NFL Pushes Kalshi and Polymarket to Drop NFL Bets
The league formally letters prediction market operators as MLB and NHL take the opposite approach.
The NFL sent a formal letter this week to prediction market operators — including Kalshi and Polymarket — demanding removal of certain NFL-related bet types, cementing its position as the most resistant major US sports league to the prediction market sector.
Why It Matters
As of September 2026, the NFL generates more US sports betting handle than any other league, making its stance on prediction markets commercially decisive. While MLB and the NHL have moved in the opposite direction — signing leaguewide partnership deals with prediction market platforms — the NFL's formal written opposition signals a potential regulatory and legal flashpoint heading into the 2026 season. Operators who ignore the letter risk league-backed pressure on regulators, which could influence how the CFTC classifies sports-event contracts. For bettors who use Kalshi, Polymarket, or similar platforms to trade NFL outcomes, the product availability could narrow quickly. The divergence between leagues also fragments the prediction market landscape in a way that complicates operator strategy.
Context
Prediction markets occupy a legally ambiguous space in the US: platforms regulated by the CFTC argue their event contracts are distinct from traditional sports betting, while leagues like the NFL contend they function as unlicensed gambling products. Per SBC Americas, the NFL has now reiterated its concerns in writing directly to operators, escalating beyond informal lobbying. MLB and the NHL's partnership approach shows the sector is not uniformly opposed by professional sports — the NFL is the outlier, not the norm.
What's Next
Watch for operator responses from Kalshi and Polymarket in the coming days, and monitor whether the CFTC issues any guidance prompted by the NFL's letter before the regular season kicks off. A formal league complaint or legal filing would be the next significant escalation.
Gambling involves financial risk. Prediction market contracts can lose value rapidly.
