Kalshi Ends Advisory Deal With Donald Trump Jr. After Investment in Competitor

Kalshi and Donald Trump Jr. end advisory partnership

The prediction market platform Kalshi has ended its professional relationship with Donald Trump Jr. A prediction market is a platform where users can trade or bet on the outcome of future events, such as elections or economic data.

The decision follows a significant investment by Trump Jr.’s venture capital firm, 1789 Capital, into a competing platform called Polymarket. Kalshi stated that the move to end the advisory role was mutual and based on this business conflict.

Key details of the agreement

• Donald Trump Jr. joined Kalshi as a strategic adviser in January 2025.
• He originally received an equity stake in the company valued at approximately $300,000.
• His firm, 1789 Capital, led a $1 billion funding round for the rival platform Polymarket.
• The venture capital firm is expected to contribute about $300 million to that round, valuing Polymarket at $21 billion.

Company cites competition as the primary reason

A spokesperson for Kalshi told Reuters that discussions about ending the advisory role began in August. This timing aligns with when 1789 Capital took a leading role in the funding for Polymarket. The company explicitly stated that the decision was due to the investment in a competitor and denied that political reasons were involved.

Reported internal concerns over political shifts

While the company denied political motives, other reports suggest different internal discussions. Two individuals familiar with the situation told Reuters that some people within Kalshi expressed concerns regarding recent political changes. Specifically, they noted the potential impact of the Democratic party's success in midterm elections on the company's future.

Confirmed facts regarding the split

It is confirmed that Donald Trump Jr. is no longer an adviser for Kalshi. Both parties agree that the separation was mutual. It is also confirmed that his firm is now a major investor in Polymarket, which competes directly with Kalshi in the prediction market industry.

Uncertainty regarding internal motivations

It remains unclear if the political climate played a significant role in the decision-making process. While Kalshi's official stance is that the move was strictly business-related due to a conflict of interest, the reported concerns from internal sources suggest there may have been additional worries about how the advisory role would be perceived following election results.
