AI search engine Perplexity has made an unsolicited $34.5 billion cash offer to acquire Google’s Chrome browser. Perplexity said its proposal includes keeping Chrome’s underlying Chromium engine open-source and investing $3 billion in the project.

The company also pledged not to change user defaults, including leaving Google as the browser’s default search engine rather than replacing it with Perplexity’s AI-powered search.

The bid comes as Google faces a U.S. Department of Justice proposal, made in March, to force the company to sell Chrome following a court ruling that it had illegally maintained a monopoly in online search. Google has vowed to fight the decision. A ruling on remedies could come later this month, according to a Perplexity spokesperson.

If Chrome is put up for sale, it is expected to attract significant interest. The browser holds about 68% of the global market, according to Statcounter. When the DOJ first floated the idea of a divestiture, both Perplexity and OpenAI expressed interest in buying the browser.

DuckDuckGo’s CEO testified in April that Chrome could be worth more than $50 billion, suggesting Perplexity’s bid could represent a discount. The offer also far exceeds Perplexity’s own valuation and funding to date; PitchBook estimates the startup has raised $1.5 billion, including a $100 million extension round last month that valued it at $18 billion.

Perplexity recently launched its own browser, Comet, and last month reportedly submitted a bid to merge with TikTok.
