Polymarket Eyes $15B Valuation in $400M Fundraise
Prediction market Polymarket is in talks to raise $400M at roughly $15B, still trailing rival Kalshi's $22B valuation.
Polymarket is gunning for fresh cash. The prediction market platform is in discussions with investors to raise $400 million at a post-money valuation of approximately $15 billion, according to The Information.
That's a solid jump from its $9 billion valuation in October 2025 — nearly doubling in a matter of months. But it still leaves Polymarket in second place behind rival Kalshi, which notched a $22 billion valuation back in March 2026.
The prediction market space has been heating up fast, with both platforms racing to capture growing demand for event-based trading. Polymarket's new round would give it significant runway to compete, though Kalshi's valuation lead of $7 billion is hard to ignore.
The round hasn't closed yet, so final terms could still shift.
