UK Regulator to Scrutinize Microsoft's Software Licensing and AI Strategy

Investigation Details

• Starting in May, the U.K. Competition and Markets Authority will examine Microsoft's business software ecosystem following a Tuesday statement from the regulator. The probe will assess whether the company's approach to software licensing creates barriers to competition in the cloud sector, particularly as worries mount about AI capabilities locking customers into Microsoft's platform.
• Should the investigation result in a strategic market status designation—a classification under the Digital Markets, Competition and Consumers Act that identifies technology firms with substantial market power—the CMA would gain authority to address Microsoft's licensing approach and create more equitable conditions as AI becomes integrated into business software, according to CMA chief executive Sarah Cardell's announcement.
• Following prior discussions with the CMA, both Microsoft and Amazon have outlined strategies to lower cloud switching expenses and enhance compatibility between platforms. According to the CMA, these measures aim to "reduce expense and effort for U.K. customers when using more than one cloud provider."

Market Context and Competitive Concerns

Microsoft's suite of business applications—spanning productivity software, operational platforms and data management systems—has become deeply embedded in enterprise environments globally. With the company now weaving AI capabilities throughout its workplace applications, regulatory bodies are increasingly focused on the risk of vendor lock-in.

The CMA emphasizes that artificial intelligence's potential to drive productivity gains, enhance competitiveness and reduce expenses is substantial given the rapid pace of adoption. The regulator contends that U.K. enterprises would be best served by a competitive landscape "where a broad range of competitors can integrate with Microsoft's business software, so that business and public sector organizations can mix-and-match AI software across suppliers to best suit their needs."

In December, Microsoft announced plans to increase pricing for its core subscription offerings, with rates rising approximately 16% beginning in July 2026 to reflect the addition of expanded AI capabilities. Meanwhile, enterprise adoption of artificial intelligence is already driving substantial quarterly revenue increases for the three dominant cloud vendors—AWS, Microsoft and Google, according to research from Omdia.

Microsoft's cloud segment expanded 39% during the fourth quarter of 2025. AWS experienced 24% growth during the same period, while Google achieved nearly 50% expansion, based on the firms' respective quarterly earnings disclosures.

Microsoft's Response and Industry Perspective

Addressing the U.K. inquiry, Microsoft stated it remains "committed to working quickly and constructively" with the CMA regarding the agency's concerns, as communicated by Vice Chair and President Brad Smith in a Tuesday blog post.

The cloud and AI markets continue to change at an unprecedented pace. The cloud market itself remains intensely competitive, with large investments by Amazon, Google, Oracle and new neocloud entrants.

Without regulatory intervention requiring immediate action, Microsoft will "continue to further entrench its dominance in AI just as it has in software and cloud," according to Ryan Triplette, executive director of the Coalition for Fair Software Licensing.

The CMA's decision is among one of the most significant structural interventions to date, and provides real opportunity for U.K. businesses and the public sector organizations that have absorbed Microsoft's price increases, navigated its policy changes, and watched their bottom line shrink while their options narrowed.
