NFL markets drove the biggest individual trading totals
Individual NFL games generated more than $700 million in Week 3 volume, slightly above the $695.4 million reported the previous Sunday.
The Rams-Broncos game led all individual NFL matchups with $152.3 million in trading volume. Other top games included Ravens-Cowboys at $77.4 million and Seahawks-Commanders at $64.2 million. Covers also reported that Chargers-Bills and Chiefs-Dolphins each topped $50 million.
Kalshi reportedly handled about 85% of the Rams-Broncos total and at least 50% of volume in eight of 13 other NFL games tracked in the report.
College football and soccer added to the weekend total
Saturday’s college football slate helped lift overall weekend notional trading by 2.7% week over week. Combo plays rose from $2.30 billion on Sept. 19 to $2.51 billion on Sept. 26.
No single NCAA game reached $100 million, but college football game volume still increased 14.4% from the previous week. Ole Miss-Florida led that group at nearly $87 million, followed by Northwestern-Indiana at $76.6 million, Texas-Tennessee at $73.2 million, and Clemson-Cal at $71.3 million.
Outside U.S. football, the UEFA Nations League match between England and Spain generated $28.4 million in trading volume.
