Coinbase, Kalshi and Four Firms Back CFTC Over Single-Stock Perps

The trade group suing the CFTC files its reply Tuesday. A judge already found the group likely to win on the law but denied an emergency order on Nov. 3.

Six trading firms led by Coinbase and Kalshi asked a federal judge on Monday, Nov. 9, to let perpetual futures on individual U.S. stocks keep trading, in a letter motion and proposed amicus brief filed in Manhattan. The other side's reply is due Tuesday.

Kraken parent Payward, trading firms DRW and Jump Trading, and a crypto venture investor signed on too; the full list is in the filing. An amicus, or friend-of-the-court, brief lets outsiders argue a case they aren't party to.

How a perp differs from a future

A normal future expires on a set date, when the trade settles. A perpetual never expires. Instead, traders on one side pay the other a regular "funding" fee that keeps the contract's price close to the stock's. Under federal law, security futures are overseen jointly by the CFTC and the SEC, while security-based swaps belong to the SEC alone.

The two arguments

The Capital Markets Alliance Association, whose members include Cboe and Citadel Securities, The Block reported, sued the CFTC on Nov. 3. It says the contracts are security-based swaps and that the agency had no power to approve them. Applications from Kalshi, Coinbase Derivatives and Bitnomial were deemed approved on Nov. 2 after a 45-day review window passed without objection. Alliance secretary Adam Ford said the rollout "erodes investor protection," per Unchained via Yahoo Finance.

The six firms argue the law asks only for delivery at some point in the future, not on a fixed date. A ruling for the alliance would "send equity perpetuals back offshore," their brief says, because the SEC has no framework for retail trading of listed security-based swaps.

Where the case stands

On Nov. 3, Judge Valerie Caproni denied the alliance's request for a temporary restraining order, finding it hadn't shown irreparable harm. Her order also found the group probably would win its claim that the CFTC exceeded its authority. The case is assigned to Judge Lorna Schofield, and the bid for a preliminary injunction is still pending. Black Mint reported the lawsuit on Nov. 3.

In our opinion: the line in that TRO order is the one to read twice. The products survived round one because the harm looked too far off, and the judge sided with the alliance on the law. Tuesday's reply and Judge Schofield's injunction ruling decide whether U.S. stock perps stay onshore.
