CME Group, the derivatives exchange behemoth with a market cap exceeding $95 billion, is getting a new boss. Terry Duffy, who has been the face of CME for the better part of two decades, will hand the CEO title to current President and CFO Lynne Fitzpatrick effective March 1, 2027.

Duffy isn’t exactly cleaning out his desk. He’ll transition to the role of Executive Chairman, keeping a seat at the table while Fitzpatrick takes the operational wheel.

A 46-year run and the empire Duffy built

Terry Duffy first walked through CME’s doors in 1980. He became Chairman in 2002 and added the CEO title in 2016. In the years between, he orchestrated a series of acquisitions that turned CME from a major exchange into the dominant one.

The purchases of CBOT, NYMEX, and NEX stitched together an empire spanning interest rates, energy, metals, and foreign exchange. A partnership with Google Cloud modernized the exchange’s technology infrastructure. And under Duffy’s watch, CME pushed aggressively into electronic trading.
