UK initiates antitrust investigation into Microsoft's business software

• The CMA previously identified that the dominance of Amazon and Microsoft was harming competition in cloud computing
• Both Microsoft and Amazon are taking 'material steps' to lower some cloud market fees in response to regulatory pressure
• If Microsoft is designated with 'strategic market status' in business software, the CMA would gain authority to directly act on its software licensing practices

Summary

UK Launches Antitrust Probe into Microsoft's Business Software

The UK's Competition and Markets Authority (CMA) announced on March 31 that it will launch a new antitrust investigation into Microsoft's business software ecosystem beginning in May. The probe will focus specifically on Microsoft's software licensing practices in the cloud computing market.

Background and Key Players:

This investigation follows a 2024 CMA inquiry that found Microsoft and Amazon's dominance was harming competition in the cloud computing sector. Both companies have since taken "material steps" to reduce certain fees in the cloud market, according to the regulator.

Potential Regulatory Impact:

Microsoft could be designated with "strategic market status" in business software as a result of this investigation. Such classification would grant the CMA enhanced regulatory powers to intervene on software licensing practices, potentially imposing stricter oversight and remedies.

Market Implications:

The investigation highlights increasing regulatory scrutiny of Big Tech's cloud infrastructure dominance, particularly around licensing practices that may lock customers into specific platforms. This follows broader global concerns about anti-competitive behavior in cloud services. The probe could result in mandated changes to Microsoft's licensing terms, potentially affecting its cloud revenue streams and competitive positioning against rivals like Amazon Web Services.

The CMA's acknowledgment that both Microsoft and Amazon are making pricing adjustments suggests regulators are pushing for more competitive market conditions. Investors should monitor developments for potential impacts on Microsoft's cloud business model and profitability, particularly if forced structural changes emerge from the investigation.

Timeline: Investigation set to begin May 2025.
