Polymarket in talks for new investment at US$15 billion valuation

The new deal brings the prediction market startup's value up from US$9 billion last year, when Intercontinental Exchange Inc. (ICE), the parent company of the New York Stock Exchange, took a US$1 billion stake in Polymarket in a blockbuster deal. Polymarket, though, is now worth less than the US$22 billion valuation that its main rival, Kalshi Inc., fetched in a recent US$1 billion fundraising round.
