Kalshi ends Trump Jr. advisory deal over Polymarket investment

Kalshi has ended Donald Trump Jr.’s advisory contract after his venture capital firm, 1789 Capital, deepened its investment in rival prediction market Polymarket. Kalshi says both sides agreed to end the role, with discussions beginning in August. 1789 Capital previously committed roughly $300 million to lead a $1 billion Polymarket funding round. Trump Jr. joined Kalshi in January 2025 before taking a seat on Polymarket’s advisory board. Prediction market operators face disputes over state gambling laws and federal oversight of event contracts. Reuters reported on Nov.
