Priced in a Room
Kalshi has built an exchange around putting prices on unresolved questions. One of the biggest unresolved questions now concerns Kalshi itself. New York is challenging whether its core sports business is a federally regulated derivatives market or unlicensed gambling. Less than 2 weeks later, reports emerged that Kalshi was in talks to raise at a $40 billion valuation. The lawsuit's headline damages figure and the reported valuation aren't directly comparable. But together they expose something more interesting: a binary regulatory outcome could materially reshape Kalshi's economics, yet there is no public market continuously pricing that risk. For a company built around markets for uncertain outcomes, perhaps its most consequential contract is the one you can't trade.
Interest disclosure: Tessera PE issues T-Kalshi, a tokenized loan participation right providing economic exposure linked to Kalshi, alongside T-SpaceX and T-OpenAI. Following the SpaceX listing, the investment underlying T-SpaceX is being divested. Redemption opens only once a Redemption Start Date is announced, and as of 20 September 2026 none has been. Tessera's founder, and entities he controls, hold related exposure. Tessera has a commercial interest in Kalshi being interesting; read what follows in that light.
Every private company lacks a market price for itself. That is what private means, and there is no insight in observing it.
What makes Kalshi worth writing about is narrower. The largest open question about the company is binary, near-term, and precisely the class of question its own exchange exists to resolve: is its core sports business a federally regulated derivatives market or an unlicensed gambling operation? Courts will answer it, probably within a year or two, and the answer moves the company's value enormously.
And it is not being priced on an exchange; it is being priced in a room.
Two Numbers That Are Not Comparable
On 31 July, New York Attorney General Letitia James and Governor Kathy Hochul announced a suit alleging Kalshi operates an unlicensed gambling business, sidestepping the licensing and tax obligations that bind regulated operators and reaching users aged 18 to 20 in a state where mobile sports betting requires 21. The complaint seeks an injunction, restitution, disgorgement, treble damages under Penal Law § 80.10, and a $100,000 penalty for each unauthorized sports wagering offer. The CFTC has put the resulting exposure above $36 billion. A coalition of American Indian tribes has backed the state.
On 13 August, The Information reported that Kalshi is in advanced talks with Sequoia and Wellington to raise at least $750 million at a $40 billion valuation. Sequoia is an existing investor; Wellington would be new. The figure is not itself new, since the FT reported $40 billion talks in June, and as of today the round is not closed and none of the three parties has confirmed it.
The two numbers do not belong side by side as though they were commensurable, because they are not. A damages figure in a state complaint is an opening ask built from treble damages and per-offer penalties, and cases like this rarely resolve near the number in the filing.
That is exactly why it is worth noticing. The realistic outcome sits somewhere across a very wide distribution, and nobody is publishing a price for where in that distribution it lands. The company whose product is publishing prices for unresolved questions has this particular question resolved by negotiation among people who already own it.
What Is Actually Known
Growth first, using only closed rounds: $2 billion in June 2025, $5 billion in October 2025, $11 billion in December 2025, $22 billion in May 2026 on a $1 billion raise. Roughly eleven-fold in eleven months, entirely inside a private cap table, against total funding to date of about $2.8 billion. The reported round would take that past $3.4 billion, but it has not happened, and an unconfirmed number does not belong in a growth rate.
The operating trajectory is genuinely remarkable, and nothing below should be mistaken for saying otherwise. Monthly notional volume ran $226 million in December 2024 and somewhere between $29 billion and $31 billion in June 2026 (trackers disagree by a couple of billion depending on what they count), driven substantially by the World Cup. Annualized revenue reached about $4 billion in July, against roughly $260 million of fee revenue for the whole of 2025 and a company-stated run rate above $1.5 billion as recently as May. Sequoia has said Kalshi now claims 95% of the US prediction market. Polymarket's revenue over the comparable period has been reported at $1.1 billion.
The spread of those revenue figures deserves to be taken seriously before any single one is quoted. Four numbers for the same twelve-month window, produced on different bases, is no rounding problem, and a valuation built on the most recent one is underwriting a run rate that has moved by a factor of two or more inside a quarter.
One composition point matters more than any of it. Sports contracts are more than 80% of Kalshi's volume, and approximately 87% of the $39.7 billion trailing twelve-month figure through early 2026 on Congressional Research Service data. Whatever share of that becomes fee-bearing, a separate question given that recently launched perpetual futures currently charge nothing, the legal dispute concerns no peripheral product line. It concerns the overwhelming majority of the business.
The Jurisdictional Question, Fairly Stated
The other side deserves its best argument here, because the version in circulation is too convenient.
