NEW YORK (AP) -- Shares of the company that runs the New York Stock Exchange and a rival exchange have been halted in premarket trading amid reports that one of the most prominent symbols of global capitalism may be up for sale.
The Wall Street Journal and CNBC are reporting that IntercontinentalExchange Inc. is in talks to buy NYSE Euronext Inc.
The reports published late Wednesday cited unnamed persons close to the discussions.
NYSE declined to comment. IntercontinentalExchange did not immediately respond to a message seeking comment.
NYSE's stock is rose 21 percent in after-hours trading Wednesday.
Last year, IntercontinentalExchange and Nasdaq OMX Group Inc. made a failed $11 billion bid to buy NYSE Euronext.
Earlier this year, European regulators blocked Deutsche Boerse AG from buying NYSE Euronext.
