Key Takeaways
The Commodity Futures Trading Commission has warned Kalshi that it could face enforcement charges for alleged failures to properly notify the regulator of proposed contracts, adding pressure on the rapidly expanding prediction market industry.
Politico reported that the investigation concerns dozens of products and has continued for months.
The private warning suggests charges could arrive soon, although a settlement remains possible.
The case comes as Democrats prepare tougher congressional oversight and federal regulators examine compliance across competing platforms.

The investigation centers on whether Kalshi met the notification requirements for new products, according to a person with direct knowledge of the probe , as cited by Politico.
Kalshi disputed the reported scale of the issue. Spokesperson Elisabeth Diana described it as a procedural submission error affecting a handful of contracts, many of which never went live.
“We are already addressing the issue,” Diana said.
Kalshi considers its contracts traditional derivatives, a position central to its disputes with state authorities that argue some offerings violate gambling laws.
The reported investigation concerns federal filing obligations, creating a separate compliance question alongside those broader jurisdictional battles.
At the center of the probe is self-certification, a process that allows regulated exchanges to introduce products without obtaining explicit CFTC approval for each listing.
The CFTC’s published procedures require exchanges to submit a written certification before trading begins. Filings must include contract terms, confirmation of compliance with federal derivatives law, and an explanation supporting that assessment.
Exchanges must also publish notice of the pending certification on their websites. The framework gives operators flexibility while placing responsibility on them to demonstrate that products satisfy regulatory requirements.
The agency had already raised concerns about prediction market filings before the reported Kalshi warning.
In a July 24 advisory, its Division of Market Oversight cautioned against broad template submissions that combine numerous potential event contracts into one certification.
Staff said those filings can obstruct scrutiny of settlement methods, data sources and compliance. The guidance also explained circumstances in which closely related contracts may qualify for certification together.
That advisory addressed industry practices generally. It did not establish that Kalshi violated the rules or identify the contracts now reportedly under investigation.
Politico reported that Democrats intend to increase oversight of prediction markets in the next Congress following their midterm victories.
The scrutiny follows substantial industry growth under a CFTC leadership that has generally supported prediction markets, including their position in disputes with state gambling authorities.
Polymarket faces a separate agency investigation that includes whether it violated restrictions associated with its 2022 settlement.
That earlier enforcement action required Polymarket to pay a $1.4 million civil penalty after the CFTC found it operated an unregistered facility offering event-based binary options. The settlement also required it to wind down noncompliant markets and cease further violations.
The two investigations involve different alleged conduct.
Together, however, they suggest that regulatory support for prediction markets does not eliminate scrutiny of how platforms list products or serve customers.
For Kalshi, the next development will be whether the private warning results in formal charges, a negotiated settlement, or another resolution. Until then, the scope and consequences of any alleged filing failures remain uncertain.
