Thomas Peterffy

Peterffy was born in Budapest, Hungary, on September 30, 1944, in a hospital basement during a Russian air raid.{{Cite web|url=https://www.bloomberg.com/news/photo-essays/2010-12-06/twenty-billionaires-who-started-with-nothing|title=Twenty Billionaires Who Started With Nothing|date=December 6, 2010|website=www.bloomberg.com|access-date=December 13, 2019|archive-date=December 14, 2019|archive-url=https://web.archive.org/web/20191214003220/https://www.bloomberg.com/news/photo-essays/2010-12-06/twenty-billionaires-who-started-with-nothing|url-status=live}} His father emigrated to the U.S. after the failure of the Hungarian Revolution in 1956. Peterffy left his engineering studies in Hungary and emigrated to the United States to join his father in New York in 1965.{{cite news |url=https://www.forbes.com/profile/thomas-peterffy/ |title=Forbes profile: Thomas Peterffy |work=Forbes |accessdate=January 17, 2021 |archive-date=January 3, 2021 |archive-url=https://web.archive.org/web/20210103064154/https://www.forbes.com/profile/thomas-peterffy/ |url-status=live }} When his father, who was living with his second wife, did not have room to accommodate his son, he gave Thomas $100 and told him to "make something of himself".{{Cite news|url=https://www.forbes.com/profile/thomas-peterffy/|title=Thomas Peterffy|work=Forbes|access-date=December 13, 2019|archive-date=December 20, 2019|archive-url=https://web.archive.org/web/20191220032231/https://www.forbes.com/profile/thomas-peterffy/|url-status=live}}

When he moved to New York City, he did not speak English. Peterffy began his career in the U.S. as an architectural draftsman working on highway projects for an engineering firm. At this firm, he volunteered to program a newly purchased computer. Of his background in programming, Peterffy said, "I think the way a CEO runs his company is a reflection of his background. Business is a collection of processes, and my job is to automate those processes so that they can be done with the greatest amount of efficiency".

Peterffy left his career designing financial modeling software and bought a seat on the American Stock Exchange to trade equity options. During his career in finance, he has consistently pushed to replace manual processes with more efficient automated ones. He wrote code in his head during the trading day and then applied his ideas to computerized trading models after hours. Peterffy created a stir among traders by introducing handheld computers onto the trading floor in the early 1980s. His business related to his AMEX seat eventually developed into Interactive Brokers. He stepped down as CEO in 2019.{{Cite web|url=https://www.fool.com/investing/2019/01/14/interactive-brokers-ceo-steps-down-what-investors.aspx|title=Interactive Brokers' CEO Steps Down: What Investors Need to Know|last=Duberstein|first=Billy|date=January 14, 2019|website=The Motley Fool|access-date=January 16, 2020|archive-date=July 28, 2020|archive-url=https://web.archive.org/web/20200728085609/https://www.fool.com/investing/2019/01/14/interactive-brokers-ceo-steps-down-what-investors.aspx|url-status=live}}

In 2021, Interactive Brokers moved its European headquarters in London and outsourced its operations to two new continental centers. Thereafter, their Western European clients were served by a subsidiary in Ireland, while their Central European operations were based in Budapest. According to Peterffy, he chose Budapest because he was convinced that the Hungarian language and the “unique Hungarian logic” would result in above-average profitability; he also wanted to pay off the debt he owed to his native Hungary. The Budapest-based subsidiary, Interactive Brokers Central Europe Zrt., was established in Hungary and became a member of the Budapest Stock Exchange (BSE) upon its incorporation.{{Cite web|title=Interjú a leggazdagabb magyarral - "Ragaszkodtam hozzá, hogy Budapesten legyen a régiós központ"|url=https://www.portfolio.hu/uzlet/20210603/interju-a-leggazdagabb-magyarral-ragaszkodtam-hozza-hogy-budapesten-legyen-a-regios-kozpont-485726|access-date=June 9, 2021|website=Portfolio.hu|date=3 June 2021|language=hu|archive-date=June 9, 2021|archive-url=https://web.archive.org/web/20210609013547/https://www.portfolio.hu/uzlet/20210603/interju-a-leggazdagabb-magyarral-ragaszkodtam-hozza-hogy-budapesten-legyen-a-regios-kozpont-485726|url-status=live}}{{Cite web|date=June 1, 2021|title=Péterffy Tamás a BÉT-en: a grundon nevelkedett, ma már messze ő a leggazdagabb magyar|url=https://telex.hu/gazdasag/2021/06/01/peterffy-tamas-a-bet-en-a-grundon-nevelkedett-ma-mar-messze-o-a-leggazdagabb-magyar|access-date=June 9, 2021|website=telex|language=hu|archive-date=June 9, 2021|archive-url=https://web.archive.org/web/20210609013545/https://telex.hu/gazdasag/2021/06/01/peterffy-tamas-a-bet-en-a-grundon-nevelkedett-ma-mar-messze-o-a-leggazdagabb-magyar|url-status=live}}

