Polymarket reportedly raises $300M from Donald Trump Jr.’s investment fund

Polymarket has reportedly raised $300 million from 1789 Capital, according to TechCrunch, citing The Wall Street Journal’s report based on unnamed sources. The investment is described as part of a new funding round expected to total around $1 billion.

1789 Capital is an investment fund where Donald Trump Jr. is a partner. TechCrunch also notes that the firm previously invested $200 million in the prediction site.

The funding is notable not only for its reported size, but also because of 1789 Capital’s existing connection to Polymarket. TechCrunch reports the firm has backed other controversial tech-related projects, including the Enhanced Games.

For readers tracking startup fundraising, the key takeaway is that prediction-market companies continue attracting major capital even as questions over oversight remain unsettled.

Prediction markets are facing increased regulatory scrutiny, with many state governments seeking new rules around whether and how residents can use the sites. TechCrunch reports that at least 20 states are engaged in litigation against prediction sites over sports wagers offered on those platforms.

The federal-state divide is a major issue for the sector. The Trump administration has argued that the Commodity Futures Trading Commission should be the sole regulator of the industry, while a coalition of 44 state attorneys general recently argued that the CFTC lacks authority over sports-related wagers on prediction sites.

TechCrunch says it reached out to Polymarket for comment, so confirmation or further details from the company remain important. Readers should watch for any additional disclosures about the final size of the round, investor participation, and how the company addresses regulatory questions.

The bigger implication is clear: funding momentum and legal uncertainty are moving in parallel for prediction markets. That tension may shape how platforms grow, where they operate, and which regulators ultimately set the rules.
