    Kalshi Discloses $1.12 Billion Raise as SEC Filing Points Toward $40 Billion Valuation

    A regulatory filing posted Tuesday with the U.S. Securities and Exchange Commission confirms what the prediction market industry has been watching all summer: Kalshi has absorbed more than a billion dollars in private equity since April, and the company appears to be positioning for a valuation nearly double the $22 billion it carried just three months ago.

    The Form D—a standard SEC disclosure used for private securities offerings—shows Kalshi has sold $1,120,010,122 in equity under a $1,499,997,894 offering that started on April 3, 2026. Seventy-one investors have participated. Roughly $380 million remains available under the same notice. CEO Tarek Mansour authorized the filing.

    That combination of numbers tells a story: more than three-quarters of a $1.5 billion offering closed in less than five months, leaving a window that could accommodate the additional $750 million raise that The Information reported Kalshi was pursuing at a $40 billion valuation. Or not—the Form D does not break down which financing rounds contributed to the $1.12 billion figure, or whether the remaining $380 million relates to a new round at the higher price.

    What the SEC Filing Actually Shows

    Form D filings are required under Regulation D when companies sell securities through private placement exemptions—in this case, Rule 506(b). They disclose the size of the offering, how much has been sold, when the first sale occurred, and who authorized the filing. They deliberately omit investor names, individual transaction sizes, and the valuation per share.

    What the Kalshi filing confirms directly:

    • Offering amount: $1,499,997,894
    • Amount sold: $1,120,010,122
    • Date of first sale: April 3, 2026
    • Number of investors: 71
    • Exemption: Rule 506(b), Regulation D
    • Filing date: August 25, 2026
    • Authorized by: Tarek Mansour (CEO)
    • Directors listed: Tarek Mansour, Luana Lopes Lara, Alfred Lin, Michael Seibel, Matt Huang

    The filing notes no sales commissions or finder's fees and establishes no minimum investment threshold.

    One key uncertainty remains: whether the $1.12 billion figure includes Kalshi's $1 billion Series F, which was announced in May 2026 and led by Coatue with participation from Sequoia Capital, Andreessen Horowitz, IVP, Paradigm, Morgan Stanley, and ARK Invest. The Form D does not distinguish between financing rounds within the same notice, so the relationship between the two transactions remains ambiguous.

    A Valuation in Fast-Forward

    The backdrop to this Form D is one of the most compressed valuation trajectories in recent private-market history.

    Kalshi's approximate valuation progression:

    • ~$2 billion — mid-2025
    • ~$5 billion — late 2025
    • ~$11 billion — early 2026
    • $22 billion — May 2026, Series F (Coatue-led)
    • $40 billion — proposed, per The Information (August 13, 2026)

    That is roughly a 20× increase in approximately one year. Each jump corresponded to a concrete catalyst: exchange volume milestones, sports market launches, institutional trading desk adoption, and most recently the 2026 FIFA World Cup, which drove record-breaking activity across the platform.

    In June 2026, the Financial Times reported that Kalshi was exploring a new funding round at a $40 billion valuation and that the financing could close as early as the third quarter of the year. On August 13, The Information reported that those talks had advanced, with Sequoia Capital and Wellington Management in discussions to serve as co-lead investors in a round of at least $750 million.

    Wellington Management—which manages approximately $1.3 trillion in assets—would be making its first investment in Kalshi. Wellington has a pattern of taking pre-IPO positions in high-growth financial companies. Sequoia, already a board-level investor through director Alfred Lin, would be deepening an existing position it has held through multiple rounds.

    The Operating Numbers Behind the Raise

    Private fundraising at this scale does not happen on narrative alone. Kalshi has backed its valuation progression with operating metrics that, if accurate, make the numbers at least partially explicable.

    According to reporting from The Information and Financial Times citing sources familiar with the company:

    • Annualized revenue: Approximately $4 billion as of July 2026, driven largely by sports contracts tied to the 2026 World Cup
    • Monthly trading volume: $40 billion in July 2026, compared to a combined $12.9 billion across Polymarket and Polymarket US in the same period
    • Annualized trading volume: Approximately $178 billion as of April 2026, up from roughly $5 billion a year earlier
    • US market share: Kalshi claims approximately 95% of U.S. prediction market volume by revenue
    • Employee count: Approximately 525 as of mid-2026

    Sports contracts—particularly around the FIFA World Cup and NFL regular-season markets—account for more than 80% of Kalshi's trading activity. The platform's expansion beyond traditional event contracts, including CFTC-approved spot bitcoin perpetual futures launched in May 2026, has added volume diversification.

