Prediction-market startup Kalshi announced a $1 billion [1] Series F financing round on Thursday that values the company at $22 billion [1].

The rapid increase in valuation highlights the growing institutional appetite for event-based trading platforms. As these markets gain mainstream traction, Kalshi's ability to attract massive capital suggests a shift in how investors view the scalability of prediction markets.

This latest valuation is roughly double the $11 billion [1] mark the company reached five months earlier. The current round was led by Coatue [1].

Kalshi reported an annualized trading volume of $178 billion [2]. The company said it intends to use the new capital to fund continued growth as it expands its footprint in the financial technology sector.

The startup's trajectory has been steep over the last year. While the company reached an $11 billion valuation around December 2025 [1], reports from late 2025 indicated a previous $1 billion fundraise led by Sequoia and CapitalG [2]. Earlier in October 2025, the company had hit a $5 billion valuation [1].

This sequence of funding rounds demonstrates a compressed timeline of growth. By securing another $1 billion [1] in May 2026, Kalshi has positioned itself as a dominant player in the niche of forecasting markets, platforms where users trade on the outcome of real-world events.

The surge in Kalshi's valuation reflects a broader trend of financialization in forecasting. By moving from a $5 billion valuation in October 2025 to $22 billion by May 2026, the company is signaling that prediction markets are transitioning from niche betting tools to significant financial instruments capable of processing hundreds of billions in volume.
