TLDR: OpenAI and Perplexity are directly targeting Google Chrome’s commanding lead in the web browser and search market with the introduction of their new AI-powered browsers. Perplexity has launched ‘Comet,’ an agentic AI browser capable of performing complex tasks, while OpenAI is reportedly nearing the release of its ChatGPT-integrated browser. This move signals a new era in the ‘browser wars,’ aiming to capture a share of the lucrative $300 billion search industry by redefining user interaction and data control.
The landscape of web browsing and search is undergoing a significant transformation as artificial intelligence powerhouses OpenAI and Perplexity make aggressive moves to challenge Google Chrome’s long-standing market dominance. Both companies have unveiled plans for AI-powered web browsers, signaling a new front in the ‘browser wars’ with implications for the estimated $300 billion search goldmine.
Perplexity, a San Francisco-based startup valued at $14 billion and backed by prominent investors including Nvidia, Jeff Bezos, and SoftBank, officially launched its AI-powered web browser, ‘Comet,’ on July 9, 2025. Initially available to subscribers of its $200 per month Max plan and a select group of investors, Comet is designed to revolutionize the browsing experience. Unlike traditional browsers, Comet integrates an AI chatbot to replace conventional search queries and features an ‘AI agent’ called Comet Assistant. This assistant is capable of performing a wide array of tasks, from booking meetings and sending emails to making purchases, providing daily briefings, comparing products, and summarizing content, effectively acting on behalf of the user. Perplexity emphasizes user privacy, stating that Comet stores data locally and avoids using personal information for model training. However, the company has faced criticism from media organizations like News Corp, Forbes, Wired, and The Wall Street Journal for its alleged use of content without consent or compensation.
Meanwhile, Reuters reported on July 9, 2025, that OpenAI, the creator of the widely popular ChatGPT, is also nearing the launch of its own AI-powered web browser. This forthcoming browser is expected to be deeply integrated with ChatGPT, leveraging its existing user base of over 500 million weekly active users. OpenAI’s browser aims to streamline online activities, enabling users to perform real-time tasks such as shopping, making reservations, submitting forms, and receiving personalized assistance without the need for manual navigation.
These strategic entries directly target Google Chrome, which, as of June 2025, commands a formidable 68% to 68.35% of the global browser market share. Historically, browser dominance has been crucial for controlling data collection, advertising revenue, and user loyalty within tech ecosystems. Experts suggest that Google’s comparatively slower adoption of advanced AI technologies within its browser has created a significant opening for these agile startups.
Steve Jang, founder and managing partner at Kindred Ventures and an early investor in Perplexity, commented on the dynamic, stating that ‘every tech cycle brings new startups that challenge legacy platforms, and they often succeed in gaining significant market share.’ The underlying motivation for these AI companies is clear: ‘Owning the browser itself is one way of securing the place of your search product, and all the benefits that go with that (including to your ads business),’ explained Niamh Burns, a senior research analyst at Enders Analysis. She added, ‘And the data advantages are huge when you have that kind of access to a user’s journey.’ For AI platforms, building a browser is not just about enhancing user experience but also about gaining access to a rich stream of ‘data exhaust’—every scroll, click, and query—which serves as raw material for training their sophisticated AI models.

Jesse Dwyer, Perplexity’s head of communications, articulated the competitive stance, telling Digiday, ‘If users lose this browser war, it will be from a familiar playbook – a monopolistic ‘everything company’ forcing their model on everyone. In this sense, OpenAI’s offering will not differ from Chrome’s.’ The timing of these launches is particularly opportune, as Google faces potential remedies from its ongoing antitrust case, which could even include a spin-off of the Chrome browser, potentially creating further opportunities for new entrants. Despite the formidable challenge, Google Chrome maintains a significant advantage with over 3 billion users and a vast repository of user data, making the process of switching browsers a considerable hurdle for new competitors.
