The United States is the largest and most competitive Amazon marketplace globally, with over 300 million active customer accounts and more than 2.5 million active third-party sellers. As the original Amazon market, it sets the benchmark for FBA operations worldwide.

Market Characteristics

Amazon.com dominates U.S. e-commerce with approximately 38% market share. The marketplace processes an estimated $574 billion in annual gross merchandise volume, making it the single largest product search engine in the country — surpassing Google for product discovery queries.

Average revenue per seller varies dramatically by category, but successful FBA sellers in competitive niches typically generate $50,000 to $500,000 annually. The market rewards deep category expertise and sophisticated PPC strategy.

Competitive Landscape

Competition in the U.S. market is the most intense globally. Top categories like Electronics and Home & Kitchen feature thousands of listings per sub-niche, with established brands and experienced Amazon-native sellers. New entrants should expect higher PPC costs (average CPC of $0.80-$1.50 depending on category) and longer break-even timelines compared to emerging markets.

Review velocity matters significantly — products with fewer than 50 reviews struggle for visibility in most competitive niches. Our analysis identifies sub-niches where competition metrics are favorable for new entrants.

FBA Fee Structure

The U.S. marketplace serves as the baseline (1.0x multiplier) for FBA fee calculations. Referral fees range from 6% to 45% depending on category, with most categories at 15%. Fulfillment fees are weight-and-size based, starting at $3.22 for small standard items. Storage fees increase seasonally, with Q4 rates approximately 3x higher than non-peak periods.
