A £1 billion pound damages claim will be filed today (7th June 2024) against Amazon on behalf of retailers selling on Amazon's UK marketplace for illegally misusing their data and manipulating the Amazon Buy Box to benefit its own commercial operation and its overall revenues and profit. The claim, the biggest collective action ever launched by UK retailers, is being brought by the British Independent Retailers Association (BIRA) on behalf of retailers at the Competition Appeal Tribunal (CAT) in London. It asserts that between October 2015 and the present date, Amazon used data belonging to UK retailers on the company's marketplace – data that is non-public and belongs solely and specifically to the retailers – in combination with manipulating the Amazon Buy Box, to engage in a product entry strategy that resulted in sales revenue and profits being diverted from these retailers to Amazon.
