A Federal Judge Put Kalshi's Sports Revenue at 90%. Six Days Later It Filed to Become a Stock Exchange.

The most useful sentence written about Kalshi this year came from a judge who was not trying to describe its business model.

Ruling against the exchange on August 10 in the District of Connecticut, Judge Vernon D. Oliver denied Kalshi's preliminary injunction — and Coinbase's, the same day — and in the course of doing so noted that sports contracts account for up to 90 per cent of the platform's revenue. He raised it because it mattered to the legal question. It also happens to be the only figure in the public record that tells you how much of Kalshi rides on the outcome of the litigation.

Ninety per cent. Now look at what the company filed in the week that followed its worst run in court.

The week, in order

September 8: the Tenth Circuit denies Kalshi's emergency motion in the Utah case on all four factors, in two paragraphs.

September 9: Kalshi petitions the Ninth Circuit for rehearing en banc, asking eleven judges to undo the panel that handed Nevada a 3-0 win on August 28. The same day, it self-certifies perpetual futures contracts on gold and silver with the CFTC — no fixed expiry, 24/7 trading, cash settlement, funding payments passing between longs and shorts to keep the contract anchored to the reference market.

September 10: the Southern District of Iowa denies Kalshi's preliminary injunction, with Judge Stephen H. Locher writing that the Commodity Exchange Act "does not meet the mark" on preemption.

September 11: it emerges that Kalshi intends to seek approval for roughly sixty perpetual futures on single stocks and ETFs — Tesla, Apple and Nvidia among them, with a $100 billion market-capitalisation floor for inclusion.

Four filings, four days, two of them in courtrooms and two of them at an agency. A company that is 90 per cent dependent on one product line spent the week its product line was being dismantled applying to sell something else entirely.

Why the route matters more than the product

Self-certification is the fast door. Under it, a registered exchange files a contract and may list it without waiting for a Commission vote, subject to the CFTC intervening if it decides the product is contrary to the public interest or vulnerable to manipulation. Kalshi used that door for gold and silver. It got its Bitcoin perpetual approved in May.

Single-stock perpetuals cannot use that door. They need the SEC as well as the CFTC, because a derivative on Apple stock lands squarely between two agencies that have spent decades disagreeing about where the boundary sits. That is the slowest available process in American financial regulation, and Kalshi is starting it now rather than in 2027 — which tells you the company is measuring the wait against something.

The something is a set of dates it does not control. New Jersey's certiorari petition went to the Supreme Court on September 6; Robinhood and Crypto.com filed their own. If the Court takes the case, nobody is getting an answer before 2027. Kalshi needs a revenue line that does not depend on nine justices.

The escape hatch has its own lawsuit

This is where the hedge gets expensive, and where most coverage stops.

CME Group sued the CFTC in June over perpetual contracts, arguing the Commission reversed its own policy without adequate explanation and that these instruments should be treated as swaps rather than futures. The complaint was aimed at crypto perpetuals. The reasoning is not limited to them, and a ruling for CME would reach gold and silver too.

Citadel Securities has warned regulators that retail single-stock perpetuals risk creating a "parallel shadow market" operating outside normal equity oversight. Better Markets has made the consumer case against 24/7 leveraged products sold to retail. Neither is a disinterested observer — CME and Citadel are incumbents defending a franchise, exactly as the casino industry is in the sports fight — but the substantive objection stands on its own, and Kalshi's answer to it is thin. Tarek Mansour calls perpetuals "the purest form of trading." That is a slogan, not a response to the manipulation question.

So Kalshi's diversification takes it from a business where the states are suing into a business where the largest derivatives exchange in the world is suing. It swaps fifty adversaries for one much better-resourced one.

The demand is real, at least. Blockworks Research data cited this week put leveraged single-stock perpetual volume on Hyperliquid at $212 billion so far in 2026, up from $4 billion at the start of the year. Offshore venues are already running this product at scale for American-adjacent flow. Kalshi's argument — that its leverage is lower than what retail can reach offshore today — is the strongest card it holds, and it is a genuinely good card.

Polymarket is solving the same problem from the other end

On September 10, Polymarket named Warren Jenson its first chief financial officer. Jenson was CFO of Amazon, then president and CFO of Nielsen, then president of LiveRamp; he sits on the boards of Ripple, Dropbox and DigitalOcean. He described the job as putting "capital strategy and operating discipline in place to move quickly at scale."

Companies that hire a first CFO of that seniority are preparing for one of two things: a very large raise, or public-company scrutiny. Polymarket was locked out of the United States by a 2022 CFTC settlement and is now rebuilding a domestic, CFTC-regulated exchange. It is buying financial infrastructure while Kalshi buys product surface. Both are answers to the same question — what is this company if sports go away — and the fact that the two largest players are answering it simultaneously is more informative than either move alone.

The best argument that we have this backwards

Kalshi has been building non-sports markets for years, so reading September's filings as litigation-driven is a story imposed on a coincidence. This is the serious objection and we will not wave it off. Kalshi ran Fed-decision markets, election markets and weather markets before a single state attorney general sent it a letter — and it ran them well enough that in February, Federal Reserve economists Anthony Diercks, Jared Dean Katz and Jonathan Wright published a working paper concluding that Kalshi's markets give researchers and policymakers "a high-frequency, continuously updated, distributionally rich benchmark." Perpetuals on gold have an obvious commercial logic that requires no reference to Nevada at all. Timing is not causation, and four filings in one week is a small sample dressed up as a pattern.

Two things keep us on the other side of it. The first is the 90 per cent. A company with a diversified revenue base does not need a hedge; a company earning nine of every ten dollars from one contested product does, and the judge who supplied that number was reading Kalshi's own submissions. The second is the choice of the fast door for gold and silver while simultaneously starting the slow, two-agency process for equities. That is what it looks like when a firm wants revenue now and optionality later.

There is a third reading we should name because it is not stupid: that filing for sixty stock perpetuals while asking for en banc review is a display of confidence — a company behaving as though it expects to win everywhere. We think the 90 per cent figure rules it out. You do not need optionality on a bet you are sure of.

What we do not know

We do not know Kalshi's revenue mix. We know a federal judge's characterisation of it in August, in a document written for a different purpose, and that is all. We could not obtain the gold and silver certification filings themselves, and we have not seen the single-stock submission, which as of September 11 had been reported rather than published. Valuation figures for both companies are circulating between $15 billion and $40 billion depending on which aggregator you read, and we have not printed one here because we could not stand any of them up.

What is on the record is this: a federal judge put sports at up to 90 per cent of the company's revenue, the company then lost twice more in federal court, asked eleven judges for a do-over, and applied to sell gold, silver and Tesla — the last three inside four days.
