“Groupon, the Chicago-based group buying service and chief rival of DC-based LivingSocial, could be valued as high as $25 billion when it prices its initial public offering (IPO), which could happen later this year, Bloomberg reported. Chevy Chase-based New Enterprise Associates (NEA) has a 20% stake in the company, and Ted Leonsis, the owner of the Wizards and Capitals, as well as the vice chairman emeritus of AOL, is an early backer of the company. Citing two people with knowledge of the situation, the news service said the two-year-old company would likely be valued at a minimum of $15 billion,” according to Potomac Tech Wire.