    At an annualized revenue of $4 billion, a $40 billion valuation implies a price-to-revenue multiple of roughly 10×. For comparison, the New York Stock Exchange's parent ICE traded at approximately 12× revenue at similar growth stages. The multiple is aggressive but not disconnected from precedent for regulated financial infrastructure with demonstrated network effects and high switching costs.

    The IPO Track

    Wellington Management's pattern of taking pre-IPO positions is not accidental context. CEO Tarek Mansour said publicly in June 2026 that Kalshi is evaluating an initial public offering as early as 2027. The Information also reported that Kalshi held early-stage discussions with investment banks regarding a potential public listing and strategic partnerships with institutional clients.

    A Kalshi IPO at or near a $40 billion valuation would represent a significant milestone for the prediction market industry. The company would become the first CFTC-designated contract market to reach public markets, establishing a formal comparable for every other regulated platform in the space.

    No IPO prospectus or S-1 has been filed. A 2027 timeline remains unconfirmed and subject to market conditions, the outcome of ongoing state-level litigation, and the completion of any pending financing rounds.

    What the Fundraise Means for the Broader Industry

    Kalshi occupying a $40 billion valuation—if the round closes—would do more than mark a company milestone. It would set a public benchmark for how institutional capital is pricing regulated event-contract markets generally.

    Polymarket, the global prediction market platform and the operator of QCX LLC (its U.S. CFTC-regulated venue), has been separately reported to be seeking funding at a $20 billion valuation—roughly half the Kalshi figure. That gap reflects not just platform size differences but regulatory positioning: Kalshi operates as a CFTC DCM and DCO with broad market coverage, while QCX LLC's current approvals limit it to sports markets for U.S. users.

    The Form D also arrives during sustained legal pressure. Multiple states—including Washington, Utah, Michigan, and New York—have challenged Kalshi's operations under state gambling laws, and several court decisions have gone against the platform. The company's legal costs and lobbying activities represent material headwinds that institutional investors are presumably pricing in.

    At the same time, the CFTC under Chair Michael Selig has consistently defended the regulatory framework allowing Kalshi to operate, and the CLARITY Act—if it advances through the Senate—would further entrench federal preemption over state gambling law for regulated event-contract markets.

    For traders and market observers, the practical conclusion is clear: the institutional money flowing into this space is not retreating. It is accelerating.

    Frequently Asked Questions

    What is a Form D filing? Form D is a notice filed with the SEC when a company sells securities through a private placement exemption from full registration. It discloses offering size, amount sold, date of first sale, and number of investors—but not individual transaction terms or investor names.

    Does the Form D confirm the $40 billion valuation? No. The filing reports the amount of equity sold and remaining under the offering, but does not disclose the valuation per share or the terms of any new round. The $40 billion figure comes from separate reporting by The Information and the Financial Times, citing sources familiar with ongoing negotiations.

    What is Kalshi's current regulatory status? Kalshi is a CFTC-designated contract market (DCM) and designated clearing organization (DCO). It operates as a fully regulated derivatives exchange under federal commodities law.

    Is Kalshi available in all 50 states? As of August 2026, Kalshi has faced geofencing orders in Washington state and Nevada and is navigating court rulings in several other jurisdictions. Availability varies by state—check Kalshi's official platform for current access restrictions.

    What does this mean for other prediction market platforms? A closed round near $40 billion would establish a valuation anchor for the broader sector and could accelerate institutional attention to other CFTC-regulated platforms, including ProphetX, Novig, and the growing infrastructure layer of licensed entities.

    Conclusion

    A Form D is disclosure, not announcement. Kalshi's August 25 filing does not confirm a closed round, does not name investors, and does not resolve the relationship between the $1.12 billion already raised and the $750 million round reportedly in negotiation. What it does provide is the clearest public signal yet of the scale of private capital flowing into the prediction market leader—and the pace at which that capital has moved.

    Whether the $40 billion round closes this quarter or slips into 2027, the trajectory is on the record. Kalshi began 2025 valued at roughly $2 billion. It may enter 2027 as a public company valued at 20× that figure. Event-contract markets, once a regulatory curiosity, are now the subject of serious institutional underwriting.
