Intercontinental Exchange, the Atlanta-based parent company of the New York Stock Exchange, is investing up to $2 billion in Polymarket, a prediction platform where users can bet and sell shares on potential outcomes to global events, the companies announced Tuesday.

It’s a match between two companies that on the surface seem wildly different, but are essentially market makers. Polymarket is a disruptive 5-year-old startup where people around the world bet billions of dollars on questions such as when the U.S. government shutdown will end or who will win the Super Bowl. Users can also sell their “yes” or “no” bet, a bit like trading a share in a company.

Polymarket is now considered in some ways a modern-day Nostradamus. The company, along with its rival prediction markets, skyrocketed to prominence after last year’s U.S. presidential election when millions of people bet that Donald Trump would win, resulting in a forecast that was more accurate than some polls. The company is valued at approximately $8 billion.
