Kalshi, a leading event prediction platform, has secured over $300 million in a Series D funding round, bringing the company’s valuation to $5 billion, according to The New York Times. Prominent investors in the round include Sequoia Capital, Andreessen Horowitz, Paradigm, CapitalG, and Coinbase Ventures.
The new funding will allow Kalshi to expand its services to users in more than 140 countries, intensifying competition with rivals like Polymarket. The platform has experienced rapid growth, with annual trading volume approaching $50 billion and a global market share surpassing 60% in September, surpassing Polymarket in the process.
Kalshi’s growth has been driven by popular event-based contracts, including sports and multi-event bets, which have boosted user engagement. The company plans to scale its infrastructure and integrate with major digital asset platforms, aiming to become accessible through top financial apps such as Robinhood and Webull.
While expanding internationally, Kalshi remains committed to regulatory compliance. In May 2025, the Commodity Futures Trading Commission (CFTC) dropped a lawsuit regarding election-related contracts, though several states continue to examine sports betting offerings under gambling regulations.
With this Series D round, Kalshi emerges as one of the highest-valued platforms in the prediction market segment. Its previous Series C round raised $185 million at a $2 billion valuation.
The company also recently announced a partnership with AI firm xAI, further enhancing its market presence and product offerings.
