CFTC Faces Challenge Over Single-Stock Perpetual Futures as Coinbase and Five Firms Back Regulator
Six crypto and trading firms, including Coinbase and Kalshi, have sought permission to file a brief supporting the CFTC in a lawsuit seeking to halt single-stock perpetual futures. A federal judge denied emergency relief but questioned the regulator's legal basis, and no final ruling has been issued.

What the Firms Filed
Coinbase, Kalshi, Kraken parent Payward, DRW, Jump Trading and Paradigm have asked a federal court for permission to file a proposed amicus brief supporting the Commodity Futures Trading Commission. The filing follows the Capital Markets Alliance Association's challenge to the CFTC's approvals of perpetual futures linked to individual US listed companies. According to The Defiant, the brief backs joint SEC-CFTC oversight, and a reply deadline of November 10 is approaching.
Sources differ on how to describe the filing's scope. The Defiant characterizes it as supporting joint oversight by the SEC and CFTC, while NewsBTC describes it as backing the CFTC's authority more broadly. Both descriptions point to the same core position: the firms want the regulator's approvals to stand.
The Legal Question
A perpetual futures contract gives economic exposure to price movements without an expiration date, a structure common in crypto markets. Applied to a single US company's stock, the product raises a threshold question of which agency's rules apply and what obligations fall on the listing exchange.
The Capital Markets Alliance argues these contracts belong within the securities-law framework rather than the CFTC's treatment of security futures. The supporting firms contend that the law permits the CFTC's approach and that blocking the products would push US traders toward offshore markets. Both are positions in an active dispute, not settled findings.
The Court's Preliminary Ruling
Judge Valerie Caproni denied the request for a temporary restraining order. The denial rested on the absence of the imminent irreparable harm required for emergency relief, not on a finding that the CFTC was right. NewsBTC reports that the judge indicated the plaintiff was likely to succeed on the statutory question, a point that cuts against the regulator even as the immediate request failed.
That distinction matters. An unsuccessful emergency application does not establish that the products comply with the law, and preliminary-injunction proceedings and the merits can still produce further decisions.
What Remains Open
The court has not yet ruled on whether the proposed amicus briefs will be accepted, how the plaintiff's reply addresses the statutory objections, or what relief is appropriate. Neither source describes the matter as resolved, and neither supports the assumption that stock perpetual listings now have permanent authorization.
The classification question also has practical weight. Whether a product falls under securities or derivatives rules shapes customer protections, margin requirements, market surveillance and eligibility to offer the product. A stock perpetual gives a derivative claim tied to a share's price and does not necessarily transfer ownership or voting and dividend rights, which separates it from tokenized securities projects that do represent ownership.
Broader Context
The case tests how US financial regulation adapts to crypto-native trading conventions. Its outcome could shape future listings. For now, the verifiable position is narrower: the CFTC's approvals are under legal challenge, and a group of major crypto and trading firms is organizing to defend them.
Why It Matters
For Traders
Stock perpetual availability on US venues could change if the court later rules against the CFTC, so exposure tied to these products carries legal uncertainty beyond normal market risk.
For Investors
The case will help define whether US regulators treat crypto-style perpetuals on equities as securities or derivatives, a classification that will shape the sector's US product map for years.
For Builders
Products referencing listed equities should be designed with the securities-versus-derivatives question in mind, since structure and jurisdiction, not 24-hour trading alone, determine legal treatment.
