NYSE Owner Invests in Polymarket

Intercontinental Exchange (ICE), which owns the New York Stock Exchange, is said to be investing $2 billion in Polymarket, an Ethereum‑based prediction market. Tabarrok says NYSE will use Polymarket data to sharpen forecasts, and points to decision‑market pilots like conditional markets on Tesla’s compensation vote. — Wall Street’s embrace of prediction markets could normalize market‑based forecasting and decision tools across business and policy, shifting how institutions aggregate and act on information.
