NextFin news, On November 18, 2025, the European Commission, the EU's digital regulatory authority, announced the initiation of twin investigations into Amazon Web Services (AWS) and Microsoft Azure. These probes aim to assess whether these two US-based cloud computing giants should be designated as gatekeepers under the EU's Digital Markets Act (DMA). The announcement was made by the European Commission's tech chief Henna Virkkunen during a summit in Berlin, highlighting an intensified push for European digital sovereignty amidst growing concerns around the dominance of US cloud providers in the 27-nation bloc.
The DMA targets digital platforms that act as vital gateways between businesses and consumers. Traditionally, gatekeeper status is assigned based on criteria like size, market position, and monthly active users. However, the Commission is investigating AWS and Azure despite these services not meeting the conventional size and user number thresholds. The focus is on whether these cloud providers exert significant gateway control in the cloud computing sector, which holds strategic importance for European business competitiveness.
Alongside the individual investigations, the Commission has opened a third market probe to evaluate whether the DMA framework itself requires updating. This investigation targets issues such as interoperability constraints, data access limitations, bundling of cloud services, and potentially imbalanced contractual terms that could restrict fairness and competition in Europe's cloud market. The Commission aims to conclude all investigations within the next 12 months.
Amazon and Microsoft, key leaders in the cloud market—AWS being the global frontrunner with around two-thirds market share in Europe, followed by Microsoft Azure—have expressed confidence that the dynamic, innovative, and competitive nature of the cloud sector will be recognized. AWS emphasized that imposing gatekeeper rules could stifle innovation and inflate costs, which would be detrimental to European companies.
The European Commission's concerns are partly driven by recent events: widespread service outages affecting Microsoft Azure clients in October, including key disruptions to Alaska Airlines, and previous Amazon AWS outages that forced popular streaming platforms and messaging apps offline for extended periods. These incidents have intensified scrutiny over reliance on a few dominant cloud providers, accentuating risks to operational resilience and data sovereignty.
The DMA empowers the EU to impose fines up to 10% of a company's global turnover if found to undermine market fairness or competition. This regulatory muscle was previously applied to other services of the companies involved, such as Amazon's Marketplace and Microsoft's LinkedIn platform, where stricter rules have been imposed.
The investigation aligns with broader EU policy ambitions to bolster digital autonomy, diversifying tech dependencies and enforcing fair competition. Notably, Google Cloud, which ranks third in market share, is not under investigation, possibly reflecting a strategic focus on the largest gatekeepers.
Analytically, the Commission’s move underscores increasing geopolitical and economic tensions in digital infrastructure control, especially between the EU and US tech behemoths. Deploying the DMA in the cloud sector marks a novel regulatory frontier—cloud services serve as foundational platforms for digital transformation, AI deployment, and data management across industries. Tightening regulations on gatekeepers could drive architectural shifts in the sector, pushing for enhanced interoperability standards, greater data portability, and a more level playing field for European cloud providers.
With the cloud market projected to sustain high growth—expected to grow above 20% annually globally—the EU's probe may recalibrate investment strategies and operational models within this space. Should the Commission designate AWS and Azure as gatekeepers, the companies may face binding obligations that include enabling multi-cloud flexibility and avoiding preferential bundling, which could inflate compliance costs but also open market access for challengers.
From a risk perspective, potential regulatory constraints could create short-term uncertainties for Amazon and Microsoft stock performance, as evidenced by a slight market dip following the announcement. However, these adjustments may accelerate innovation cycles by fostering competitive pressure and encouraging decentralized cloud architectures.
In the medium term, the DMA's expansion to cloud services reflects the EU’s broader digital industrial strategy under the current geopolitical climate led by President Donald Trump’s US administration. The strategic importance of cloud sovereignty is compounded by rising AI applications demanding secure, accountable infrastructure – priorities shared across US and EU policy frameworks but subject to different regulatory philosophies.
For European enterprises relying heavily on AWS and Azure, the outcome of these investigations will be critical. Increased regulatory oversight could ensure fairer contractual conditions and enhanced service reliability but may also affect price structures. Stakeholders should monitor the Commission’s findings closely, as they will inform the evolution of the Digital Markets Act and consequently, the governance of cloud computing globally.
According to The Peninsula Qatar, the investigations are expected to be concluded within a year, after which the EU may impose new rules to ensure fairness and competitive practices in the cloud sector. The Digital Journal underscores the increasing pressure on the Commission from various industry actors to extend regulation to cloud services due to their essential role in the digital economy.
In conclusion, the EU’s investigations into Amazon and Microsoft’s cloud operations represent a significant regulatory milestone. They respond to the complex interplay of market dominance, technological innovation, political sovereignty concerns, and digital fairness. The outcomes will likely influence global cloud market dynamics, prompt reevaluation of digital market regulations, and shape the next generation of EU’s digital sovereignty initiatives.
