Coinbase, Kalshi, Kraken Back CFTC in Stock Perpetuals Court Fight

Six of crypto's most prominent companies — Coinbase, Kalshi, Kraken parent Payward, DRW, Jump Trading and Paradigm — have asked a federal court for permission to back the Commodity Futures Trading Commission in litigation over perpetual futures tied to individual US stocks. Their proposed friend-of-the-court brief, filed in the US District Court for the Southern District of New York, supports the CFTC's authority to permit the products, which won approvals earlier this month.

The case pits the Capital Markets Alliance Association against the regulator. The association argues the contracts belong within the securities-law framework rather than under the CFTC's treatment of security futures. The intervening companies counter that the law permits the agency's approach and that blocking the products would push US-listed alternatives toward offshore markets. Both are legal positions in an active dispute — neither side has won a final ruling.

What did Judge Caproni's November 3 order decide?

In a published federal court order, Judge Valerie Caproni denied the plaintiff's request for a temporary restraining order, meaning the products stayed live at that stage. But the order was not a broad endorsement of the CFTC's position. Caproni indicated the plaintiff was likely to succeed on the statutory question while failing to show the imminent irreparable harm required for emergency relief.

That split matters. A failed emergency application is not a judgment that the products comply with the law. A preliminary-injunction fight and the broader merits remain open, and both sides can submit further arguments.

Why does classification drive the outcome?

A perpetual futures contract gives traders economic exposure to price changes with no preset expiration — a familiar structure in crypto markets. Applying it to a single listed US company raises a separate statutory question: which agency's rules govern the product, and what obligations attach to the exchange that lists it?

The answer determines more than where an order is matched. Classification shapes customer protections, margin rules, market surveillance and whether a product can lawfully be offered to eligible participants at all.

Are stock perps the same as tokenized shares?

No, and the distinction is doing legal work. A tokenized share — as in the NYSE's proposed tokenized securities venue — represents and settles actual security ownership. A stock perpetual gives a trader a derivative claim whose value is linked to a share; it does not necessarily transfer ownership of that share or its voting and dividend rights.

Similarly, Ripple Prime's round-the-clock swaps referencing real-world assets show how conventional markets can be referenced by crypto-native derivatives. The legal treatment of each product depends on its structure and jurisdiction, not simply on whether it trades 24 hours a day.

What happens next?

The immediate questions are threefold:

• Whether Judge Caproni accepts the six firms' proposed amicus briefs
• How the plaintiff's latest reply answers the statutory objections
• What relief the court considers appropriate if it rules for the association

There is no basis to call the matter settled, and no stock perp listing should be read as permanently authorized.

The case is a serious test of how US financial regulation adapts to perpetual trading conventions. Its outcome could shape the structure of future listings — but the narrower fact today is that the CFTC's approvals are under challenge, and the industry is organizing a legal defense.
