Amazon offers to change Marketplace rules

Amazon has offered to change the way it treats third-party sellers using its Marketplace platform in the UK, by submitting proposed commitments to the Competition and Markets Authority (CMA) in response to competition concerns it raised with the technology giant.

The CMA considers that these commitments – if accepted – will ensure third-party sellers’ product offers have a fair chance of being prominently displayed to customers in the ‘Buy Box’ on a product page when they are competing against Amazon’s own product offers. The commitments also aim to prevent Amazon from using data that it obtains from third-party sellers to give itself an unfair competitive advantage.

The CMA launched an investigation in July 2022 into concerns that Amazon was abusing its position as the UK’s leading online retail platform by giving an unfair advantage to its own retail business over competing sellers that use Amazon Marketplace, or to sellers that use Amazon’s own warehousing and delivery services, rather than rival organisation businesses.

The CMA’s preliminary view is that the offer from Amazon addresses its competition concerns, and the CMA is now consulting on the commitments put forward before deciding whether to accept them.

The commitments offered propose to:

• Ensure Amazon does not use rival sellers’ Marketplace data to gain an unfair advantage over other sellers. This follows concerns that Amazon’s access to commercially sensitive data relating to third-party sellers helped its retail business to decide which products to sell, manage stock levels for those products, set prices and make other important commercial decisions.
• Guarantee all product offers are treated equally when Amazon decides which will be featured in the ‘Buy Box’. This relates to concerns that products being offered by third-party sellers were less likely to appear in the Buy Box than similar offers from either Amazon’s own retail business or third-party sellers that use Amazon’s delivery services.
• Allow third-party businesses using Marketplace to negotiate their own rates directly with independent providers of Prime delivery services so that customers can benefit from lower delivery costs where better rates are negotiated.
• Require Amazon to appoint an independent trustee who will monitor the company’s compliance with these commitments. The CMA will have a direct say in this appointment, ensuring they have the necessary skills and expertise for the job.
