The Commodity Futures Trading Commission is investigating whether Kalshi properly notified it about new event contracts, and Kalshi has confirmed it. The company told CNBC on 11 November 2026 that the agency flagged weather-related contracts. A day earlier Politico reported, citing one person with direct knowledge, that the CFTC had privately warned Kalshi of possibly imminent charges over “dozens of new products”, which could also end in a settlement. No charge or order has been filed: the newest item on the CFTC press release list is from 9 November and does not concern Kalshi.
What Kalshi says
Kalshi’s head of communications, Elisabeth Diana, called it “a procedural error involving the submission of a handful of contracts, many of which weren’t live” and said the company is “already addressing the issue”. So the two accounts differ on scale: a handful of contracts in Kalshi’s words, dozens of products in Politico’s source’s. CFTC Chairman Michael Selig told CNBC the agency does not comment on investigations.
Why filing matters
Exchanges like Kalshi don’t need CFTC approval for each new contract. Under 17 CFR 40.2 they can self-certify that a product complies with the Commodity Exchange Act, but the filing has to reach the CFTC before the product is listed. That rule is how Kalshi can add markets quickly, and it is the step the probe is about. The CFTC already made Kalshi pull sports “mention markets” in August, CNBC notes, even as Selig sides with prediction markets against the states, for example in his impartial access interpretation of 5 November.
Our numbers: weather is a sliver
We pulled Kalshi’s public series list on 12 November and its daily market data reports for 1 October to 11 November. Kalshi lists 505 “Climate and Weather” series out of 16,231, about 3%: daily highs and lows by city, rainfall, snow, hurricanes. Between 107 and 150 of them traded on any given day. Those series did $114.3 million of volume in October, 0.12% of Kalshi’s $98.15 billion, and $35.9 million (0.08%) from 1 to 11 November. We can’t tell from public data which contracts the CFTC flagged.

Why it matters for GambleFi
Weather is a tiny business for Kalshi, so a fine over it would hardly hurt. The point is the process: self-certification lets prediction markets list thousands of contracts fast, and the CFTC under Selig is now showing it will police that step even while it defends the industry in court. Kalshi raised money at a $40 billion valuation and set a $5.36 billion volume record on 8 November, and Polymarket, now also under a broad CFTC probe per CNBC, has been growing revenue fast, so how cleanly these exchanges file their products now matters more. For onchain prediction markets and iGaming token projects outside the CFTC system there is no such filing step at all.
