Citadel LLC (previously known as Citadel Investment Group, LLC) is a global American hedge fund and financial services enterprise established in 1990 by Kenneth Griffin. As of 2025, it oversees assets exceeding $65 billion and employs over 2,900 professionals,[1] with its main office located in Miami, Florida[2] and additional branches throughout North America, Asia, and Europe. Griffin, who serves as founder, CEO, and Co-CIO, holds roughly 85% ownership in the firm.[3] By December 2022, Citadel ranked among the world's most lucrative hedge funds, having generated $74 billion in net profits since its inception—earning recognition as the top-performing hedge fund ever according to CNBC.[4][5]

Although both founded and predominantly owned by Griffin, Citadel LLC functions independently from the market-making firm Citadel Securities.[6]

Founding, 1990–2000

Griffin began trading convertible bonds while still a student at Harvard in 1987. After earning his economics degree, he worked at Glenwood Partners before establishing Citadel with an initial capital of $4.6 million. Originally called Wellington Financial Group after its primary fund, the company rebranded to Citadel in 1994. Within eight years, assets under management surpassed $2 billion.

In 1998, Citadel introduced investor terms that greatly limited capital withdrawals. This approach enabled the firm to act as one of the few buyers during the Long Term Capital Management crisis, acquiring assets from struggling hedge funds.

2001–2010

Following Enron's collapse in 2001, Griffin hired energy traders from the company, assembling a team of traders, meteorologists, and analysts to develop one of the largest energy trading divisions in the sector.

In 2006, Citadel collaborated with JP Morgan Chase to purchase the energy portfolio of the defunct hedge fund Amaranth Advisors, which had lost 65% (approximately $6 billion) of its assets. Later that year in November, Citadel issued $2 billion worth of investment-grade bonds to obtain financing at a reduced cost.

In 2007, Citadel invested $2.5 billion into E-Trade, acquiring securitized subprime mortgages, collateralized debt obligations (CDOs), second lien loans, senior unsecured notes, and a 19.99% stake in E-Trade’s common stock along with a seat on its board. The firm divested its remaining shares in E*Trade by 2013.

During the 2008 financial crisis, Griffin restricted investor redemptions for ten months amid widespread criticism. At the height of the turmoil, Citadel was experiencing weekly losses amounting to hundreds of millions, leveraged at a ratio of 7:1, with key funds declining by 55% that year. The company recovered strongly with a 62% gain in 2009.

2011–2020

On January 17, 2012, Citadel's primary funds, Citadel Kensington Global Strategies Fund Ltd and Citadel Wellington LLC, exceeded their previous peak values, recovering half of the assets lost during the 2008 financial crisis. This milestone allowed Citadel to reinstate client fee charges and profit-sharing arrangements. Under Ken Griffin's direction, Citadel set itself apart from rivals by pursuing rapid growth following the 2008 downturn. Between early 2014 and mid-2015, assets under management expanded by $10 billion—from $16 billion to $26 billion—supported by a 29% increase in core hedge fund performance along with fresh capital inflows. In January 2020, Citadel Securities reached a $97 million settlement with Chinese regulatory authorities, bringing an extended investigation to a close.

In 2014, Citadel became the inaugural foreign hedge fund to complete yuan fundraising under a program permitting Chinese investors to access overseas hedge funds.

Amid the July 2020 COVID-19 pandemic, Citadel adapted its internship program by leasing an upscale resort in Wisconsin to establish a quarantine "bubble" for more than 100 interns, enabling safe in-person participation despite public health restrictions.

2021–present

In January 2021, Citadel and Point72 Asset Management jointly injected $2.75 billion into Melvin Capital after it suffered a 53% loss owing to the GameStop short squeeze.

Citadel ranked second among leading money managers in net gains for the year 2021.

On June 23, 2022, Ken Griffin announced plans to relocate Citadel’s headquarters to Miami, Florida, citing more favorable business conditions and concerns about increasing crime rates in Chicago.

In December 2022, Citadel entered an agreement with Vornado Realty Trust and Rudin Management Co. to master lease a new $1.2 billion office tower standing 1500 feet tall on Park Avenue in Midtown Manhattan, designating it as its new New York City headquarters.

