GoKawiilDonald Trump Jr. steps down as Kalshi advisor amid Polymarket investment
Kalshi has ended Donald Trump Jr.'s role as a strategic advisor, saying the two sides mutually agreed to part ways after his venture firm, 1789 Capital, poured $300 million into rival prediction market Polymarket. Trump Jr. had received roughly $300,000 in Kalshi equity when he joined as an advisor in early 2025, a stake that has since grown substantially as Kalshi's valuation rose to $22 billion, with talks reportedly underway for a $65 billion round.
GoKawiil's interpretation of the reporting above, not reported fact.
The split highlights the tangled financial ties within the Trump family's growing footprint in prediction markets, an industry that has expanded rapidly under friendlier federal regulation during the Trump administration. Kalshi's acknowledgment that advising two direct competitors was 'complicating things' suggests the arrangement had become difficult to justify publicly, even as Trump Jr. may retain a financial stake in both platforms. The episode could draw further scrutiny to how politically connected figures are benefiting from a sector the administration has actively supported.
- Kalshi and Donald Trump Jr. mutually ended his advisory role this fall.
- The split followed 1789 Capital's $300 million investment in Polymarket, Kalshi's rival.
- Trump Jr. still holds Kalshi equity granted in 2025, now worth far more after its valuation surged to $22 billion.
