What Are Event Contracts? A Plain-English Guide
Event contracts are CFTC-regulated financial instruments that pay $1 if a real-world event happens and $0 if it doesn't. They're not bets, not stocks, and not options, and they're legal in California. Here's how they actually work.
Updated Sep 23, 2026Start Here: common questions
- What is a prediction market?
- A prediction market is an exchange where you buy and sell event contracts that pay $1 if an outcome happens and $0 if it does not. The price, from 1 to 99 cents, reads as the market's probability of that outcome.
- Are prediction markets legal in California?
- Yes. CFTC-regulated platforms such as Kalshi and Polymarket US are available to California residents aged 21+, because event contracts are regulated under federal commodities law.
- How much money do I need to start?
- Most platforms have no or very low minimum deposits, and a single contract costs less than $1, so you can learn with a few dollars before sizing up.
- How is a prediction market different from a sportsbook?
- You trade against other people on an exchange instead of against a house, you can sell your position before the event ends, and prices move with supply and demand rather than set odds.
