Atlas Browser: Will OpenAI Change the Browsing World and Threaten Chrome's Threat?

On October 21, 2025, OpenAI launched the ChatGPT Atlas Browser, an ambitious move aimed at redefining browsing with artificial intelligence.

The browser combines the Chromium engine and fully integrates with ChatGPT, transforming the internet into a smart, interactive experience. In the following article, we explore the new browser's details, features, future prospects, competition, and anticipated challenges.

ChatGPT Atlas release date On October 21, 2025, OpenAI unveiled the new browser during a livestream led by CEO Sam Altman, as part of a strategy to diversify revenue sources after significant financial losses of approximately $5 billion by 2024.

The browser is currently available on Mac globally, with plans to support iOS, Windows, and Android in the coming weeks. The project is led by Ben Goodger, who joined the company from Google in June 2024, further strengthening the browser's technical credibility.

Atlas Browser is available for free to all ChatGPT users, starting with the free plans, with advanced features like Agent Mode available exclusively on paid plans. It's based on the open-source Chromium engine, ensuring compatibility with Chrome extensions and high performance, with seamless integration with OpenAI tools like DALL-E for image generation and Whisper for voice translation.

The launch of ChatGPT Atlas comes amid intense browser competition, with Google integrating the Gemini model into Chrome, Microsoft developing Copilot features in Edge, and Proplexity launching the Comet browser.

Atlas is based on the ChatGPT model, which serves approximately 250 million weekly active users in 2024, with growth forecasts in 2025.

Sam described Atlas as "a once-in-a-decade opportunity to rethink the browser."

What impact will the announcement of Atlas Browser have on the browser market? The Atlas announcement sent markets into a tailspin, with shares of Alphabet, Google's parent company, falling as much as 4.8% to $246.15 on Tuesday, October 21, 2025, before settling down 2.4% at $250.46, wiping out about $100 billion in market value.

This reflects investor concern that Atlas could threaten Google's core search and advertising businesses. Chrome dominates 71.9% of the global browser market, and Google controls 90% of the search advertising market, generating $71.34 billion in advertising revenue in the second quarter of 2025, according to StatCounter.

According to DA Davidson analyst Gil Luria, Atlas' chat integration could be a prelude to ad sales, which could take a significant share of Google's search advertising.

Scotiabank analysts also noted that Atlas could shift high-intent search queries, such as shopping or comparisons, away from the most popular search engine, though they expect a limited impact in the short term due to Chrome's dominance and extensive integration with websites.

What challenges does Atlas Browser face? Atlas faces major privacy challenges, as broad access to browsing data raises regulatory concerns such as GDPR, with reports indicating that 40% of users fear sharing sensitive information without adequate safeguards.

It also relies on a stable internet connection, which limits its use in areas with weak internet connections, such as some Middle Eastern countries, where delays reduced the effectiveness of proxy features by 30% in initial tests.

In addition to fierce competition with other browsers and lawsuits over model training, which could cost OpenAI billions and erode confidence, the browser is expected to capture only 5-10% of the market in its first year.

It's powered by features like agent mode and personal memory, making it ideal for Middle Eastern marketing and education professionals, with Arabic support and expectations of attracting between 50 and 100 million users.
