Donald Trump Jr. is no longer a paid adviser for Kalshi, the prediction market company said Thursday, according to the Guardian, ABC News and CNBC. Kalshi described the exit as a mutual business decision.

Why it matters

Trump Jr. had been tied to both Kalshi and its competitor Polymarket, which the Guardian and ABC News describe as Kalshi's biggest competitor. The Guardian and ABC News report that Democrats have said they plan to investigate the Trump family's business relationships with both prediction markets.

What Kalshi says

Kalshi spokesperson Dani Lever said the company had "mutually agreed to end Don's advisory role after his firm's significant investment in a competitor this past summer." She added that Kalshi was grateful for his contributions in helping market the platform to more customers.

CNBC, citing the spokesperson, reported that conversations about his exit began in August, after his firm, 1789 Capital, announced a major stake in Polymarket. Both sides agreed it was a conflict of interest to keep him as an adviser while he was a top investor in Polymarket, the spokesperson said. CNBC reported that Reuters was first to report the departure.

Background and open questions

The Guardian and ABC News report that Trump Jr. became a paid "strategic adviser" for Kalshi shortly after President Trump's second-term swearing-in in January 2025, and has been a Polymarket investor since August 2025. They describe Polymarket as Kalshi's biggest competitor.

The Guardian and ABC News report that the announcement came a week after Democrats won control of both the House and Senate in the midterm elections; CNBC says Democrats secured a majority in both chambers. The Guardian and ABC News also report that Democrats have said they plan to investigate the Trump family's investments, including business relationships with both prediction markets.
