The news: The District of Columbia attorney general sued Amazon Tuesday, May 25, over accusations that it used its marketplace dominance to artificially inflate prices.
More on this: The suit claims Amazon imposes sanctions on third-party products if they’re listed for cheaper on other websites, forcing merchants to either increase their prices on other marketplaces or sell exclusively through Amazon. It was filed in district—not federal—court, which means any ruling would only apply to DC. Still, it’s significant because it’s the first of what will likely be many US antitrust cases against Amazon.
How we got here: Amazon’s relationship with third-party sellers has been under the microscope for years, and scrutiny has only ramped up over the last year as Amazon’s ecommerce business boomed during the pandemic.
- Jeff Bezos was called before Congress for the first time in July 2020, where the House Judiciary Committee questioned him over allegations that Amazon mined third-party sellers’ data to develop competing products.
- Shortly after, the Federal Trade Commission and the New York and California attorneys general announced plans to investigate Amazon’s third-party marketplace.
- In November 2020, the European Commission filed a formal complaint against Amazon for the same allegations, the first of such antitrust charges worldwide.
- DC’s new suit addresses the same segment of Amazon’s business, though the complaint focuses on anti-competitive pricing policies rather than use of third-party merchants’ data.
Key stat: Amazon’s third-party marketplace will make up 60.0% of its US ecommerce sales this year, or $220.39 billion, per our estimates. And because Amazon’s market share is so large, its third-party marketplace alone makes up nearly a quarter (24.3%) of total US retail ecommerce sales. We expect both its sales and share of the market to keep growing next year.
