(Sharecast News) - The Competition and Markets Authority said on Friday that it had cleared Amazon's artificial intelligence partnership with San-Francisco based AI start-up Anthropic.

The watchdog said in a brief statement: "The CMA has decided that Amazon's partnership with Anthropic does not qualify for investigation under the merger provisions of the Enterprise Act 2002."

Amazon announced last year that it would invest up to $4bn in Anthropic, which has created a rival to ChatGPT called Claude, and have a minority ownership position in the company.

It said at the time that Amazon developers and engineers would be able to build with Anthropic models via Amazon Bedrock "so they can incorporate generative AI capabilities into their work, enhance existing applications, and create net-new customer experiences across Amazon's businesses".
