Donald Trump Jr has stepped down from his position as a paid strategic adviser for the prediction market platform Kalshi. According to a statement released by the company on Thursday, the parting was a mutual business decision triggered by a conflict of interest involving Trump Jr’s own investment firm, 1789 Capital. The split follows reports that his firm recently ramped up its financial stake in Polymarket, which stands as Kalshi’s primary rival in the rapidly growing event betting space.
The departure arrives at a politically sensitive moment, coming just one week after Democrats secured control of both the House and Senate in the midterm elections. Congressional leaders have already signaled their intent to launch investigations into various Trump family investments, specifically scrutinizing their overlapping business ties within the prediction market industry. A spokesperson for Kalshi noted that while they were grateful for help in expanding their customer base, the significant investment in a direct competitor made continuing the advisory relationship untenable.
Trump Jr originally joined Kalshi shortly after his father began his second presidential term in January 2025, though he had already established himself as an investor in Polymarket months prior. This duality created a complex dynamic during a period when both platforms experienced explosive growth and benefited from a friendly regulatory environment fostered by the White House. Specifically, the Commodity Futures Trading Commission moved to expand product offerings across the sector, even permitting trades on sports related contracts.
Despite these cozy relations with the executive branch, both firms have firmly denied that any financial connections to the First Family influenced government regulation of their industry. While those claims remain contested by political opponents, 1789 Capital confirmed it increased its holding in Polymarket during a recent fundraising round this past August, effectively sealing the deal for Trump Jr’s exit from Kalshi.
