Polymarket is discussing a $400 million funding round with potential investors.
The deal would value the prediction market platform at approximately $15 billion.
This financing follows a $600 million investment from Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange.
Total funding may reach $1 billion as the company seeks additional strategic investors.
The talks highlight a surge of institutional capital into the prediction market sector.
The industry faces increasing regulatory scrutiny despite explosive growth in trading volume.
