1789 Capital, linked to Trump Jr., reportedly leads Polymarket’s $1B round

Polymarket is reportedly preparing a major new funding push that would significantly deepen its backing from politically connected capital. According to the Wall Street Journal, 1789 Capital—where Donald Trump Jr. is a partner—is set to invest around $300 million in the blockchain-based prediction market as part of a broader $1 billion fundraising round.

The same report says the round could value Polymarket at $21 billion. If it closes as described, 1789 Capital’s participation would be large enough to move the firm into one of Polymarket’s most prominent investors.

Key takeaways

• 1789 Capital is reportedly planning an approximately $300 million investment in Polymarket within a $1 billion round.
• The reported round would value Polymarket at about $21 billion, potentially reshaping the company’s investor cap table.
• ICE is still Polymarket’s largest disclosed investor, with $1.6 billion invested in preferred shares reported in an ICE 10-Q filing.
• Polymarket’s fundraising momentum is unfolding amid growing US and international regulatory pressure on prediction markets.

What 1789 Capital’s reported entry could mean

Money matters in prediction markets because it funds liquidity, infrastructure, and the ability to scale participation across event categories. A $300 million commitment—if confirmed—would represent a substantial injection of risk capital at a time when the sector is trying to expand while regulators scrutinize how these markets function.

The Wall Street Journal report also indicates that 1789 Capital is already invested in Polymarket, bringing its total exposure to about $500 million. That would position the firm among Polymarket’s largest backers once the additional investment is completed, potentially increasing its influence in governance discussions that often accompany major rounds.

Cointelegraph says it reached out to both 1789 Capital and Polymarket for comment, according to the article text provided.

Valuation questions and how the funding fits prior fundraising efforts

Polymarket’s reported funding strategy appears to be evolving alongside competition in US prediction-market offerings. Earlier coverage cited in the source notes that Polymarket reportedly began talks in April to raise $400 million at a potential $15 billion valuation—lower than the valuation of Kalshi, Polymarket’s main competitor at the time, which was referenced at $22 billion.

By contrast, the new reported valuation in the Wall Street Journal—$21 billion—would reflect a different pricing environment than the earlier fundraising attempt. Whether that shift signals improved traction, investor sentiment, or simply negotiation dynamics remains unclear from the provided information, but the reported numbers suggest Polymarket is aiming for a materially higher valuation than what it sought months earlier.

Investors watching similar rounds often focus on whether valuation increases coincide with clearer compliance pathways or deeper liquidity partnerships—especially in a sector where regulatory outcomes can change quickly.

ICE’s disclosed stake highlights how concentrated backing is

Even with new entrants, Polymarket’s ownership remains dominated by large institutional investors. In a July 30 10-Q filing, ICE reported that it invested a combined $1.6 billion in Polymarket preferred shares.

ICE’s filing further states that the holdings had a carrying value of approximately $2 billion as of June 30. It also says the preferred shares represented about 22% of outstanding shares, or 14% on a fully diluted basis.

These figures illustrate a key structural point for readers: while new capital can increase the total funding available to Polymarket, the largest disclosed backer—ICE—already holds a significant portion of equity-linked exposure. Any incoming round will likely be interpreted against that backdrop, particularly when assessing how much ownership and control different investors retain after issuance.

Regulatory pressure remains the central risk as capital seeks a path forward

The funding headlines arrive during a period of intensified scrutiny of prediction markets. The provided source recounts that on Aug. 14, JPMorgan Chase reportedly ended a banking relationship with Polymarket over regulatory concerns, though it said it remains interested in potentially providing underwriting support if Polymarket seeks to go public.

On the legal front, the source says that more than a dozen US states have filed actions against Polymarket, Kalshi, or both over sports event contracts. It also notes that authorities in several countries have blocked or restricted access to Polymarket, citing gambling-related concerns—an escalation that reinforces why banks, platforms, and corporate partners may be cautious.

This regulatory pressure is relevant to fundraising for a straightforward reason: capital providers tend to price regulatory uncertainty, because outcomes can affect revenue models, user access, and the feasibility of future listings or partnerships. In that sense, Polymarket’s reported push for a high-value round is not occurring in a vacuum—it is happening while multiple jurisdictions test legal boundaries for prediction and event-contract products.

Where things stand next

If 1789 Capital’s reported $300 million commitment and the overall $1 billion round come to pass, Polymarket’s investor base would grow further at a time when the firm’s operating environment is still contested. Market participants should watch for confirmation of the deal terms, any changes to the regulatory strategy being pursued, and whether banking and compliance hurdles ease enough to support sustained growth.
