Cut ties quickly? Kalshi ends partnership with Trump Jr.'s adviser, citing his venture capital firm's increased stake in Polymarket.

BlockBeats news, November 13, according to Reuters, prediction market platform Kalshi has terminated its consulting contract with Donald Trump Jr., the eldest son of U.S. President Donald Trump.

A Kalshi spokesperson stated that both parties mutually agreed to end the cooperation due to Donald Trump Jr.'s venture capital firm 1789 Capital making a significant investment in competitor Polymarket this summer. Related communications began in August when 1789 Capital led Polymarket's most recent funding round.

Kalshi appointed Donald Trump Jr. as a strategic advisor in January 2025, with equity as compensation.
