Polymarket reportedly secures $300 million from Trump-linked 1789 Capital

The round would value Polymarket at $21 billion, amid ongoing regulatory scrutiny from states and federal authorities.

Funding round

Polymarket, a blockchain-based prediction market, is reportedly raising approximately $1 billion in a new funding round, with about $300 million coming from 1789 Capital, an investment firm in which Donald Trump Jr. is a partner. The Wall Street Journal, citing people familiar with the matter, reported the investment on Monday, which would value Polymarket at $21 billion. This new investment would bring 1789 Capital's total stake in the platform to roughly $500 million, making it one of the largest backers.

The funding follows a prior $200 million investment by 1789 Capital in Polymarket. The firm has also backed other tech-related projects, including the Enhanced Games, an event sometimes described as the "steroid Olympics" due to its allowance of performance-enhancing drugs.

Previous investments and valuation

Polymarket reportedly began discussions in April to raise $400 million at a potential $15 billion valuation, a figure below the $22 billion valuation of its main competitor, Kalshi. The current round's valuation of $21 billion suggests a significant upward revision.

ICE, the parent company of the New York Stock Exchange, remains Polymarket's largest disclosed investor. In a July 30 filing, ICE reported a combined $1.6 billion investment in Polymarket preferred shares. Those holdings had a carrying value of approximately $2 billion as of June 30, representing about 22% of outstanding shares, or 14% on a fully diluted basis.

Regulatory landscape

Prediction markets are facing increased scrutiny from regulators in the US and abroad. At least 20 states are involved in litigation against prediction sites over sports wagers, and more than a dozen states have taken legal action against Polymarket, Kalshi, or both over sports event contracts. Authorities in several countries have also blocked or restricted access to Polymarket.

The federal government, particularly under the current administration, has argued that the Commodity Futures Trading Commission (CFTC) should be the sole regulator of prediction markets, not state governments. The CFTC has sued at least nine states over their attempts to regulate the industry.

A coalition of 44 state attorneys general recently signed a letter arguing that the CFTC does not have the authority to regulate sports-related wagers on prediction sites.

The New York Times reported that Trump Jr. attended an event with conservative state attorneys general, where he claimed the prediction industry already has "robust oversight" and described prediction sites as a tool "overseen by federal officials, not state attorneys general."

Banking relationship

In a separate development, JPMorgan Chase reportedly ended a banking relationship with Polymarket on August 14 over regulatory concerns. However, the bank indicated it remains interested in a potential underwriting role should Polymarket decide to go public.

Polymarket and 1789 Capital have been approached for comment, and TechCrunch has also reached out to Polymarket for a response.

What was claimed, and who backed it

AI-extracted; can misattribute a claim — see Methodology.

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status is Contested when two claims on this page negate each other; otherwise it counts the distinct outlets we found asserting that specific claim — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
