The U.S. Commodity Futures Trading Commission issued new guidance Wednesday warning prediction-market platforms such as Kalshi and Polymarket about incentive programs. The agency said filings for those programs are increasingly procedurally or substantively deficient, making it harder to determine whether platforms gave adequate notice of their terms and evaluated compliance. It also warned that volume rewards, stipends and rebates can encourage wash trading, pre-arranged trading and other fraudulent, manipulative or disruptive practices.
Why it matters
Prediction markets use incentives to attract heavy traders and market makers, deepen participation and increase trading volume. But rewards tied to volume targets can push participants to trade solely to qualify, creating risks that activity is manufactured rather than genuine. The CFTC also raised concerns about market-maker programs using stipends and rebates to guarantee net proceeds or cover losses.
The warning comes as the agency takes a leading role in supporting U.S. prediction markets while fighting state challenges over sports-gambling rules. The CFTC proposed its first prediction-markets rule in June and issued a separate advisory last month against cutting corners in templated contract certifications.
Market impact
Platforms now face closer scrutiny of how incentives are designed, disclosed and reviewed. They will need to file complete terms and show that they have assessed compliance. The proposed rule and continuing advisories will help define how rewards, stipends and rebates can operate without inviting the market abuse the agency has warned about.
