Nasdaq, Inc. is an American multinational financial services corporation that owns and operates three stock exchanges in the United States: the namesake Nasdaq stock exchange, the Philadelphia Stock Exchange, and the Boston Stock Exchange, and seven European stock exchanges: Nasdaq Copenhagen, Nasdaq Helsinki, Nasdaq Iceland, Nasdaq Riga, Nasdaq Stockholm, Nasdaq Tallinn, and Nasdaq Vilnius. It is headquartered in New York City, and its president and chief executive officer is Adena Friedman. Historically, the European operations have been known by the company name OMX AB (Aktiebolaget Optionsmäklarna/Helsinki Stock Exchange), which was created in 2003 upon a merger between OM AB and HEX plc. The operations have been part of Nasdaq, Inc. (formerly known as Nasdaq OMX Group) since February 2008. They are now known as Nasdaq Nordic, which provides financial services and operates marketplaces for securities in the Nordic and Baltic regions of Europe. History Background 1980–2008: European bourses merged in OMX AB OM AB (Optionsmäklarna) was a futures exchange founded by Olof Stenhammar in the 1980s to introduce trading in standardized option contracts in Sweden.

On August 31, 2004, the brand name of the company was changed to OMX. OMX then acquired the Copenhagen Stock Exchange in January 2005 for €164 million.
