Intercontinental Exchange Pumps an Additional $600 Million into Polymarket Amid Rising Prediction Market Volume

The Intercontinental Exchange (ICE), which owns the New York Stock Exchange, has invested a further $600 million into Polymarket, a leading player in the crypto-based prediction markets. This comes in the wake of Polymarket's rival, Kalshi, securing a $1 billion investment, taking its company valuation to $22 billion. To date, ICE's total investment in Polymarket amounts to around $2 billion, its first pre-money investment having been made in October 2025. This substantial investment not only offers operational capital to the company but also legitimizes prediction markets as a viable source of crowd-sourced event probabilities that institutional users could potentially utilize far beyond simple betting.