Citadel’s hedge fund division reported record revenues near $28 billion in 2022, returning $16 billion to clients—a historic annual return for both founder Kenneth Griffin and the hedge fund industry. This achievement enabled Citadel to overtake Bridgewater as the most profitable hedge fund ever according to LCH Investments.

In 2023, Citadel distributed approximately $7 billion in profits back to clients, equating to roughly a 15% return for its flagship fund.

By June 2024, Citadel managed assets exceeding $63 billion, ranking as the eleventh largest hedge fund manager worldwide and second among multi-strategy hedge funds. Its portfolio of hedge funds continues to be among the largest and most successful globally.

Investment strategies

Citadel operates funds spanning equities, commodities, fixed income, quantitative approaches, and credit markets.

Reinsurance

Established in 2004, Citadel launched CIG Reinsurance Ltd (CIG Re), a Bermuda-based catastrophe reinsurer capitalized with $450 million. The firm also initiated New Castle Re in 2005 with $500 million in capital to take advantage of elevated reinsurance pricing following Hurricane Katrina’s impact on property insurance costs. By 2006, roughly 10% of Citadel’s assets were allocated across these two reinsurance vehicles.

Due to an inability to obtain a financial strength rating that would enhance competitiveness, Citadel ceased operations of CIG Re in November 2008. Subsequently, in January 2009, New Castle Re was placed into run-off status as Citadel exited the reinsurance sector.

Risk management

Citadel's approach to risk management emphasizes the allocation of risk capital, monitoring stress exposures, and overseeing liquidity. The firm's dedicated risk management center tracks more than 50,000 financial instruments across its portfolios using 36 different monitoring screens. Each day, Citadel performs around 500 stress tests that simulate various economic, geopolitical, and market disturbances, analyzing over 500 extreme "doomsday scenarios" to identify potential vulnerabilities.

In 2014, Citadel received an A rating for its risk management practices in the Institutional Investor Hedge Fund Report Card.

Ben S. Bernanke, former chairman of the Federal Reserve, joined Citadel in April 2015 as a senior adviser focusing on global economic and financial matters. Joanna Welsh took on the role of Chief Risk Officer in January 2017.

Former companies

Citadel Solutions functioned as the firm's fund-administration division.

Founded in 2009, Citadel Technology operated as a fully owned but independently managed affiliate, offering investment management software developed internally at Citadel to external firms and funds. In 2013, it formed a partnership with REDI, integrating Citadel's order management system (OMS) with REDI's execution management system (EMS).

Aptigon Capital was established in 2016 after Citadel onboarded 17 portfolio managers from the shuttered hedge fund Visium Asset Management. Initially led by Richard Schimel, leadership transitioned to Eric Felder in 2018. The unit ceased operations in 2019 following Felder’s exit.

Citadel ownership

In November 2006, Citadel became only the second hedge fund to issue public bonds, successfully raising $2 billion through senior unsecured debt arranged by Lehman Brothers and Goldman Sachs.

Employees

By 2007, Citadel was known for one of Chicago’s highest rates of employee turnover, earning it the nickname "Chicago’s revolving door." The New York Times highlighted this reputation in 2010, although turnover levels were consistent with industry standards. In March 2015, employee feedback placed Citadel among the Top 10 Great Workplaces in Financial Services according to the Great Places to Work Institute.

Market advocacy

Citadel has been an active participant in regulatory discussions, promoting financial legislation related to market structure. In 1999, Congress repealed a provision of the Glass-Steagall Act that separated banking from trading activities—a move Griffin criticized as "one of the biggest fiascos of all time." After the 2008 financial crisis, Griffin and Citadel advocated for increased transparency in derivatives markets, often opposing other hedge funds and major firms. The firm also resisted Wall Street’s attempts to delay implementation of the Dodd–Frank Act. Griffin has supported breaking up "too big to fail" banks and advocated for separating their banking and trading functions.

Following Michael Lewis’s 2014 book Flash Boys, which alleged market manipulation by high-frequency traders, Griffin—who was not interviewed—addressed these accusations during a congressional hearing. He defended U.S. equity markets as among the "fairest, most transparent, resilient and competitive" globally. Griffin explained that high-frequency trading helps reconcile price discrepancies between stock options and their underlying equities at minimal cost. At an event hosted by Georgetown University, he dismissed Flash Boys as largely "fiction."
