Polymarket Names Donald Trump Jr to Advisory Board

Polymarket has added Donald Trump Jr. to its advisory board following a new investment from 1789 Capital, a venture firm where Trump Jr. is a partner. The announcement confirmed the investment was at least eight figures, though exact terms were not disclosed.

Good to know

• Polymarket processed about $6 billion in prediction trades during the first half of 2025.
• The platform partnered with X (formerly Twitter) to serve as its official prediction market.
• Polymarket is preparing a U.S. return after acquiring QCX, a CFTC-licensed exchange, in a $112 million deal.

Polymarket allows users to buy and sell futures contracts on real-world events, including politics, cryptocurrency, and sports. Though the platform was banned in the U.S. in 2022 for operating without registration, it is preparing a regulated return by leveraging QCX’s license from the Commodity Futures Trading Commission (CFTC).

Company founder and CEO Shayne Coplan described the new investment as key to growth:

“This strategic investment marks a significant milestone for Polymarket. Our long-term partnership with 1789 Capital will help reinforce Polymarket’s leading position as a trusted source of free, transparent and accurate market information in the U.S. and around the world.”

Trump Jr. praised the platform for allowing users to voice their own predictions:

“Polymarket is the largest prediction market in the world, and the U.S. needs access to this important platform. Polymarket cuts through media spin and so-called ‘expert’ opinion by letting people bet on what they actually believe will happen in the world. I am pleased that 1789 Capital is investing in Polymarket and am honored to join the company’s advisory board.”

The move comes just months after Trump Jr. took on an advisory role with prediction market operator Kalshi, showing his growing involvement in the sector.

1789 Capital founder Omeed Malik also emphasized the firm’s support:

“1789 Capital looks to invest in companies that are entrepreneurial, innovative, and demonstrate great potential for growth. Polymarket meets each of these criteria. Polymarket stands at the intersection of free expression and financial innovation by empowering individuals with real-time truth in a world clouded by noise, and we are proud to support its vision.”
