Is Polymarket legal in your state?

As of Oct 16, 2026, no state has switched Polymarket off entirely. Courts have switched off some of its markets in Nevada. In 7 more states a lawsuit, ruling or cease-and-desist is live, but nothing is switched off.

Every state, dated.

Every state sits in one of four groups. Select a state for what is switched off there and the order behind it.

Every state action here names QCX LLC, the exchange that trades as Polymarket US and that the CFTC designated a contract market in July 2025. Several also name its parent, Blockratize. The international site, polymarket.com, is a separate product and lists the whole US as close-only: people in the US can close positions on the international site but not open new ones.

What states have sued Polymarket?

As of Oct 16, 2026, five states and the City of Baltimore have taken Polymarket US to court, and Polymarket US has sued two states itself. Only an order in force switches anything off, and Nevada’s is the only one we have found.

  1. 01A state or city sues Polymarket USAn attorney general, a gaming regulator or, in Baltimore, the city goes to state court. Nevada’s is the case that produced an order now in force.
  2. 02Polymarket US sues firstPolymarket US asks a federal court to stop a state’s officials enforcing state law against it, as it did in Michigan and Minnesota.
  3. 03The case changes courtPolymarket moved each state-court suit to federal court. Nevada’s was sent back; several wait on a ruling about which court hears them. A move switches nothing off.

Where Polymarket went to court first

StateCaseDocket
MichiganQCX LLC v. NesselU.S. District Court, W.D. Mich., No. 1:26-cv-00710Docket
MinnesotaQCX LLC v. EllisonU.S. District Court, D. Minn., No. 0:26-cv-02841Docket
Polymarket asking a federal court to stop a state enforcing its gambling law. These cases switch nothing off.

Two of these cases run alongside Kalshi’s. In Minnesota, the preliminary injunction covers suits by Polymarket US, Kalshi and the CFTC together. In Rhode Island, the state’s case against Polymarket US was combined with Kalshi’s own suit against the state’s regulators.

Courts

Where the courts stand.

Whether federal commodities law preempts state gambling law is unresolved. Each federal appeals court with a Polymarket case, and the Supreme Court dates ahead.

Ninth CircuitAK, AZ, CA, HI, ID, MT, NV, OR, WANo decision yetPolymarket's appeal of the order sending Nevada's case back to state court (No. 26-1343) is on hold behind three other Nevada appeals, Kalshi's among them.

Federal appeals courts that have a Polymarket case. A ruling binds the federal courts in the states it covers.

At the Supreme Court

Who gets to regulate sports contracts on a federally registered exchange: only the federal regulator, or the states too? The Court is being asked whether federal commodities law preempts state gambling laws, not whether anyone must stop, and not how the trades are taxed.

Dates ahead

  • Nov 9, 2026 Kalshi's response to New Jersey's petition is due. Docket

  • Nov 16, 2026 Nevada's response to Crypto.com's petition is due. After briefing, the justices decide whether to take any of the three. Docket

A state court order about gaming licensing isn't a ruling on how trades are taxed. There is no IRS guidance on event contracts. Polymarket is not a party to any of the petitions; Kalshi at the Supreme Court follows them.
