Kalshi, the US-regulated prediction-market exchange, is raising fresh capital at a valuation of roughly US$40bn, according to trade reporting, close to double the figure it carried only weeks earlier. The round would extend a run of rapid re-ratings for a platform that lets users trade event contracts on real-world outcomes, from elections to sport.
The US$22bn benchmark the new round doubles was itself set recently. It came at a US$1bn Series F led by Coatue Management, with Sequoia Capital, Andreessen Horowitz and Morgan Stanley among the participants. Per TechCrunch, which reported the round on 7 May, that US$22bn valuation was itself a doubling in roughly five months. The latest raise could close as soon as the third quarter of 2026, according to the reporting, though the lead investor or investors in the new round have not been disclosed.
Chief executive Tarek Mansour has framed the momentum as the natural consequence of the company's trajectory, and has raised the prospect of a public listing. "A company of our financial profile with the rate of growth that we're seeing, that sort of conversation has to happen," Mansour said, in comments cited by trade coverage, having floated a potential 2027 initial public offering.
The fundraising also sharpens the contest at the top of the category. Rival Polymarket is reported to be seeking funding at around US$15bn, well below the mark Kalshi is now targeting. Driving the volumes behind the raise is a packed sporting calendar: the World Cup has supercharged trading, with Kalshi's June notional volume cited in trade coverage at about US$22.6bn, a figure the company has not formally confirmed.
A Doubling in Weeks Is a Bet on a Category, Not Just a Company
The most arresting fact here is the pace. A valuation that moved from US$22bn to a targeted US$40bn in a matter of weeks, having already doubled in the five months before that, is not a judgment on Kalshi's current earnings so much as a wager on where prediction markets are heading. Investors are pricing in the possibility that event contracts become a mainstream financial and quasi-betting product in the United States, with Kalshi as the regulated incumbent best placed to own it. That is a coherent thesis, but it is a directional one, and directional bets on nascent categories are the kind that re-rate downward just as quickly when the growth curve bends. The same velocity that makes the number look impressive is what should make a sober observer cautious about treating it as settled worth.
The World Cup Is Doing Some of the Heavy Lifting
Volume is the fuel for this valuation, and a large slice of it is arriving on the back of a single global event. A cited US$22.6bn in June notional trading is a striking number, but sport-driven volume is inherently lumpy: it swells around marquee tournaments and recedes between them. The strategic question for anyone underwriting a US$40bn price is how much of that activity persists once the World Cup is over and the calendar thins. If Kalshi can convert event-driven traders into habitual users across politics, economics and other verticals, the raise looks well judged. If June proves to be a peak inflated by a once-every-four-years spectacle, the volume comparison that helped justify the valuation becomes an awkward benchmark to lap.
The Valuation Is Racing Ahead of the Regulatory Settlement
What separates Kalshi from an ordinary high-growth exchange is that its core product sits on contested legal ground, where the boundary between a regulated event contract and a gambling wager is still being drawn. A US$40bn valuation implicitly assumes that boundary settles in Kalshi's favour, or at least does not move against it. That is a material assumption to fold into a price, because an adverse regulatory turn would not trim the growth rate at the margin; it could remove entire verticals from the addressable market overnight. Kalshi's status as a federally regulated exchange is its central asset and its central risk at once. The market is betting the asset outweighs the risk. Investors writing cheques at this level are pricing near-certainty on a question that is, by any fair reading, still open.
