TECH: EU's Antitrust Chief to Meet Pichai, Zuckerberg, Altman and Jassy in San Francisco This Week

Brussels is taking its AI competition agenda straight to Silicon Valley. Reuters reports EU Competition Commissioner Teresa Ribera is in San Francisco for first-time meetings today with Google CEO Sundar Pichai, Meta CEO Mark Zuckerberg and OpenAI CEO Sam Altman. Amazon CEO Andy Jassy is scheduled to meet her tomorrow. Ribera said earlier this month she is reviewing the "entire AI stack", spanning chatbots, training data and cloud infrastructure. The trip follows existing probes into Google and Meta's business practices, and comes as EU regulators assess whether AWS and Microsoft Azure should be designated as gatekeepers under the Digital Markets Act. EU officials are focused on whether dominant firms are steering users toward their own AI services on their own platforms, potentially squeezing out rivals. With cloud, data, models and distribution increasingly concentrated, regulators are treating vertical integration as a possible route to market capture. The push arrives as the EU also reopens parts of its AI Act via an omnibus proposal that critics argue could water down safeguards, adding to an already complex regulatory landscape. Four CEOs, one regulator, one week: Europe's AI antitrust phase is underway.
