The NBA is finalising sponsorship agreements with prediction-market operators and expects to announce them before the 2026-27 season begins, according to reports published on 3 September. Deal terms are on the table after more than a year of negotiation with Kalshi, Polymarket, Novig, Fanatics and Rothera, the joint venture between Robinhood and Susquehanna.
The benchmark is Major League Baseballs exclusive agreement with Polymarket, valued at US$300m over four years. The NBA is structuring its market differently, intending to sign multiple partners on tiered rights packages rather than sell exclusivity to one platform. A source involved described the design plainly: Not all will necessarily have the same set of rights. A prediction-market executive told Front Office Sports that my guess is the number is going to be bigger than MLB. Team-level deals already exist across the New York market, with the Yankees and Rangers partnered with Polymarket and the Mets with Novig. The NFL has taken the opposite position, declining prediction-market sponsorship for 2026 and naming DraftKings, FanDuel and Fanatics as its official sportsbooks in late August.
Choosing non-exclusivity over a single-partner premium is the decision worth reading closely. Exclusivity extracts the higher headline fee, which is why MLBs deal is the number everyone cites, but it concentrates counterparty risk in a category whose legal status remains unresolved. The Ninth Circuit ruled on 28 August that federal law does not preempt state gambling regulation, creating a split with the Third Circuit; New Jersey filed a 332-page certiorari petition on 2 September, Robinhood and Crypto.com followed on 9 September, and 19 states remain in active litigation. Robinhood has already agreed to stop offering sports event contracts in Michigan, and courts in Iowa and the Tenth Circuit ruled against Kalshi in the same week. Spreading rights across several operators means no single adverse ruling removes the leagues revenue from the category.
The commercial case for moving now is visible in the volume. Prediction markets traded at least US$1.034bn on NFL Week 1 alone, up more than 1,280 per cent week-on-week, with Kalshi accounting for US$983.18m of it and a single game, 49ers-Rams, drawing US$117.69m. That is a revenue pool that did not exist 24 months ago, growing faster than the regulated sportsbook market it competes with, and the NFL currently monetises none of it. Whatever number the NBA announces will become the clearing price for the category and the reference every other league, federation and team uses when it negotiates. It will also be the most consequential test yet of whether a major American league can underwrite a sponsorship category while the Supreme Court decides who is entitled to regulate it.
