California
Generally available
Why this is the answer

Federal standing sits above state lines.

Polymarket operates under United States oversight at the federal level. A federally regulated market does not need a separate California licence to offer its core event contracts, which is why it can be available to California residents even where state gambling rules are strict. The live friction is mostly around sports-event contracts, where some states have pushed back.

The short version

Polymarket is a US venue, so its availability in California generally turns on federal standing rather than a California state licence, subject to your age and identity verification. Some products, sports-event contracts in particular, have faced state by state friction, so confirm the current position before you act.

FAQ

Polymarket in California, in short.

Is Polymarket legal in California?

As of February 2026, Polymarket is generally available to verified California residents. It returned to the United States in December 2025 through a designated contract market and clearinghouse overseen by the Commodity Futures Trading Commission, so access does not turn on a separate California gambling licence. You still need to be of legal age and pass identity checks. This is general information, not legal advice.

Did Polymarket leave the United States?

Yes. After a 2022 settlement with the Commodity Futures Trading Commission, Polymarket stopped serving United States customers for roughly four years. It returned to the United States in December 2025 through a federally regulated designated contract market and clearinghouse and dropped its United States waitlist in May 2026.

Are Polymarket sports event contracts legal in California?

This is contested. Sports event contracts face state challenges across the category, including tribal litigation in California, and at least one state ordered prediction market platforms to halt sports offerings in early 2026. The position is still moving, so treat it as contested and confirm the current rules before relying on it.

What do I need to open an account from California?

An available platform will ask you to confirm your age, verify your identity, and fund the account on its own website. Always check the current eligibility rules directly with the platform before you act.
