Early life and education
Griffin was born in 1968 in Daytona Beach, Florida, the son of a building supplies executive.[6] His father had various jobs, and was a project manager for General Electric.[7] Griffin's grandmother, Genevieve Huebsch Gratz, inherited an oil business, three farms, and a seed business.[8]
Griffin grew up in Boca Raton, Florida, with some time[weaselwords] in Texas, and Wisconsin.[9] He went to middle school in Boca Raton[7] and Boca Raton Community High School, where he was the president of the math club.[9][10] In high school, Griffin ran a discount mail-order education software firm, EDCOM, out of his bedroom.[10] In a 1986 article in the Sun-Sentinel, he said he thought he would become a businessman or lawyer and that he believed the job market for computer programmers would significantly decrease over the coming decade.[10]
Griffin started at Harvard College in the fall of 1986.[9] That year, one of his first investments was to buy put options on Home Shopping Network, making a $5,000 profit.[11] He also invested in convertible arbitrage opportunities in convertible bonds.[9] Despite a ban on running businesses from campus, Griffin convinced school administrators to allow him to install a satellite dish on the roof of Cabot House, a dormitory, to receive stock quotes.[11][9] He also asked Terrence J. O'Connor, the manager of convertible bonds at Merrill Lynch in Boston, to open a brokerage account for him with $100,000 that Griffin had gotten from his grandmother, his dentist, and others.[7][9] His first fund launched in 1987 with $265,000, days after his 19th birthday.[9] The fund launched in time to profit from short positions on Black Monday.[9] Griffin graduated in 1989 with a degree in economics.[12]
Career
After graduating in 1989, Griffin moved to Chicago to work with Frank Meyer, founder of Glenwood Capital Investments.[13][14] Meyer allotted $1 million of Glenwood capital for Griffin to trade[14] and Griffin made 70% in a year.[9]
In 1990, Griffin founded Citadel LLC, with assets under management of $4.6 million, aided by contributions from Meyer.[14] His funds made 43% in 1991 and 40% in 1992.[11]
In the early 2000s, Griffin founded market maker Citadel Securities.[15][16]
In 2003, aged 34, Griffin was the youngest person on the Forbes 400, with an estimated net worth of $650 million.[17]
From the time of his second marriage to Anne Dias in 2003 until late 2009, Griffin was the lead investor in Aragon Global Management, a hedge fund run by his then wife. The fund was also seeded with money from Julian Robertson. Griffin lost 20% of his investment in the fund.[18]
In 2006, Citadel acquired the positions of Amaranth Advisors at a steep discount.[9]
During the 2007–2008 financial crisis, for 10 months, Griffin barred his investors from withdrawing money, attracting criticism.[2][19] At the crisis's peak, the firm was losing "hundreds of millions of dollars each week".[20] It was leveraged 7:1 and the biggest funds at Citadel finished 2008 down 55%, but rebounded with a 62% return in 2009.[9]
From Citadel LLC, Griffin earned $900 million in 2009,[21] $1.4 billion in 2014,[22] $600 million in 2016,[23] $1.4 billion in 2017,[24][25] $870 million in 2018,[26] $1.5 billion in 2019,[27] and $1.8 billion in 2020.[28]
In November 2020, according to Bloomberg News, Griffin's net worth surpassed $20 billion due to an increase in the value of Citadel, of which Griffin's stake was worth $11.2 billion.[29] Citadel Securities, a market maker, increased its profit to $2.36 billion during the first half of 2020 compared to $982 million for the same period in 2019, due to increased volatility, volume and retail trader engagement.[30][31]
In January 2021, Griffin attracted criticism for the role Citadel played in the GameStop short squeeze.[32] On January 25, it was announced that Citadel would invest $2 billion into Melvin Capital, which had suffered losses of more than 30% on account of its short positions, particularly on GameStop.[33][34][35] On January 28, Robinhood, an electronic trading platform favored by many traders involved in buying GameStop stock and options, announced that it would halt all purchases of GameStop securities and only allow these securities to be sold; the price of GME stock declined steeply shortly thereafter.[36] Because Robinhood receives a substantial portion of its revenue through a payment for order flow relationship with Citadel, 85% of which is owned by Griffin, many commentators criticized the potential for conflict of interest when the same entity both plays the role of market-maker and also participates in the market it makes; Griffin has been at the center of much discussion of this controversy.[37][38][39][40][41] On February 18, 2021, he testified before the House Financial Services Committee about his role in the GameStop controversy;[41][42] Griffin had donated money directly to four members of the committee, Republicans French Hill, Andy Barr, Ann Wagner, and Bill Huizenga.[41]

In November 2021, Griffin outbid a group of crypto investors to purchase the last privately held copy of the United States Constitution at auction for $43.2 million.

Griffin supported the University of Chicago's Center for Urban School Improvement, a program encouraging the construction of an inner-city charter high school,[6] and contributed to the Lurie Children's Hospital.[68]
In May 2022, The University of Chicago announced a $25 million donation from Griffin to launch an initiative design to train police managers and prevent neighborhood violence. The funds will aid in launching two community Safety Leadership Academies. The Policing Management Academy aims to professionalize departments by educating their leaders though coaching, accountability and data-driven decision making. This donation came after Griffin's $10 million donation to the Crime Lab in 2018 to implement an early intervention system to investigate citizen complaints.[70]
Arts
Griffin served on the board of trustees of the Museum of Contemporary Art, Chicago from 2000 to 2022.[71][72]
In July 2007, Griffin donated a $19 million addition to the Art Institute of Chicago designed by Renzo Piano and named Kenneth and Anne Griffin Court.[73] One of his paintings by Paul Cézanne was loaned to the institute.[6]
Griffin is a member of the Fourth Presbyterian Church of Chicago, where he was married.[78][79] In 2011, he donated $11.5 million of the $38.2 million needed to build a new chapel at the church.[78] The modern building is called "The Gratz Center" in honor of Griffin's grandparents.[78]

