eBay identified its top-10 selling markets in the US. Sellers in Los Angeles, New York, Chicago, Philadelphia, Dallas, Orange County, California, Washington DC, Houston, Nassau-Suffolk NY, and Fort Lauderdale FL, generated over $7 billion in Gross Merchandise Volume in 2007, accounting for 55 percent of all sales by US-based eBay sellers.

The survey examined eBay seller transactions between the period of January 1, 2007, and December 31, 2007. The top 10 markets were then determined using a weighted measure that took into account the number of sellers, quantity of items sold and amount of sales generated within each market.

The number-one market for sellers was Los Angeles-Long Beach, California, where 196,089 Los Angeles residents sold 24,051,645 items for a total of $1,396,037,518. Best-selling categories for Los Angeles sellers were cell phones and their accessories as well as clothing and accessories. Los Angeles sellers were also the most charitable eBay sellers last year, donating the most of any city via eBay Giving Works, eBay's program that helps people buy and sell for a cause.
