CME Group is ready to fight. Not in a trading pit — in a courtroom.
Outgoing CME CEO Terrence Duffy announced live on CNBC’s “Fast Money” that the company would file a lawsuit against the Commodity Futures Trading Commission. CME confirmed this shortly after. The target: a CFTC decision made at the end of May, which opened the door for Kalshi to offer perpetual futures on Bitcoin in the United States — a first in the country. For Duffy, this is a red line. He says he has been preparing this with the board for eight months.
Not a knee-jerk reaction, then. A calculated choice.
Swaps or Futures: The Heart of the Issue
The real debate is a matter of classification. Duffy and CME argue that perpetual futures — the so-called “perps” in crypto jargon — are not futures in the legal sense. They are swaps. And that changes everything.
Why? Because under the Dodd-Frank Act, swaps and futures are subject to very different rules: clearing, reporting, authorized trading venues. If perps are swaps, then the regulatory framework that applies to them is completely different. CME says the CFTC misclassified these products, and that the approval granted to Kalshi is fundamentally flawed.
For those unfamiliar with perpetual futures: they are derivative contracts without a fixed expiration date. No settlement on a specific date. Instead, periodic funding payments are exchanged between traders to keep the contract price close to the underlying asset. These products can leverage up to 50 to 1. It amplifies gains. It also amplifies losses, of course.
The CFTC Defends Kalshi — and Coinbase
On the regulatory side, Michael Selig, Chairman of the CFTC, defended the decisions made. For him, approving these regulated perpetual contracts is a way to bring under domestic supervision a significant portion of crypto derivatives currently traded elsewhere, often offshore, often without safeguards. His logic: better to regulate than let them proliferate in the shadows.
Selig to CNBC: “It’s time to approve regulated futures contracts that have no expiration date.”
And the CFTC hasn’t just approved Kalshi. The agency also authorized Coinbase to connect U.S. clients to offshore perpetual futures trading. Two decisions in a short time, in the same direction. The CFTC calls CME’s lawsuit “frivolous” and says it is ready to respond.
Duffy also put another argument on the table: CME holds exclusive licenses on key market indices. His reasoning — any competition on perpetual contracts should go through CME, regardless of their final classification. It’s both a legal and a commercial argument. Probably both at the same time.
A Leadership Change at the Top of CME
The timing of this announcement is no coincidence. CME filed its lawsuit the same day Duffy announced his successor. He will step down in March 2027. Lynne Fitzpatrick, currently President and CFO of the group, will take over as the company’s head — the first female CEO in CME’s history.
Duffy is leaving with a fight. Not exactly the style of a quiet exit.
On the same day, the CFTC faced another legal front, completely separate. A federal judge in the Western District of Michigan, Paul L. Maloney, denied Polymarket’s request for a preliminary injunction against Michigan regulators. Maloney ruled that prediction market bets related to sports are not swaps — and thus do not fall under the CFTC’s jurisdiction.
His wording is direct: the CFTC’s interpretation of its authority over derivatives was, in his view, “so broad that it would encompass entire swaths of activities never associated with the financial industry.”
Two legal challenges on the same day. The CFTC finds itself having to simultaneously handle the lawsuit from the world’s largest futures market operator and a judicial decision that redefines the scope of its authority. Not an easy day.
What is clear: the U.S. crypto derivatives market is entering a phase of serious regulatory turbulence. The question of whether perps are swaps or futures is not just a legal squabble — it will determine who controls this market, under what rules, and for how long. Fitzpatrick will inherit the case in March 2027.
