The NBA has told its authorized sportsbook partners to remove or limit several wager types it considers especially vulnerable to manipulation. The restrictions arrive at the start of the 2026-27 season and concentrate on markets that can be decided by a narrow action or a player's limited participation.
According to ESPN's report on the league memo, bettors will not be able to combine multiple unders on the same player's statistics in one parlay at partner books. The changes also cover opening-tip outcomes and other first-event bets, propositions on a specific missed shot, unders for players expected to appear for fewer than 12 minutes, and alternate unders offering a larger payout.
The Associated Press independently reported that the NBA confirmed the policy. The action is narrower than a nationwide regulatory ban because the league is directing its commercial betting partners. Markets offered by unaffiliated operators depend on their own rules and the law in each jurisdiction.
The policy targets bets whose outcome may turn on a single controllable moment or a very short appearance. Limiting those markets reduces the potential value of inside information and makes it harder to build high-payout combinations around deliberate underperformance. It does not eliminate integrity risk, so monitoring, operator controls and timely team information remain important.
The league's official injury-report page continues to require teams to disclose player availability before games and update statuses when circumstances change. That reporting framework is separate from the new sportsbook restrictions, but both measures address information gaps around player participation.
The feed item also referred to draft changes. The confirmed betting-policy event is the new partner restriction described by ESPN and AP; no separate draft claim is relied on here. The practical test will be whether partner books remove the affected markets consistently and whether suspicious betting can still migrate to unaffiliated platforms.
