Kalshi admits handling billions in illegal sports betting contracts

Kalshi told a federal court sports betting was illegal and has since handled 190 billion dollars in sports contracts tax-free

Bill Miller said it from the main stage at The Venetian on Tuesday, and the room went quiet in the way rooms go quiet when someone finally says the number out loud.

The American Gaming Association's president and CEO was addressing the Global Gaming Expo crowd — casino executives, regulators, lobbyists, the people who have spent decades building a licensed, taxed, scrutinized industry — and he chose to open with the contradiction that the prediction market sector has never cleanly answered. Kalshi's own CEO, Tarek Monsour, argued in federal court that offering sports bets at the federal level would be illegal. That was less than two years ago. Miller's point was not subtle: the company then went and processed what he says is $190 billion in sports contracts, paying nothing in state taxes.

That number is doing a lot of work in this fight. The licensed gaming industry runs on tax revenue — it is, structurally, the argument for tolerating casinos at all. States collect, tribes compact, regulators audit. Prediction markets have routed around every part of that architecture by persuading the CFTC that what they sell is a derivative, not a bet, and that federal jurisdiction is exclusive. The CFTC has not exactly resisted this framing. The agency sent two new rulemakings to the White House for review this week: one that would formally classify event contracts as swaps under the Commodity Exchange Act, and a second that would carve casino-style gambling products out of that same definition. The casino industry reads that pair of rules exactly as it looks — the CFTC drawing a box around prediction markets to protect them from state oversight, and drawing a second box around casino products to make sure the first box doesn't accidentally shelter anything the agency doesn't want to cover.

Miller's language at G2E was not the language of a trade association managing a policy dispute. He called prediction market operators "well-funded bad guys" who kicked in the back door. He said their message to states and tribes is that their laws, regulations, tax structures, and sovereignty don't matter. For a sector that has spent years cultivating a reputation for measured public positioning, that is a signal of how the licensed industry now reads its situation — not as a competitive threat to be absorbed, but as an existential one to be defeated in court.

The courts have not cooperated with a clean answer. Ohio and Tennessee have pursued litigation arguing that sports event contracts violate state gambling law. New York sued Polymarket the week of G2E with the aim of banning the platform outright. New Jersey's attorney general has asked the Supreme Court to resolve a circuit split that lower courts have been unable to close. The CFTC's rulemaking push is partly a move to get federal definitions locked in before any court can constrain them.

I've watched regulatory agencies use interim final rules to accelerate line-drawing before, and it rarely settles the underlying dispute — it tends to harden the parties on either side of the line instead. The CFTC classifying event contracts as swaps doesn't make the states drop their lawsuits. It gives prediction market platforms a stronger federal preemption argument the next time a state comes after them. Whether that argument survives Supreme Court review is the open question that neither the CFTC's rulemaking nor Miller's speech at G2E can answer.
