Why the CFTC Is Investigating Kalshi

Key Takeaways

• The CFTC is investigating whether Kalshi properly told it about new event contracts, and Kalshi calls it a procedural error involving a handful of contracts.
• Self-certification lets an exchange list a contract the day after it files, and CFTC staff warned in July 2026 against broad template certifications.
• The same agency is suing states to protect Kalshi’s federal status, and past CFTC event-contract cases ended in penalties, disgorgement and trading bans.

The Commodity Futures Trading Commission is investigating whether Kalshi properly told it about new event contracts, the company confirmed to CNBC on November 11, 2026. Politico had reported a day earlier that the agency privately warned Kalshi charges could come soon. Kalshi says it’s a procedural error involving “a handful of contracts, many of which weren’t live.”

It’s an awkward spot. The CFTC is the federal regulator Kalshi relies on in its fights with the states, and it has gone to court against Utah and nine other states to protect exchanges like it. To see why a filing dispute matters this much, you have to start with how a prediction market gets a contract onto its screen in the first place.

How a Contract Goes Live in a Day

The answer is self-certification. Under section 5c(c) of the Commodity Exchange Act, a registered exchange may list a new contract by giving the CFTC “a written certification that the new contract or instrument” complies with the act and the agency’s rules. There is no approval step. The exchange vouches for its own product.

CFTC Rule 40.2 sets the mechanics. The filing has to reach the agency “by the open of business on the business day preceding the product’s listing,” so a contract certified on Monday can trade on Tuesday. It must carry the contract’s rules, the intended listing date, a certification of compliance and a concise explanation and analysis of how the product meets the act’s core principles, and the exchange has to post a notice on its own website at the same time.

The CFTC isn’t powerless after that. Staff can ask for more information, and the commission can stay a listing “during the pendency of Commission proceedings for filing a false certification.” That last phrase matters here, because it shows the rule itself treats a bad certification as something the agency can bring proceedings over.

Fast by Design

Prediction markets like it this way. At a CFTC advisory committee meeting on August 20, 2026, Kalshi co-founder Luana Lopes Lara defended the process: “We need to be able to have these markets fast for our users.” CME Group chief executive Terry Duffy, a critic, said there had been “2,500 self-certifications since this administration was taking office in January of 2025, of which none have been opposed.”

The Approval Route and the Special Rule

There is a slower road. An exchange can ask the CFTC for prior approval, and the agency then has 90 days to take final action unless the exchange agrees to more time. Duffy’s 2,500 figure shows which road the industry prefers, and that is why the quality of each filing matters so much.

Event contracts also carry an extra limit. Rule 40.11 bars an exchange from listing an event contract that “involves, relates to, or references terrorism, assassination, war, gaming, or an activity that is unlawful under any State or Federal law.” If the CFTC thinks a certified contract might cross that line, it can open a 90-day review and ask the exchange to suspend trading while it decides.

Kalshi Has Been Here Before

Kalshi has already been through that review. It self-certified contracts on which party would control Congress on June 12, 2023, the CFTC opened a review on June 22, and on September 22, 2023 it disapproved them, finding they involved gaming and activity unlawful under state law and were contrary to the public interest. Kalshi sued, and in September 2024 Judge Jia Cobb ruled that Congress hadn’t authorized that public interest review. On May 5, 2025, the CFTC moved to drop its appeal.

Chairman Michael S. Selig wants to rewrite the rule. His June 10, 2026 proposal would define when a contract “involves” a listed activity and flag gaming contracts with heightened risks, such as player-injury and pre-collegiate sports contracts. “My job is to safeguard the integrity of the markets Congress has entrusted the CFTC to oversee, not to decide which ones should or should not exist,” he wrote.

What the July Advisory Said

The warning shot came on July 24, 2026. In Staff Letter 26-22, the CFTC’s Division of Market Oversight said it had seen exchanges “self-certify broad, template event contracts that bundle together potential contract permutations with differing settlement sources and/or methodologies under a single certification.” The agency’s release put it more bluntly: “broad, template-style certifications should not be submitted.”

The letter gave an example of what worried staff. Exchanges had certified contracts on whether unspecified economic events may occur, with “non-exhaustive, vague lists of potential underlyings.” It was also a second warning. Staff had raised the same concern in Staff Letter 26-08 in March 2026, and the July letter said many exchanges kept filing that way anyway.

When One Filing Can Cover Many Contracts

The letter didn’t ban grouped filings. A class certification under Rule 40.2(d) is fine when every contract shares identical pricing sources and settlement methods, such as every match of the 2026 FIFA World Cup, or “daily rainfall totals in a city as reported by the same official weather station.” Matches in the 2026 MLS Leagues Cup can’t ride on a World Cup filing, because the two competitions have different rules.

It ended with a caution. “DCMs should not assume that certifying multiple contracts in a single filing insulates any one contract from individual review,” it said. The letter is a staff view, not a commission rule, and it was addressed to every designated contract market rather than to Kalshi by name.

