Indian Gaming Association joins AGA in opposition to prediction markets

The Indian Gaming Association's Jason Giles did not come to Las Vegas this week to observe. He came to draw a line, and the language he used was not ambiguous: prediction markets represent an existential threat to the regulated US gaming market that tribal operators have spent decades building.

That framing matters, because the IGA's entry into this fight changes its character. Bill Miller and the American Gaming Association have been visible opponents since prediction markets began expanding into states with active sports betting regimes, and their arguments have been well-documented. But the tribes bring something different to the coalition. They hold state compacts. They operate under a federal framework that predates modern online gaming. And in California — where prediction market growth has been particularly sharp — they are, as California Nations Indian Gaming Association Chair James Siva noted at the G2E panel, the only licensed operator in the state.

California is the number that concentrates the mind. Siva's comment was brief, but its implication runs deep. A prediction market that operates freely in California without triggering the state's gambling statutes is not competing with tribal casinos at the margin — it is occupying space that the compacts were written to protect. Whether federal preemption arguments can survive that challenge is a question several courts have now begun to answer, and the answers have not been kind to prediction market platforms.

The Sixth Circuit's ruling in Tennessee's favour arrived just before G2E opened. That decision, reversing a lower court that had sided with Kalshi, gave the states a second consecutive circuit win. Miller's public assessment — that the Supreme Court is the likely endpoint — carries more weight after two losses at the appellate level than it would have after one.

The CFTC's response has been to keep moving on rulemaking rather than wait for judicial resolution. Two proposals sent to the White House Office of Information and Regulatory Affairs this week would reshape the regulatory boundary: one broadening the definition of a swap to include event contracts, another potentially carving out gaming-style products from that definition entirely. The practical effect, if both survive review and implementation, would be to preserve federal jurisdiction over financial event contracts while denying DCMs the ability to list blackjack or craps equivalents — a concession to the casino industry that costs the CFTC little and buys some goodwill during a period of intense jurisdictional pressure.

The AGA's estimate that states have lost more than a billion dollars in tax revenue from prediction market growth is the number that will drive legislative behaviour in 2027. Billion-dollar revenue gaps produce bills. Combined with an IGA that now views the sector as an existential opponent rather than a nuisance, the political coalition assembling against prediction market platforms is broader and more durable than it was twelve months ago.

My read is that the consensus underweights how much the tribal dimension reshapes the political economy of this fight. Commercial casino operators have financial interests. Tribes have sovereign ones. Federal legislators who might accommodate CFTC preemption arguments in a dispute between two commercial industries face a different calculation when tribal compacts are explicitly at stake. That is not a legal argument — it is a count of votes, and the tribes have always known how to count them.
