Microsoft is facing a potentially larger antitrust signal as the Federal Trade Commission examines whether the company used unfair methods of competition across cloud, software and related services.

The investigation centers on civil investigative demands sent to at least half a dozen companies that compete with Microsoft.

The requests indicate FTC interest in Microsoft Azure, licensing arrangements, interoperability, bundling, pricing, discounting, profitability and the company’s role in AI products.

The probe began in 2024 under the Biden administration and continued under President Donald Trump.

No legal complaint is guaranteed.

FTC staff would still need to decide whether to recommend a case, and the agency’s two commissioners would have to vote on whether to sue.

Microsoft says it is cooperating with the FTC and argues that its practices promote competition while delivering products customers expect.

Why it matters

The signal is that Microsoft’s cloud and AI position is drawing closer scrutiny after years in which other large technology companies faced more direct breakup pressure.

Azure is important not only as a cloud business, but also as infrastructure for AI workloads.

If regulators focus on licensing terms, bundling or interoperability, the outcome could matter for enterprise software buyers, cloud rivals and companies building AI products on top of major platforms.

The investigation also arrives as cloud growth has helped push Microsoft’s valuation to historic highs and positioned the company for AI computing demand.

That makes the regulatory question commercially sensitive: the FTC appears to be testing whether Microsoft’s software position gives Azure or Microsoft-linked AI products an unfair advantage, rather than simply asking whether the company is large.

The competitive questions

The FTC questions described in the source ask companies for organizational charts, business and marketing plans, product roadmaps and documents on barriers to entering or expanding in markets where Microsoft operates.

The agency also asks about competition around AI products, including situations where businesses combine additional features or services with an AI or software product such as Microsoft 365.

The issue is not limited to the United States.

The UK Competition and Markets Authority and the Japan Fair Trade Commission have also examined Microsoft’s cloud services within the last year.

Microsoft says it is cooperating with those reviews.

What to watch next

Readers should watch whether FTC staff recommend a complaint, whether the two commissioners vote to proceed, and whether any case targets Azure licensing, bundling, interoperability or AI-related tying theories.

A lawsuit would not automatically mean a breakup, but it could create years of litigation and affect how cloud and AI platform providers structure commercial terms.
