Discount coupon site Groupon has filed the forms for its much-anticipated initial public offering (IPO).
The company said that it will go public later this year to raise $750m (£459m) in stock sales. The number of shares and the selling price have yet to be determined.
Groupon's IPO was said to be a foregone conclusion after the company turned down a $6bn acquisition offer from Google in December.
The search firm has since been reported as developing a competitor to Groupon known as Google Offers, while Facebook and other companies have also started coupon services.
The IPO will make Groupon the second major social networking firm to enter the US market this year. Professional social networking site LinkedIn went public in May with an IPO that valued the company at $4.9bn.
Rob Enderle, principal analyst at the Enderle Group, said that Groupon's IPO will allow the company to fend off challengers such as Google Offers, but that the sale is another indication of a bubble forming in the social networking space.
"There is still a feeding frenzy surrounding this class of product," he told V3.co.uk. "It is a very good time to go public with social networking-type companies. There are buyers out there who want these properties."
