Polymarket’s valuation has surged to $21 billion after 1789 Capital, led by Donald Trump Jr., committed $300 million in a new $1 billion funding round, intensifying debate over federal and state oversight of prediction markets
Polymarket, a leading U.S. prediction market platform, has secured a $1 billion funding round led by 1789 Capital, the investment firm associated with Donald Trump Jr. The deal values Polymarket at approximately $21 billion, marking a significant increase from its earlier $15 billion valuation reported earlier this year. The latest investment highlights the growing institutional interest in event-based trading platforms as regulatory scrutiny intensifies.
Details of the Funding Round
According to sources familiar with the transaction, 1789 Capital is expected to contribute around $300 million to the new round, adding to the $200 million the firm has previously invested in Polymarket. This brings 1789 Capital’s total investment in the platform to roughly $500 million. The remaining $700 million is reportedly coming from a mix of institutional and private investors. The new valuation places Polymarket among the most highly valued prediction market operators globally, reflecting both user growth and increased attention from major financial backers.
Regulatory Tensions and Federal Oversight
The surge in Polymarket’s valuation comes as the regulatory environment for prediction markets remains unsettled. The Trump administration has publicly supported federal oversight of event contract platforms, with Michael Selig, the administration’s nominee to lead the Commodity Futures Trading Commission (CFTC), advocating for expanded CFTC authority. This position has put the federal government at odds with more than a dozen U.S. states, which have filed lawsuits against prediction market operators, especially over contracts tied to sporting events. State officials argue these products constitute gambling and should fall under state gaming laws, while federal authorities maintain that the CFTC should serve as the primary regulator.
Trump Jr.’s Expanding Role in Prediction Markets
Donald Trump Jr.’s involvement in the sector has grown since he joined 1789 Capital and accepted an advisory role at Polymarket. In 2025, he also became an adviser at Kalshi, another event contract platform, receiving equity valued at over $300,000. Trump Jr. has recently met with Republican state attorneys general to advocate for federal, rather than state, regulation of prediction markets. 1789 Capital has denied any conflicts of interest related to his dual roles. The firm’s portfolio now includes several high-profile private technology companies, with Polymarket representing its largest single exposure to the prediction market industry.
Market Growth and Ongoing Legal Disputes
Polymarket allows users to trade contracts on the outcomes of political, economic, entertainment, and sports events. The platform’s rapid growth has drawn both institutional traders and regulatory attention, especially as event contracts expand into sports-related markets. Ongoing legal disputes between prediction market operators and state authorities have created uncertainty for users and investors. The debate over whether these platforms should be regulated as gambling or as federally overseen event contract markets remains unresolved. Meanwhile, the sector’s expansion has prompted industry groups to consider voluntary standards for marketing and advertising, as seen in the Responsible Online Gaming Association’s recent introduction of a voluntary code for online gambling advertising.
Prediction markets operate by allowing users to buy and sell contracts based on the outcome of real-world events, with prices reflecting the perceived probability of those outcomes. In the U.S., the regulatory distinction between a prediction market and a traditional sportsbook is critical: while sportsbooks are typically licensed and regulated at the state level as gambling operators, prediction markets like Polymarket seek federal oversight as event contract markets under the CFTC. This legal and regulatory uncertainty affects both the availability of products to users and the long-term growth prospects for the sector.
