CME Group filed a lawsuit against the CFTC on Thursday, alleging the agency improperly approved Kalshi's first U.S. perpetual futures contract without considering whether those products are actually swaps under Dodd-Frank.
Perpetual futures, or perps, are a crypto-native derivative that never expires. CME is arguing that lack of expiry makes them swaps, not futures, and the CFTC's rubber-stamp approval violates the law.
The Core Dispute: Are Perps Swaps?
CME's lawsuit claims the CFTC "did not engage in its own analysis" of whether Kalshi's Bitcoin perpetual is consistent with the legal definition of a future. The agency "did not even mention the relevant Dodd-Frank provision defining 'swap,'" the suit says, and the word "swap" appears nowhere in the approval order.
Each label carries heavy regulatory baggage. Futures trade on designated contract markets (DCMs) with centralized clearing; swaps face different margin, reporting, and counterparty rules. If perps are swaps, Kalshi's DCM structure alone may be illegal.
Former Starkware General Counsel Katherine Kirkpatrick Bos noted that "future is not defined anywhere" in law, while swap was defined by Dodd-Frank. The CFTC has discretion to categorize novel products, but CME argues an indefinite delivery obligation is not a future delivery. "There is no clear precedent," she said.
What's at Stake for Crypto Perps
On the same day the CFTC approved Kalshi's perps, it sent a no-action letter to Coinbase, effectively opening the door for Coinbase to list perps through an offshore intermediary. The CME lawsuit targets the procedural approval and could set a precedent that halts or reverses those approvals.
CME's outgoing CEO Terry Duffy announced the suit a day before filing, calling it a matter of regulatory consistency. The exchange already lists Bitcoin and Ether futures and options; perps would compete directly with those long-dated products.
A ruling that perps are swaps would force every crypto exchange offering them in the U.S. to either restructure under swap regulations or stop listing. The CFTC's own order is now under judicial scrutiny, and the outcome will define whether perps remain a futures product or get reclassified as a swap-class derivative.
The court's decision on whether "future delivery" requires an expiry date will echo beyond Kalshi and CME. Every crypto perp issuer is watching this case.
