    Frequently asked questions

    Does PredictIt have 2028 election markets?

    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.
