Prediction market Kalshi terminates contract with Donald Trump Jr. advisor

Kalshi has ended its advisory contract with Donald Trump Jr., the president's eldest son, confirming the move to Reuters without giving a reason. The termination came two days after Senators Elizabeth Warren and Jeff Merkley questioned the White House about his financial ties to prediction markets. Trump Jr. had received roughly $300,000 in Kalshi equity when the platform was valued at under $2 billion; Kalshi later raised funding at a $22 billion valuation. He remains an advisor to rival Polymarket, a relationship that could draw further scrutiny as the two platforms compete. Watch for any disclosure of the reason for the split and whether lawmakers extend their inquiry to his Polymarket role.