Peterffy, alongside Mark Penn, Victor Ganzi, Josh Harris, and James Tisch, contributed to a $50 million investment fund in The Messenger, a news website that launched in May 2023.{{cite web |last1=Fischer |first1=Sara |title=The Messenger to launch May 15 with 150 journalists |url=https://www.axios.com/2023/05/02/messenger-launch-may-150-journalists |website=Axios |access-date=May 21, 2023 |date=May 2, 2023 |archive-date=May 13, 2023 |archive-url=https://web.archive.org/web/20230513133316/https://www.axios.com/2023/05/02/messenger-launch-may-150-journalists |url-status=live }}{{cite web |last1=Mullin |first1=Benjamin |title=The Messenger, a Media Start-Up, Aims to Build a Newsroom Fast |url=https://www.nytimes.com/2023/03/10/business/media/the-messenger-jimmy-finkelstein.html |website=The New York Times |access-date=May 21, 2023 |date=March 10, 2023 |archive-date=May 8, 2023 |archive-url=https://web.archive.org/web/20230508095627/https://www.nytimes.com/2023/03/10/business/media/the-messenger-jimmy-finkelstein.html |url-status=live }}

In 1999, Peterffy was influential in persuading the Securities and Exchange Commission (SEC) that U.S. options markets could be linked electronically, which would ensure that investors receive the best possible options prices. He has also testified before the United States Senate Banking Subcommittee on Securities, Insurance, and Investment about adding banking regulations.

During the 2012 United States presidential campaign, Peterffy created political ads supporting the Republican Party.{{cite web |url=https://www.youtube.com/watch?v=UnX7TNFIELg |title=Thomas Peterffy - Freedom To Succeed |date=October 10, 2012 |publisher=YouTube |accessdate=October 10, 2012 |archive-date=October 11, 2012 |archive-url=https://web.archive.org/web/20121011164517/http://www.youtube.com/watch?v=UnX7TNFIELg |url-status=live }} Peterffy bought millions of dollars of air time on networks such as CNN, CNBC, and Bloomberg. The ads consisted of a minute-long spot narrated by Peterffy, warning against creeping socialism in the United States. The ads were out of the ordinary, because Peterffy was not a candidate and did not buy the ads through a 527 group, but instead paid for them directly.{{cite news |author=Neil Vigdor |url=http://www.ctpost.com/local/article/Greenwich-man-splurging-on-his-own-ads-3944832.php#ixzz29NAvLKWw |title=Greenwich man splurging on his own ads |work=Connecticut Post |accessdate=October 16, 2012 |archive-date=September 26, 2013 |archive-url=https://web.archive.org/web/20130926152228/http://www.ctpost.com/local/article/Greenwich-man-splurging-on-his-own-ads-3944832.php#ixzz29NAvLKWw |url-status=live }}

In the spot, Peterffy said, "America's wealth comes from the efforts of people striving for success. Take away their incentive with badmouthing success and you take away the wealth that helps us take care of the needy. Yes, in socialism the rich will be poorer, but the poor will also be poorer. People will lose interest in really working hard and creating jobs."{{cite web |url=https://www.foxnews.com/politics/hungarian-born-billionaire-makes-anti-socialism-case-in-tv-ad/#ixzz29NCrlkXK |title=Hungarian-born billionaire makes anti-socialism case in TV ad |publisher=Fox News |access-date=October 16, 2012 |archive-date=October 15, 2012 |archive-url=https://web.archive.org/web/20121015030213/http://www.foxnews.com/politics/2012/10/12/hungarian-born-billionaire-makes-anti-socialism-case-in-tv-ad/#ixzz29NCrlkXK |url-status=live }}

Peterffy's ad received mixed responses. Joshua Green, writing for Bloomberg Businessweek, said "The ad, while slightly ridiculous, is deeply sincere and also quite affecting." Green also asked Peterffy whether the comparison between the United States and Hungary made in the ad was a fair one: "[Peterffy] couldn't really think that the U.S. was turning into socialist Hungary, could he? The government isn't suppressing speech and throwing political opponents in jail. No, he conceded, it wasn't. But it sure feels like that's the path we're on."{{cite news|url=http://www.businessweek.com/articles/2012-10-19/the-cheerful-billionaire-who-thinks-obamas-a-socialist |archive-url=https://web.archive.org/web/20121021211229/http://www.businessweek.com/articles/2012-10-19/the-cheerful-billionaire-who-thinks-obamas-a-socialist |url-status=dead |archive-date=October 21, 2012 |title=The Cheerful Billionaire Who Thinks Obama's a Socialist |newspaper=Bloomberg Business Week |date=October 19, 2012 |publisher=BloombergBusinessweek |accessdate=November 4, 2012}} Politico said that it could have been influential in Ohio due to its large Hungarian American population.{{cite web | author = Parti, Tarini | url = http://www.politico.com/news/stories/1112/83243_Page2.html | title = Billionaire Thomas Peterffy's 'socialist' ads raise questions | publisher = Politico | date = November 3, 2012 | accessdate = November 5, 2012 | archive-date = November 5, 2012 | archive-url = https://web.archive.org/web/20121105232848/http://www.politico.com/news/stories/1112/83243_Page2.html | url-status = live }}

