Kalshi raises $1 billion, doubling valuation to $11 billion amid rapid industry expansion
Summary
Prediction market operator Kalshi has closed a $1 billion funding round that pushes its valuation to $11 billion, coming less than two months after a $300 million raise at a $5 billion valuation. Returning investors such as Sequoia and CapitalG joined new and existing backers including Andreessen Horowitz, Paradigm, Anthos Capital and Neo.
The raise occurs as event-based trading platforms gain traction worldwide. Kalshi now serves users in more than 140 countries, with official trackers showing cumulative trading volume above $17 billion and over 68.4 million transactions. Competitors Polymarket and Opinion are also posting very high weekly volumes, underlining a fiercely competitive market. Google Finance has begun integrating real-time data from both Kalshi and Polymarket, increasing mainstream visibility.
Kalshi operates as a Designated Contract Market under CFTC regulation, but it continues to face state-level legal challenges: lawsuits and injunction disputes are underway in Massachusetts, Nevada, Maryland and New York, particularly around sports-related prediction products.
