The United Kingdom's Competition and Markets Authority (CMA) has officially launched a probe into Amazon's $4 billion partnership with the AI firm Anthropic, as it continues to monitor how the largest tech companies might seize control of AI to further entrench their dominant market positions.

Through the partnership, "Amazon will become Anthropic’s primary cloud provider for certain workloads, including agreements for purchasing computing capacity and non-exclusive commitments to make Anthropic models available on Amazon Bedrock," the CMA said.
