Terence A. "Terry" Duffy is an American business executive who serves as the Chairman and Chief Executive Officer of CME Group, the world's largest financial derivatives exchange. Duffy grew up on the South Side of Chicago, at the corner of 105th Street and St. Louis Avenue in the Mount Greenwood neighborhood, and rose from the trading floors of the Chicago Mercantile Exchange to lead a global financial institution that facilitates trillions of dollars in daily transactions across asset classes including interest rates, equity indexes, foreign exchange, energy, agricultural commodities, metals, and, increasingly, cryptocurrencies. His career at the CME spans more than four decades, beginning in the open-outcry trading pits and culminating in his role overseeing the exchange's transformation into a predominantly electronic marketplace. In recognition of his leadership at CME Group, Duffy was named one of Crain's Chicago Business Newsmakers of the Year.

Early Life

Terry Duffy was raised in the Mount Greenwood neighborhood on the South Side of Chicago, Illinois. His boyhood home was located at the corner of 105th Street and St. Louis Avenue, a location Duffy has returned to publicly and identified as the place "where it all started." Mount Greenwood, a predominantly working-class and middle-class neighborhood on Chicago's far South Side, was home to many families with backgrounds in public service, trades, and labor. Duffy's upbringing in this environment shaped his approach to business and leadership.

Details of Duffy's parents, siblings, and family background beyond his Chicago South Side roots have not been extensively documented in the available sources. However, Duffy has spoken publicly about his modest origins and the path that took him from the neighborhood streets of Mount Greenwood to the upper echelons of global finance.

Career

Early Career in the Trading Pits

Terry Duffy began his career at the Chicago Mercantile Exchange (CME) approximately 45 years ago, starting in the open-outcry trading pits that were, at the time, the primary venue for buying and selling futures and options contracts. The trading pits were a defining feature of Chicago's financial landscape throughout the twentieth century, where traders used hand signals and shouted orders to execute transactions in commodities, currencies, and financial instruments. Duffy's early experience on the trading floor provided him with a ground-level understanding of how derivatives markets operated and the needs of the traders, brokers, and clearing firms that comprised the exchange's membership.

During his years in the pits, Duffy gained familiarity with the mechanics of price discovery, risk management, and the culture of the exchange community. This period of his career would later inform his perspective as the exchange transitioned away from floor-based trading toward electronic platforms — a transformation that became one of the most consequential and, at times, contentious developments in the history of the CME.

Rise to Leadership at CME

Duffy rose through the ranks of the CME's governance structure, eventually becoming Chairman of the exchange. His ascent reflected both his standing among the exchange's membership — many of whom were fellow floor traders — and his ability to navigate the political dynamics of a member-owned institution. As the CME evolved from a mutual organization into a publicly traded company, Duffy's role expanded considerably.

CME Group was formed through a series of mergers and acquisitions that consolidated several of the most important derivatives exchanges in the United States under a single corporate umbrella. The Chicago Mercantile Exchange merged with the Chicago Board of Trade (CBOT) in 2007, and CME Group subsequently acquired the New York Mercantile Exchange (NYMEX) and the Commodity Exchange, Inc. (COMEX) in 2008. Duffy played a central role in the leadership of the combined entity, serving as Executive Chairman and later assuming the additional title of Chief Executive Officer.

As Chairman and CEO, Duffy became the public face of CME Group, representing the company before regulators, policymakers, investors, and the media. He has presented at numerous financial industry conferences, including the Piper Sandler Global Exchange and Trading Conference in June 2025.

Transition to Electronic Trading

One of the most significant developments during Duffy's tenure has been the CME's transition from open-outcry pit trading to electronic trading. This shift, which unfolded over several decades, fundamentally altered the exchange's operations and the livelihoods of thousands of floor traders who had conducted business in the pits.

In July 2025, Duffy was called to testify in a $2.1 billion lawsuit brought by former pit traders against the exchange. The suit put the CME's historical transition to electronic trading on trial, and Duffy — described as "the longtime head of CME, who started his career in the pits 45 years ago" — was required to answer questions about how the transition was managed and its impact on the exchange's floor-based membership. The case highlighted the tensions that accompanied the exchange's modernization, as many former pit traders contended that the shift to electronic platforms had adversely affected their businesses and livelihoods.

Duffy's position at the intersection of the old and new CME — a leader who began his career shouting orders on the trading floor and went on to oversee a technology-driven global exchange — has made him a central figure in the narrative of Chicago's financial evolution.

Expansion into Retail Trading

Under Duffy's leadership, CME Group has pursued strategies to broaden access to its markets beyond traditional institutional participants. In October 2025, Duffy discussed the exchange's efforts to expand into retail trading, including a partnership with FanDuel that would allow individuals to place market-based bets through the sports betting platform.

