Donald Trump Jr. leaves paid advisory role at prediction market Kalshi

Donald Trump Jr. departed from his paid advisory role at prediction market Kalshi on Thursday after the two parties reached what was framed as a mutual agreement following the president’s son growing closer to competitor Polymarket.

Trump first joined Kalshi following his father’s inauguration in 2025 as a “strategic advisor,” and later that year, he also joined the advisory board at Polymarket. In August, Trump’s investment firm, 1789 Capital, announced it would be increasing its investment in Polymarket by a reported tens of millions of dollars. Kalshi said Thursday Trump’s relationship with its competitor led to his departure.
