## Key points

- Trump Jr. has left Kalshi’s advisory role.
- His firm invested $300 million in Polymarket.
- He may still hold equity in Kalshi.

## Summary

Donald Trump Jr. has ended his advisory role at prediction market Kalshi after his venture capital firm, 1789 Capital, made a substantial investment in rival Polymarket. The move highlights potential conflicts of interest in a sector where Kalshi has received legal and regulatory support from the Trump administration.

Kalshi said it and Trump Jr. agreed to end the role following 1789 Capital’s reported $300 million investment in Polymarket in August 2026. Trump Jr. received about $300,000 in Kalshi equity after becoming an adviser in January 2025 and may still have a financial stake; Kalshi was later valued at $22 billion and is reportedly discussing a funding round valuing it at $65 billion. The CFTC has sued 11 states seeking to block their regulation of prediction markets and has supported Kalshi in state cases, while the company’s chief executive has acknowledged concerns about the optics of Trump Jr.’s involvement.
