1789 Capital Commits $300 Million to Polymarket Round Valuing Platform at $21 Billion
TL;DR — 1789 Capital is committing $300 million as part of Polymarket’s $1 billion round, lifting valuation from $15 billion to $21 billion. The firm’s stake, held for one year, has multiplied in value. The timing follows reports of Trump Jr. addressing regulatory matters at a Republican attorneys general event.
SCCG Take — Political connections tied to surging prediction-market valuations invite closer regulatory examination at state level. Participants must track legal challenges that could reshape institutional access.
Polymarket is raising another $1 billion, with Donald Trump Jr.’s venture firm 1789 Capital contributing $300 million. The transaction values the company at approximately $21 billion, up from $15 billion four months ago. 1789 Capital first took a stake one year ago, and that holding has multiplied in value alongside the platform’s rising worth.
Trump Jr. serves as an advisor to Polymarket and to another firm in the event contracts space. The latest capital infusion reflects continued institutional appetite for prediction market exposure.
Polymarket’s Sustained Fundraising in 2026
The company completed a separate $1 billion round in April. That earlier raise included $600 million from Intercontinental Exchange and $400 million from a group led by hedge fund D.E. Shaw. Polymarket has since relaunched its U.S. prediction market and is pursuing features aimed at professional traders, among them private-company contracts, GPU compute positions, and a filing seeking permission for margin trading.
Timing of the Increased Stake
The move by 1789 Capital follows by days a New York Times article citing unnamed sources that described Trump Jr. pressing Republican attorneys general to avoid state lawsuits targeting prediction markets. The reported remarks were made at the Republican Attorneys General Association conference in New Orleans. The association later told CNBC that the sources misconstrued the comments, which amounted only to a brief discussion of the regulatory landscape.
As reported by Casino.org News, the sequence is likely to raise eyebrows in some circles.
