The Chicago White Sox announced a multiyear agreement with CME Group, naming the derivatives exchange operator as the club’s inaugural jersey patch sponsor and Official Global Exchange Partner.
The partnership follows CME Group’s recent expansion into event contracts, including a joint venture with sports betting company FanDuel. The deal lets users trade simple yes-or-no contracts on financial markets, blending finance with sports‑linked wagering.

CME launched event contracts in September 2022, targeting retail traders with capped payouts, and the FanDuel agreement marked the company’s largest push toward mainstream audiences.
CME Group Becomes White Sox Sponsor
CME Group Chairman and Chief Executive Officer Terry Duffy said the partnership reflects shared roots and global reach.
He said the company was “pleased to become the first jersey-patch sponsor of the Chicago White Sox” and pointed to both organizations’ connections to Chicago and international audiences.
As part of the White Sox deal, the CME Group logo will appear on the team’s home, road, and alternate uniforms, including the MLB Nike City Connect jersey. The patch will be worn during Spring Training, the regular season, and postseason games.
CME Expands Sports Marketing Presence
CME Group will also receive fixed signage behind home plate at Rate Field during home games, along with other promotional placements.
White Sox Chief Revenue and Marketing Officer Brooks Boyer said the team sought a Chicago-based partner whose brand would be visible on the uniform. He described CME Group as having a global footprint and said the partnership extends beyond branding.
White Sox Reveal Jerseys Featuring CME Patch
The jersey patch design will vary by uniform. On the home pinstripes, the blue CME Group logo will appear on a white background with a black border and black lettering. The road gray uniform will feature the blue logo on a gray background with black lettering. The City Connect and alternate black jerseys will display the blue logo on a black background with white lettering.
The White Sox will debut the updated uniform during Cactus League play against the Chicago Cubs. The jersey patch will then appear in the 2026 regular season opener in Milwaukee, followed by the home debut at Rate Field against the Toronto Blue Jays.
