European Union regulators are deepening their examination of Microsoft’s market power, broadening an existing antitrust review to include the company’s cloud computing business and its investments in artificial intelligence, according to Reuters.

The European Commission is assessing whether Microsoft’s position in cloud services gives it an unfair advantage and whether its AI-related deals could reinforce that dominance. The review marks a wider look at how the software giant competes across fast-growing digital markets that are increasingly shaped by cloud infrastructure and AI tools.

Microsoft has faced growing regulatory pressure in Europe and elsewhere over concerns that large technology companies can use their scale, data, and bundled services to lock customers into their platforms. The new scrutiny suggests EU officials want to understand not only Microsoft’s traditional software business, but also how its newer AI ambitions may affect competition.

The company’s cloud and AI strategy has become central to its growth story, but it is also drawing sharper oversight as regulators try to prevent entrenched players from limiting rivals. The investigation is ongoing, and EU officials have not yet announced any enforcement decision.
