Prediction market operator Kalshi announced the close of a $1 billion funding round, instantly valuing the company at $11 billion. This valuation reflects a doubling of the company's worth in less than sixty days, underscoring intense investor interest in event-based trading platforms. The financing round was led by returning investor Paradigm, with participation from established venture firms Sequoia Capital and Andreessen Horowitz.
Capital G also contributed to the round, alongside several other previous backers who reaffirmed their commitment to Kalshi's growth trajectory. This most recent investment follows a $300 million round announced just under two months ago, which placed Kalshi's valuation at $5 billion. Such rapid revaluation suggests substantial operational or market traction achieved during that short timeframe since the previous disclosure.
