Kalshi and Polymarket face bans in more than a dozen states

A map of the United States showing which states permit sports prediction markets and which prohibit them is, at this moment, less a regulatory chart than a legal argument in progress. CBS Sports has compiled the current status across all fifty states, and the picture it produces is not the orderly patchwork of a settled federal system — it is the outline of a fight that has not yet been resolved.

More than a dozen states have moved to block Kalshi and Polymarket from operating within their borders. The mechanism varies. Some states treat the contracts as sports betting requiring a state licence. Others lean on existing gambling statutes whose language was never written with prediction markets in mind but stretches to cover them under a sufficiently hostile reading. The result is that a person in one state can open an account and trade a contract on the Stanley Cup winner, while someone two states over faces a platform that will not load.

The legal theory Kalshi has used to resist this — that CFTC authorisation pre-empts state law — has not settled the argument. It has deepened it. States are not waiting for a definitive federal ruling before acting, and the volume of state-level challenges accumulating in courts right now suggests that the pre-emption question will not be resolved by a single clean decision. It will be resolved by attrition, or by the Supreme Court, or both.

What the CBS Sports map does not show, but what follows from looking at it carefully, is that the states blocking access are not clustered by geography or party in any simple way. The pattern is closer to institutional reflex — gaming regulators protecting a licencing framework that generates revenue and accountability, and treating federal pre-emption as a threat to both rather than a clarification. Nevada's posture, which this newsroom has covered at length, is the clearest version of this, but it is not the only version.

My read is that the consensus framing — that federal authority will eventually wash over state resistance and sports prediction markets will open nationally — is moving faster than the legal ground supports. The state-level opposition is not symbolic. It is procedurally durable, it is backed by regulators with real enforcement capability, and the pre-emption argument that Kalshi is running has not yet won in a circuit that matters to the states most aggressively pushing back.

I have been wrong about regulatory timelines before, and expensively so. What I learned from that experience is that the institutions doing the resisting always have more runway than the people predicting their defeat allow for. The states blocking these contracts have licencing frameworks, tax flows, and tribal compacts tied to the current structure. They are not going to fold on a legal theory that is still being litigated.
