Stock Perps Go to Court: Six Crypto Firms Back the CFTC After a Judge's Blunt November 3 Warning

Can you trade a single US stock as a perpetual future? That's the question sitting in front of a federal judge in Manhattan right now, and six of crypto's most recognizable names just answered it in writing.

Coinbase, Kalshi, Kraken parent Payward, DRW, Jump Trading and approach have asked a court for permission to file a friend-of-the-court brief backing the Commodity Futures Trading Commission. The plaintiff is the Capital Markets Alliance Association, which sued over approvals granted earlier this month for perpetual contracts tied to individual listed companies. Six firms. One regulator. One docket. No final ruling.

The numbers behind the filing

The count that matters isn't six. It's zero.

Zero final judgments on whether these products are lawful. Zero rulings that the CFTC got the statute right. What actually exists is a November 3 order from Judge Valerie Caproni denying the plaintiff's request for a temporary restraining order, plus a proposed brief from six companies that a judge hasn't agreed to accept yet. That's the entire scoreboard.

Read the November 3 order closely, because it's doing a lot of quiet work. Caproni turned down the emergency application, yes. But she indicated the plaintiff was likely to succeed on the statutory question. What the plaintiff failed to show was imminent and irreparable harm, which is the specific bar for a TRO.

So the CFTC didn't win anything. It got a delay. A stay of execution dressed up as a scheduling decision.

In simple terms, the judge told the plaintiff: you're probably right on the law, you just didn't bring me the right emergency. That's a warning, not a vindication.

Why a stock perp is a different animal

A perpetual future gives you price exposure with no expiry date. Crypto traders have lived inside that structure for years and mostly stopped thinking about it. Bolt the same design onto one listed US company, though, and you've walked into a statutory question that predates crypto by decades. Which agency's rules govern the contract? What obligations attach to the exchange that lists it?

The Capital Markets Alliance says these products belong in the securities-law framework, not under the CFTC's treatment of security futures. The six firms counter that the law already permits the agency's approach, and that blocking the products just pushes US-listed alternatives toward offshore venues. Both sides are stating legal positions in a live fight. Neither has been handed a finding.

Think of it this way: the ticker on your screen is identical either way. The legal wrapper around it isn't. Classification decides customer protections, margin requirements, market surveillance, and whether the thing can lawfully be sold to eligible participants at all. Here's why the plumbing matters.

And no, this isn't the same conversation as tokenized shares. A tokenized equity is about representing and settling ownership of a security. A stock perp is a derivative claim on a price, with no dividend and no vote attached. Tying both to the same underlying name doesn't make them the same legal object, and treating them as interchangeable is how people get surprised by a settlement.

What the industry is really buying

Backing a regulator in federal court is an odd look for an industry that spends a good chunk of its public energy complaining about regulators. But that's the tell.

The six firms aren't defending the CFTC out of affection. They're defending the idea that a US-regulated venue can list a product traders already want before the offshore venues take the flow. DRW and Jump don't file briefs for fun. approach doesn't show up unless the structural question touches the whole market. This is a venue question wearing a statute as a coat.

Here's my first real take: the industry should be careful about celebrating November 3. If you win on procedure while the judge signals you're losing on substance, you didn't win. You bought time, and time is expensive when the next hearing is a preliminary injunction on a fuller record.

Second take, and this one's less comfortable. The product likely survives in some form somewhere. The real risk isn't that stock perps disappear. It's that the ambiguity keeps getting resolved slowly enough that the order book quietly builds offshore while US venues wait for clarity. If a contract is legal in one wrapper and questionable in another, and traders genuinely don't care about the wrapper, where do you think the volume ends up?

Perpetuals already carry the bulk of crypto's derivatives volume, running around the clock, seven days a week. That convention isn't going back in the box. Traditional market hours are the anomaly here, not the rule.

What to watch from here

Three concrete things, all of them on the docket rather than in a press release.

First, whether Caproni accepts the proposed outside briefs at all. A court can decline amicus support, and a rejected brief is a signal about how much weight the industry's framing carries.

Second, how the plaintiff's next reply handles the statutory objections. If the answer to that filing is technical rather than structural, the CFTC's position is stronger than November 3 implied.

Third, and this is the one that matters, the preliminary-injunction stage. That's where the statutory question actually gets decided instead of deferred, and both sides get to build a fuller record. Watch that ruling, not the headlines about a denied TRO.

For everyday users, nothing changes overnight. The contracts are still trading while the case moves, and no listing has been permanently authorized by anyone. But the shape of the next few years of US product listings is being set by a judge in Manhattan, not by a token launch or a governance vote.

The perp isn't going anywhere. The only open question is which regulator writes the rules around it, and that answer is coming from a courtroom.
