Frequently asked questions
What is the CPI prediction market?
- Kalshi lists monthly contracts on the headline Consumer Price Index year-over-year percentage. Contracts come in ranges that resolve YES or NO based on the official BLS release.
When does CPI release?
- Typically the second Tuesday or Wednesday of each month at 8:30am ET.
What predicts CPI best?
- The Cleveland Fed Inflation Nowcast is the single best public predictor. Other inputs: wage data (employment cost index, AHE), energy prices, and shelter components.
How does CPI relate to Fed decisions?
- CPI prints feed directly into Fed FOMC pricing. A hot CPI print typically pushes the next Fed cut probability lower; a cool print pushes it higher.
Are CPI markets legal in California?
- Yes. Macro and economic event contracts on Kalshi are CFTC-regulated and fully legal in California.
Which platform is best for trading CPI data in California?
- Polymarket is the top-ranked choice for CPI liquidity and volume. OG by Crypto.com is the second-ranked option for California residents seeking regulated exposure. Kalshi ranks third and is the primary destination for traders who prefer CFTC-regulated event contracts specifically designed for economic indicators.
Can I withdraw CPI market profits to a California bank account?
- Yes. Kalshi and OG allow direct ACH transfers to California banks. Polymarket requires withdrawing funds to a compatible crypto wallet first, after which the user can transfer funds to a centralized exchange to off-ramp the balance into a traditional bank account.

Responsible Trading
Trading safely: the questions that matter
Is trading prediction markets the same as gambling?
- No. Prediction markets are CFTC-regulated event contracts, financial derivatives, not casino games. That said, you can still lose every dollar you put in. Treat capital at risk as money you are prepared to lose.
How much should I trade with?
- Only with money you can afford to lose without affecting rent, bills, or savings goals. A common rule of thumb: cap total prediction market exposure at 1-5% of your discretionary income.
What are the warning signs of problem trading?
- Trading to recover losses, hiding activity from family, borrowing to fund deposits, missing work or sleep, or feeling unable to stop. If any of these apply, step away and call 1-800-GAMBLER.
Where can I get help in California?
- Call the California Problem Gambling Helpline at 1-800-GAMBLER (free, confidential, 24/7) or visit ncpgambling.org. Most platforms also offer self-exclusion and deposit limit tools in account settings.
Can I set deposit or loss limits?
- Yes. Kalshi, Polymarket, Sleeper, and Chalkboard all offer self-imposed deposit limits, loss limits, and cooling-off periods. Set them when you open the account, not after a bad week.
If you or someone you know needs help, call 1-800-GAMBLER or visit ncpgambling.org.
