The UK's Competition and Markets Authority (CMA) is probing Microsoft and Amazon for their partnerships with AI startups.

The investigations focus on potential competition issues within the AI sector.

The CMA is calling for feedback from interested parties to inform its decision on a possible antitrust investigation.

Previous inquiries have examined Microsoft's and Amazon's control over the cloud market.

Concerns center around the tech giants' practices of investing in startups, possibly limiting access to computing power and data.

The CMA highlights the risk of such investments affecting vital industries like energy, transport, finance, and healthcare.

Stakeholders have until May 9, 2024, to submit their comments to the CMA.
