The US Commodity Futures Trading Commission (CFTC) issued guidance on August 12, 2026 warning prediction market platforms, including Kalshi and Polymarket, that many of their incentive program filings are procedurally or substantively deficient.
What the CFTC Is Concerned About
The agency said it’s seeing a rising number of incentive-related filings, making it difficult to determine whether a platform adequately disclosed its program terms or properly evaluated the program’s compliance.
The CFTC receives these filings through its trading organization rule submission process, the channel registered exchanges use to submit and amend their own operating rules, and the core message of this guidance is to reduce deficiencies coming through that specific channel.
Even as the number of these filings continues to rise, the agency said their overall quality has declined, with a growing share falling short on procedure, substance, or both.
Two categories of incentive programs drew particular concern. Rewards aimed at high-volume traders could encourage people to trade specifically to hit volume targets, according to the government agency, heightening the risk of wash trading, pre-arranged trades, and other manipulative or disruptive practices.
Separately, market-maker programs that guarantee profits or cover losses through stipends and rebates could create similar incentives toward manipulation, the agency said.
This Fits a Broader Pattern, Not a One-Off Warning
This guidance follows an advisory the CFTC issued last month warning prediction market platforms against cutting corners in templated event-contract certifications, and it comes just two months after the agency proposed its first dedicated rule framework for prediction markets in June.
Taken together, this reads as a continuation of the CFTC’s approach so far, steering the industry toward compliance with existing rules while remaining broadly supportive of the market’s growth rather than moving toward broad enforcement action.
The agency has also taken the industry’s side in separate legal disputes with state governments that sued prediction market firms over alleged sports-betting regulation violations, a dual posture that enables the industry’s expansion while simultaneously tightening the scrutiny it applies to compliance during that expansion.
The regulatory landscape around prediction markets extends well beyond the CFTC as venture capital firm a16z Crypto has separately urged the Securities and Exchange Commission (SEC) to update its prediction market rules, and friction continues at the state level as well.
Minnesota’s prediction market ban, for instance, has been temporarily suspended specifically with respect to Kalshi and Polymarket. Our earlier coverage of the CFTC’s legal fight to protect prediction markets from New York addresses a related aspect of this jurisdictional contest.
What Comes Next
Platforms running volume-based rewards or market-maker programs will likely need to strengthen their internal compliance reviews before submitting future incentive filings, given that the CFTC’s stated concerns are now on public record.
In practice, that could mean more detailed disclosure of exactly how a reward program calculates payouts, clearer documentation of how a platform evaluated manipulation risk before launching an incentive program, and more conservative structuring of market-maker rebates to avoid arrangements that appear to guarantee profit regardless of the trading outcome.
What this means for you: if you trade on a prediction market platform running an active rewards or volume-incentive program, this guidance does not change anything about your account or positions today, but it does suggest those programs could face real changes if the CFTC follows up with enforcement, so it is worth watching whether any platform you use adjusts its incentive structure in response.
