Key Points
- 1789 Capital’s combined Polymarket stake reaches $500 million as the platform’s valuation jumps 40% in four months, from $15 billion to $21 billion.
- Polymarket generates roughly $1.1 billion in annualised revenue against Kalshi’s $4 billion, yet both companies sit at almost identical valuations.
- Congressional Democrats are investigating 1789 Capital, while more than ten states are suing Polymarket in court, a fight some observers believe could reach the Supreme Court.
Prediction markets have gone from a niche corner of the crypto world to a place where the NYSE’s parent company, a Trump-linked venture fund, and some of Wall Street’s biggest names are writing billion-dollar cheques. Polymarket is at the centre of all of it, and its latest raise is the most revealing chapter yet.
Polymarket is seeking to raise $1 billion in a fresh round of funding that will value the blockchain prediction marketplace at $21 billion after the money. This comes as an increase of 40% since the platform was valued at $15 billion following an investment round four months ago in April, where D.E. Shaw and venture capital firm G Squared were among the new investors. The lead investor in the current round is 1789 Capital, a venture capital firm jointly founded by Donald Trump Jr., who is making a fresh investment of around $300 million into the platform. The new investment is in addition to about $200 million that 1789 has already invested in Polymarket.
What is often overlooked with the headline number is how fast that number has been compiled. The value of Polymarket had just been $300 million in recent times. But by October 2025, Intercontinental Exchange – which runs the New York Stock Exchange – joined in a funding round where the value of the platform stood at around $9 billion. ICE later invested an additional $600 million in the company in March 2026, making its total investment stand at $1.6 billion. It continues to be the biggest single investor with 22% of the company’s stock. In a July regulatory filing, it was shown that ICE recorded a $389 million fair-value gain on its Polymarket investment during the first quarter of 2026 from its share price rise alone.
1789 Capital’s Half-Billion Commitment, and the Dual Adviser Problem
1789 Capital’s journey into Polymarket began before the 2024 US presidential election, when Polymarket CEO Shayne Coplan sat alongside Trump Jr. and 1789 Capital founder Omeed Malik at the Republican National Convention. After Trump’s victory, Trump Jr. formally joined 1789 Capital as a partner, and the fund invested in Polymarket shortly after. 1789 Capital spokeswoman Alexa Henning confirmed the fund’s $300 million contribution to the new round, one of the few named on-record confirmations to emerge from the deal.
Growth in the fund has been impressive during the last year. It has gone from assets of $200 million to an estimated $3.5 billion, while its main fund has made a return of roughly 200% by June 2026. Such rapid growth does not go unnoticed, especially because it has. Democratic representative of Maryland Jamie Raskin has written to the leadership of 1789 Capital demanding a list of investments, communications with the government and the reason for bringing Trump Jr. into the fold.
One detail that most coverage has glossed over: Trump Jr. advises both Polymarket and its rival Kalshi simultaneously. According to the Financial Times, Trump Jr. received equity in Kalshi valued at more than $300,000 when he joined that platform as a strategic adviser in January 2025. His fund is now writing a $300 million cheque to Kalshi’s direct competitor. That is not illegal. But it is the kind of overlap that tends to matter when regulatory or antitrust scrutiny eventually arrives, and in this industry, it will.
The Revenue Gap Investors Are Choosing Not to Talk About
Here is the number that does not appear prominently in most reports on this raise. Kalshi generates approximately $4 billion in annualised revenue, driven largely by sports contracts, and claims 95% of the US prediction market by revenue. Polymarket’s annualised revenue for the same period sits at around $1.1 billion. The two platforms are being valued at $21 billion and $22 billion respectively.
Kalshi closed a $1 billion Series F in May 2026 at a $22 billion valuation, backed by Coatue, Sequoia Capital, Andreessen Horowitz, Morgan Stanley, and ARK Invest. Sequoia and Wellington Management are now in advanced discussions to lead a further $750 million raise for Kalshi at a $40 billion valuation, with an IPO reportedly possible in 2027.