What Kalshi Is Accused Of

Nothing has been charged, so this is what’s been reported. According to CNBC, the CFTC is investigating whether Kalshi “failed to properly inform the agency of proposed event contracts,” and Kalshi said the agency flagged weather-related contracts. Kalshi didn’t say when the investigation began.

Elisabeth Diana, Kalshi’s head of communications, played it down. “The notice is about a procedural error involving the submission of a handful of contracts, many of which weren’t live,” she said. “We are already addressing the issue.” Kalshi declined to comment on possible charges, and the CFTC didn’t immediately respond to CNBC.

Why Weather Contracts Matter

This is our reading, not the agency’s. Weather is not one of the Rule 40.11 categories of terrorism, assassination, war or gaming, so the reported issue looks like a question of how contracts were filed, not whether they’re gambling. That’s the same ground the July letter covered.

What CFTC Charges Look Like

A CFTC case can go two ways. At the end of an investigation, the Division of Enforcement may recommend administrative proceedings inside the agency, or it can seek relief in a US district court. Administrative sanctions can include civil monetary penalties, restrictions on registration and trading privileges, and restitution. In federal court, the agency can also seek injunctions, an asset freeze and disgorgement of unlawful gains, and it refers criminal conduct to the Justice Department.

The best-known event-contract case is Polymarket. On January 3, 2022, the CFTC issued an order “filing and simultaneously settling charges” that Polymarket ran event markets without registering as an exchange. It had to pay a $1.4 million civil penalty, wind down noncompliant markets and cease and desist. The order said Polymarket had offered more than 900 event markets, and its penalty was reduced for cooperation.

Four Cases That Set the Pattern

The others look different. In 2012 the CFTC sued Intrade and Trade Exchange Network in federal court, partly for filing false “Annual Certification” forms. In April 2026 it charged an Army service member with insider trading in Maduro-related contracts, and in July 2026 it settled with former Congressman George Santos over a State of the Union contract.

None of those four was against a CFTC-designated exchange. Intrade and Polymarket were unregistered, and Van Dyke and Santos were traders. Santos alone had to disgorge $17,569.98 and accept a three-year trading ban.

Why the Timing Is Awkward

Kalshi’s whole case against the states rests on its federal license. The CFTC designated it a contract market in November 2020, and the agency’s own August 2026 emergency order says “Kalshi lists CFTC-regulated event contracts for trading as swaps” and that the commission therefore has exclusive jurisdiction over them. That order came after New York sued Kalshi on July 31 and sought $36 billion in damages, and it directed Kalshi to keep operating.

The CFTC has gone further since. It sued Utah on October 27, 2026, after the state filed civil enforcement actions, and said it had started proceedings against nine other states. “Congress entrusted the CFTC to be the federal regulator with sole responsibility to oversee these markets,” Selig said. On November 5 it gave exchanges 30 days, to December 5, to drop state geofencing or explain why they can’t.

Shield and Referee at Once

The states’ cases turn on whether a sports contract is a swap, and two appeals courts have already ruled that states can regulate them. A filing violation wouldn’t change that legal question. What a case could change is the argument itself. Kalshi tells courts that federal oversight is the reason states should step aside, and an enforcement action from that same overseer would hand states a line for their briefs.

Polymarket Faces Its Own Probe

Kalshi’s biggest rival is under the microscope too. CNBC reported on November 10 that the CFTC is running a broad investigation into Polymarket, covering its advertising and whether it broke its earlier settlement with the agency by letting US residents reach its international exchange. Polymarket’s US exchange, which launched in May, runs separately from that decentralized finance platform.

Polymarket told CNBC its annualized revenue has passed $1.8 billion, and a new $1 billion funding round values it at $21 billion. “We welcome scrutiny,” a spokesperson said.

Selig’s CFTC and the New Congress

Selig said “anyone who engages in fraud, manipulation, or insider trading in any of our markets will face the full force of the law” when the agency charged the Army service member in April. In August the CFTC ordered Kalshi to take down sports-related mention markets, contracts on what someone will say in a broadcast or speech, while it looked into them.

Congress is about to change too. Democrats take control in January, and prediction markets are expected to face more scrutiny then. Rep. Ro Khanna called on X for a ban on sports prediction markets, which make up most of the volume on the big platforms. Those fights will sit on top of the state-by-state legal picture that already decides where Kalshi can operate.

A $40 Billion Company Under Review

The stakes are big. Kalshi announced a $1 billion round on October 29, 2026 that values it at $40 billion, co-led by Sequoia Capital and Wellington Management. It was valued at $22 billion in May and at $5 billion in October 2025.

That valuation rests on a license the CFTC granted and still polices. The agency that called Kalshi’s contracts swaps under its exclusive jurisdiction is now asking whether Kalshi filed them properly.
