Google just gave Chrome a brain

The browser just learned to think. Yesterday, Google turned Chrome into an autonomous AI agent. We wrote the full breakdown: Chrome Auto Browse, powered by Gemini 3, can now research flights, fill forms, manage subscriptions, and shop within your budget—all without you touching the keyboard. Paired with the Universal Commerce Protocol (co-developed with Shopify, Walmart, and Target), Google is consolidating the browser layer, the AI layer, and the commerce layer simultaneously. McKinsey pegs the agentic commerce market at $1 trillion in the US alone by 2030. Chrome’s 3.6 billion users make it the default on-ramp.

And the rest of Big Tech is writing even bigger checks. Nvidia, Microsoft, and Amazon are in talks to pour $60 billion into OpenAI, pushing its valuation toward $830 billion. Meanwhile, Meta just committed up to $135 billion in AI capex for 2026—nearly double last year—with Zuckerberg calling it the year of “personal superintelligence.” Combined Big Tech AI infrastructure spending is now projected at $470 billion this year. The capital war is no longer about training the best model. It’s about owning the interface where those models meet users.

While Big Tech fights over who controls the browser, AI is quietly changing what’s possible outside of it. DeepMind published AlphaGenome in Nature this week—the first AI that can decode 1 million DNA base pairs at single-letter resolution. Three thousand scientists across 160 countries are already using it to study cancer and neurodegenerative diseases. The $470 billion in AI infrastructure isn’t just building chatbots and shopping agents. It’s building the compute layer for breakthroughs that didn’t exist six months ago.
