Microsoft’s Cloud Dominance Under FTC Microscope as Antitrust Heat Returns

The Quiet Giant Returns to the Hot Seat
For more than two decades, Microsoft has enjoyed a remarkably quiet existence compared to its peers in Big Tech. While Google, Apple, and Meta have spent the last several years besieged by sweeping lawsuits and populist calls for break-ups, Microsoft largely flew under the regulatory radar, transforming itself from the villain of the 1990s browser wars into a cloud-centric powerhouse. That grace period may finally be expiring.
The Federal Trade Commission (FTC) is currently conducting a probe that suggests the agency is closely examining whether Microsoft has revived the exclusionary tactics that defined its early monopoly era. According to internal documents and civil investigative demands (CIDs) reviewed by GizStreet and other industry sources, the FTC is digging deep into Microsoft’s business agreements, licensing arrangements, and the interoperability of its core products.
These CIDs—which function similarly to subpoenas—were dispatched to at least half a dozen companies that compete directly with Microsoft. The goal is clear: the agency wants to determine if the company has employed unfair methods of competition to protect its cloud and software empires in violation of the FTC Act.
The Azure Lock-in Strategy
At the heart of the investigation is Microsoft Azure. While Azure is a technical marvel that has propelled Microsoft’s valuation to historic highs, competitors argue that its growth is partially fueled by aggressive licensing maneuvers. Specifically, the FTC is investigating claims that Microsoft’s 2019 changes to its licensing terms made it prohibitively expensive for customers to run Windows software on competing infrastructure, such as Google Cloud or Amazon Web Services (AWS).
Google has been vocal about these frustrations. In a 2023 response to a broad FTC inquiry, Google accused Microsoft of leveraging its dominant position in productivity software to give Azure an “unearned advantage,” effectively locking consumers into its ecosystem through financial penalties rather than superior product quality.
Microsoft has pushed back against these claims. Company spokesperson Alex Haurek maintains that Microsoft is cooperating fully with the agency and argues that the cloud sector remains fiercely competitive. Haurek pointed to Google’s own growth—reporting a 63% year-over-year increase—as evidence that the market is far from a monopoly.
AI and the New Competitive Frontier
The probe isn’t limited to cloud infrastructure. The FTC is also casting a wide net over the AI industry. The investigative demands include detailed questions about how Microsoft bundles AI features with its existing software suite and how these practices impact the ability of smaller AI startups to compete for customers.
The intersection of cloud and AI is where the stakes are highest. Because AI requires massive computing power, Microsoft’s control over the underlying cloud infrastructure (Azure) gives it a vertical advantage. The FTC is specifically soliciting documents regarding product roadmaps, pricing strategies, and the specific costs associated with entering markets where Microsoft is already entrenched.
This line of questioning echoes a 2024 ProPublica investigation, which alleged that Microsoft used free cybersecurity upgrades to embed its services within U.S. government agencies, creating a dependency on Azure that would be grueling for the public sector to unwind.
The Regulatory Path Forward
Despite the intensity of the information gathering, a formal lawsuit is not guaranteed. The investigation began under the Biden administration and has persisted into the Trump administration, moving through a shift in political leadership. The final decision rests with the FTC’s commissioners, who must vote on whether to file a legal complaint based on the evidence gathered by staff.
William Kovacic, a former FTC Chair and professor at George Washington University, notes that this stage of the process is primarily about information gathering. Because the current commission is composed of Republicans, there is a possibility the probe could end quietly without a public complaint, provided the evidence does not suggest a clear violation of law.
If the FTC does move forward, Microsoft faces a haunting historical parallel. More than twenty years ago, the company fought a grueling legal battle over its PC operating system monopoly. Now, as it seeks to dominate the AI era, the company may find that the regulators have a very long memory.
