Prediction Markets Raise Like Exchanges: Kalshi Takes $1bn At A $40bn Valuation As Fintech Funding Hits $2.6bn In A Week

Prediction markets are now raising money like exchanges. Kalshi, the US exchange for event contracts, has raised about $1bn at a $40bn valuation, according to a Reuters report cited by FinTech Global on 29 October 2026, with Sequoia and Wellington leading and Tiger Global and Dragoneer taking part. That is nearly double the $22bn valuation of its previous $1bn round, led by Coatue in March, and it came a little over five months later.

The stated purpose is bigger than sport and elections. FinTech Global describes Kalshi as looking to "move past its prediction market origins and take on established trading venues", expanding into a platform that covers several asset classes. The round lifted that week's fintech total to more than $2.6bn across 19 deals, up from $541m the week before, with AI agent companies prominent among the rest.

Why Are Investors Valuing Prediction Markets Like Exchanges?

Because the business is turning into one. In the four weeks before the round, Kalshi signed a two-way benchmark deal with S&P Dow Jones Indices, under which S&P can build indices from Kalshi prices and Kalshi can list contracts settled on S&P values, and it filed for a WTI oil perpetual contract with the CFTC. S&P Dow Jones Indices chief executive Catherine Clay said indices "help to define markets: what they are, how to measure them and rules for monitoring their evolution".

The details show how early this still is. The S&P agreement names each side a preferred provider rather than an exclusive one, and no first indices, contract terms or launch dates have been disclosed. The proposed oil contract would track two nearby NYMEX WTI futures, settle in cash at 100 barrels a contract, a tenth of a standard oil future, and close at weekends like the futures it references. Kalshi filed it on 20 October; it cannot trade unless the CFTC approves it.

Each of those steps moves Kalshi closer to the established venues. The oil contract drew a letter from the Commodity Markets Council, whose members include CME, NYMEX and ICE Futures US, warning that "oil perpetuals threaten market integrity" and asking the CFTC to withhold approval. Investors putting in $1bn at $40bn are betting that Kalshi can keep winning those arguments.

The risks are also visible. FinTech Global notes that the funding news followed criminal charges filed by Utah's attorney general against Kalshi and two senior executives, alleging the firm unlawfully promoted online gambling. Kalshi describes itself as "the first regulated exchange dedicated to events". The gap between those two descriptions is the regulatory question every prediction market still has to answer state by state and country by country.

Where Did The Rest Of The Week's $2.6bn Go?

Much of it went to companies built around AI agents. FinTech Global's weekly round-up lists ten businesses in the week's deals that describe agents as central to their products, from cloud security to wealth management and finance operations. The chart shows the largest disclosed US dollar deals.

The agent theme is practical rather than speculative. Hyphenate, which raised a $45m Series A led by Nexus Venture Partners for what it calls autonomous finance, framed the opportunity simply: "Every finance team carries a long list of work it does because somebody has to." Nevis raised $70m led by EQT Ventures for AI in wealth management. On the trading side, the round-up also lists a $6m seed for Mochatrade, which offers tokenised US equities to traders in India.

Other large deals followed the same pattern of infrastructure over apps. Upwind's $400m Series C, led by Bessemer Venture Partners, is for cloud and AI security; PhotonPay's $40m Series C, led by Blockchain Capital, is for payments that combine stablecoins and traditional rails; and UK lender Lovey secured a facility of up to £250m from Pollen Street Capital. Numeracle's chief executive Rebekah Johnson summed up the security theme: "fraud and impersonation are not fundamentally communications problems, they are identity problems."

What Do Prediction Markets Mean For UK Brokers And Trading Firms?

For most UK firms, prediction markets matter first as a data source. Probabilities from Kalshi and its rivals are being packaged into indices and feeds, and clients will ask to see them beside prices. Offering the contracts themselves to UK retail clients is a separate and restricted question. The FCA has also flagged the integrity risk: its chief executive named insider trading linked to offshore gambling and prediction markets as a threat in his 22 October Mansion House speech, as we reported. Our September explainer sets out how these markets turn prices into probabilities and why the FCA is reviewing its approach.

Our View: The Money Is Following Market Structure, Not Hype

A $40bn valuation for a company founded in 2018 looks like exuberance until you list what it has built this year: a regulated exchange, an index partnership, a clearing-style ambition and a push into commodities. Investors are paying for the chance that event contracts become an asset class with the plumbing of an exchange. The opposition from CME and ICE suggests the incumbents take that chance seriously too.

The second signal is quieter but more relevant to most of our clients: when ten of the week's deals put AI agents at the centre of the product, the market is telling finance teams that routine work, reconciliations, reporting, client follow-ups, is going to be automated, and that buyers will expect controls and audit trails as standard.

“Investors are not paying $40bn for a betting app. They are paying for the chance that event contracts get the plumbing of an exchange, and the incumbents are behaving as if they agree.”

What It Means For Trading And Fintech Firms

• Brokers and CFD providers: plan for probability data next to prices. Licensing a feed or index is a different decision from offering contracts, and in the UK the second remains restricted for retail clients.
• Prop trading firms: decide whether event contracts or event-linked instruments are permitted, and how your rules treat positions around scheduled outcomes such as data releases and elections.
• Compliance leads: the FCA has linked prediction markets to insider dealing risk. If your firm displays or uses this data, record its source and who can see it.
• Finance and operations teams: the week's funding shows where agent tools are heading. Expect suppliers to pitch autonomous finance; ask them for limits, approvals and logs before features.
• Fintech and trading startups: the money is moving to market structure, indices, clearing, data and controls. Those layers need builders as much as the venues do.

The Bottom Line

Prediction markets are being financed like exchanges: Kalshi reportedly raised about $1bn at $40bn, up from $22bn in March, as it adds index partnerships and seeks to list an oil perpetual, while facing a criminal case in Utah. The same week's $2.6bn of fintech funding leaned heavily towards AI agents. AlchmAI, a London trading technology and AI studio, builds market data pipelines and AI workflow automation for trading and fintech firms, and both trends point to the same need: new data and new automation, delivered with the controls regulators expect.
