A billion dollars is a large ask for a company whose core product is currently being regulated out of existence in three states simultaneously.
Kalshi is in talks to raise at that figure, according to reporting from this week. The number is attention-grabbing, and deliberately so — a valuation that size reframes a regulatory siege as a growth story. It is worth sitting with why that framing is doing so much work right now.
The legal situation is not abstract. The Sixth Circuit has ruled against Kalshi on sports contracts twice. Ohio and Tennessee have won interim control of those contracts in their jurisdictions. New Jersey has asked the Supreme Court to hear its challenge. Arizona's attorney general is attempting to reopen the Ninth Circuit case. Three congressional candidates have been suspended from the platform for betting on their own races, which is the kind of headline that regulatory opponents clip and keep. The CFTC has filed suit against several states to protect the platform's federal preemption argument, but that argument has now failed its most direct judicial test.
This is the context inside which someone is being asked to write a cheque that implies Kalshi is worth more than the London Stock Exchange.
My read is that the valuation is not delusional — it is a specific bet on a specific outcome, and the people writing it know exactly what they are pricing. If the Supreme Court takes the New Jersey case, or if Kalshi's own petition for certiorari succeeds, a single ruling in their favour collapses the state-by-state litigation into one resolved question. The winner of that ruling gets the American prediction market. The loser probably doesn't. A forty-billion-dollar entry price is bearable if the upside is a federally protected monopoly position in a market that processed nearly twenty billion dollars in volume this year.
What troubles me is the distance between that scenario and the current judicial trend. Circuit courts are not advisory bodies. Two Sixth Circuit rulings and a procedural loss in Ohio represent actual legal outcomes, not positioning. Investors in this round are pricing a Supreme Court reversal of a direction that, so far, the federal judiciary has not shown any appetite to go.
I have been wrong before about how long a losing legal position can be funded. Capital can sustain a bad argument for years, and years is sometimes all you need when the political environment shifts. The CFTC's posture under the current administration is clearly sympathetic to Kalshi's federal preemption theory, and an agency willing to sue three states on your behalf is not nothing.
But the investors getting the forty-billion-dollar pitch should understand they are not buying a prediction market. They are buying a litigation outcome that has not happened yet, at a price that assumes it will.
Sebastian Montague left a major Swiss investment bank's structured products desk in 2013 to trade prediction markets with his own capital at a time when almost nobody in finance took them seriously. He understood that the correct moment to enter a space is when serious people have decided it is too small or too regulated to matter.

Kalshi argues that the Commodity Exchange Act grants it federal authority to operate prediction markets nationwide, preempting individual state bans. This theory rests on the CFTC's interpretation that certain prediction contracts fall under federal jurisdiction rather than state gambling law. The federal preemption argument has now failed its most direct judicial test, with the Sixth Circuit ruling against Kalshi on sports contracts twice and Ohio and Tennessee winning interim control of those contracts in their jurisdictions.
Arizona's attorney general is seeking to reopen the Ninth Circuit case as part of a broader state-level regulatory offensive that has simultaneously suspended Kalshi's operations in three states. This action occurs alongside the Sixth Circuit's two rulings against Kalshi, New Jersey's petition to the Supreme Court, and interim control victories by Ohio and Tennessee—creating a coordinated legal siege that contradicts Kalshi's federal preemption defense.
If the Supreme Court declines New Jersey's challenge or rules against Kalshi's own certiorari petition, the state-by-state litigation collapses into a resolved question favoring state regulation. Kalshi would likely lose access to the American prediction market altogether, transforming the regulatory siege from a litigation risk into a permanent business constraint across multiple jurisdictions simultaneously.
Investors in Kalshi's current funding round are pricing a Supreme Court reversal of the judicial trend favoring state regulation, betting that a single favorable ruling would grant Kalshi a federally protected monopoly position in a market that processed nearly twenty billion dollars in volume this year. This valuation assumes a litigation outcome that has not yet occurred, making the bet dependent on appeal-level reversals rather than current market conditions or operational metrics.