Political views and activities
In a 2012 interview with the Chicago Tribune, Griffin said that the rich actually have too little influence in politics.[89] He identified as a Ronald ReaganRepublican. He said the belief "that a larger government is what creates prosperity, that a larger government is what creates good" is wrong.[90]
In a November 2015 interview on CNBC, Griffin said he admires Scott Walker, calling him an "absolute champion of free markets and a champion of smaller government".[91]
In April 2016, because Citadel owned over 1 million shares of McDonald's, Griffin was the target of protestors supporting the Fight for $15.[92] In May 2017, he praised Donald Trump's efforts at tax and healthcare reform.[93]
In 2018, it was announced that Griffin had been appointed the national finance chair for the New Republican PAC fueling Rick Scott's Super PAC.[94]
In January 2019, Griffin was singled out by Elizabeth Warren on a Facebook post as someone who can pay her Ultra-Millionaire Tax.[98] During a March 2019 interview with David Rubenstein, he criticized Warren's proposals, saying, "soaking the rich doesn't work".[99]
In January 2020, Griffin was absent from a signing ceremony for the phase-one trade deal with China at the White House, for which Trump criticized him.[100][101]
In September 2020, Griffin wrote an op-ed published in the Chicago Tribune stating his opposition to Governor of IllinoisJ. B. Pritzker's "Fair Tax" proposal, which would change Illinois's income tax from a flat tax to a graduated tax.[102][103] In an October 2020 email to Citadel LLC's Chicago employees, Griffin criticized Pritzker's tax plan and alluded to the possibility of moving his company out of Illinois.[104][105]
After Hamas's October 7 attacks on Israel in 2023, Griffin contacted the Harvard Corporation leadership to demand a university response, including a condemnation of 30 student groups that signed a letter critical of Israel. He also supported statements made by fellow alumnus and donor Bill Ackman that his firm would not hire students who signed the letter.[108] In January 2024, Griffin expressed his discontent with Harvard's educational approach, saying that the university should focus on educating future leaders and problem solvers rather than getting lost in issues like microaggressions and DEI.[109] In May 2024, he criticized the "failed education system" for anti-Israel protests on campuses, urging Harvard to "embrace our Western values that have built one of the greatest nations in the world".[110]
Political contributions
Ken Griffin's federal political contributions since 1996
In a 2012 interview, Griffin said that people should be able to make unlimited contributions to politicians, but that the contributions should be public.[111]
Griffin was one of the primary backers of Future 45, a pro-Trump super PAC.[118] After Trump won the 2016 Republican nomination, Griffin did not contribute to his campaign.[119]
In March 2020, Griffin contributed $1 million to the 1820 PAC created to support the reelection of U.S. Senator Susan Collins.[121] In late 2020, he donated another $500,000 to the 1820 PAC.[122]

Kilbride, a Democrat on the Supreme Court of Illinois.[128][129]
In 2021, Griffin donated $5 million to Ron DeSantis, the governor of Florida.[133] His donations to DeSantis prompted criticism of a possible conflict of interest when DeSantis began promoting Regeneron Pharmaceuticals' therapeutic treatment for COVID-19.[134][135][136][137] DeSantis has encouraged such monoclonal antibody treatment for COVID-19, which can treat people after they get sick and reduce hospitalization.[138] Shares in Regeneron were a $16 million investment by Griffin's hedge fund.[139][140] The fund denied any conflict of interest, noting that it had much larger investments in vaccine makers Pfizer and Moderna.[134][135][141][137] Likewise, a DeSantis spokesperson said that any suggestion of corruption over this connection to Griffin via Regeneron was illogical.[140] Griffin has at times criticized DeSantis, for example saying, "I don't appreciate Governor DeSantis going after Disney's tax status".[142]

Griffin denied her request but agreed to pay $45,000 for a winter vacation.[168][169][151] The couple settled their divorce out of court in October 2015, just hours before a public trial over the prenuptial agreement was set to begin.[170][154] As part of the divorce, Griffin paid $11.75 million to buy out his wife's interest in their Chicago penthouse.[171] He and Dias-Griffin maintain joint custody of their children.[154][172][173][174][160]

The space was "raw space", meaning Griffin had to build it out.[196][197][198] Several New York real estate experts have said that the purchase helped fuel legislation that increased taxes on luxury homes in New York.[199][200] During an interview with David Rubenstein, Griffin said that the purchase represented the possibility of making New York City his home in the future.[99]

Withdrawn fraud accusation
In June 2006, Rush E. Simonson, claiming to be Griffin's mentor, filed a fraud case (2006-L-005997) against Griffin, alleging that he was entitled to a percentage of Citadel's profits for creating a computer program upon which Citadel was founded.[207][208] In court filings, Simonson said that he first befriended Griffin in 1982 as a computer salesman. The two struck up a business partnership in convertible-arbitrage. Griffin provided the trading savvy, working both out of his Harvard dorm room and at home in Florida, while Simonson allegedly created the computer program that served as its technological backbone. According to the suit, Griffin struck a deal with a prominent Chicago investor in the late 1980s. As Griffin and Simonson began to unwind their partnership, the suit claimed, Griffin instead began to lay the foundations of what would become Citadel. In doing so, Griffin allegedly improperly took the program that Simonson had created. Simonson also said in his lawsuit that Griffin did not give him a cut of Citadel's profits. In January 2007, he dropped the lawsuit and apologized to Griffin.[209][210]
