NBA names Kalshi and Polymarket preferred prediction-market exchanges
The National Basketball Association designated Kalshi and Polymarket as its preferred prediction-market exchanges. The league is licensing its brand to the two platforms, which are CFTC-regulated. NBA officials said the partnerships are designed to give the league more control over what people can bet on regarding basketball events. Experts warn the agreement could affect fan engagement and pose reputational risks. The article does not specify deal terms.
The NBA deal fractures what had been unified league opposition to prediction markets. The NFL now stands alone among major U.S. sports leagues in resisting the sector, weakening a central argument state attorneys general use to push gambling classification. Kalshi and Polymarket, the partnerships bring official data and marketing legitimacy that most platforms cannot match.
The integrity restrictions set a template other leagues may copy. Each NBA or MLB arrangement the NFL lacks becomes ammunition in federal and state court fights over whether event contracts are disguised gambling. The NFL's legal strategy carries heavier commercial risk now because it has no cooperative framework to fall back on if courts reject its position.
