Intercontinental Exchange Inc.'s New York Stock Exchange (NYSE) is in talks to buy the Chicago Stock Exchange (CHX), the Wall Street Journal reported on Friday, a month-and-a-half after U.S. regulators blocked the sale of CHX to China-based investors.

NYSE may pay about $70 million for CHX, the Journal reported, citing people familiar with the matter.

CHX and NYSE did not respond to a request for comment outside regular business hours.