The strongest case for Kalshi is statutory rather than a friendly regulator's protection, and it has appellate support. The Commodity Exchange Act gives the CFTC exclusive jurisdiction over swaps traded on designated contract markets, and Kalshi has held that designation since November 2020. On 4 April 2026, the Third Circuit affirmed a preliminary injunction against the New Jersey Division of Gaming, holding that sports event contracts are swaps under the CEA and that the Act preempts state gaming law, the first federal appellate ruling on the question. The Middle District of Tennessee had reached similar conclusions in February. On that reading, a buyer at $40 billion is purchasing a statutory position with a circuit court behind it, which is a materially better asset than a discretionary favor.
The record is genuinely split, though, and the losses are recent. Judge Torres denied Kalshi a preliminary injunction against the New York State Gaming Commission on 7 July. A Michigan state court restrained its sports markets in June and ordered executed trades voided and refunded. Washington won a preliminary injunction in July. Forty-four state attorneys general submitted a letter to the CFTC during a public comment period arguing it has no authority over sports-related event contracts. Kalshi has removed the New York case to federal court, New York has moved to remand, and Kalshi is now asking the Second Circuit to shield its operations. It has separately sued Illinois over a 15% tax on prediction-market sports revenue.
Then there is the federal intervention. On 11 August, the CFTC invoked emergency authority, finding that New York's enforcement action and restraining-order motion amounted to a major market disturbance under the Act, and directed Kalshi to continue operating. Chairman Michael Selig's framing was that Congress did not intend derivatives exchanges to be regulated under a patchwork of state gaming laws. This was the second such intervention on Kalshi's behalf in a month; the first, on 14 July, directed it not to comply with the Michigan court's unwinding order. That authority is rare enough that its previous outings involved potatoes and coffee. The CFTC has separately sued nine states: Arizona, Connecticut, Illinois, Kentucky, Minnesota, New Mexico, New York, Rhode Island, and Wisconsin.
This piece holds no view on who should win, and offers none.
The structural point is narrower. Part of Kalshi's protection is statutory and durable; a circuit court holding survives whoever holds office, and that is the more valuable part. Part of it is enforcement posture: the emergency orders specifically, and the decision to sue states rather than negotiate with them, are choices one commission makes and another could unmake. Those two components have different half-lives and are currently being valued as a single thing.
Which is why the CLARITY Act's stall matters more to this business than to most. The Senate adjourned on 10 August without a floor vote; a cloture motion is set for 15 September and needs sixty votes. Whatever one thinks of the bill, the observation is neutral: a framework established by legislation has a different duration profile from one established by agency posture, and a buyer at $40 billion is long both with no way to price them separately.
The mark doubled between December and May. The jurisdictional question did not resolve in the interval, and has not resolved since.
The Familiar Shape
Kalshi has held early discussions with investment banks and is reportedly eyeing a listing in 2027. Its chief executive has said publicly that a listing is under consideration but not this year. If the reported round closes, it would likely be the last before one. The company has also just brought back Jeff Bandman, the lawyer who secured its CFTC license in 2020, as chief executive of its margin perpetual futures arm, which says something about where the company thinks its defensibility sits.
So the arc is the one this space has been describing for months. A company runs from $2 billion to $22 billion, and reportedly toward $40 billion, entirely inside a closed cap table. The public is invited afterwards, at the end of the compounding phase, at a price the people already inside helped set. An IPO is an exit before it is an entry; Circle remains the compressed illustration, and the numbers need no repeating here.
Monday's piece here made the adjacent point, about SpaceX and capital expenditure: what a public company must mark against itself every ninety days, a private one negotiates. This is the same asymmetry seen from the other end, concerning what gets priced rather than what gets disclosed.
The structure of that argument should not stand in for a view on the business. Kalshi's lead is real, its regulatory head start is real, and Polymarket, whose US entity is itself now a designated contract market, is reportedly seeking more than $20 billion. Two companies have taken almost the entire category. There is a substantial business here, and its integration into on-chain infrastructure is progressing: the Solana-based DoubleZero network added Kalshi's order book to its low-latency data feed on 12 August. The moat is not imaginary; it is simply not yet adjudicated.
What Is Worth Watching
Not the valuation. The valuation is a conclusion.
First, what share of that volume becomes fee-bearing once the promotional period ends, because the difference between an exchange and a subsidized marketplace shows up there and nowhere else.
Second, whether the jurisdictional question is settled by statute and appellate ruling or by administrative order, not because one outcome is better for the company, but because the two have different half-lives, and whoever buys at $40 billion holds both.
The company sells a venue for putting a number on things nobody knows yet. The thing nobody knows about Kalshi is being priced by the handful of people who already own it, which is where the prices that mattered most in this cycle have consistently been set.
