Donald Trump Jr. Exits Kalshi Advisory Role, Remains Polymarket Advisor

The overlap between political capital and prediction-market positioning is becoming harder to separate, and this exit is the clearest signal yet that affiliations are consolidating rather than diversifying. Trump Jr.'s continued Polymarket advisory role, following his firm's investment there, makes the split with Kalshi read less as a routine departure than as a choice of camp. For the prediction-market sector, the real question is whether prominent political figures tied to one platform become a competitive advantage or a regulatory liability for that venue.
