Amazon Owns More Than A Third of U.S. E-Commerce, Report Says

Everybody knows Amazon.com is an online giant. Now an analyst has determined just how big a giant: According to RBC Capital Analyst Stephen Ju, Amazon accounts for more than a third of all E-Commerce.

"Using our data, the total GMV (value of all the e-commerce activity flowing through AMZN's platform) is close to $12.5 billion in the U.S., or 34 percent of the $37 billion the U.S. Commerce Department reported for 4Q08," wrote Ju an April 14 report called "How Much Share Does Amazon Really Have?" Ju determined Amazon's piece of the U.S. E-Commerce pie continues to grow. It was 27 percent last year, he wrote.
