Kalshi has ended Donald Trump Jr.'s advisory contract following 1789 Capital's investment in rival Polymarket, according to an exclusive report by Reuters.
The decision followed 1789 Capital leading Polymarket's latest funding round, creating competing interests between the prediction markets.
“We have mutually agreed to end Don's advisory role after his firm's significant investment in a competitor this past summer,” a Kalshi spokesperson said in a statement.
Discussions over ending the advisory relationship began in August, with both sides agreeing to terminate the arrangement.
“We are grateful for his contributions in helping us market Kalshi to more customers,” a Kalshi spokesperson said.
Trump Jr joined Kalshi as a strategic adviser in January 2025, receiving an equity stake reportedly worth $300,000.
His departure comes as US lawmakers increase scrutiny of prediction markets over insider trading, politically sensitive wagers and potential conflicts of interest.
The decision highlights growing governance challenges as Kalshi and Polymarket compete for customers, investment and regulatory acceptance.
