The CMA opens its fourth Strategic Market Status case into Microsoft
What happened
The UK’s Competition and Markets Authority (CMA) has launched its fourth Strategic Market Status (SMS) investigation into Microsoft. This new inquiry revisits Microsoft’s core business software products, including Windows, Office, Teams, and its relatively new Copilot AI feature, alongside server operating systems and cloud licensing practices. The probe unfolds after the CMA flagged concerns about Microsoft’s market power last July. The investigation will last nine months, targeting a decision on whether to designate Microsoft with SMS by February 2027. The cloud services component links directly to CMA’s recent cloud market inquiry, making it the first SMS case to extend from that wider investigation.
Why it matters
The CMA’s SMS designation enables the regulator to impose stricter rules on companies it views as strategically dominant. For Microsoft, this means increased scrutiny around how it bundles its products, licenses cloud infrastructure, and integrates AI features like Copilot into its widely used software suites. Builders and buyers relying on Microsoft products should anticipate potential shifts in licensing terms, pricing, or interoperability requirements. For investors and operators, the probe raises the risk of regulatory constraints that could slow Microsoft’s cloud and AI expansion in the UK market or force it to open key technologies more broadly. The cloud licensing angle signals the CMA’s focus on how Microsoft’s hybrid cloud contracts might lock in customers or raise switching costs, which can stifle competition and innovation.
What to watch next
Watch for detailed findings from the ongoing investigation, especially on Microsoft’s AI deployment within Office and Teams, where Copilot could reshape competitive dynamics. Any CMA decision to grant Microsoft Strategic Market Status will change incentives, potentially leading to enforced access or behavioral remedies aimed at limiting bundling and exclusivity. Operators dependent on Microsoft cloud services should consider the possibility of altered contract terms or increased costs. The wider technology sector should track whether this intensifies regulatory scrutiny of other major cloud and AI providers operating in the UK and Europe, as Microsoft’s case may set a precedent for market power interventions aimed at AI-driven product ecosystems.
