Polymarket says its annualized revenue has surpassed $1.8 billion as activity on its US prediction market exchange continues to rise.
The figure is well above the annual revenue run rate of more than $1 billion disclosed in June, shortly after the company launched its domestic exchange in May. That venue operates separately from Polymarket’s international decentralized finance platform.
Notional volume on the US exchange reached more than $14.5 billion in October, compared with around $4 billion in June.
Sports markets have contributed heavily to that increase. Trading accelerated during the FIFA World Cup and remained strong after the NFL season began in September. College football also added activity.
Polymarket’s Combo event contracts have become another significant source of volume. The product allows customers to combine several outcomes into one position and accounted for more than 70% of platform volume on Sunday.
US Exchange Supports Revenue Growth
The US platform has become an important part of Polymarket’s business since its May 2026 launch.
The rise from about $4 billion in June notional volume to more than $14.5 billion in October shows how quickly trading activity increased during the second half of the year.
The $1.8 billion figure represents annualized revenue based on the company’s current pace rather than revenue already earned over a full year.
Growth has coincided with further fundraising. According to CNBC, Polymarket began seeking $1 billion in fresh capital in August at a reported valuation of $21 billion.
The supplied material also cites investment from Donald Trump Jr.’s venture capital firm 1789 Capital, Intercontinental Exchange and a consortium led by D.E. Shaw.
Polymarket remains privately held.
Regulatory Pressure Continues
The company is also facing scrutiny from US regulators.
The Commodity Futures Trading Commission is investigating Polymarket’s advertising practices and whether the company previously violated a 2022 settlement requiring it to prevent US residents from accessing its international platform.
Its domestic exchange now provides a separate US venue, while questions about its earlier operations remain under review.
Polymarket has said it is willing to engage with lawmakers as political attention around prediction markets increases.
“We welcome scrutiny,” a spokesperson said.
Further congressional attention could follow the midterm elections, particularly because Donald Trump Jr. serves as an adviser to the company.
Sports event contracts also remain part of a wider legal debate. The NFL has backed New Jersey in litigation involving prediction markets, arguing that such contracts should be treated as gambling rather than financial swaps.
The possibility of eventual US Supreme Court involvement remains unresolved.
Polymarket enters the final weeks of 2026 with trading activity well above levels seen earlier in the year.
Its annualized revenue has climbed from more than $1 billion in June to above $1.8 billion, while October US notional volume exceeded $14.5 billion.
