Polymarket chases $20 billion valuation, narrows gap with prediction market rival Kalshi

Polymarket is hunting for fresh capital at a valuation that could exceed $20 billion, according to recent reports. The move comes less than four months after the platform closed a $1 billion raise at $15 billion, and it signals aggressive expansion in the booming prediction markets space.

The jump matters because it would nearly double Polymarket's October 2025 valuation of $9 billion. More importantly, it closes ground on Kalshi, which hit $22 billion after its May funding round. The two platforms are now locked in a race to dominate regulated betting on elections, sports, and world events.

Revenue and trading volume surge post-launch

Polymarket's numbers are moving fast. After launching its regulated U.S. exchange, annualized revenue has jumped above $1.2 billion, nearly triple the April level. The U.S. platform alone now processes over $100 million in daily notional trading volume, up from around $75 million in late May. Its international platform handles another $150 million daily.

The April round itself was substantial. Polymarket raised $1 billion from a lineup that included D.E. Shaw and G Squared, alongside existing backers like SV Angel and Dragonfly. Intercontinental Exchange, which owns the New York Stock Exchange, also kicked in a previously announced $600 million direct investment, signaling Wall Street's confidence in the space.

Competition heating up

Prediction markets caught fire during major events. Trading accelerated sharply during the FIFA World Cup in June and July, showing how these platforms tap into real-world interest. Kalshi's $22 billion valuation proves the market believes this category can scale far beyond niche betting.

If Polymarket closes its reported $20 billion round, the company would have raised roughly $2.6 billion in six months. That pace of capital deployment suggests investors see prediction markets as a genuine alternative to traditional polling and forecasting, not just a crypto novelty.
