On 1 April 2026, the UK Competition and Markets Authority confirmed a formal antitrust probe into Microsoft’s business software and cloud licensing practices in the UK. The investigation will look at whether Microsoft’s bundling and licensing terms for products such as Office 365 and Azure make it harder or more expensive for rival providers to compete, which could affect costs and choice for UK firms that rely on cloud and productivity tools. This is the second major CMA investigation into Microsoft’s cloud-related conduct, raising questions over how far large software vendors can tie their services together in the UK market.

Global tech scrutiny
Chinese coverage presents the CMA investigation as part of a global tightening of rules on large US tech firms, especially in cloud and software. Reports stress that Microsoft is now facing a second major UK probe, suggesting that regulators are increasingly worried about how its licensing affects smaller cloud providers. Commentators expect more countries to watch the UK case as they consider their own rules for cloud services and software bundling.
- •Chinese reports state that the CMA’s new case adds to Microsoft’s existing UK cloud investigation.
- •Coverage notes that European regulators have already questioned Microsoft’s cloud licensing terms after complaints from local providers.
- •Commentary argues that the UK action shows regulators are more willing to confront US tech firms over market dominance.
- •Reports suggest that smaller cloud providers see the case as a chance to gain fairer access to customers.
- •Some coverage predicts that other jurisdictions may study the CMA’s findings when shaping their own cloud competition rules.
OFFICIAL
Protecting UK competition
UK regulators present the probe as a response to concerns that Microsoft’s software and cloud licensing may be shutting out rivals and harming UK business customers. The CMA says it wants to ensure that large vendors cannot use their strength in one product, such as Office, to lock customers into their wider cloud ecosystems. Officials expect the investigation to clarify what changes, if any, are needed to keep the UK cloud and business software market open and competitive.
- •The CMA investigation will assess whether Microsoft’s bundling of Office 365, Teams and Azure restricts competition from rival cloud and productivity providers.
- •UK regulators argue that complaints from other cloud providers justify a closer look at Microsoft’s licensing rules.
FINANCE
Regulatory risk for Microsoft
Financial outlets frame the CMA probe as another layer of regulatory risk for Microsoft’s cloud and productivity businesses, which are key drivers of its revenue and valuation. Investors are watching whether the case leads to fines, forced product unbundling, or changes to licensing that could slow growth or help rivals like Amazon, Google and smaller European providers. Market commentary also links the UK action to a broader pattern of tougher competition enforcement against large US tech firms in Europe.
- •Market commentators warn that a negative CMA finding could force Microsoft to unbundle some software and cloud services in the UK.
- •Investors note that repeated competition probes in the UK and EU may limit how aggressively Microsoft can tie products together.
