CME Group intends to sue the Commodity Futures Trading Commission over the regulator's approval of Kalshi's perpetual futures product, CME chief executive Terrence Duffy said. Duffy argues the product doesn't meet the legal definition of a swap under the Dodd-Frank Act and should never have been cleared for trading.
The legal argument
Duffy's claim centers on the Dodd-Frank Act's definition of a swap. The 2010 law lays out specific criteria for what counts as a swap, and Duffy says Kalshi's perpetual futures miss the mark. Perpetual futures are a type of derivative contract that doesn't expire, widely used in crypto markets. Kalshi, a predictions market platform, received CFTC approval to offer such a product earlier this year.
CME, the world's largest futures exchange, sees the approval as a regulatory overstep. By approving Kalshi's product, the CFTC allowed something that doesn't fit the legal framework, Duffy contends. The lawsuit will challenge that decision directly.
What's at stake for regulated markets
If CME succeeds, it could force the CFTC to reconsider how it classifies novel financial products. The case touches on the boundary between traditional futures contracts and swaps, a distinction with major implications for market oversight and capital requirements. Kalshi's product already launched under the CFTC's blessing, so any legal ruling could upend existing positions.
The lawsuit also puts CME in an unusual position: a regulated exchange suing its own regulator. The exchange has a history of pushing back on rule changes, but a direct challenge to a specific product approval is rare.
The next move
CME hasn't filed the suit yet, but Duffy's public statement signals it's coming. The CFTC hasn't responded to the planned lawsuit. Kalshi, which is not named as a defendant, is likely to watch closely — the outcome could determine whether its perpetual futures survive. No court date has been set, and the legal process could stretch for months.
