The NBA Is Partnering With Prediction Markets to Protect the Integrity of the Game
The NBA announced partnerships with Polymarket and Kalshi, saying access to trading data and control over which markets are offered will help it spot suspicious betting action.
A headline that sounds like a joke
Morning Brew calls its own headline Onion like, and then confirms it is real. The NBA announced partnerships with Polymarket and Kalshi, the two best known prediction market platforms, and framed the deals as part of a push to protect the integrity of the game.
The timing explains the move. Since 2024, the league has dealt with wagering scandals that included a player receiving a lifetime ban and federal investigations involving organized crime figures, as Morning Brew recounts. A league that cannot credibly police betting on its own games has a product problem, not just a legal one.
What the league gets in the deal
The partnership gives the NBA two concrete tools. First, the league will have access to trading data from Polymarket and Kalshi, which can help it locate suspicious action early instead of learning about it from an indictment. Unusual money moving against a little watched market is a signal, and signals are only useful if someone is watching them.
Second, the league gets a say in what can be bet on at all. Morning Brew reports that the NBA will have final say on which markets are offered. Some categories are off the table entirely under the deal.
The bets that are now banned
The restrictions target the easiest bets to manipulate. Users will not be allowed to wager on single plays, such as the first basket or the opening tip. One player deciding one moment is exactly the kind of event a corrupt actor can buy cheaply.
Bets are also barred on unders for players expected to play fewer than 12 minutes. A bench player who knows his own minutes can move that market with information nobody else has. Removing the most fixable markets does not end betting on the NBA. It removes the bets where one quiet conversation can decide the outcome.
A wider web of agreements
The prediction market deals do not stand alone. Morning Brew reports that the NBA is expanding its existing agreement with DraftKings and other sports betting partners to include prediction markets. The league also reached a cooperation agreement with the Commodity Futures Trading Commission, the federal regulator that oversees prediction markets.
Read together, the pattern is a league building a perimeter. Every major place where money moves on its games is being brought inside a relationship where the league can see data, set limits, and call a regulator who already has a seat at the table.
The legal fight is not settled
None of this ends the argument over what prediction markets legally are. State regulators argue that these platforms are sports betting dressed in the language of federally regulated commodities trading, built to avoid state gambling rules, as Morning Brew summarizes their position.
The Supreme Court has agreed to consider whether states can ban prediction markets. That ruling will decide whether the NBA new partners operate under one federal framework or fifty state ones. The league has placed its integrity strategy on platforms whose legal ground is still being argued at the highest court.
The lesson for anyone running live events
Strip away the betting and the structure of this deal is familiar to anyone who runs events for a living. When money moves around your product in places you cannot see, your choices are to ignore it, fight it, or bring it inside with data access and rules you helped write.
The NBA chose the third option, publicly, after scandals forced the question. Organizers and promoters face smaller versions of the same choice with resale tickets, unofficial streams, and unapproved vendors. Seeing the activity early and setting the terms beats discovering it after the damage is photographed and posted.