This initiative represented a departure from the CME's traditional focus on institutional and professional traders. By partnering with a consumer-facing brand like FanDuel, CME Group sought to introduce derivatives products to a new generation of retail participants who may have been more familiar with sports wagering than with futures and options markets. The retail trading push reflected broader trends in the financial industry, where exchanges and brokerages increasingly competed for individual investors following the growth of commission-free trading platforms and the retail trading surge that gained prominence in the early 2020s.

Cryptocurrency and Digital Assets

Duffy has also positioned CME Group at the forefront of institutional involvement in cryptocurrency and digital asset markets. CME Group launched Bitcoin futures contracts in December 2017, becoming one of the first major regulated exchanges to offer derivatives products tied to cryptocurrencies. The exchange subsequently introduced Ethereum futures and options, as well as micro-sized cryptocurrency contracts designed for smaller traders.

In February 2026, Duffy indicated that CME Group was exploring the launch of its own digital token, referred to informally as "CME Coin," which could operate on a decentralized network. The announcement drew significant attention from both the traditional finance and cryptocurrency communities, as it signaled that one of the most established institutions in global finance was considering a direct entry into the tokenized economy.

According to reporting by CryptoRank, Duffy unveiled what were described as "groundbreaking institutional cryptocurrency plans" for CME Group, further detailing the exchange's ambitions in the digital asset space. The potential introduction of a CME-issued token represented a convergence of traditional exchange infrastructure with emerging blockchain technology, and positioned CME Group as a bridge between regulated financial markets and the decentralized finance ecosystem.

LPGA Sponsorship and Sports Partnerships

CME Group under Duffy's leadership has maintained a prominent sponsorship presence in professional golf, particularly through its association with the LPGA Tour. The CME Group Tour Championship serves as the season-ending event on the LPGA Tour and is one of the most significant sponsorships in women's professional golf.

In November 2025, Duffy spoke publicly about the LPGA's television broadcasting changes and the organization's co-sponsored event with Golf Saudi. Duffy's willingness to comment on the LPGA's strategic direction reflected CME Group's role not merely as a financial sponsor but as an engaged partner with a stake in the governance and visibility of women's professional golf. The partnership with Golf Saudi, in particular, drew attention given the broader debate in professional sports about relationships with Saudi Arabian entities.

Recognition

Terry Duffy has received recognition from multiple media and business organizations for his leadership of CME Group. In early 2026, Crain's Chicago Business named Duffy one of its Newsmakers of the Year, citing his role as Chairman and CEO of CME Group. The Newsmakers of the Year designation by Crain's Chicago Business is given to individuals who have had a significant impact on the Chicago business community and beyond during the preceding year.

WGN-TV, a Chicago-based television station, produced a feature profile on Duffy as part of its "Chicago's Very Own" series, tracing his journey from his childhood home in Mount Greenwood to the executive suite of CME Group. The profile highlighted Duffy's South Side Chicago roots and the arc of his career from the trading pits to corporate leadership.

Duffy has also been a frequent presence at major financial industry events and conferences. In May 2025, CME Group announced that Duffy would present at the Piper Sandler Global Exchange and Trading Conference, one of the financial industry's notable gatherings focused on exchanges and trading infrastructure. His appearances at such conferences underscored his role as a leading voice in discussions about the future of financial markets, exchange regulation, and market structure.

His commentary has been sought by major financial media outlets including Bloomberg and CoinDesk, reflecting his influence in shaping public discourse around derivatives markets, retail trading access, and the integration of digital assets into institutional finance.

Legacy

Terry Duffy's career at CME Group encompasses one of the most transformative periods in the history of financial exchanges. His trajectory — from the open-outcry trading pits of the Chicago Mercantile Exchange to the chairman's office of a global, publicly traded exchange holding company — mirrors the broader evolution of derivatives markets from local, floor-based venues to electronic, interconnected global platforms.

Under Duffy's leadership, CME Group grew into the world's largest derivatives marketplace, offering products across virtually every major asset class. The exchange's expansion into cryptocurrency derivatives, its exploration of a proprietary digital token, and its push into retail trading through partnerships with consumer platforms like FanDuel reflect an institution that has continued to evolve under his direction.

The $2.1 billion lawsuit by former pit traders, in which Duffy was called to testify, illustrates the complexities and costs associated with the exchange's transformation. The case brought into public view the human dimension of technological change in financial markets — a transition that created enormous value for shareholders and electronic market participants while displacing the floor-based trading community that had been the exchange's foundation for over a century.

Duffy's South Side Chicago origins have been a recurring theme in media profiles and public appearances. His journey from 105th and St. Louis to the leadership of a Fortune 500 company has been cited as representative of the opportunities available in Chicago's financial industry and, more broadly, of the American tradition of upward mobility through commerce and markets.

As CME Group continues to navigate developments in digital assets, retail market access, regulatory changes, and global competition among exchanges, Duffy's leadership remains central to the institution's strategic direction and public identity.
