According to CoinMeta, the predictive market platform Kalshi announced the end of its advisory relationship with Donald Trump Jr. This move was due to Trump Jr's venture capital company 1789 Capital increasing its investment in competitor Polymarket. A spokesperson for Kalshi stated that the two parties began discussing the termination of the advisory role in August. Trump Jr's company played a leading role in Polymarket's $1 billion financing round, which is expected to raise the valuation of Polymarket to $21 billion.
