EU Intensifies Regulatory Scrutiny on Big Tech with Cloud Gatekeeper Decisions and AI Office Rulebook

The European Commission is advancing a three-pronged regulatory strategy targeting U.S. tech giants, effective November 1, 2026. This includes weighing a decision to designate Amazon Web Services (AWS) and Microsoft Azure as 'cloud gatekeepers' under the Digital Markets Act (DMA), opening a draft AI Office rulebook for feedback, and concluding a DMA review that largely maintained the existing law. These actions signify a significant push to regulate market concentration and practices in the cloud computing and artificial intelligence sectors.
