Donald Trump Jr. Leaves Kalshi, Keeps Polymarket Role a Week After Democrats Win Congress

Donald Trump Jr. has exited his role at prediction market Kalshi, which described the split as mutual and linked it to his venture firm 1789 Capital’s investment in rival Polymarket; he retains his position at Polymarket. The departure comes a week after Democrats won Congress, though neither company tied the move to the election outcome. The overlap had raised conflict-of-interest questions given Kalshi and Polymarket compete directly in event contracts. Trump Jr.’s dual affiliation had been seen as a marketing asset for both platforms as they vie for U.S. market share. Watch for how quickly Kalshi names a replacement and whether Polymarket leans further into the Trump connection as it expands domestically.
