Kalshi's $40bn round asks investors to price growth and a legal fight at the same time

The prediction market nearly doubled its valuation in five months, a day after Utah charged its founders. Its backers are betting that federal law, not state courts, will set its ceiling.

Kalshi, the New York prediction market operator, said on October 29th that it had raised $1bn in a Series G round at a post-money valuation of $40bn. Wellington and Sequoia co-led the round, joined by Baillie Gifford, Andreessen Horowitz, Coatue, CapitalG, Morgan Stanley Investment Management, Hudson River Trading, Balyasny Asset Management, Stripes, Layer Global and Sequoia Global Equities. The price is roughly 82% above the $22bn at which Coatue led a $1bn Series F in May, and about eight times the $5bn figure CNBC attached to the company a year ago.

The timing is what makes the deal worth more than a line in the weekly league tables. The day before the announcement, prosecutors in Utah filed 14 criminal counts against Kalshi and its co-founders, Tarek Mansour and Luana Lopes Lara. A day before that, the Commodity Futures Trading Commission sued Utah to stop it. It is rare for a round of this size to close while the issuer's founders face state felony charges. That the investor list is dominated by crossover and public-market institutions rather than early-stage specialists tells you how the round is being underwritten: as a pre-listing position in a would-be exchange, with the legal risk treated as a known quantity.

What the money buys

Kalshi's own account of the round leans heavily on metrics designed to show it is no longer a sports-betting proxy. The company says it now runs at more than $1tn in annualised trading volume across all products, has seen over 30 million accounts created and handles more than three-quarters of prediction market volume. It puts non-sports annualised revenue above $1bn. Commodities contracts, it says, reached over $100m in annualised fees within three months of launch; crypto contracts run at $140bn of annualised volume; perpetual futures have drawn $83bn of volume and more than 500,000 traders since launching a few months ago. About 500 institutional entities were active in September, and those other than market makers accounted for roughly a quarter of exchange volume.

These are company figures and have not been independently audited. Their selection matters as much as their size. By emphasising non-sports revenue, Kalshi is answering the question that every state attorney general is asking: strip out the football and what is left? The new capital is earmarked for institutional sales and products aimed at hedge funds and proprietary trading firms, for expansion in Latin America and Europe, and for three new product lines: indices built with S&P, single-stock perpetual futures and markets in computing capacity. Taken together, the roadmap describes a derivatives exchange that happens to have started with event contracts, which is a far easier business to defend before a federal judge.

The pace of the mark-ups

The arithmetic of Kalshi's recent fundraising is striking even by the standards of an AI-inflated private market. According to Cooley, which advised on the May deal, the company raised a $300m Series D in October 2025 and a $1bn Series E in December 2025 before the Series F. Adding the latest round, that is $3.3bn in priced equity across four rounds in roughly 12 months, with the valuation compounding at each step.

Rapid serial rounds at rising prices are usually a sign that insiders want to keep ownership as the company approaches a public listing. The New York Times reported that the Series G is widely expected to be Kalshi's last private round before an initial public offering, though Mr Mansour declined to say whether or when one would happen, saying only that there had been discussions. The presence of Wellington, Baillie Gifford and Morgan Stanley's investment arm fits that reading: these are investors that like to own a position before the order book opens.

The round also landed in a busy week. Crunchbase's ranking of the largest American rounds for October 24th to 30th, as summarised by Tech Insider, placed Kalshi second behind the $2.1bn raised by the manufacturing group Re:Build, ahead of Bedrock Robotics' $600m Series C at $4.1bn. Among the ten, Kalshi's was the only disclosed valuation above $5bn.

The Utah problem

The charges in Salt Lake City are more serious than the usual state cease-and-desist letter. According to the Deseret News, they comprise one count of a pattern of unlawful activity, a second-degree felony; 12 counts of online gambling promotion, each a third-degree felony; and one misdemeanour count of gambling promotion. They rest on an undercover investigator who opened an account in September and placed about a dozen bets on professional and college sports over 11 days. Utah had already filed a civil suit the previous week seeking to halt Kalshi's operations in the state and recover profits it estimates at between $30.5m and $61.1m.

Utah also holds a stronger hand than most states. In August, a federal judge in Kalshi's own suit against Utah ruled that the state's anti-gambling laws apply to its sports contracts and that federal law does not preempt them. Kalshi called the criminal case a "crazy overreach" and said it would fight it, as it did in Arizona, where a federal judge enjoined an earlier criminal prosecution that the state is now appealing.

The federal government is on Kalshi's side. The CFTC's complaint seeks declaratory and injunctive relief to stop Utah using state law to shut down federally registered contract markets. The agency says it has now brought proceedings against nine other states and filed briefs in four federal appeals courts. Its chairman, Michael Selig, said Congress had entrusted the CFTC to be the sole regulator of these markets. Reporting by CNBC, cited by RG, notes that two federal appeals courts have ruled that states can regulate sports event contracts and a third has held the opposite, a split that points towards the Supreme Court.

How the valuation absorbs the risk

The simplest way to read a $40bn price struck amid felony charges is that investors assign a high probability to federal preemption ultimately prevailing, and a tolerable cost to the scenario in which it does not. The non-sports revenue figure is the hedge. If states win the right to police sports contracts, Kalshi loses some of its most popular markets in some jurisdictions but keeps an exchange business in commodities, crypto, indices and perpetuals that, on its own numbers, already generates more than $1bn a year. Backers are effectively paying for that floor and treating the sports franchise as an option.

That logic has limits. A public offering requires disclosure of litigation exposure in a form that private term sheets do not, and criminal cases against named executives sit awkwardly in a risk-factors section. An adverse Supreme Court ruling would not merely shrink one product line; it would invite every state to bring its own case, raising compliance costs across the business. The valuation also relies on a federal regulator whose current enthusiasm for prediction markets is a policy choice that a future administration could revisit.

Our view

Kalshi's round is less a bet on prediction markets than a bet on jurisdiction. The investors writing the largest cheques are not naive about the legal exposure; they have concluded that the company's federal registration and its diversification into conventional derivatives make it the likeliest survivor of a fight that will be settled in Washington rather than Salt Lake City. That may prove right, but it means the equity is now unusually sensitive to a single legal question that no amount of product growth can answer. For founders in regulated categories, the lesson is that capital will follow a credible federal licence even through state hostility, provided the business can show revenue that does not depend on the contested activity. For investors, the things to watch are the Supreme Court's docket, any criminal court dates in Utah and the first sign of an IPO filing, when Kalshi will have to quantify in public the risks its private backers have so far priced in private.
