California prediction market apps give California residents a chance to trade on sports, news, weather and more. Platforms like Kalshi and Polymarket are federally regulated by the Commodity Futures Trading Commission, with users trading against each other. This guide covers where to trade on sports prediction markets like Bills vs. Rams Monday Night Football game for NFL Week 5. This page also covers the status of California prediction market apps and specific things to know about California trading markets.
Best Prediction Market apps in California
Prediction markets are federally regulated by the United States Commodity Futures Trading Commission (CFTC), which is an agency of the U.S. government. However, the availability of prediction market apps varies state-by-state.
Here are some of the most popular and currently available California prediction market apps and platforms with promos for new users.
Platform | Welcome Bonus | Promo Code |
Kalshi | Trade $25+, receive $55 in bonus trading credits | CBSSPORTS55 |
Polymarket | Deposit $10+, get $25 trading bonus | CBSSPORTS |
Underdog | Play $5, get $100 in bonus entries | CBS |
FanDuel Predicts | Get up to $100 in Bonus Credits When You Trade $1 for 5 Days | |
Novig | Deposit $10, Get $25 in Bonus Trading Credits | None required |
These platforms trade event contracts for real money, allowing users to predict outcomes. Here's a look at some of the available California prediction market apps for sports fans. Please note that platform and market availability may vary outside of California.
How California prediction market pricing works
Prices for these event contracts can fluctuate over time, and users can sell their contracts before an event settles. These contracts pay out $1 for each successful contract. The pricing works the same in each available jurisdiction, which includes California.
For example, if the San Francisco 49ers are priced at $0.25 per event contract (sometimes expressed on prediction markets as 25%) to win a game and they win, the trader will receive $1 for every contract, for a profit of $0.75 per contract.
Kalshi

Things to know about California prediction markets
California prediction markets and federally regulated event-contract markets are rapidly growing. A sports prediction market does not operate like a sportsbook. Platforms rely solely on licensing and regulation by the CFTC, a federal agency of the U.S government.
They are not subject to California gaming licenses; however, this is being debated in courts.
