    Frequently asked questions

    Are prediction market winnings taxable in the US?

    Yes. All prediction market profits are taxable income at both the federal level and state level. There is no federal de minimis exception. Even small profits are reportable, regardless of whether the platform issues a 1099.

    Does Kalshi send a 1099?

    Kalshi historically issues 1099-B forms to users who hit reporting thresholds. The form arrives in January or February for the prior tax year and is also available in your account's tax documents section.

    Does Polymarket send a 1099?

    Polymarket does not currently issue 1099 forms to US users. You are responsible for self-reporting all profits. Use the platform's CSV export to track activity.

    What is Section 1256 treatment?

    Section 1256 of the Internal Revenue Code provides 60/40 tax treatment for qualifying regulated futures contracts: 60% long-term capital gains, 40% short-term, regardless of holding period. Some prediction market contracts may qualify; consult a CPA.

    Are USDC conversions on Polymarket taxable?

    Technically, yes. Each USDC-to-USD conversion is a separate taxable event under crypto tax rules. The amounts are usually negligible since USDC is pegged to USD, but they should be tracked.

    Can I deduct prediction market losses?

    Yes, with limits. Capital losses can offset capital gains plus up to $3,000 of ordinary income per year. Excess losses carry forward. 1256 contract losses have additional carryback options.

    Is this tax advice?

    No. This article is general information only. Consult a licensed CPA, ideally one familiar with derivatives or 1256 contracts, before filing.

    Responsible Trading

    Trading safely: the questions that matter

    Is trading prediction markets the same as gambling?

    No. Prediction markets are federally-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 the US?

    Call the National 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.
