Kalshi Ends Advisory Deal With Donald Trump Jr. Over Polymarket Conflict of Interest

Kalshi has terminated Donald Trump Jr.’s advisory contract after his ties to rival prediction market Polymarket created a conflict of interest. The split comes as both platforms face mounting legal challenges from state authorities that argue they function as unlicensed sportsbooks. Trump Jr. had served as an advisor to Kalshi while also holding a stake in Polymarket, a dual role that became untenable as competition between the two venues intensified. The move highlights growing friction in the prediction market sector, where Kalshi and Polymarket are vying for dominance amid regulatory scrutiny. What to watch next is whether the separation signals a broader realignment of political and financial backers across the two platforms, and how the pending state lawsuits shape their respective growth trajectories.
