Investment Firm 1789 Capital has invested a double-digit million dollar sum in prediction platform Polymarket, with Donald Trump Jr. joining the company’s advisory board. This strategic move positions Trump Jr. further within the rapidly growing predictions space. A recent Axios report highlights that Founders Fund valued Polymarket at over $1 billion after its entry into the U.S. market. The investment comes after the company acquired derivatives exchange QCEX for $112 million, securing a coveted CFTC license during this process. 1789 Capital’s involvement follows Trump Jr.’s own excitement about this deal; he expressed his pride on Twitter: ‘Pleased to announce that my fund @1789capital has invested in @Polymarket and that I will be joining the team as a Strategic Advisor.’. The company’s expansion is driven by prediction market technology, which has become an innovative way for people to follow news events. Trump Jr.’s investment signifies growing institutional confidence in Polymarket’s potential as a legitimate financial instrument. Investigations into Polymarket are concluding with no evidence of wrongdoing from the company. The recent acquisition of QCEX further solidified their U.S. entry, enabling regulated access to American users. With over $6 billion in predictions made so far in 2025 and a significant portion being placed on last year’s Trump-Harris election, Polymarket has shown strong performance in the industry. The company also plans to introduce American users back into the platform through their partnership with QCEX. 1789 Capital’s expertise in successful companies like Anduril and SpaceX suggests Polymarket as a promising IPO candidate. With his advisory roles at both Polymarket and Kalshi, Trump Jr. sits at the center of an industry poised for mainstream adoption.
