Polymarket annualised revenue tops $1.8bn as combo bets drive surge

Polymarket told CNBC on Tuesday that its annualised revenue has exceeded $1.8 billion, up from more than $1 billion in June, as monthly trading volume on its US exchange climbed to $14.77 billion in October from $4.04 billion in June — a 266% increase over five months.

Combo contracts, which bundle multiple predictions into a single bet, accounted for $8.6 billion of October's volume. Sports contracts contributed $4.57 billion. Political markets, despite a midterm-election spike in the first ten days of November, represented just 2.2% of November trading volume.

The growth tracks the platform's US relaunch. Polymarket began admitting American traders to a separate domestic exchange in late 2025, three years after a CFTC settlement had blocked US access to its international platform.

The company is raising $1 billion at a reported $21 billion post-money valuation. 1789 Capital, where Donald Trump Jr. is a partner, is reportedly leading the round with approximately $300 million.

The CFTC has been investigating Polymarket. Two US senators separately called on the regulator in June to examine allegations the company paid influencers to promote its platform.
