18 Months Of Discussions Behind “Tens Of Millions Of Dollars” In Investment
For the uninitiated, Polymarket is a blockchain-based prediction platform where users bet on real-world outcomes. The topics of these wagers can range from elections and court rulings to geopolitical flashpoints.
So far, the platform has processed over $8 billion in bets, including $2.5 billion during the 2024 US election cycle, making it the world’s most active prediction market by trading volume.
Trump Jr. heaped praises on Polymarket’s ability to “cut through media spin and so-called ‘expert’ opinion by letting people bet on what they actually believe will happen.”
Simultaneously, Polymarket’s CEO Shayne Coplan hailed this partnership as “a significant milestone” for the company.
Trump Jr.’s Polymarket advisory board appointment comes as the platform experiences a major growth spurt, attracting $6 billion in wagers in the first half of 2025 alone.
Coplan stated, “We are proud to formally welcome 1789 Capital as a strategic partner and Donald Trump Jr. to our advisory board as we continue building our platform to reflect real-world sentiment, in real time, for all to see.”

Polymarket Eyes US Comeback With $1B Valuation After Regulatory Clearance
A lot of eyeballs are currently on the prediction platform, thanks to its rapid growth and recent regulatory breakthroughs.
It is close to finalising a $200 million funding round led by the Peter Thiel-backed Founders Fund, squarely putting Polymarket within the $1 billion valuation range, thereby granting it Unicorn status.
Polymarket has acquired QCEX, a CFTC-regulated exchange and clearinghouse, for $112 million.
This paves the way for us to welcome American traders again.

Additionally, the company recently acquired QCEX, a U.S.-licensed derivatives exchange for $112 million, which could potentially result in Polymarket’s US return after years of absence.
The platform has blocked all US users since 2022 following a regulatory settlement over unauthorised access. However, the US Department of Justice (DOJ) and the Commodity Futures Trading Commission (CFTC) officially closed their investigations into this matter on 15 July 2025, clearing the way for its re-entry in the US market.

Further to this, in June, Polymarket partnered with Elon Musk’s X platform, becoming its official prediction market partner. The integration of Polymarket with X includes forecasts along with AI-powered insights from Musk’s chatbot, Grok.
1789 Capital’s founder, Omeed Malik, stated, “Polymarket stands at the intersection of free expression and financial innovation by empowering individuals with real-time truth in a world clouded by noise, and we are proud to support its vision.”
Users generally view prediction markets such as Polymarket to be more accurate than traditional polling since they are faster than surveys in capturing public sentiments.
This is reinforced by its trading activity surpassing sports betting giants such as FanDuel and DraftKings.

Trump Bros Go Full Crypto
Trump Jr. has been steadily expanding his presence in the crypto sphere. In July this year, he invested $4 million in Thumzup Media Corp., a Los Angeles startup that pays users to promote brands on Instagram.
While the company holds Bitcoins in its balance sheet, it has been posting heavy losses. Still, its board recently approved plans to hold up to $250 million in crypto, including assets like Ether, Solana, Dogecoin, XRP and USDC.
Meanwhile, Eric Trump’s venture, American Bitcoin, majority-owned by mining firm Hut 8, raised $220 million to fund large-scale Bitcoin mining and reserves. According to SEC filings, a part of the raise was conducted in Bitcoin instead of cash.
American Bitcoin is preparing for a Nasdaq listing under the ticker ABTC, through a merger with Gryphon Digital Mining. Once listed, the merger will grant the Trump brothers and existing shareholders 98% control.
Additionally, reports surfaced on 16 August 2025, that the Trump brothers are looking to build a corporate Bitcoin holding on the scale of Michael Saylor’s Strategy via acquisitions in Asia.
