New York Stock Exchange parent company Intercontinental Exchange has completed its investment in the popular market prediction platform Polymarket, with a total of $1.6 billion.
ICE said the new funding is part of Polymarket’s fundraising efforts, and that the company intends to buy up to $40 million worth of Polymarket securities from existing investors.
