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.
