CME Group plans to file a lawsuit against the Commodity Futures Trading Commission on Thursday, challenging the regulator’s recent approval of perpetual futures contracts. Chief Executive Officer Terry Duffy said the dispute centers on how these derivatives are classified, arguing they should be treated as swaps under the Dodd-Frank Act, which would subject them to stricter oversight.
The legal action follows the CFTC’s May decision to allow bitcoin perpetual futures, approving an application from Kalshi and issuing a no-action position for Coinbase Financial Markets to offer digital commodity derivatives. Perpetual futures enable traders to bet on price movements without owning the underlying asset and do not expire.
Concerns over leverage and review process
Duffy has raised concerns about the level of leverage embedded in the newly approved contracts compared with CME’s existing products. He also questioned the speed of the CFTC’s review, saying it was faster than typical self-certification timelines despite the product’s novel structure.
He warned that growing enthusiasm for leveraged instruments echoes patterns seen before the 2008 financial crisis and could pose risks to market stability. CME said it will pursue the matter through the courts, with Duffy directly overseeing the effort even as he plans to step down in March 2027.
Clash over market structure in the United States
The case highlights a broader conflict over the future structure of the U.S. derivatives market. Perpetual contracts, which have no expiry, could shift trading activity away from traditional futures. Globally, the perpetuals market has expanded rapidly, with trading volume surpassing $60 trillion in 2025.
The CFTC has framed its approval as a way to bring offshore activity into a regulated U.S. environment. However, the lawsuit introduces uncertainty over how quickly these products can grow domestically and whether parts of the approval could be revisited.
Shifting trading patterns and rising competition
Recent data shows a mixed trend across the sector. Average monthly trading volume on the top centralized perpetual exchanges declined from $7.1 trillion in 2025 to $4.7 trillion in the first four months of 2026. At the same time, decentralized platforms have expanded their share from 2.0% in early 2024 to 10.2% by January 2026, processing $2.41 trillion in the first quarter alone.
The rollout of regulated perpetuals is also changing market behavior, requiring traders to monitor positions continuously due to round-the-clock trading. Activity is spreading beyond crypto, with perpetual contracts tied to pre-IPO companies reaching about $12 billion in volume in June, a sharp surge since March.
Regulator defends decision
CFTC Chair Michael Selig has defended the move, saying that making regulated perpetual futures available in the United States is essential for market development. The agency has not yet publicly commented on the expected lawsuit.
