OpenAI Unveils Atlas AI Web Browser

OpenAI has unveiled Atlas, a next‑generation web browser shown via livestream as the company pushes from a chat app toward a broader computing platform. Atlas is expected to embed ChatGPT and the Operator agent to perform tasks like booking reservations, autofill and direct in‑browser chat, and will likely be built on Chromium, though OpenAI has not confirmed immediate availability or a platform rollout. The announcement rattled markets, briefly sending Alphabet shares lower amid concerns about disruption to Google Chrome. The launch enters an increasingly crowded AI‑browser field — including Perplexity’s Comet, Chrome/Gemini, Microsoft Edge/Copilot and The Browser Company — and complements recent OpenAI platform moves such as ChatGPT Pulse, Sora, developer integrations and commerce partnerships. Key open questions remain about user adoption, whether OpenAI will charge for access, and whether Atlas can meaningfully dent Chrome’s dominant market share as bot traffic grows.
