The legal position in Washington
Washington is a notable case: it permits sports betting only in person at tribal casinos, has no legal statewide mobile sportsbooks, and has historically treated some forms of online wagering with unusual severity. We are not aware of a specific cease-and-desist or lawsuit aimed at prediction markets in Washington as of mid-2026, and the leading CFTC-regulated platforms advertise availability — but the state’s strict gambling climate is a reason to check eligibility more carefully here than in a permissive state.
Prediction-market event contracts are federally regulated derivatives, which is the basis on which the platforms operate; whether that fully insulates them from Washington’s strict regime is the sort of question the national preemption fight will influence. See US legality.
Which platforms operate in Washington
The major platforms generally serve Washington, but given the state’s strict gambling laws you should treat the platform’s own eligibility screen as the decisive check before funding — and never attempt to evade any block, which violates platform terms.
We are not aware of a specific state block as of June 2026, but this landscape changes quickly and this page is general information, not legal advice. The platform’s own eligibility check at sign-up is always the authoritative source for your address.
Sources: public reporting on the 2026 federal-versus-state prediction-market litigation. Availability and legal status change frequently; verify the current position with the platform and, for legal questions, a qualified professional. Nothing here is legal advice.

Frequently asked questions
Can I use prediction markets in Washington State?
Generally yes as of mid-2026 — we are not aware of a specific state action against the platforms, and they advertise availability. But Washington has unusually strict gambling laws and only allows in-person tribal sports betting, so check the platform's own eligibility screen carefully before funding.
Why does Washington need extra caution?
Washington permits sports betting only in person at tribal casinos, has no legal statewide mobile sportsbooks, and has historically treated online wagering strictly. While prediction markets are federally regulated derivatives, the strict state climate makes verifying eligibility with the platform especially important.
