Browser Wars Have Begun: OpenAI's 'Atlas' Launch Sparks Anxiety For Alphabet
Shares of Google fell after OpenAI unveiled plans to launch its first AI-powered web browser, signaling direct competition with Google Chrome.
The new browser, called “Atlas,” will debut globally on macOS, with Windows, iOS, and Android versions coming in the near term. According to Sam Altman and other OpenAI executives, Atlas will feature:
-
An AI agent capable of fully controlling your browser
-
The ability to chat directly with any website you visit
-
Conversational access to your entire browsing history
-
Deeply integrated, personalized AI features are woven into every aspect of the browsing experience
This might mark the R.I.P. moment for Perplexity’s Comet, and perhaps even for Chrome.
Or maybe it’s simply the point in history when the AI browser war officially began.

Think about it: ChatGPT already has 700 million weekly active users worldwide, while Chrome boasts 3.45 billion users globally and controls about 64.9% of the browser market as of March 2025. OpenAI wants to take a serious bite out of that market share.
