Dreitzer draws line at Supreme Court as tribal allies weigh defection

The question Scott Crowell said tribes were asking at G2E was direct: what happens if we lose? Mike Dreitzer, chairman of the Nevada Gaming Control Board, had a direct answer. There is no plan B.

That exchange, during an Indian Gaming Association webinar on Wednesday, carried more weight than the usual regulatory sparring because of what surrounds it. Kalshi has a favorable ruling out of the Third Circuit. It holds a preliminary injunction in Illinois. The Sixth and Ninth Circuits went the other way, which is why the Supreme Court is the destination everyone in the room was already thinking about, even if Dreitzer refused to plan for the outcome.

His argument against prediction markets has not changed, but he sharpened one edge of it this week. When the CFTC issued two proposals — one expanding the swap definition to cover sports, politics, and cultural events, the other confirming that casino-style gambling falls outside that definition — Dreitzer's response was not alarm. It was recognition. He called it the next step by an agency working, in his words, in lockstep with the designated contract markets. The surprise would have been if they hadn't moved.

The substantive objection is that the CFTC's distinction between a ten-dollar sportsbook wager and a ten-dollar sports-event contract describes the same transaction twice. Dreitzer has made this argument before. What he added Wednesday was a closer look at the peer-to-peer claim — the assertion that prediction markets are different because traders face each other, not a house. His counter was that poker, horse racing, and bingo are all peer-to-peer. None of them escape gambling law on that basis. He also raised something the peer-to-peer framing tends to obscure: hedge funds and affiliated trading entities sit on the other side of many retail prediction market trades. The image of two casual traders pricing an election outcome against each other is not always what the order book shows.

The harder problem for Dreitzer's side is the defection he is watching happen in real time. Some tribes, which have historically aligned with state regulators against prediction markets, have begun partnering with Kalshi. One tribe in a recent announcement disputed the characterization of their arrangement, which may say more about the political difficulty of the position than about the underlying decision. IGA Executive Director Jason Giles acknowledged the anxiety directly — tribes at G2E were asking whether standing firm had already cost them ground they cannot recover.

Dreitzer said he felt for them. That is a different register than his usual tone, and it signals something. The coalition holding the state-regulator position is under internal pressure that procedural wins alone cannot relieve. Kalshi is operating in jurisdictions where sports betting is not legal, accepting users from the age of eighteen, and — by Dreitzer's characterization — doing so as a matter of open policy rather than legal ambiguity. His word for it was crime. The regulated industry's unified front, with MGM and Caesars holding their casino licenses back from the space while FanDuel and DraftKings have not, is the only structural leverage states currently have before the Supreme Court takes the question.

If the court sides with prediction markets, Dreitzer has no answer prepared. That is a position, not an oversight — it is the only position available to a regulator who believes the law is unambiguous. The market for that outcome is open. The states have won more rulings than they have lost, but the ones Kalshi has won are in circuits that matter, and the Supreme Court does not take a case to affirm a circuit split.
