The company says the offering of 42.2 million shares priced at 20 euros per share, near the low end of its expectations.
Euronext NV operates exchanges in Paris, Amsterdam, Brussels and Lisbon. Its stock will begin trading in Paris, Amsterdam and Brussels under the symbol "ENX" on Friday. Euronext says it will list in Lisbon later.
Euronext merged with the New York Stock Exchange in 2006, and Atlanta-based IntercontinentalExchange Group Inc. bought the combined company for about $8 billion in November.
The underwriters of the IPO will have the option to buy another 4.2 million shares to cover any over-allotments.
