1789 Capital Leads $1B Polymarket Round

1789 Capital, the venture capital firm where Donald Trump Jr. is a partner, is leading a new funding round for the prediction market platform Polymarket, according to a spokesperson for the firm. The round is set to raise $1 billion and values Polymarket at $21 billion, as reported by The Philadelphia Inquirer, citing spokesperson Alexa Henning.

The spokesperson said 1789 Capital will invest around $300 million in the round. The firm previously invested about $200 million in Polymarket, which is currently valued at about $15 billion, according to the same spokesperson. If the new investment proceeds, 1789 Capital's total disclosed exposure to Polymarket would reach roughly $500 million, positioning it among the platform's most prominent investors, as reported by the Wall Street Journal and cited in coverage by Crypto Breaking News and The Philadelphia Inquirer.

The Wall Street Journal reported that 1789 Capital would participate in the $1 billion round, with the additional $300 million commitment. Bloomberg earlier reported that 1789 Capital was leading the round, according to The Philadelphia Inquirer.

Political and Financial Context

Polymarket and rival Kalshi have seen a surge in popularity over the past year, The Philadelphia Inquirer noted. The platforms allow users to wager on the outcomes of events ranging from presidential speeches to reality TV weddings, such as who will get married on "Love Is Blind."

The Trump family has built a financial stake in the prediction market industry. Donald Trump Jr. joined Kalshi as an adviser last year and received shares worth more than $300,000, according to The Philadelphia Inquirer. He also began advising Polymarket and invested through 1789 Capital. President Donald Trump has taken steps to boost the industry, including appointing Michael S. Selig to lead the Commodity Futures Trading Commission, which oversees prediction markets. Selig has spoken enthusiastically about the companies and sued states that tried to regulate them, The Philadelphia Inquirer reported. The president declared on Truth Social that prediction markets would "thrive" under his leadership and called Selig "respected by all."

1789 Capital has invested in companies with large government contracts and others that benefit from Trump policies, The New York Times has reported, according to The Philadelphia Inquirer. The firm has also bought shares in private companies like SpaceX, Anduril, Cerebras, and Reflection AI before they went public. Two years ago, 1789 Capital managed a few hundred million dollars; it now oversees more than $3 billion, The Philadelphia Inquirer reported. Donald Trump Jr. told the Times he invests as a private citizen with no policy role.

Regulatory Scrutiny and Investor Landscape

The new funding round comes amid regulatory pressure on prediction markets in the US and internationally, as noted in Crypto Breaking News coverage. More than a dozen US states have filed actions against Polymarket, according to the same source. JPMorgan Chase ended a banking relationship with Polymarket over regulatory concerns but may offer underwriting support if Polymarket goes public, Crypto Breaking News reported.

Polymarket had earlier begun discussions to raise $400 million around April at a potential valuation of $15 billion, which was reportedly below the $22 billion valuation of Kalshi, according to Crypto Breaking News. ICE remains the largest disclosed investor in Polymarket, with an approximate $2 billion carrying value of its holdings as of June 30, as stated in an ICE 10-Q filing cited by Crypto Breaking News. The filing indicated preferred shares representing about 22% of outstanding shares, or about 14% on a fully diluted basis.

Cointelegraph, as reported in its own coverage, reached out to both 1789 Capital and Polymarket for comment.

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.
