eBay Posts Record $13M In Gross Mobile Sales On Sunday, Up 38 Percent Over Cyber Monday

While Black Friday and Cyber Monday are traditionally the largest shopping days in terms of retail sales, eBay is proving otherwise.  The auction site said today that Sunday was the company’s largest day ever in terms of gross merchandise value (also known as GMV, the total sales dollar value for merchandise sold through eBay) via mobile devices.

eBay’s GMV grew 165% globally to $13M on Sunday alone, with $5M of that just in the US — up 127%.  Surprisingly, eBay’s mobile sales were up 38% over Cyber Monday, with its best performing products being clothing and accessories, followed closely by cars & trucks.

The top five U.S. states by sales volume were California, Pennsylvania, Florida, Indiana, and Ohio, according to the company.  At the peak of yesterday’s shopping frenzy in the U.S. (1:00 p.m. to 4:00 p.m. EST), eBay saw more than 9,500 transactions per hour.

eBay has been ramping up substantially to capitalize on this year’s holiday shopping season, with heavy promotion of its updated suite of mobile applications — which collectively have been downloaded more than 30 million times.  The company’s flagship iPhone application has been downloaded over 13 million times alone.  The company issued projections stating it anticipates over $1.5B in mobile transactions in 2010, and it looks like things are well on track to meet that lofty goal.
