Kalshi and Polymarket, two leading prediction market platforms, are exploring fundraising rounds that could each value the companies at $20 billion, roughly double their last valuations, according to the Wall Street Journal.
Kalshi’s most recent funding round in December 2025 valued the company at about $11 billion after raising $1 billion from investors, including Sequoia Capital and CapitalG.Â

Polymarket was valued at approximately $9 billion in October 2025 following a significant investment agreement with the Intercontinental Exchange, the parent of the NYSE.
Trading Volumes Surge
Prediction markets allow users to trade on outcomes of events, from elections to economic indicators, offering an alternative to traditional financial speculation.
The fundraising talks reflect rapid expansion in trading activity. Combined monthly trading volumes across both platforms reached about $18.3 billion in February 2026, up sharply from under $2 billion in August 2025.
Kalshi alone has crossed a $1 billion annualized revenue run rate, with some estimates placing it closer to $1.5 billion.
Regulatory Pressure Grows
The push for larger valuations comes amid increasing political and regulatory scrutiny. U.S. lawmakers have proposed measures to limit certain types of prediction markets, including those tied to war or sports events.
Both Kalshi and Polymarket have also faced controversy over controversial contracts and accusations of aggressive promotional practices.
Polymarket is preparing to fully launch a regulated U.S. version of its platform this year, expanding access beyond its current restrictions for U.S. users.
Why This Matters
High valuations for Kalshi and Polymarket reflect strong revenue growth expectations and could influence users, partners, and talent, highlighting the growing mainstream relevance of prediction markets.
