The next big thing in consolidation brings us this week’s Marketplace Money buzzword: Euronext.

Euronext is a European company that owns stock exchanges in chic spots like Amsterdam, Lisbon and Paris.

Thanks to stiff competition, stock market mergers are all the rage these days, so it’s no surprise that several exchange companies think Euronext would make a trendy accessory.

This week, the New York Stock Exchange made a stylish offer to buy Euronext, in a stock swap worth more than $10 billion.

If the deal goes through, it would create the world’s biggest international exchange open 22 hours a day.
