Donald Trump Jr. has turned the conflict between America's two largest event betting platforms into a risk-free financial strategy. His venture fund, 1789 Capital, invested $300 million in Polymarket, while he also holds a stake in its direct competitor, Kalshi. This arrangement guarantees him profit regardless of who wins this race.
The $300 million investment was made as part of a Polymarket funding round that valued the platform at $21 billion. In parallel, the stake in Kalshi was acquired back in 2025, when the company was valued at a modest $300,000. Today, Kalshi's market capitalization has soared to $22 billion, making this one of the most successful investments in 1789 Capital's portfolio.
A dual role: advisor to two competing camps
In January 2025, Trump Jr. officially took a paid position as a strategic advisor at Kalshi. Just seven months later, he joined the advisory board of Polymarket, coinciding with 1789 Capital's first major investment in the platform. Thus, the U.S. president's son found himself on both sides of the barricades simultaneously, linking both companies not only through financial flows but also through his consulting obligations.
Such a configuration inevitably raises questions about ethics and conflicts of interest. At Kalshi, however, they were quick to assure that Trump Jr. is exclusively involved in marketing strategies and does not participate in regulatory matters. But it is obvious that his influence extends far beyond formal duties.
Direct access to regulators and political lobbying
Of particular interest is the fact that Trump Jr. personally lobbied for the industry's interests before Republican attorneys general. At a closed meeting in New Orleans in March, he urged them to stop pressuring betting platforms, arguing that the campaign against them was launched by traditional gambling companies to protect their own businesses.
The situation is reaching a boiling point: the CFTC has filed lawsuits against nine states, attempting to block their efforts to regulate betting markets at the local level. Eight of these states are led by Democratic attorneys general. The confrontation has been most acute in Arizona, where a criminal case over illegal gambling services was opened against Kalshi in March.
It is telling that the U.S. president himself has supported the industry: in May, he called betting markets a new financial product and spoke in favor of keeping CFTC oversight over them. Thus, the Trump family's interests have become woven into the very fabric of the regulatory dispute shaping the future of this sector.
My analysis: This ownership structure is a rare case where political capital and financial markets are intertwined so tightly. Trump Jr. has created a perfect hedge: any regulatory decision, any outcome of legal battles, and even one platform's victory over the other will bring him profit. This is not just an investment — it is strategic control over an entire sector, and markets should closely watch how this dynamic will affect the valuation of both companies in the future.
