Wall Street group sues CFTC, judge lets stock perps trade

A group of Wall Street firms sued the US derivatives regulator this week over its move to let Americans trade perpetual futures tied to single stocks. A federal judge refused to halt the trading the same day, then said the challengers would probably win.

The complaint landed on 3 November in the US District Court for the Southern District of New York, filed as case number 1:26-cv-09608 against the Commodity Futures Trading Commission, according to reporting by CoinDesk and Bitcoin Magazine. The plaintiff is the Capital Markets Alliance Association, a New York nonprofit.

Who sued, and what they want

Behind the alliance stand some of the biggest names in US stock trading. Its members include Cboe Global Markets, Citadel Securities and the Healthy Markets Association, CoinDesk reported. These firms make their money in the regulated equity market, and they do not want a rival product growing up under a different set of rules.

They argue that the new contracts are securities, not commodities. That would put them under the Securities and Exchange Commission, not the CFTC.

Two claims sit at the heart of the case. First, the suit says equity perpetual futures are securities-based swaps, which belong to the SEC. Second, it says the CFTC broke the Administrative Procedure Act, the law that governs how federal agencies make policy, by failing to explain why its new stance contradicts an earlier one. The group wants it scrapped.

Chris Iacovella, president and chief executive of the American Securities Association, backed that reading. 'By labeling stock perps as security futures, the CFTC sidestepped the SEC's jurisdiction,' he said in comments reported by CoinDesk.

What the judge decided

US District Judge Valerie Caproni turned down an emergency request to stop the trading, Bitcoin Magazine reported. Her order left the CFTC's approvals in place. It did not decide the case.

But the judge did not side with the regulator on the main legal question. She wrote that the alliance is 'likely to succeed on the merits' of its claim that the CFTC lacks the statutory authority for these products. A perpetual contract has no fixed delivery date, she noted, so it 'cannot be a security future' as the law defines one. The contracts instead 'appear to satisfy the definition of a swap,' which points back toward the SEC.

That distinction sounds dry, but it decides a lot here. A security future settles on a set date against a named stock. A swap is a broader deal tied to an asset's value over time. By ruling that a never-expiring contract fits the swap definition, the judge pushed the whole product toward the SEC's side of the line.

Caproni refused the halt for a narrower reason. The firms had not shown they faced immediate harm. She called their supporting statements 'conjectural' and said the claimed damage was not 'actual and imminent.' So the products keep trading. A narrow win for the agency, at best.

A fight over who regulates what

This case is the latest round in a long turf war between the CFTC and the SEC. The two agencies have spent years arguing over who should write the market-structure rules for digital assets. Perpetual futures on single stocks sit awkwardly across the line that splits them.

Money drives this as much as the law. Perpetual futures trade around the clock and let investors borrow to hold bigger positions without rolling a contract over every month. That makes them cheaper to keep open than standard futures. Crypto venues built big volumes on them offshore, and US firms now want a share of that. Established players such as Cboe would rather the business arrive through the system they already run.

CFTC Chairman Mike Selig framed the move as a careful step, not a land grab. In a statement on 3 November, he said equity perpetual futures could trade only on markets that are also registered with the SEC. He called the contracts 'widely sought tools for risk-management and price-discovery' and said bringing them onshore keeps American traders 'within the protections of the CFTC's proven regulatory framework' instead of sending them to offshore venues. The two agencies, he added, wanted clarity 'rather than more casualties of jurisdictional disputes.'

The regulator was blunt about the lawsuit. 'Our markets should be governed by law, not litigation campaigns intended to block innovation,' a CFTC spokesman said. Still, the judge's early read of the law cuts against that confidence.

Regulators did not open this door overnight. The CFTC had already cleared a crypto version of perpetual futures earlier in 2026, CoinDesk noted, before its 3 November statement stretched the idea from digital commodities to shares. That stretch is what the lawsuit targets. The SEC has not weighed in publicly on the dispute, according to the available reporting.

Those contracts already trade on Kalshi, Coinbase Derivatives and Bitnomial, Bitcoin Magazine reported. Perpetual futures let traders bet on a price with no expiry date, a format that crypto exchanges made popular offshore before the CFTC cleared a US version of the contracts days earlier.

What to watch

Deadlines come fast. The CFTC's response to the lawsuit is due on 6 November, and the alliance's reply is due on 10 November, Bitcoin Magazine reported, though the assigned judge can change those dates. A decision on a longer freeze, called a preliminary injunction, would come after that.

A harder question hangs over all of it. If the court agrees that single-stock perpetuals are really securities, the ruling could push the products back under the SEC and undo a policy the CFTC rolled out only days before. It could also set limits on how far either agency can stretch its reach as more traditional assets move onto crypto-style rails. For now the contracts trade on. The law behind them does not look settled.
