Donald Trump Jr. Departs Advisory Role at Prediction Market Kalshi

Prediction market Kalshi has ended its advisory contract with Donald Trump Jr. following reports of a conflict of interest involving an investment in a rival platform.

TLDR: Donald Trump Jr’s advisory contract with Kalshi ended after 1789 Capital’s investment in Polymarket, which the exchange identified as the reason for the mutual split. The prediction market operator said the decision was mutual and followed 1789 Capital’s investment in rival Polymarket, denying political considerations. Trump Jr. joined Kalshi as a strategic adviser in January 2025, helping the prediction market expand its customer base and strengthen its market presence.

The president's son will no longer serve as an advisor at Kalshi. Kalshi's decision underscores the importance of managing conflicts of interest, especially when seeking new capital and maintaining competitive integrity.
