Is it legal to bet on the 2026 World Cup in California?

Traditional sportsbooks are not legal in California — voters rejected legalization in 2022 and no law has passed since. CFTC-regulated event contracts on platforms like Kalshi and Polymarket are legal under federal commodities law, which preempts state-level sports-betting prohibitions for these contracts.

What's the difference between a sportsbook bet and a prediction market contract?

A sportsbook sets a line and takes the other side of your bet, profiting from the vig (typically 4.5–5%). A prediction market is a two-sided exchange where you buy and sell contracts against other traders for a fraction of a cent in fees. You can also sell early on a prediction market — no need to hold to resolution.

Which platform should I open first for the World Cup?

Kalshi for first-timers — bank-account funding, 1099-B tax forms, deep USMNT and outright contracts, 10-minute KYC. Polymarket as the second account for the deeper global outright market and cross-platform spreads (settles in USDC, requires a crypto on-ramp).

How much should I deposit for my first World Cup contract?

$25 is the right starting size. Enough to make a real trade and learn the mechanics; not enough to bury you if you mis-click. Add more once you're comfortable with the interface and the way contracts settle.

Can I use a VPN to access DraftKings or FanDuel from California?

No. Using a VPN to evade geofencing violates terms of service, voids any winnings, and can void the account permanently. There is no legal workaround that gets a California resident a US sportsbook account — use the platforms that are actually legal here.

What about offshore sportsbooks like Bovada?

Don't. Offshore books are illegal under federal law to operate in the US, your deposits aren't protected, and the operators have no obligation to ever pay you out. CFTC-regulated venues exist specifically so US residents have a legal, supervised alternative.

How are tournament odds currently priced?

Spain and France are co-favorites at roughly 17–18% each on Polymarket. England trades around 11%, Brazil and Argentina around 8–9%, and the USMNT around 1.5% on the outright winner contract. Prices update daily on the live odds widget on our World Cup hub.

Do I have to pay taxes on World Cup winnings in California?

Yes. Kalshi issues a 1099-B that gets reported to the IRS and the California Franchise Tax Board automatically. Polymarket does not issue 1099s — California residents must self-report on Schedule 1 or Schedule D. Both platforms' gains are subject to California state income tax.
