Three exchange companies are considering individual bids for Euronext, the European exchange group set to be spun off after it was acquired last week by IntercontinentalExchange Group, according to people familiar with the discussions.

London Stock Exchange Group, Nasdaq OMX Group and Deutsche Börse each have discussed with advisers the possibility of making offers for Euronext, although none has hired bankers to launch a formal bid, the people said. It is possible the potential suitors won't move forward at all, given other priorities and challenges.
