The European Commission has activated investigations into Amazon Web Services and Microsoft Azure under the Digital Markets Act. This step signals a vigilant stance from the Commission towards two of the largest players in cloud computing, despite AWS and Azure not fulfilling the specific quantitative requirements for automatic gatekeeper classification. The Commission aims to look beyond mere statistical thresholds, indicating concern about the overarching market behaviors that could hinder competition.
The Digital Markets Act, effective since 2022, is designed to preserve competitiveness within digital marketplaces. It empowers the Commission to tag certain major platforms as gatekeepers, imposing a variety of responsibilities including enhancing interoperability, ensuring data portability, and affording fair access to competitors. The focus of these inquiries is to scrutinize AWS's and Azure's influence in the cloud sector, particularly concerning potential anticompetitive conduct, customer lock-in scenarios, and obstacles that impede new competitors from emerging.
AWS and Azure currently dominate between 50 to 60 percent of the cloud infrastructure market across significant regions such as the European Union. Microsoft has expressed its readiness to assist with the investigation, while Amazon has yet to officially comment.
These investigations take place within a larger context of regulatory scrutiny, paralleling actions from the UK’s Competition and Markets Authority. The UK's authority is also evaluating the necessity of a “strategic market status” for AWS and Azure, reflecting a broader initiative to control tech giants' market power.
So, what are the implications for investors? Should the Commission classify AWS and Azure as gatekeepers, both companies will face substantial new obligations. They may be required to facilitate easier customer data transfers and workloads to rival platforms, rather than locking users into their ecosystems. The outcome directly affects the cloud market and introduces a level of uncertainty for investors, particularly with major revenue streams tied to their cloud services. The investigative timeline extends to approximately 12 months, meaning that the cloud business prospects of Amazon and Microsoft could remain uncertain into late 2026. The significance of these developments cannot be understated—Azure and AWS serve as critical profit drivers for their respective parent companies, thereby influencing overall financial performance.
