www.wthr.com/article/sports/motor/indianapolis-500/indy-500-fan-whose-car-was-struck-by-errant-tire-invited-to-kiss-the-bricks/531-6268d5eb-86e4-4872-aab5-2926812e8223 |url-status=live }}{{cite web|url=https://motorsports.nbcsports.com/2023/05/28/indy-500-tire-red-flags-fence-felix-rosenqvist-kyle-kirkwood/|title=Tire flies over Turn 2 catchfence in Indy 500 crash among three red flags in last 16 laps|first=Nate|last=Ryan|date=May 28, 2023|accessdate=May 28, 2023|website=nbcsports.com|publisher=NBC Universal|archive-date=May 28, 2023|archive-url=https://web.archive.org/web/20230528195456/https://motorsports.nbcsports.com/2023/05/28/indy-500-tire-red-flags-fence-felix-rosenqvist-kyle-kirkwood/|url-status=live}}{{Cite web |last=Nye |first=Nick |date=2023-05-29 |title=This is Robin Matthews of Indy.

With the circuit needing significant cleanup from the accident, IndyCar officials halted the race with the red flag with 14 laps to go. This was done to provide an opportunity to finish the race under green, and to not waste too many laps circulating under the yellow flag. Ryan Hunter-Reay held the lead at the time of the red flag, but he along with Callum Ilott and Agustín Canapino would need to pit as soon as the race resumed.

File:2023Indy500oward (cropped).jpg

The race resumed under caution on lap 187. The three cars at the front needing a pit stop did so immediately, handing the lead to Pato O'Ward. The field was preparing to go back to green with 9 laps to go. However, the officials deemed that O'Ward was taking the field down too slowly, and waved off the restart by an extra lap.

Green flag racing resumed on lap 193 (8 laps to go), with Newgarden and Ericsson passing O'Ward heading into turn one. O'Ward attempted to pass Ericsson back at turn three, but lost control of his car, spun several times and impacted the outside wall. O'Ward's accident caused a chain of accidents behind. Scott McLaughlin collided with Simon Pagenaud as the field slowed to avoid O'Ward, which sent Pagenaud into the outside wall while McLaughlin suffered damage to the nose of his car. Agustín Canapino was forced into the grass trying to avoid McLaughlin, causing him to lose control of his car and also hit the wall. After the initial impact, Canapino's car was damaged to the point where he could no longer steer or slow it. As a result, Canapino hit the already stricken car of O'Ward, causing Canapino to briefly become airborne. None of the drivers involved were injured in the accident.{{cite web|url=https://www.nbcsports.com/video/pato-oward-indy-500-hopes-dashed-lap-192-indianapolis-motor-speedway|title=O'Ward's Indy 500 hopes dashed on Lap 192|date=May 28, 2023|accessdate=May 28, 2023|website=nbcsports.com|publisher=NBC Universal|archive-date=May 28, 2023|archive-url=https://web.archive.org/web/20230528212607/https://www.nbcsports.com/video/pato-oward-indy-500-hopes-dashed-lap-192-indianapolis-motor-speedway|url-status=live}}

The leaders crossed the start/finish line, accepting the yellow with 7 laps to go. With another major cleanup needed, IndyCar officials again decided to put the red flag out again. The next time by, the field was parked in the pits under red. At the time of the second red, Newgarden led Ericsson with Santino Ferrucci third.

The cars rolled from the pit with six laps to go. After two laps under yellow, the green came out with four laps to go. Ericsson immediately passed Newgarden, but another accident occurred just as Ericsson moved ahead. As cars exited turn four coming to the green flag, a five- car accident involving Christian Lundgaard, Ed Carpenter, Benjamin Pedersen, Graham Rahal, and Marco Andretti occurred, bringing out another caution period. IndyCar officials made the decision to red flag the race for a third time - the first time in Indianapolis 500 history that three late-race red flags occurred. As the red flag came with only two laps remaining in the race, officials decided that the race would restart as soon as cars reached the start finish line again for the final lap.

