CME Group has taken the Commodity Futures Trading Commission to federal court, contesting the regulator’s approval of Kalshi’s bitcoin perpetual futures contract.
The legal dispute centers on a fundamental classification issue: perpetual contracts do not expire, which sets them apart from traditional futures that settle on fixed dates. CME argues that because perpetuals have no expiry or delivery obligation, they resemble swaps more than futures and should be regulated accordingly under post-crisis U.S. derivatives rules. That distinction matters because swaps face a different regulatory framework than standard futures, affecting how crypto derivatives are listed and supervised in the United States.
The CFTC approved Kalshi’s BTCPERP contract on May 29, allowing Kalshi to list a perpetual contract tied to the spot price of bitcoin. CME’s lawsuit, filed on June 18, argues that a contract with no expiration date or delivery obligation does not fit the usual definition of a contract for future delivery. The outcome could shape how U.S. regulators draw the line between futures and swaps for crypto-linked derivatives going forward.
