What happened
Kalshi said it has ended its advisory agreement with Donald Trump Jr. The firm traced the move to the discovery that 1789 Capital, his venture firm, held a stake in rival platform Polymarket. Kalshi called the separation mutually agreed.
How the exit unfolded
Conversations about Trump Jr.'s exit began in August after 1789 Capital disclosed the Polymarket stake. Over the following talks, both sides reached the same conclusion: his advisory role conflicted with being a principal investor in Polymarket. Reuters was the first outlet to report his departure.

Why this matters for investors
The timing of the change followed Democrats taking control of the House and the Senate, and the advisory relationship ended after the August disclosure and subsequent discussions. If you follow corporate governance or ownership ties around prediction market platforms, this episode shows a firm publicly tying an advisory departure to an investor stake in a rival. That sequence of disclosure, discussion, and termination is now part of the public record for anyone tracking these platforms or the people behind them.
