NextFin News - The Federal Trade Commission (FTC) has significantly escalated its antitrust investigation into Microsoft Corp., signaling a more aggressive phase in the U.S. government’s oversight of the cloud computing and artificial intelligence sectors. According to Reuters, the agency has recently dispatched detailed questionnaires to Microsoft’s competitors and industry participants, seeking granular information on the company’s commercial conduct. This move, occurring in February 2026, aims to determine whether the Redmond-based giant is leveraging its dominant enterprise software position to stifle competition in the rapidly evolving AI and cloud infrastructure markets.
The probe, which has been quietly gaining momentum for months, is now focusing on specific mechanisms of market control. According to The Information, the FTC is particularly interested in Microsoft’s software licensing practices, which rivals such as Amazon Web Services (AWS) and Google Cloud argue impose a "cloud tax" on customers who wish to run Microsoft software on non-Azure platforms. Furthermore, the investigation is scrutinizing the architectural bundling of Microsoft 365, Azure, and the Copilot AI suite, alongside the company’s exclusive $13 billion partnership with OpenAI. By questioning rivals, the FTC seeks to build a comprehensive evidentiary base to challenge what critics describe as an impenetrable ecosystem designed to lock in enterprise clients.
This regulatory intensification reflects a broader strategic pivot within the FTC under Chair Andrew Ferguson, who assumed the role in early 2025 following the inauguration of U.S. President Trump. While the previous administration’s FTC was noted for its broad-spectrum aggression against Big Tech, Ferguson’s commission appears to be narrowing its focus toward the "gatekeeper" dynamics of the AI supply chain. The current inquiry is not merely a retrospective look at cloud licensing but a forward-looking attempt to prevent the monopolization of generative AI before the market matures. The FTC’s outreach to rivals suggests it is looking for specific instances where Microsoft’s integrated stack has directly foreclosed competitive bids or forced customers into exclusive Azure commitments.
At the heart of the cloud-related grievances is the financial disparity created by Microsoft’s licensing terms. Industry data from 2024 indicated that the global cloud infrastructure market exceeded $270 billion, with Azure holding approximately 25% market share. However, rivals contend that this growth is artificially bolstered by policies that make it significantly more expensive to run Windows Server or SQL Server on competing clouds. According to Seeking Alpha, the FTC is investigating whether these terms constitute illegal tying—a practice where a dominant firm forces customers to purchase a secondary product (Azure) to maintain access to a primary one (Office or Windows).
The AI dimension adds a layer of complexity that traditional antitrust frameworks are only beginning to address. Microsoft’s exclusive cloud-hosting rights for OpenAI’s models mean that any enterprise seeking to utilize GPT-4 or its successors through official channels is effectively funneled into the Azure ecosystem. This "gravitational pull" is a primary concern for Ferguson and the FTC. The agency is probing whether the Microsoft-OpenAI relationship functions as a de facto acquisition that bypassed standard merger review. If the FTC finds that Microsoft’s influence over OpenAI’s strategic direction—highlighted during the 2023 boardroom crisis—amounts to control, it could demand structural changes to the partnership.
Microsoft, led by President Brad Smith, has consistently defended its practices as pro-innovation. Smith has previously pointed to the 2024 settlement with European cloud providers (CISPE) as evidence of the company’s willingness to adapt. In that instance, Microsoft paid approximately €20 million and adjusted certain licensing terms. However, the FTC’s current line of questioning suggests that U.S. regulators view those concessions as insufficient. The agency is likely looking for evidence that the "CISPE template" failed to address the fundamental structural advantages Microsoft enjoys in the domestic market.
Looking ahead, the outcome of this probe could redefine the boundaries of the "integrated ecosystem" model that has dominated the software industry for decades. If the FTC moves toward a formal complaint, it could seek remedies ranging from mandatory licensing parity to the unbundling of AI services from productivity software. For investors, the stakes are high; Microsoft’s $3 trillion market capitalization is heavily predicated on its ability to monetize AI through its existing enterprise footprint. A forced decoupling of these services would not only impact Microsoft’s margins but also provide a significant opening for specialized AI startups and rival cloud providers to capture market share in the enterprise sector.
As the FTC continues to grill rivals, the tech industry is entering a period of heightened regulatory friction. The transition from the Biden-era focus on consumer privacy and social media to the current administration’s focus on AI infrastructure competition suggests that Big Tech’s regulatory challenges are evolving rather than receding. For Microsoft, the challenge is to prove that its "all-in-one" value proposition is a result of superior innovation rather than a calculated strategy to exclude competitors from the most important technological shift of the decade.
