Moments that Define Citadel

For more than two decades we have delivered strong performance for our investors and clients, always seeking new ways to capitalize on market opportunities. With everything we achieve, we recognize the fundamental truths that inspire us to always keep pushing forward.

Leadership recognized

Citadel has earned widespread recognition from major industry observers. These honors include: high rankings in Institutional Investor’s Alpha – Hedge Fund Report Card; five Absolute Return Awards in 2016; Institutional Hedge Fund Manager of the Year from Institutional Investor magazine in 2015; and Hedge Fund of the Year from Risk Magazine in 2016.


Continued Focus on Performance

With over $26 billion investment capital as of March 1, 2017, Citadel remains focused on its objective of delivering consistently high risk-adjusted returns for its investors.


Championing market stability and integrity

In October 2012, Citadel Securities was selected to participate in an SEC market technology roundtable to speak in support of sound market structure. Citadel Securities’ recommendations informed regulators, exchanges and market participants as they implemented new safeguards in the era of automated trading.


Improving market structure

Citadel’s policy analysis and recommendations were cited more than 50 times in a landmark CFTC rule announced in December 2012. The rule, regarding clearing of interest rate swaps and credit default swaps, was a significant step in implementing Title VII of the Dodd-Frank Wall Street Reform and Consumer Protection Act.


Regaining the high-water mark

Citadel’s flagship funds fully recovered from the impact of the financial crisis, gaining back their losses in January 2012.


Expanding our potential

In the aftermath of the 2008 global financial crisis, Citadel sought new ways to scale its talent, expertise and capital to achieve performance for investors. The firm launched standalone funds across a number of strategies.


Raising the bar for investors

Citadel’s growth and success continued to earn widespread industry recognition. In 2008, Institutional Investor’s Alpha created the Hedge Fund Hall of Fame, with Citadel CEO Ken Griffin among the 14 inaugural inductees.


Focusing on opportunity amid crisis

In 2006, Citadel acquired large portions of Amaranth Advisors’ energy portfolio and Sowood’s credit portfolio, two hedge funds that were experiencing financial distress.

Expanding into the East

The addition of Citadel’s Hong Kong office in 2005 accelerated the firm’s participation in one of the world’s most compelling financial markets. Today, Citadel’s global offices include Chicago, New York, London, Hong Kong, San Francisco, Boston, Dallas, Greenwich, Houston and Toronto.


Crossing the $10 billion threshold

Just six years after surpassing the $1 billion mark, Citadel managed over $10 billion in investment capital on April 1, 2004. Continuing its rapid pace of growth, the firm expanded into the foreign exchange market.

Advancing market efficiency

To capture opportunity in the growth of automated trading, Citadel Securities was formed in 2002 with new execution services and market-making capabilities. The business was Citadel’s first offering beyond asset management, and rapidly made a visible impact on the industry. Citadel Securities achieved over 15% market share within 10 months, and would become a market share leader within a decade.1

Capturing energy’s potential

Citadel gained some of the brightest minds in the energy industry in 2001, when it hired experts from Aquila’s discontinued energy business. This expertise launched what would eventually become Citadel’s commodities business. Today, the breadth of Citadel’s commodities business includes the North American natural gas market and the European gas and power markets, as well as crude oil and refined products.


Mobilizing for a successful era

With $1 billion in investment capital by 1998 and a team of 100, Citadel’s growth had solidly positioned the firm for success in the coming economic growth years. Recognition came from the Alternative Investment Awards, which presented Citadel with its Relative Value/Arbitrage Award.

Fast track to global status

Strong performance and outstanding client service were hallmarks of the firm, even from its founding in 1990 as Wellington Financial Group. The firm initially focused on convertible bond arbitrage, but its performance excelled as it rapidly diversified and entered more markets around the world. In 1994, the firm officially named itself Citadel, establishing an identity that signifies strength and commitment across a spectrum of market environments.


Born of entrepreneurship

Armed with a fax machine, a personal computer, a telephone and $265,000 in capital, Ken Griffin set up a fund from his Harvard dorm room in 1987. From this modest but ambitious beginning, Griffin raised nearly $1 million and caught the attention of Frank Meyer, a hedge-fund pioneer and co-founder of Chicago-based Glenwood Partners. Griffin’s performance earned him the opportunity to establish what would one day become Citadel.
