New York ― If Groupon goes public with a valuation of $25 billion, it will be the largest IPO by a venture-backed company, according to Dow Jones VentureSource. Google’s public offering, which had a valuation of $24.6 billion in 2004, is currently the largest venture-backed IPO in history.

If Groupon’s valuation lands closer to $15 billion, which is the low end of industry participants’ estimates, it would still become part of an elite group of venture-backed companies that held public offerings valued above $10 billion.

Four venture-backed companies have achieved a valuation above $10 billion at their IPO. They are:

1. Google (Mountain View, Calif.) - $24.6 billion valuation in 2004

2. Huatai Securities Co. (Nanjing, China) - $16.4 billion valuation in 2010

3. Corvis (Columbia, Md.) - $14.2 billion valuation in 2000

4. Sinovel Wind Group Co. Ltd. (Beijing, China) - $13.7 billion valuation in 2011
