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.
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.
What’s next? DC’s suit will certainly not be the last—New York and California’s probes are still ongoing, for example. And while the bulk of investigations so far relate to its core ecommerce business, there are other parts of Amazon’s business that are rapidly expanding that could draw further regulatory scrutiny down the line. The business made official its purchase of MGM yesterday, for example, and is reportedly looking to expand into physical pharmacies after it opened its online pharmacy in November 2020. Plus, as Amazon becomes part of the digital advertising tripoly alongside Facebook and Google, it could also face scrutiny there, especially given how connected its ad business is with its retail ecommerce business.
