Who Are CME Group’s Top Shareholders?

Hedge Fund Highlights
One notable move last quarter came from Balyasny Asset Management, founded by Dmitry Balyasny, which sharply increased its exposure to CME Group. The position grew by a large percentage to a meaningful dollar value, which appears to reflect a more constructive view on CME Group’s long-term earnings durability.
Another standout was Hudson Bay Capital Management, led by Sander Gerber, which boosted its CME Group stake by over 3,000% to roughly $9M value. While the position remains small in absolute terms, the scale of the increase stands out following recent share price consolidation.
Horizon Kinetics Asset Management, founded by Murray Stahl, also raised its CME Group holdings by more than 100%, bringing its position to roughly $75M value, which may suggest confidence in the company’s asset-light structure and cash flow consistency.
Meanwhile, Gotham Asset Management, run by Joel Greenblatt, increased its CME Group position by about 41% to approximately $47M value, a move that appears consistent with Gotham’s valuation-focused approach, and for investors highlights selective accumulation rather than broad hedge fund consensus.
Taken together, hedge fund activity around CME Group appears selective rather than one-sided. Several managers meaningfully increased exposure, while others remained on the sidelines, which for investors suggests growing interest in CME Group’s earnings durability and cash flow profile, but not a broad shift toward aggressive positioning at current price levels.
