Prediction markets are perhaps the most striking phenomenon of the current crypto and financial cycle. But while traders argue over the probability of one event or another, Donald Trump Jr. has found a way to beat the system itself. His venture fund, 1789 Capital, invested $300 million in a Polymarket round, valuing the platform at $21 billion. At the same time, he is also a paid strategic advisor and shareholder of a direct competitor—Kalshi, whose valuation has soared to $22 billion.
In essence, we are witnessing a unique situation: a key figure of the American political elite is now financially motivated in the success of both opposing sides. This is not just portfolio diversification, but a strategic gambit that makes him immune to the outcome of the battle for market share.
Double Bottom: Advisor to Two Competing Camps
It all began in January 2025, when Trump Jr. took a paid position as a strategy advisor at Kalshi. Just seven months later, in August, he joined the advisory board of Polymarket, and his fund became one of the anchor investors. Thus, he simultaneously advises two platforms that are fiercely competing for the same users and for the right to set the rules of the game in the political betting market.
The obvious conflict of interest has not gone unnoticed. In response to media inquiries, Kalshi representatives hastened to assure that Trump Jr. is exclusively involved in marketing strategy and does not touch on regulatory issues. However, this statement looks extremely naive, given his direct lobbying of the industry's interests before regulators.
Shadow Lobbying and Legal Battles
According to the information available to me, Trump Jr. personally persuaded Republican attorneys general to stop pressuring betting platforms. He claimed that the campaign against them was initiated by traditional gambling companies to protect their business. This happened against the backdrop of the CFTC filing lawsuits against nine states, trying to block their attempts to regulate prediction markets at the local level.
The situation became especially acute in Arizona, where a criminal case was opened against Kalshi for illegal gambling services. It is telling that eight of the nine states trying to stifle the industry are led by Democrats. This turns the fight over prediction markets into part of a larger political game, where at stake are not only billion-dollar valuations but also control over a new class of financial instruments.
President Trump himself in May called betting markets a new financial product and spoke in favor of maintaining CFTC control over them. Thus, the Trump family's interests are now inextricably linked to the fate of both platforms: any defeat of one of them in court or in a regulatory battle will hit the family business as a whole.
My conclusion: This situation is a vivid example of how political capital is converted into financial capital. Trump Jr. has built a perfect hedging position, but for the market, this is an alarming signal. The concentration of such great influence in the hands of one family, albeit indirectly, undermines the very principle of decentralization on which such platforms should be built. Regulators should carefully examine not only the legal purity of the deals but also the ethical side of such a symbiosis of power and capital.
