Donald Trump Jr. leaves Kalshi advisory role but keeps Polymarket post

Kalshi◼ and Donald Trump Jr. have mutually ended his advisory role, after his firm 1789 Capital◼ invested in rival Polymarket◼ this summer. Trump Jr. still advises Polymarket, which he joined in August 2025. The move came a week after Democrats won both chambers of Congress, and Senator Elizabeth Warren, expected to take control of the Senate Banking Committee in January, has listed Trump family crypto businesses and prediction markets among early oversight targets.
