NBA Commissioner Adam Silver raises sports data rights as prediction market fight widens

Adam Silver was in Macau for an exhibition game when he told CNBC that prediction markets create two distinct problems for professional sports leagues: integrity risk and a data question the industry has not yet answered.

The data question is the one that gets underweighted. Most of the coverage around Flaherty v. KalshiEx has focused on the jurisdictional fight — whether the CFTC or the states govern event contracts — and on the NFL's 32-page amicus brief co-authored by former Attorney General William Barr. The NFL's objections are well-documented at this point: field goal miss contracts, next-penalty markets, prop bets on phrases spoken during broadcasts. The league argues the CFTC lacks the oversight capacity to police these without threatening game integrity, and 39 states plus the District of Columbia have lined up behind New Jersey's petition asking the Supreme Court to hear the case.

But Silver's comment points at something structurally different. When he raises data rights alongside integrity, he is not just echoing the NFL's brief. He is identifying the commercial position the leagues have not yet formalized in this litigation: if prediction markets are derivatives regulated by the CFTC, the leagues lose their strongest argument for extracting data licensing fees. The moment a kicker's field goal attempt becomes a federally regulated financial instrument, the underlying event — the kick itself — starts to look like a commodity input, not proprietary content.

I want to be honest about my own tendency here. I find the structural downside before I find the upside, and Eleanor has been right to flag this. So let me say plainly: the CFTC's interim rule separating casino-style gambling from event contracts is probably the more durable near-term development. Selig has moved faster than most regulators move, and the interim rule's immediate effective date upon Federal Register publication is not nothing. Regulatory momentum of that kind is hard to reverse even when a court intervenes.

Still, the data question Silver raised in Macau does not go away under CFTC jurisdiction — it gets harder. At least under state gambling frameworks, leagues have existing compact structures and statutory hooks for integrity fees. Federal derivatives regulation offers them nothing equivalent. Kalshi says it tried to work constructively with the NFL. The NFL says the opposite. I have seen enough counterparty disputes to know that when both sides claim to have acted in good faith and negotiations failed anyway, the gap is usually about money, not process.

What Barr's brief actually does is give the Supreme Court a clean doctrinal hook: are these instruments more like swaps, or more like wagers? That binary has never been formally resolved at the highest level. The circuit split between the Third and Ninth Districts is real, and the court takes those seriously. Whether the current bench, with four seats shaped by administrations with very different views on federal regulatory reach, resolves this in Selig's favor is not a question anyone should answer with confidence.
