Goldman Sachs CEO said the bank is exploring opportunities to predict the market.

Goldman Sachs Group is paying attention to the opportunities in prediction markets, which will allow this investment bank to benefit from the rapidly growing field of betting on real-world events. The company's CEO David Solomon called prediction markets "extremely interesting" and said that he personally met with the leaders of the two largest prediction market companies in the past two weeks. Solomon said in a call with analysts on Thursday after the bank announced its fourth-quarter earnings, "We have a team that will spend time communicating with them and studying this matter." Mainstream Wall Street firms entering the prediction market could enhance the legitimacy and trading volume of this loosely regulated but thriving financial sector. Some market-making companies have already joined the fray.
