CME Group, the world’s largest derivatives exchange operator, filed a lawsuit against the Commodity Futures Trading Commission on Thursday alleging the agency violated federal law when it approved Kalshi’s perpetual futures contracts last month. The suit asks a federal court to vacate both the approval and the self-certified products that followed it.
The filing came one day after outgoing CEO Terry Duffy announced CME would take legal action. It is, to put it plainly, not something you see every day: a company with CME’s market position suing its own primary regulator over a competitor’s product approval.
CME’s Core Argument: Perps Are Swaps, Not Futures
The legal dispute hinges on a definitional question that might sound academic but carries real regulatory consequences. CME contends that perpetual futures, the crypto-native derivative products commonly called perps, are actually “swaps” as defined by the Dodd-Frank Wall Street Reform and Consumer Protection Act, not “futures.”
Why does the label matter? Under Dodd-Frank, swaps and futures face different regulatory frameworks. The rules governing who can trade them, what capital requirements apply, and how they must be cleared differ substantially. If perps are swaps, Kalshi’s self-certification route may have been improper from the start.
CME’s lawsuit makes a pointed observation about the CFTC’s approval order: “The CFTC did not engage in its own analysis of whether its approval of Kalshi’s Bitcoin perpetual as a future is consistent with law. The CFTC did not even mention the relevant Dodd-Frank provision defining ‘swap.’ Indeed, the word ‘swap’ appears nowhere in the Order.”
The exchange giant characterizes the approval as a “rubberstamp” of Kalshi’s application rather than the independent analysis Dodd-Frank requires. This procedural angle gives CME a basis for the lawsuit even if the underlying classification question remains unsettled.
What Makes Perps Legally Ambiguous
Perpetual futures occupy an unusual corner of the derivatives world. Unlike traditional futures contracts, which specify a delivery date when the contract settles, perps have no expiration. They can theoretically run forever, with traders paying or receiving periodic funding rates to keep the contract price anchored to the underlying spot market.
This structure made perps wildly popular in crypto markets. Offshore exchanges like Binance, Bybit, and OKX built enormous businesses around them. At their peak, crypto perps routinely saw more daily volume than the spot markets they track. The instruments let traders take leveraged positions without worrying about rolling contracts before expiration, simplifying the whole experience.
But that same feature, the absence of expiration, is what CME now argues makes them swaps rather than futures. The Dodd-Frank Act defines swaps partly in contrast to “contracts of sale of a commodity for future delivery.” CME’s theory, as summarized by former Starkware General Counsel Katherine Kirkpatrick Bos, is that “future delivery” implies an actual delivery date. No delivery date, no future.
Kirkpatrick Bos noted on X that this argument faces a complication: “Future is not defined anywhere, whereas swap was defined by Dodd-Frank. The CFTC has the discretion to categorize novel products that have the characteristics of a future as opposed to swap.” She added there is “no clear precedent” establishing that “future delivery” requires an expiration.
So the legal question is genuinely open. Perps are a novel product that Dodd-Frank’s drafters likely never contemplated when they wrote the law in 2010, years before these instruments became a cornerstone of crypto trading.
The Competitive Stakes for CME
CME’s lawsuit is not purely a matter of regulatory principle. The company states plainly that perpetual futures threaten its existing business. The suit alleges these products “are harmful to its long-dated futures products,” meaning CME sees Kalshi’s perps as a direct competitive threat.
This makes sense when you consider how futures trading works. CME operates massive, highly liquid futures markets in Bitcoin and Ethereum. Institutional traders use these markets for hedging and speculation. But CME’s contracts expire monthly or quarterly, requiring traders to roll positions forward if they want continued exposure.
Perps eliminate that friction. A hedge fund or prop shop could take a position and hold it indefinitely, adjusting only for funding costs. If perps gain traction on regulated U.S. platforms, some volume currently flowing through CME’s expiring contracts might shift to the no-expiration alternative.
The timing of CME’s move is notable. Duffy announced the suit would come shortly after the CFTC’s approval of Kalshi’s application at the end of May. He told CNBC last week that the futures-versus-swaps distinction “mandates different rules for participants.” A day later, CME made good on the threat.
The Broader Perps Landscape Is Expanding Fast
Kalshi is not the only company pushing into the U.S. perpetual futures space. On the same day the CFTC approved Kalshi’s application, the agency sent a no-action letter to Coinbase. That letter apparently opens the door for the exchange to list perps as well, though through an offshore intermediary rather than direct U.S. issuance.
The regulatory approach here looks like a patchwork. Kalshi secured a designated contract market (DCM) approval, the traditional route for listing futures in the U.S. Coinbase’s path relies on a no-action letter, which is essentially the CFTC saying it will not pursue enforcement for a specific activity for now. These are not equivalent regulatory postures.
If CME’s lawsuit succeeds and perps get reclassified as swaps, both Kalshi’s approval and Coinbase’s no-action comfort could face new questions. Swap execution facilities operate under different rules than futures exchanges. The capital, reporting, and participant requirements differ. Companies that built business plans around perps-as-futures might need to rethink their approaches.