Polymarket’s US exchange, which opened broadly in May 2026 after a waitlist period since December 2025, has seen daily notional volume on the domestic platform climb to over $100 million, with the international side handling more than $150 million per day. Those are real operating numbers. But the gap with Kalshi on revenue is wide, and at nearly identical valuations, someone is making a very different judgement about Polymarket’s trajectory than the current figures would suggest.
The Regulatory Rebuild That Made This Round Possible
Polymarket’s US comeback did not happen quickly or cleanly. The company exited the American market in 2022 after the CFTC fined it $1.4 million for operating an unregistered futures exchange and required it to block American users. FBI agents raided CEO Shayne Coplan’s New York apartment in November 2024 during an investigation into whether Polymarket had continued to allow US users to trade. No charges were filed; the DOJ and CFTC closed their probes in July 2025.
The return was built on a $112 million acquisition. In July 2025, Polymarket bought QCEX, a CFTC-licensed derivatives exchange and clearinghouse, giving it the regulatory framework to serve US users again. Coplan described it at the time: “Demand is greater than ever, not just in user growth and trading volume, but in how mainstream audiences are turning to Polymarket to separate signal from noise, bias, and speculation.” In the first half of 2025 alone, users made around $6 billion in predictions on the platform. Since the US relaunch, annualised revenue has risen to more than $1.2 billion.
The credibility rebuild has extended into the platform’s operations. Polymarket has appointed former FBI investigator Shana Bautista as global head of investigations and intelligence, deployed machine learning and blockchain analytics to flag suspicious activity, struck a partnership with Palantir, and brought in Travis VanderZanden, formerly of Uber and Lyft, as chief growth officer. Hayk Mkrtchyan, who previously built infrastructure for the New York Stock Exchange, has been hired to oversee the US exchange’s development.
The State vs. Federal Fight That Has Not Been Resolved
Even with a CFTC-licensed entity in hand, Polymarket is not operating on settled legal ground. More than ten states are currently litigating against Polymarket and other prediction market platforms, with state attorneys general arguing that oversight authority rests with individual states rather than federal regulators. A recent federal appeals court ruling favoured that position, and some observers now believe the dispute is heading toward the Supreme Court. Polymarket is also separately facing a CFTC probe tied to its social media conduct, following reports of deceptive promotional activity. The company has said it initiated an internal review of its promotional content.
The Trump administration has pushed back against state-level regulation consistently. In March 2026, Trump Jr. delivered a keynote at a Republican Attorneys General Association conference, making the case for federal rather than state regulatory authority over prediction markets. He did so while 1789 Capital held a substantial and growing stake in Polymarket. That speech has received almost no coverage alongside this funding announcement, and it should.
Expert Analysis: You Are Not Paying $21 Billion for the Revenue – So What Are You Paying For?
The surface reading of this round is simple: prediction markets are a hot sector, and Polymarket is one of the two dominant platforms. But we think the more honest reading is less comfortable.
A platform generating $1.1 billion in annualised revenue, against a rival pulling in $4 billion, is being valued at nearly the same figure. The fund leading that valuation has its general partner simultaneously advising the rival, lobbying state regulators on the platform’s behalf, and sitting in an administration that controls the federal regulator overseeing the entire space. We are not suggesting anything improper has occurred; what we are saying is that the structure of this investment is unlike any other in the sector, and investors deserve to understand what they are actually buying.
Prediction markets are no longer a crypto curiosity. ICE, Sequoia, Andreessen Horowitz, and now Palantir are all in. But Polymarket’s $21 billion price tag is not primarily a bet on current earnings. It is a bet that political adjacency, regulatory goodwill under a friendly administration, and a CFTC-licensed US exchange can be converted into dominant revenue before the legal environment shifts. That thesis might be right. It might not. Either way, the investors writing the cheques already know that the biggest risk to this platform is not competition. It is the day the political winds change direction.
