Trump Jr.’s 1789 Capital Leads Massive $1B Funding for Polymarket

The prediction market landscape is undergoing a massive financial transformation, deeply intertwined with political power structures. 1789 Capital, the investment firm led by Donald Trump Jr., is at the forefront of a new funding round for Polymarket. A total of $1 billion is flowing into the platform, catapulting its market value to an impressive $21 billion. This jump demonstrates the strong investor confidence in technology companies that allow users to trade contracts based on the outcomes of elections, economic indicators, and entertainment events.

Donald Trump Jr. has significantly expanded his presence in this sector over recent months. Following his father's return to the White House, he not only took on a partner role at 1789 Capital but also serves as an advisor for Polymarket. Interestingly, he is not exclusively tied to one company, as he also accepted an advisory position at Kalshi in 2025, which earned him equity worth more than $300,000. These connections between politics and private betting markets are sparking heated debates in the U.S. regarding regulation and influence.

Numbers and facts

In detail, the financing round sees 1789 Capital contributing approximately $300 million. The firm had previously invested around $200 million in Polymarket, bringing its total commitment to half a billion dollars. Polymarket was valued at $15 billion earlier this year, highlighting the rapid increase in interest. The business model is based on users trading contracts on the results of political, economic, and other events. Meanwhile, institutional traders are increasingly entering the platform.

However, the legal situation remains complex. While the Trump administration favors oversight by the Commodity Futures Trading Commission (CFTC), many states are resisting. More than a dozen U.S. states have already filed lawsuits against prediction market operators. They argue that these products constitute a form of gambling that should fall under respective state laws. Michael Selig, President Trump's pick to lead the CFTC, supports the industry's expansion and opposes state-level restrictions.

Background

The conflict centers on the question of definition: Are prediction markets financial instruments or bets? Donald Trump Jr. has actively entered this debate. According to reports, he recently discussed the regulatory environment with Republican attorneys general to persuade them to leave regulation to federal authorities. 1789 Capital, meanwhile, denies any conflicts of interest. Nevertheless, the political component remains evident, as Donald Trump himself has publicly voiced support, predicting the sector will grow under his administration.

„Donald Trump Jr.’s participation in the debate has also faced scrutiny. He recently discussed the regulatory environment with Republican state attorneys general and urged them to leave the regulation of prediction markets to federal authorities.“ - 1789 Capital spokesperson

Why it matters for German players

For players in Germany, the situation is entirely different. Polymarket operates in a regulatory gray area or under U.S. financial laws, which offers no legal certainty for German consumers. In Germany, gambling is strictly regulated by the State Treaty on Gambling 2021 (GlüStV 2021). Anyone wishing to play safely in Germany must stick to the whitelist of the Joint Gambling Authority of the States (GGL). Only providers listed there adhere to strict player protection measures.

These include the monthly deposit limit of 1,000 euros, monitored via the LUGAS system, and the 1 euro per spin limit for virtual slots. Prediction markets like Polymarket, which often operate on a crypto basis, offer no connection to the German OASIS blocking system and do not meet GGL requirements. German players using such platforms risk not only losing their money without legal recourse but are technically participating in illegal gambling if the provider lacks a German permit.

What it means for GGL-licensed casinos

For casinos licensed in Germany, the hype surrounding U.S. prediction markets primarily means one thing: competition from unregulated black market offerings. While GGL-licensed operators must pay high taxes and implement strict limits, international platforms lure users with unlimited stakes. The GGL is taking increased action against such offers, but political backing for platforms like Polymarket in the U.S. could further increase their global reach. In Germany, the message remains clear: only providers with a license from Saxony-Anhalt guarantee fair gaming conditions and protection against addiction. Using MGA or Curacao platforms is considered risky compared to GGL casinos due to the lack of German supervision.
