NBA strikes prediction-market deals with Kalshi and Polymarket, with integrity rules and CFTC oversight in focus

The NBA has agreed deals that make Kalshi and Polymarket the league’s preferred prediction markets, alongside an agreement with the federal agency that regulates those exchanges. For payment and gambling operators, the detail that matters is not the branding; it is the league putting hard limits around market types, information sharing, and who inside the NBA can trade on its games.

1. The agreements, announced on Monday, are designed to provide “significant integrity protections for markets related to the NBA.” That includes limits on what can be offered on those exchanges, transparency around suspicious user patterns, and a ban on league and team personnel trading on events tied to the league.
2. The prediction markets will have “information-sharing obligations related to investigations and suspicious trading,” according to the NBA. The league said it has long had similar safeguards with its sports betting partners and has pointed to cases where that system identified irregular betting patterns.
3. Scott Kaufman-Ross, the NBA’s head of media distribution and partnerships, said regulation is the key difference: “If you’re going to bet on our games or trade on our games or play fantasy around our games, it’s better that it’s regulated and not unregulated.” He added that the league is in a better position to protect game integrity in a regulated market where there is transparency and visibility into what is happening.
4. The NBA is also expanding its existing official sports betting partnerships, including DraftKings, to cover their prediction-market offerings. That matters because not all states allow legalized sports betting, while prediction markets — at least at some level — are available in essentially all 50 states.
5. Regulatory fights are already attached to the segment. More than a dozen states are involved in litigation over prediction markets, and earlier this month the NFL asked the U.S. Supreme Court to weigh in on how those markets should be regulated. The Commodity Futures Trading Commission says it has exclusive jurisdiction over oversight, while some states argue the matter should fall under their own authority.

The NBA also told sportsbooks earlier this month that certain bet types will not be allowed this season, including first-stat props, the outcome of the opening tip, and “under” bets on players not expected to play more than a few minutes. The league said the Monday deals are expected to carry similar restrictions. For high-risk operators, that is the real headline: access to NBA-related markets is being paired with explicit product constraints, and the league wants approval rights over what can appear on its games.
