Groupon files for IPO of up to $750 million

NEW YORK (Reuters) - Online coupon company Groupon Inc filed for an initial public offering on Thursday, the latest in a series of social networking companies to tap the U.S. capital markets.

Groupon filed to raise up to $750 million in its IPO. However that figure is preliminary and could change.

The filing did not specify the number of shares to be sold in the IPO, the price range, or the exchange, though it did say the shares would trade under the symbol "GRPN."

Underwriters are being led by Morgan Stanley and Goldman Sachs & Co.
