Kalshi Ends Donald Trump Jr. Advisory Role Over Polymarket Deal

Prediction market platform Kalshi has ended its advisory relationship with Donald Trump Jr., a decision the company tied to his venture capital firm’s increased investment in rival Polymarket, according to Cryptopotato. A Kalshi spokesperson confirmed the split and said the two sides had begun discussing it in August, after 1789 Capital led Polymarket’s latest funding round.

The timing matters because Trump Jr. had joined Kalshi in January 2025 specifically to help it reach conservative audiences, including supporters of the MAGA movement. His exit now lands as the prediction-market industry faces rising political and regulatory attention.

Dual connections and the timeline

Kalshi’s concern centred on the growing overlap between Trump Jr.’s advisory role and 1789 Capital’s deepening ties to Polymarket. Cryptopotato reported that Kalshi began discussing 1789 Capital’s investment in Polymarket after news of the deal surfaced in August, and that the company reached out to Trump Jr. during the fall to address the situation.

Kalshi’s spokesperson told Reuters that talks about ending the arrangement began in August, shortly after 1789 Capital took the lead on Polymarket’s $1 billion round. The sequence matters: the advisory split was not abrupt, but followed months of internal discussion after the competitor investment became public.

Political scrutiny and what comes next

With Democrats holding both chambers of Congress after the midterms, companies with ties to the Trump administration face closer attention from lawmakers. Cryptopotato reported that some employees worried that having the president’s son on the advisory team could draw unwanted attention; Kalshi pushed back, saying it had neither discussed nor considered the political implications.

Separately, Senator Elizabeth Warren has called for tougher action against insider trading on prediction markets, and both Kalshi and Polymarket have made substantial political donations to candidates from both parties this year, according to campaign finance records cited by Cryptopotato.

Why it matters

For prediction markets, credibility is the product. An advisory arrangement that straddles a competitor’s funding round creates a visible conflict, and Kalshi’s decision removes one source of it before the new Congress settles in. The episode also shows how quickly political relationships that once helped audience reach can become a liability when the political weather shifts.

Regulators are already circling. Our earlier reporting on the CFTC warning Kalshi of possible charges over contract notifications shows the compliance pressure is live, not hypothetical.
