NEW YORK (AP) - Shares in the company that runs the New York Stock Exchange are surging amid reports that it is in talks to sell itself to a rival stock exchange.
The Wall Street Journal and CNBC are reporting that Atlanta-based IntercontinentalExchange Inc. is in talks to acquire NYSE Euronext Inc.
The reports published late Wednesday cite unnamed persons close to the discussions who say official word of a deal could emerge as early as Thursday.
NYSE declined to comment. IntercontinentalExchange did not immediately respond to a message seeking comment.
NYSE's stock is up 21 percent in after-hours trading.
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.
