CMA Launches In-Depth Investigation into Microsoft’s Market Practices

Published on May 14, 2026

The UK’s Competition and Markets Authority (CMA) has been scrutinizing major tech players for several years. Microsoft, with its extensive suite of products from Windows to cloud services, was already on the radar. Recent discussions suggested a growing concern over its dominance in the cloud market.

The CMA’s investigation will explore Microsoft’s cloud licenses and its interconnected services. This inquiry is unique, as it directly stems from the September 2026 inquiry into the cloud market, indicating a proactive approach . The findings could shape how Microsoft operates within the UK, particularly concerning its business software solutions.

If the CMA concludes that Microsoft holds an unfair market position, significant repercussions could follow. Potential auctions of existing licenses or new regulations may emerge, impacting both Microsoft and its competitors. This investigation represents a pivotal moment in the ongoing efforts to ensure fairness within the tech ecosystem in the UK.
