Market Chatter: Microsoft, Amazon Units to Reportedly Face Additional EU Antitrust Oversight

08:18 AM EDT, 10/02/2026 (MT Newswires) -- Microsoft's (MSF.F) Azure and Amazon's (AMZ.F) Amazon Web Services could come under additional scrutiny as regulators probe whether the tech giants' arms fall under the European Union's Big Tech rules. Bloomberg News reported Friday, citing unnamed sources, that the probe under the Digital Markets Act is in its final stages, with a decision expected in November. If the European Commission concludes that the companies fall under the designation, it will give them half a year to comply with the rules, including requirements aimed at ensuring interoperability and limiting customer lock-in and self-preferencing, the report said. European Commission, Microsoft, and Amazon did not immediately respond to requests for comment from MT Newswires.
