Prediction market exchange Kalshi announced on Thursday that it has completed a $1 billion funding round, bringing its valuation to $40 billion. The milestone follows a previous funding round in May that valued the company at $22 billion.
Growth Drivers and Legal Challenges
According to the company, the latest financing round was co-led by Sequoia Capital and Wellington Management. Kalshi experienced continued growth in its prediction markets since the prior funding round, propelled by events such as the 2026 FIFA World Cup, the NFL season, and increased trading on election markets ahead of the U.S. midterms. Both sports events triggered explosive growth in combo contracts, which function similarly to parlays on sportsbooks.
During the same period, Kalshi encountered legal hurdles concerning its sports offerings. Two U.S. appeals courts issued rulings in August and September determining that individual states possess the authority to regulate sports-related event contracts. Conversely, Kalshi and competing prediction market platforms maintain that federal regulation applies. Because a third appeals court ruled in favor of the federal argument, a Supreme Court case is expected to resolve the disagreement.
Expansion Plans and Public Market Considerations
In late May, Kalshi launched perpetual futures as its first non-prediction market offering, marking the first time the popular cryptocurrency trade came to a U.S. exchange.
Kalshi stated in a blog post that prediction markets represent only the beginning of its ambition to construct a broader financial exchange. The platform plans to allocate the fresh capital toward developing leveraged event contracts, perpetual futures tied to individual stocks, and markets for trading compute prices. Additionally, the company intends to invest further in its institutional business, noting that it worked with 500 institutional entities in September, which accounted for 25% of total trading volume excluding market makers.
The private market valuation has surged rapidly, up from a $5 billion valuation in October 2025. Speaking on CNBC’s “Squawk Box” in June, CEO Tarek Mansour mentioned that the company was evaluating a transition to public markets, likely by 2027.
“A company of our financial profile with the rate of growth that we’re seeing, that sort of conversation has to happen,” Mansour said.