The market for perpetual futures products listed by regulated U.S. entities is still nascent, but the interest is clearly there. Multiple firms have sought or are seeking DCM status. The CFTC’s willingness to approve Kalshi’s application signaled a green light that others planned to follow. CME’s lawsuit throws a wrench into that momentum.
Dodd-Frank’s Definitions Were Not Built for Crypto
The deeper issue here is that the Dodd-Frank Act, passed in 2010 in response to the financial crisis, was not written with crypto derivatives in mind. Its swap definition was designed to capture over-the-counter interest rate swaps, credit default swaps, and similar instruments that had contributed to systemic risk. The drafters were thinking about AIG and Lehman Brothers, not about a futures contract on Bitcoin that never expires.
Perpetual futures emerged in crypto markets around 2016, six years after Dodd-Frank became law. The BitMEX exchange popularized the structure, and it spread rapidly across the offshore crypto ecosystem. By the time U.S. regulators started thinking seriously about bringing these products onshore, there was no clear statutory home for them.
The CFTC has historically exercised discretion in categorizing novel products. When something looks more like a future than a swap, functions like a future, and trades like a future, the agency has generally been willing to treat it as a future even if the precise statutory definition does not fit perfectly. CME is now challenging that discretion.
The outcome could have implications beyond crypto. If courts establish that an expiration date is essential to the definition of a futures contract, that principle would apply across asset classes. Financial engineers designing new products would need to factor in the legal boundary.
What Happens Next in the Courts and Congress
CME’s lawsuit will play out in federal court, likely over many months. The company is asking for the CFTC’s approval to be vacated, which would be a significant win. But even if CME prevails on procedural grounds, that does not necessarily mean perps are swaps. It might just mean the CFTC needs to go back and do a more thorough analysis before reapproving the products.
Meanwhile, Congress is paying attention to digital assets and derivatives. The House Financial Services Committee has hearings scheduled this week on “Future of Payments” and “The Future of How America Invests,” though speaker lists have not been disclosed. The House Oversight Committee’s Subcommittee on Military and Foreign Affairs will hold a hearing on digital currencies Thursday.
The Senate Banking Committee is holding a hearing Tuesday on “The Affordability Agenda” featuring Digital Chamber CEO Cody Carbone, among others. While that hearing’s focus is broader, the presence of crypto industry representation suggests digital asset issues could come up.
If lawmakers wanted to resolve the perps classification question definitively, they could amend Dodd-Frank to explicitly address perpetual futures. Legislation could either classify them as futures, classify them as swaps, or create a new hybrid category with tailored rules. That would take the question out of the courts and the CFTC’s hands.
But legislative solutions take time, and Congress has not shown urgency on derivatives classification. The GENIUS Act focused on stablecoins. Market structure bills have stalled. For now, the courts are the forum where this gets decided.
A Preview of More Classification Fights
CME’s lawsuit is part of a broader pattern. As digital assets mature and seek integration with traditional financial infrastructure, definitional questions keep arising. Is Ethereum a security or a commodity? Are staking rewards interest? Is a wrapped token the same as the underlying asset? Each question carries regulatory implications, and each answer shapes what products can reach U.S. investors and how.
The perps-versus-swaps dispute fits this mold. A product that has traded freely offshore for years is now bumping into a regulatory framework that was not designed for it. The outcome will determine whether perpetual futures can become a standard offering on U.S. regulated exchanges or whether they remain largely offshore instruments.
For traders who use the derivatives markets, the stakes are practical. Perps offer capital efficiency and simplicity that traditional futures lack. If they become widely available on U.S. platforms, retail and institutional participants both gain access to tools the offshore market has had for years. If they get classified as swaps, the path to U.S. listing becomes harder, the participant requirements become stricter, and the offshore advantage persists.
CME’s lawsuit is ultimately about competitive positioning. The company sees a threat to its futures business and is using the legal system to slow it down. Whether the legal arguments hold up is a separate question from whether they are motivated by genuine concern about Dodd-Frank compliance versus concern about market share. Both can be true.
The CFTC has not yet responded publicly to the lawsuit. Paul Atkins, the current SEC Chair, has pushed for clearer crypto rules, but the CFTC operates independently. Chair Rostin Behnam’s term continues, and the agency’s approach to novel crypto products has been incrementally permissive. Whether that changes under litigation pressure remains to be seen.
For the crypto industry, this lawsuit is a reminder that regulatory clarity does not come easily. Even when an agency grants approval, competitors may challenge it. Even when products fit existing frameworks awkwardly, courts may force regulators to explain their reasoning. The path from offshore product to fully regulated U.S. offering runs through more obstacles than a single approval letter.
Perpetual futures will eventually find a stable home in U.S. regulation. The question is whether they land as futures, swaps, or something new, and how much legal fighting happens along the way.