Voter registration records in Connecticut show that Peterffy has been registered as an independent voter. He donated over $60,000 to the Republican National Committee in 2011 and $100,000 to a pro-Donald Trump political group during the 2016 United States presidential election.{{cite news|last1=Coffey|first1=Brendan|title=Hillary Clinton Is Outraising Trump 20-to-1 Among Billionaires|url=https://www.bloomberg.com/news/articles/2016-09-26/billionaire-donors-led-by-soros-simons-favor-clinton-over-trump|accessdate=October 10, 2016|work=Bloomberg Business News|date=September 26, 2016|archive-date=October 11, 2016|archive-url=https://web.archive.org/web/20161011185918/http://www.bloomberg.com/news/articles/2016-09-26/billionaire-donors-led-by-soros-simons-favor-clinton-over-trump|url-status=live}}{{cite web |url=https://www.opensecrets.org/donor-lookup/results?name=peterffy&cycle=&state=&zip=&employ=&occupation=&jurisdiction=&cand=trump&type= |title=Donor Lookup |author= |date= |website=OpenSecrets.org |publisher= |access-date=January 25, 2023 |archive-date=January 25, 2023 |archive-url=https://web.archive.org/web/20230125182606/https://www.opensecrets.org/donor-lookup/results?name=peterffy&cycle=&state=&zip=&employ=&occupation=&jurisdiction=&cand=trump&type= |url-status=live }}

Discussing the 2016 election in 2021, he said "I am actually not a Trump fan at all. I hope he won't run again." Peterffy also then said that the Republican Party is "completely adrift". Peterffy says he did not vote for Trump in the 2016 Republican Party presidential primaries, but supported Trump's bid for the presidency after Trump became the Republican nominee due to Trump's opposition to socialism and collectivism. Peterffy lives near Mar-a-Lago, Trump's Florida estate, and is a member of the Mar-a-Lago Club.{{Cite news |title=Election Denial and $16 Spritzers: Welcome to Florida's Trump Coast |author=Joshua Green |work=Bloomberg Business News |date=June 10, 2021 |access-date=June 13, 2021 |url=https://www.bloomberg.com/news/features/2021-06-10/florida-s-trump-coast-near-mar-a-lago-houses-beating-heart-of-gop |archive-date=June 13, 2021 |archive-url=https://web.archive.org/web/20210613000517/https://www.bloomberg.com/news/features/2021-06-10/florida-s-trump-coast-near-mar-a-lago-houses-beating-heart-of-gop |url-status=live |url-access=subscription}}

In late 2023, Peterffy, as well as other wealthy Republican donors, distanced themselves from Trump. Peterffy said in December 2023 that, “the street still hopes for somebody else", and expressed hope for a brokered convention.{{Cite web |last=Sutton |first=Sam |date=2023-12-11 |title=Wall Street donors dreamed of a Trump alternative.

However, as events unfolded, and voters across America continued to support Trump, wealthy Republican donors, including Peterffy, who had distanced themselves from him earlier, began to change their minds. For many, even though he was in no way their first choice, they nevertheless saw him as preferable to Democratic leadership.{{Cite magazine |last=Glasser |first=Susan B. |date=2024-10-18 |title=How Republican Billionaires Learned to Love Trump Again |url=https://www.newyorker.com/magazine/2024/10/28/how-republican-billionaires-learned-to-love-trump-again |access-date=2025-01-08 |magazine=The New Yorker |language=en-US |issn=0028-792X }}

On December 11, 2024, in the aftermath of the election, Peterffy sat down for an interview with Bloomberg's Sonali Basak at a Goldman Sachs Group Inc. conference. Basak mentioned at the beginning of the interview that Peterffy had donated to Trump both in 2020 and in 2024, and Peterffy stated that, "having grown up in a socialist country I came to a conviction early on in my life that a free market economy is the only way to efficiently run a society", and, "I've always been a Republican all my life." He said that, "I'm very happy that this is the outcome that we had this election time."
