CFTC Issues Second Warning to Kalshi and Polymarket Over Blanket Self-Certifications

The U.S. Commodity Futures Trading Commission issued its second advisory on prediction market self-certifications on July 24, 2026, specifically calling out Kalshi, Polymarket's CFTC-regulated US entity, Cboe and Crypto.com's events affiliate for submitting broad template-style certifications rather than individual filings for each contract variation. The advisory follows a July 22 House Agriculture subcommittee hearing on prediction markets and adds new compliance friction to the expansion plans of the major prediction market platforms at a moment when at least 11 US states are also actively moving against sports event contracts.

What Is Prediction Market Self-Certification?

Under the Commodity Exchange Act, designated contract markets (DCMs), the regulatory category covering Kalshi, Cboe and similar platforms, may introduce new event contracts by self-certifying them with the CFTC rather than seeking prior approval for each one. The exchange submits documentation confirming the contract complies with the agency's core principles, including resistance to manipulation and rules promoting fair and equitable trading. The CFTC then has a 10-day window to request a public interest review, which can extend scrutiny to 90 days if the regulator chooses to act.

Carl Kennedy, an attorney at Katten who testified at the July 22 hearing in support of the existing process, argued that it includes meaningful oversight: "That's active oversight with real teeth," pointing to the 10-day request window and the 90-day review capability as checks that the industry's critics tend to understate.

What Did the CFTC Advisory Actually Say?

Acting DMO director Duncan Hennes identified a specific pattern: prediction market operators submitting single template certifications that cover multiple contract variations, each tied to different settlement sources or event categories, as a single bundled filing. The advisory stated directly that "this practice hampers DMO's ability to determine whether a designated contract market has supplied all information" required for compliance review.

Going forward, exchanges must provide "terms and conditions of each proposed permutation and a concise explanation and analysis" for every distinct contract variation. The CFTC said closely related contracts within a single tournament, for example individual match markets within one football competition, may still be grouped. But separate tournaments, sports categories or event types require separate filings with full supporting detail for each one.

Which Platforms Are Most Affected?

The advisory names Kalshi, Polymarket's US entity, Cboe and Crypto.com's event-contract affiliate. Of these, Kalshi is the most exposed operationally. During the 2026 FIFA World Cup, Kalshi processed over $27 billion in trading volume across 33,000 distinct event contracts, a catalogue that was built in part through template-style self-certifications. The new requirement means any comparable future expansion, whether for the next World Cup cycle, a domestic sports season or election markets, would involve significantly more individual filings, slowing the pace at which new contracts can be introduced and increasing per-contract compliance costs.

How Does This Differ From the Ongoing State-Level Legal War?

The CFTC advisory is a federal regulatory action about the process of contract submission under the Commodity Exchange Act. It is a separate track from the state-level legal battles over whether CFTC-regulated sports event contracts violate state gambling laws. At least 11 states have issued formal warnings arguing exactly that, and Minnesota's ban on such contracts takes effect August 1, 2026. Kalshi and Polymarket have challenged those state actions in court, arguing federal CFTC oversight preempts state gambling regulation entirely.

The CFTC advisory does not resolve that preemption question. It focuses only on the mechanics of how exchanges introduce contracts under the existing federal framework. A platform could comply fully with the new filing requirements and still face a state ban on the underlying contracts.

What Did the House Subcommittee Hearing Conclude?

The July 22 House Agriculture Subcommittee hearing on prediction markets did not produce a legislative conclusion. The American Gaming Association's VP Chris Cylke urged Congress to prevent CFTC-regulated prediction markets from self-certifying sports or casino contracts, arguing such platforms lack the consumer protection standards and integrity oversight equivalent to state-licensed sportsbooks. Kennedy's counter-argument, that the self-certification framework already provides active federal oversight with real enforcement tools, reflected the industry's resistance to further legislative restriction.

Observers noted after the hearing that legislation from the House Agriculture Committee was unlikely in the near term. However, the CFTC issued its advisory just two days later, indicating the hearing produced immediate regulatory movement even without a bill passing.

How Does the Advisory Affect Prediction Market Expansion Plans?

The practical effect is to slow new contract launches. Platforms that previously bundled dozens of contract variations into a single self-certification must now file individually for each permutation, including individual settlement methodology explanations. For Kalshi, which processed 33,000 distinct contracts in the World Cup period alone, the compliance overhead of scaling to a similar catalogue for future events is substantially higher under the new standard. For smaller or newer entrants to the DCM market, the added per-contract burden raises the operational cost of competing with established platforms.

What Are the CFTC's Core Principles for Prediction Market Contracts?

The Commodity Exchange Act imposes nearly two dozen core principles on designated contract markets. The two most directly relevant to sports and political event contracts are the requirement that contracts be designed to resist manipulation, and the requirement that exchange rules promote fair and equitable trading. Contracts tied to individual athlete performance or political figure actions, sometimes called single-actor contracts, face particular scrutiny on the manipulation resistance standard because one person's decisions or statements can directly determine how a contract settles.

What Happens to Exchanges That Continue Blanket Filings?

An advisory does not carry the same legal force as a formal CFTC rule, but ignoring it is risky. If the CFTC determines that a submitted self-certification was deficient, it can require the exchange to halt trading on the affected contracts pending proper review. The advisory can also serve as the basis for an enforcement action if an exchange continues the practice after being explicitly warned. Notably, the CFTC framed this as its second advisory on the same issue, signaling that continued non-compliance is likely to attract a firmer regulatory response than the first warning did.

Context: Prediction Markets Under Regulatory Pressure Across Multiple Fronts

The self-certification advisory arrives while the prediction market sector is simultaneously under pressure from states, Congress and international regulators. France blocked Polymarket in July 2026 over illegal gambling concerns, and Polymarket subsequently filed a legal challenge to that order. Pennsylvania introduced legislation aimed at state-level regulation of prediction markets rather than an outright ban. Kalshi's daily trading volume recently reached $2 billion, a sign that commercial growth has outpaced the regulatory frameworks designed to govern the sector.

The CFTC advisory is the federal government's attempt to reassert process discipline at a moment when prediction market platforms are operating at a scale that makes high-level template filings increasingly difficult for regulators to meaningfully review.

Frequently Asked Questions: CFTC Prediction Market Self-Certification Advisory

What did the CFTC tell Kalshi and Polymarket to do?

The CFTC told prediction market exchanges to stop filing single template certifications for broad groups of contracts. Each contract variation must now have its own individual filing including specific terms, settlement methodology and a compliance analysis.

Is prediction market self-certification still allowed after this advisory?

Yes. The CFTC has not removed or suspended the self-certification pathway. It has tightened documentation requirements so that each contract variation is individually reviewed rather than bundled under a single blanket template.

Can states still ban prediction markets even with CFTC oversight?

The legal answer remains contested. Prediction market operators argue CFTC regulation preempts state gambling laws. At least 11 states disagree and have issued warnings or bans. Courts are working through the preemption question, with no definitive federal ruling as of July 2026.

What is a designated contract market (DCM) in the context of prediction markets?

A DCM is a CFTC-licensed exchange authorized to offer futures and event contracts under federal oversight. Kalshi and Cboe hold DCM licences, which is the regulatory basis on which they claim that their sports event contracts fall under federal jurisdiction rather than state gambling law.

When does Minnesota's ban on prediction market sports contracts take effect?

Minnesota's ban on CFTC-regulated sports event prediction contracts takes effect on August 1, 2026.
