Kalshi is in advanced talks to raise roughly $1 billion at a valuation of about $40 billion, potentially delivering another sharp repricing for the U.S. prediction-market operator only months after its previous funding round. The proposed financing would value Kalshi approximately 82% above the $22 billion valuation established in May. Reuters reported that existing investors Sequoia Capital and Wellington Management are discussing leading the round, with Tiger Global Management and Dragoneer Investment Group also considering participation.
The transaction is not yet complete, and its terms could still change. Reuters said the financing could close within weeks, while Kalshi and Tiger Global declined to comment and the other prospective investors did not respond. A $40 billion valuation therefore remains a reported funding target rather than an established market value from a completed transaction.
Trading Growth Drives Kalshi’s Valuation Push
Kalshi last raised $1 billion in May at a $22 billion valuation in a Series F led by Coatue. At the time, the company said its annualized trading volume had climbed from $52 billion to $178 billion over six months, while institutional volume increased 800%. Those figures form a central part of Kalshi’s growth case, but they are company-reported measures rather than independently audited indicators of sustained institutional demand.
CEO Tarek Mansour has argued that event contracts could become a trillion-dollar market, while Kalshi says it handles more than 90% of U.S. prediction-market activity. The company is also moving beyond conventional event contracts into broader derivatives. In May, the CFTC approved its Bitcoin perpetual futures contract, providing a regulated route into a product more commonly associated with offshore crypto exchanges. That expansion has also brought scrutiny over unusual trading patterns in Kalshi’s Ether perpetual market. Kalshi rejects claims that the repetitive trades demonstrate wash trading and says the patterns reflect liquidity incentives.
The strategy increasingly puts Kalshi alongside established derivatives infrastructure rather than limiting its competition to prediction-market platforms. Reuters reported that the company ultimately wants to compete across additional asset classes with operators including CME Group and Intercontinental Exchange. That institutional convergence is already visible elsewhere in the sector, including ICE’s $1.6 billion investment in Polymarket. Capital is increasingly flowing toward prediction markets as potential financial-market infrastructure rather than purely consumer forecasting products.
Regulatory Scrutiny Grows With Product Expansion
Kalshi has operated as a CFTC-designated contract market since 2020, and its federal regulatory status remains central to its U.S. strategy. That designation does not eliminate disputes over which event contracts can legally trade or whether federal commodities oversight preempts state gambling rules. Kalshi has already faced conflicting federal and state positions over sports-related contracts.
Market integrity is another growing issue. In May, the House Oversight Committee requested information from both Kalshi and Polymarket about identity verification, geographic controls and systems for detecting suspicious trading involving nonpublic information. The CFTC has separately warned that certain prediction contracts can carry heightened manipulation risks. Those inquiries concern the controls surrounding rapidly expanding event markets rather than establishing misconduct by Kalshi itself.
Reuters also reported that Kalshi has begun preliminary discussions about a future IPO, although no public filing or timetable has been announced. The immediate milestone is whether the proposed $1 billion financing closes near the reported $40 billion valuation. A completed round would establish the next private-market benchmark, while any eventual IPO filing would provide substantially more information about revenue, trading economics and the financial assumptions supporting that valuation.