The cars rolled from the pits one last time with two laps remaining. This provided them with just one lap to warm up their car and warm up their tires. The first time around racing resumed with the green flag and white flag flying together. It was the final lap with Ericsson getting an initial jump on Newgarden going into turn one. Newgarden was able to catch up to Ericsson and made a slingshot pass for the lead down the backstraight. He stayed in front for the remainder of the lap to win, securing his first Indianapolis 500 victory in his 12th start in the event. Newgarden's victory was the first for an American driver since 2016, while it was the 19th Indianapolis 500 victory for Team Penske. After winning, Newgarden stopped on the front straight, climbed from his car, then climbed through a gap in the catch fencing to celebrate with fans before returning for the official celebration ceremony in the winners circle.{{cite web|url=https://www.indycar.com/news/2023/05/05-28-500-lead|title=Newgarden Earns First Indianapolis 500 Win in Wild Finish|first=Paul|last=Kelly|date=May 28, 2023|accessdate=May 28, 2023|website=IndyCar.com|publisher=Brickyard Trademarks, LLC.|archive-date=May 28, 2023|archive-url=https://web.archive.org/web/20230528213140/https://www.indycar.com/news/2023/05/05-28-500-lead|url-status=live}} In winning, Newgarden became the first driver from Tennessee to take victory in the 500.{{cite web|url=https://racer.com/2023/05/28/newgarden-ericsson-ferrucci-generate-surprising-stats-at-indy/|title=Newgarden, Ericsson, Ferrucci generate surprising stats at Indy|first=David|last=Malsher-Lopez|date=May 28, 2023|accessdate=May 29, 2023|website=Racer.com|publisher=Racer Media & Marketing, Inc.|archive-date=May 28, 2023|archive-url=https://web.archive.org/web/20230528234609/https://racer.com/2023/05/28/newgarden-ericsson-ferrucci-generate-surprising-stats-at-indy/|url-status=live}} Newgarden earned $3.666 million for winning from a record purse of $17,021,500.{{cite web|url=https://www.indycar.com/news/2023/05/05-29-indy500-purse|title=Indianapolis 500 Purse Reaches New Peak for Second Year in a Row|date=May 29, 2023|accessdate=May 29, 2023|website=IndyCar.com|publisher=Brickyard Trademarks, LLC.}} As well, his win made Caitlyn Brown, his left-front tire changer, the first known woman to be part of an over-the-wall tire-changing pit crew for a driver while that driver won the Indy 500.{{Cite web|url=https://news.yahoo.com/penske-caitlyn-brown-becomes-first-225546942.html|title=Penske’s Caitlyn Brown becomes first female crew member to win Indy 500|date=May 28, 2023|website=Yahoo News}} Second-place finisher Marcus Ericsson became the first defending winner to finish second since Hélio Castroneves in 2003.

Despite being involved in the final accident, Benjamin Pedersen was the highest finishing rookie in the race in 21st and was named Rookie of the Year for 2023.

The decision to red flag the race for a one-lap run to the finish was met with criticism from runner-up finisher Marcus Ericsson, who called the ruling "unfair and dangerous" and cited that IndyCar had never done a restart in that way any time prior.{{cite web|url=https://www.motorsport.com/indycar/news/marcus-ericsson-indy-500-restart-unfair-dangerous/10475013/|title=Ericsson says final-lap Indy 500 restart was "unfair and dangerous"|first=Charles|last=Bradley|date=May 28, 2023|accessdate=May 28, 2023|website=Motorsport.com|publisher=Motorsport Network|archive-date=May 28, 2023|archive-url=https://web.archive.org/web/20230528213622/https://www.motorsport.com/indycar/news/marcus-ericsson-indy-500-restart-unfair-dangerous/10475013/|url-status=live}} Other competitors, such as 3rd place finisher Santino Ferrucci and 16th place finisher Tony Kanaan felt that IndyCar's decision was the correct one, citing complaints from previous editions of the race about ending under caution periods.{{cite web|url=https://racer.com/2023/05/28/ericsson-slams-final-indy-500-red-flag-call-others-disagree/|title=Ericsson slams final Indy 500 red flag call, others disagree|first=Mark|last=Glendenning|date=May 28, 2023|accessdate=May 28, 2023|website=Racer.com|publisher=Racer Media & Marketing, Inc.|archive-date=May 28, 2023|archive-url=https://web.archive.org/web/20230528222236/https://racer.com/2023/05/28/ericsson-slams-final-indy-500-red-flag-call-others-disagree/|url-status=live}}
