Third-party sellers have long accused Amazon's rent-seeking behaviour like steadily increasing cost of doing business on their platform, abusing their dominant market position to manipulate pricing, copying popular products of third-party retailers, and unjustifiably promoting its own brands. In October 2021, based on several leaked internal documents, Reuters reported that Amazon systematically harvested and studied data about their sellers' products' market performance, and used those data to identify lucrative markets and ultimately launch Amazon's replacement products in India. The data included information about returns, the sizing of clothing down to the neck circumference and sleeve length, and the volume of product views on their website. Rivals' market performance data are not available to Amazon's sellers. The strategy also involved tweaking the search results to favor Amazon's private-label products. The Solimo Strategy's impact had a reach well beyond India: hundreds of Solimo branded household items, from multivitamins to coffee pods, are available in the US. One of the victims of the Solimo Strategy is the clothing brand John Miller, owned by India's 'retail king' Kishore Biyani. In October 2022, a £900 million class-action lawsuit was filed in the United Kingdom against Amazon, over a "Buy Box" feature on its website which "favours products sold by Amazon itself, or by retailers who pay Amazon for handling their logistics".

This investigation was concluded in May 2017 when the Commission adopted a decision which rendered binding Amazon's commitments not to use or enforce these clauses. In July 2019 and in November 2020, the European Commission opened two in-depth investigations into Amazon's use of marketplace seller data as well as possible preferential treatment of Amazon's own retail offers and those of marketplace sellers that use Amazon's logistics and delivery services. It charged that Amazon systematically relies on nonpublic data it gathers from third party sellers to unfairly compete against them, to the benefit of its own retail business, thus violating competition law in the European Economic Area. On June 11, 2020, the European Union announced that it will be pressing charges against Amazon over its treatment of third-party e-commerce sellers. The state of California opened an investigation around the same time. In December 2019, the Competition Commission of India suspended an
