The United Kingdom has started an antitrust investigation into Microsoft’s business software, adding new regulatory pressure on the tech giant.
The Competition and Markets Authority (CMA) will look into whether Microsoft’s role in business software could earn it a “strategic market status.”
This status would let regulators step in if they find Microsoft holds significant market power. Channel News Asia, citing Reuters, said the investigation began on May 14 and is expected to finish by February 2027.
Bundling and AI integration are central issues
The CMA will look at whether Microsoft’s bundling of products like Windows, Word, Excel, Teams, Copilot, and others is making it harder for other companies to compete in the business software market.
Reuters also reported that the regulator will check how well AI competitors can connect with Microsoft’s software. This shows the investigation is not just about office programs, but also about how AI tools can compete within workplace platforms.
The AI aspect matters because Microsoft has been adding Copilot to many of its business products, making its workplace tools a way to spread generative AI.
If other AI companies have trouble connecting to Microsoft’s system on equal terms, the CMA might see Microsoft’s software as a gatekeeper for the future of workplace technology.
New UK powers give the CMA more room to act
CNA shared that this is the CMA’s fourth investigation using new powers given last year. These powers let the regulator examine big digital companies whose services are hard for customers and competitors to avoid. If Microsoft is given the strategic market status, the CMA could set rules or remedies to protect choice, innovation, and fair pricing.
The investigation could affect more than just office software. If Microsoft gets the SMS designation, the CMA could also step in on cloud services.
The regulator has already found that Microsoft’s software licensing might limit competition in the cloud market. This means the case could cover workplace software, AI integration, and cloud competition all at once.
CMA says business software is core to the UK economy
CMA Chief Executive Sarah Cardell said business software is a “cornerstone” of the UK economy, with hundreds of thousands of customers depending on Microsoft’s systems.
She explained that the regulator wants to learn how the market is changing, what role Microsoft plays, and what steps might be needed so UK organizations have access to choice, innovation, and fair prices.
Microsoft has said it will cooperate with the investigation. A company spokesperson stated that Microsoft is committed to working “quickly and constructively” with the CMA during the review of the business software market.
Why this matters for workplace software
This case comes as business software is becoming more bundled, powered by AI, and closely linked to cloud systems.
For many organizations, Microsoft’s tools are not just extras—they are used daily for documents, meetings, communication, spreadsheets, and more AI-supported work. That is why the UK investigation could have effects beyond Britain.
If the CMA finds that Microsoft’s software limits competition, it could influence how workplace AI tools are packaged, connected, and priced in the future.
