Trump Jr.-Linked 1789 Capital Expands Stake During Latest Polymarket Raise
1789 Capital, the venture firm linked to Donald Trump Jr., has led a new $1Bn funding round for the ongoing Polymarket raise, valuing the prediction-market platform at $21Bn. Alexa Henning, a spokesperson for 1789 Capital, said the firm will invest about $300M in the round.
The Trump Jr-linked venture firm had previously invested roughly $200M in Polymarket, the report said. The new investment adds to the firm’s existing exposure to the platform.
Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange, which previously invested heavily in Polymarket’s earlier funding rounds, has indicated it is considering participating in or providing support for the current round.
Aside from ICE and 1789 Capital, earlier investor backing in recent months included hedge fund D.E. Shaw & Co. and venture capital firm G Squared, all huge names in the VC industry, signaling that a potential Polymarket IPO would likely see huge demand.
Polymarket Raise: Prediction Market Valuation Has Risen From $15Bn to $21Bn in a Few Months
Polymarket was valued at around $15Bn only a few months earlier, according to the report. The new $21Bn valuation represents a 40% increase, as reported by The Wall Street Journal.
Kalshi, Polymarket’s main rival, allows users to bet on outcomes across a range of events, including presidential remarks and reality-TV results. Both platforms have grown significantly in popularity over the past year, according to the Traders Union report.
Per data from PolymarketAnalytics.com, there are over 209,000 markets available, and the platform has processed more than $67M in volume over the past 24-hours, with a reported $46Bn in volume since it launched three years ago.
Trump Family Involvement in Prediction Markets
The latest Polymarket raise comes as the Trump family’s presence in the crypto industry continues to expand. In 2025, Trump Jr. became an adviser to Kalshi and received shares in the company worth more than $300,000, according to the report. He also serves as an adviser to Polymarket.
President Donald Trump’s administration has taken an increasingly favorable stance toward prediction markets, the report said. Michael Selig, identified as Trump’s appointee to head the US Commodity Futures Trading Commission, has publicly supported such platforms, while the agency has challenged efforts by individual states to regulate them independently.
Investor Caution Around Trump-Linked Projects
TRUMP CRYPTO BUYERS ARE $4.7B UNDERWATER!
A new Public Citizen report estimates investors in Trump-linked crypto products are down at least $4.7 billion.
Most of that is paper losses, not cash already sold.

The Trump family’s involvement in crypto remains controversial. Advocacy group Public Citizen estimated that investors in projects linked to Donald Trump have lost at least $4.7Bn, with most of those losses unrealized, according to the report.
About $3.2Bn of the estimated losses is tied to the TRUMP memecoin, while at least another $1Bn is linked to World Liberty Financial’s WLFI token. Public Citizen also attributed investor losses to Trump Media’s Bitcoin treasury and Trump’s digital trading card collections.
The group said Trump earned at least $1.4Bn from crypto-related ventures in 2025, including income connected to tokens allocated to a company linked to the president and licensing fees.
