Why isn't this the same as sports betting?

Sports betting is regulated at the state level under gambling law. Prediction markets are regulated federally by the CFTC as event contracts, which are financial instruments. Different product, different regulator, different legal framework.

Did California legalize online sports betting?

No. Propositions 26 and 27 both failed in November 2022. California has no legal online sports betting, and there is no active legislative effort to change that.

Can I use Kalshi from California?

Yes. Kalshi is a CFTC-regulated Designated Contract Market available in all 50 US states, including California. Sign up takes under ten minutes.

Can I use Polymarket from California?

Polymarket is relaunching for US traders through its acquisition of a CFTC-licensed exchange. As the US product rolls out, it is legally available to California residents under federal commodities law.

What can I trade from California?

Sports outcomes (including all World Cup 2026 markets), election results, economic data, Oscars and Emmys, crypto price targets, and more. Event contract coverage is broader than a traditional sportsbook.

Is this going to stay legal?

The federal legal framework is settled enough that the major platforms operate openly today. Ongoing state-level challenges and future Supreme Court review could narrow the scope of sports contracts specifically, but a total shutdown of prediction markets is highly unlikely. Non-sports markets face minimal legal risk.

Do I pay California state tax on winnings?

Yes. Gains from event contracts are taxable as ordinary income or capital gains depending on holding period and classification. Keep records and consult a tax professional for your specific situation.

What's the minimum age?

21+ across platforms. Each platform's exact age requirement is listed at sign-up.

Are offshore sportsbooks legal in California?

No. Offshore sportsbooks operate outside US regulatory oversight and are not a legal option for California residents. CFTC-regulated prediction markets are the legal alternative.
