- Kalshi and Polymarket are among the platforms named in the warning.

- The CFTC continues to support the industry’s growth while increasing scrutiny of compliance.
The Commodity Futures Trading Commission issued new guidance on August 12, 2026. The warning targets prediction market platforms, including Kalshi and Polymarket.
The agency said it is seeing more incentive program filings than before. At the same time, the quality of those filings has gone down.
These filings come through a specific process. Platforms use it to submit or change their own operating rules.
What the CFTC Flagged
The CFTC pointed to two types of programs that worry regulators. The first involves rewards for high-volume traders.
These rewards could push people to trade just to hit volume targets. That raises the risk of wash trading and other manipulative practices.
The second concern involves market-maker programs. Some of these programs guarantee profits or cover losses through stipends and rebates.
The CFTC said this setup could create the same kind of manipulation risk. Traders might act based on guaranteed outcomes rather than real market activity.
A Pattern of Increased Scrutiny
This warning is not the first of its kind. Last month, the CFTC issued a similar advisory about templated event-contract certifications.
Two months before that, the agency proposed its first rule framework built specifically for prediction markets. Together, these actions show a steady pattern.
The CFTC appears to be pushing the industry toward stronger compliance. At the same time, the agency has not moved toward broad enforcement action.
The CFTC has also sided with prediction market firms in separate legal fights. Some state governments have sued these firms over alleged sports-betting violations.
This means the agency is backing the industry’s expansion in court. At the same time, it is tightening the rules platforms must follow while they grow.
Other regulators are also looking at prediction markets. Venture capital firm a16z Crypto has asked the Securities and Exchange Commission to update its own prediction market rules.
State-level friction continues too. Minnesota’s ban on prediction markets is currently paused for Kalshi and Polymarket specifically.
New York has also been part of a separate legal fight involving the CFTC and prediction market platforms.
Platforms running volume-based rewards or market-maker programs may need to strengthen their compliance reviews. The CFTC’s concerns are now part of the public record.
This could mean clearer disclosure of how reward programs calculate payouts. It could also mean better documentation of manipulation risk assessments before a program launches.
Market-maker rebates may also need to be structured more carefully. The goal would be avoiding any setup that looks like it guarantees profit no matter what happens in the market.
For now, the guidance does not change anything for people currently trading on these platforms. Their accounts and positions remain the same today.
However, traders may want to watch how platforms respond. If the CFTC follows up with enforcement, incentive programs could change based on this warning.
