UK competition watchdog opens Microsoft probe, wins cloud fee pledges

The UK Competition and Markets Authority opened a strategic market status investigation into Microsoft's business software ecosystem starting in May 2026, and secured commitments from Microsoft and Amazon on cloud data egress fees and interoperability.

Verified GOV.UK (Competition and Markets Authority) press release, 31 March 2026

What it does not test. Does not establish that Microsoft has been found to hold strategic market status, since that determination follows the investigation opening in May 2026.

How this item counts. No movement: no answer to who owns, who operates, whose law governs or who made the parts changes. Weight 0. Fee/interop pledges ease switching but don't change who owns/runs the clouds. European Sovereignty Index
