What is Polymarket?

Polymarket is a prediction market where users trade Yes/No event contracts on politics, news, sports, crypto, and culture. Contracts settle at $1 if the event resolves Yes and $0 if No, so the price reflects the live implied probability set by the order book.

Markets and coverage

Politics and news are Polymarket's bread and butter — elections, geopolitics, Fed decisions, corporate earnings calls, awards shows, and cultural events. Sports coverage has expanded rapidly through 2025–2026, and crypto-native markets remain among the sharpest anywhere.

Liquidity and pricing

On flagship politics and macro markets, Polymarket often has strong liquidity and tight spreads. Check the live order book before you trade. This is the standout reason serious traders keep an account funded.

User experience

The Polymarket app is fast, modern and arguably the cleanest mobile UX in the category. Order book depth, charts and portfolio P&L are all one tap away, and contract resolution is transparent.

California availability

Polymarket is available to verified California residents. Onboarding, deposits, and trading work from any CA county with no geofencing issues in our testing.

Welcome bonus

Deposit $10 and trade qualifying event contracts to unlock a $25 trading bonus — one of the most generous straightforward welcome offers in the prediction market space right now.

Who Polymarket is best for

Politics traders, macro and news traders, and anyone who wants the deepest global liquidity on event contracts. Pair it with Kalshi for the strongest two-app US setup.

State availability

Californians (Polymarket's minimum age is 18; we recommend 21+) can open Polymarket and use code VENICE. Outside California, it isn't offered in Nevada.

How we tested

Catie opened and funded an account on Polymarket US with her own money (about $200), placed real trades and withdrew. The screenshots on this page are from that account.

Editor's note

I funded and tested Polymarket personally before writing this review: no free press access, no operator-supplied account. My background is 15 years in regulated iGaming, including running the Hard Rock New Jersey online CRM launch under a DGE vendor license, so I hold prediction market operators to a real regulated-operator standard.

Frequently asked questions

Is Polymarket available in California?

Yes. Polymarket is available to verified California residents and operates with full functionality in all CA counties.

How does the $25 bonus work?

Deposit at least $10 and trade qualifying event contracts to unlock $25 in trading credit. See in-app terms for the active promo period.

How is Polymarket different from Kalshi?

Polymarket has the deepest global liquidity, especially on politics, news and culture markets, and a slicker mobile UX. Kalshi has the broadest US-regulated market catalog. Most serious traders use both.

Is Polymarket legal in California?

Polymarket takes sign-ups from eligible Californians, and California has not acted against it. The legal question isn't settled: in August 2026 the Ninth Circuit, whose rulings cover California, said at the preliminary stage that state gambling laws can likely apply to sports event contracts, and three petitions are now before the Supreme Court. See our California legality page; this isn't legal advice.

What does Polymarket cost to use?

Polymarket's fee structure and any deposit/withdrawal costs are detailed in the "Fees & payouts" section above. Most CFTC-regulated platforms charge low per-contract fees (typically a few cents per share) plus standard ACH/debit card payment-processor fees. There are no hidden subscription fees on the platforms we recommend.

How do I sign up for Polymarket from California?

Click "Open Polymarket" above (you must meet the platform's minimum age and be a verified US resident). You'll need a government-issued ID, your Social Security number for tax reporting, and a US bank account or debit card for funding. Sign up with your real California address — no VPN needed. Verification typically completes in under 10 minutes.
