Coinbase Backs CFTC in U.S. Stock Perpetual Futures Fight

U.S. federal judge Valerie Caproni denied a temporary restraining order that would have paused three CFTC-approved single-stock perpetual futures products, leaving the approvals in place during the Capital Markets Alliance’s federal challenge.

The Commodity Futures Trading Commission approved applications from Coinbase Derivatives, Kalshi and Bitnomial on November 2, 2026. On November 10, 2026, Coinbase filed an amicus brief supporting the regulator’s authority; Kalshi and Payward joined the filing. Payward is the corporate parent of Kraken.

The Capital Markets Alliance brought the lawsuit against the CFTC and is contesting whether the regulator should have approved single-stock perpetual futures at all. The case asks a federal judge to draw the line between crypto-style derivatives and traditional equity markets.

A perpetual future has no expiration date. Traders can hold a position tied to an asset’s price indefinitely rather than roll it into a new contract each time the current contract expires.

What does the restraining-order ruling change?

Caproni’s ruling rejects an interim pause, not the products on the merits. A temporary restraining order would have put the approvals on hold while the case continued. The denial leaves the three approvals standing for now, although the underlying regulatory authority remains for judicial review.

Coinbase participates through an amicus brief rather than as a direct party to the lawsuit. The document gives a nonparty a formal way to present its position before judgment. Coinbase’s filing supports the CFTC’s authority over the product category.

How did perpetual swaps reach a federal docket?

Arthur Hayes, the co-founder of BitMEX, said: “Ten years later, Coinbase is in federal court defending the right to offer them on US stocks. I’m flattered.”

BitMEX introduced perpetual swaps in May 2016, when the structure was a fringe crypto experiment rather than the subject of a courtroom fight. Hayes’s comparison points to a crypto-native contract reaching federal court, where approval and jurisdiction now matter as much as product design.

Who is backing the CFTC?

Coinbase officials have framed the dispute around market access. They argue that U.S. investors should have access to derivatives products already available to traders in other parts of the world.

The pro-CFTC coalition brings together different operating models: Coinbase is a crypto exchange, Kalshi is a prediction market, and Payward is the corporate parent of another major exchange. Bitnomial, the third approved applicant alongside Coinbase Derivatives and Kalshi, also has a direct commercial stake.

If the approvals survive, all three approved applicants would be positioned to offer a product that U.S. stock traders have not had in this form. The dispute therefore concerns both regulatory authority and which companies can bring this contract structure into the U.S. market.

What does this change for U.S. stock traders?

The immediate practical effect is limited but consequential: the court has not suspended the approvals, and the three applicants remain positioned to offer the contracts while the litigation proceeds. A final ruling against the CFTC could still disturb that path; the restraining-order denial does not settle the merits.

The immediate legal question is jurisdiction: whether the CFTC had authority to approve the products. If the court affirms that authority, the decision would establish a template for other firms seeking to launch comparable products.

For Coinbase, a victory would also strengthen its effort to expand beyond spot crypto trading into derivatives. For traders, the central issue is whether access broadens through court-approved products or remains limited while the case continues.

Until the court rules on the merits, the three approvals remain operative but legally unsettled. The next consequential checkpoint is that ruling, which will determine whether the CFTC’s approval becomes a template for other single-stock perpetual futures products.
