ASA Asks Court to Halt Single-Stock Perpetuals, Citing Retail Harm

The American Securities Association filed a friend-of-the-court brief on November 10, urging a federal court to halt US single-stock perpetuals while it weighs whether the Commodity Futures Trading Commission properly authorized the products. ASA publicized the intervention on November 12 — a two-day gap between the legal event and the announcement that matters to anyone tracking the docket.

The filing backs the Capital Markets Alliance's challenge to the CFTC. But ASA brings a different complaint than the exchanges and trading firms already in the fight. Those parties argue about competitive injury. ASA argues about people.

What does the brief actually claim?

ASA says retail investors face substantial losses from three features of the products: leverage, forced liquidation and trading during thinner sessions. It also argues that stress could transmit into the underlying shares themselves.

These are arguments, not findings. No court has concluded the predicted harm occurred. ASA is asking for a halt while the dispute proceeds — a request its own submission cannot grant. The brief settles nothing about the legal classification of perpetual contracts.

The filing lands in a case already shaped by an earlier order. On November 3, Judge Valerie Caproni denied emergency relief because the plaintiff had not demonstrated imminent, irreparable harm. Yet the judge considered the plaintiff likely to succeed on its statutory-authority argument at that stage. That result was narrower than a final endorsement of the approvals. ASA's retail-harm emphasis speaks directly to the interim-relief question, though the court must decide how much weight it deserves.

Where does the CFTC stand?

Chairman Michael Selig laid out the regulator's position in a November 3 statement. The pathway runs through designated contract markets that also hold notice-registration with the SEC as security-futures products — a structure built on cooperation between the two agencies.

Selig argues that bringing perpetual contracts into regulated US markets gives participants a domestic route to instruments they already use offshore for risk management and price discovery. Crypto and trading firms, including Coinbase and Kalshi, have previously backed the CFTC's position.

The two camps address opposite sides of one trade-off. Supporters emphasize regulated domestic availability. Opponents, ASA among them, dispute whether the chosen legal category preserves the protections the law requires. Framing the debate as regulation versus no regulation misses the actual disagreement.

The contracts under scrutiny

Contract design remains part of the dispute. The SEC's September notice of Nadex contract specifications offers an example: the proposed perpetual products have no fixed expiry, are cash-settled and convey no ownership of the underlying security.

That document describes one venue's filing, not every contract in the lawsuit. Kalshi's separate security-futures listing standards show why individual filings need careful reading — similar product names do not make all terms or regulatory questions identical.

The next decisive development is judicial, not rhetorical. ASA's brief can sharpen the dispute, but only the court's orders establish what changes for the affected products. Any restrictions would depend on the terms and effective timing of an order, something an advocacy announcement cannot deliver.
