The Competition and Markets Authority (CMA) is seeking feedback on potential competition breaches involving high-profile partnerships between Microsoft, Amazon, and other tech and AI firms. Microsoft’s collaboration with Mistral AI, Amazon’s investment in Anthropic, and Microsoft’s hiring of Inflection AI talent are under investigation. The CMA is concerned about a web of alliances and investments that could lead to an unhealthy concentration of power in the AI industry. Foundation Models have the potential to significantly impact various sectors of the UK economy, and the CMA is committed to ensuring fair competition in this space.
