Kalshi Secures $300M Funding, Valuation Soars to $5B Amid Prediction Market Boom

Prediction market platform Kalshi has closed a $300 million funding round, catapulting its valuation to $5 billion. The raise, backed by Sequoia Capital, Andreessen Horowitz, and Coinbase Ventures, signals strong institutional confidence in speculative markets tied to real-world events.

Trading volume on Kalshi now exceeds $1 billion weekly—a threefold increase year-over-year. The platform dominates over 50% of the prediction market sector after expanding to 140 countries and diversifying into sports contracts like NFL betting.

The funding aligns with broader momentum in event-driven trading platforms. Polymarket and IREN Ltd. also secured major investments this week, collectively raising nearly $3 billion. These platforms are bridging decentralized finance with traditional speculative markets.
