Artificial intelligence start-up Perplexity AI has made a surprise $34.5bn (£25.6bn) takeover bid for the world's most popular web browser, Google Chrome. The three-year-old firm, whose backers include Amazon founder Jeff Bezos and chip maker Nvidia, is headed by a former Google and OpenAI employee.

Many see Perplexity’s bid to buy Google’s Chrome browser as a strategic statement rather than a likely transaction.

AI startup Perplexity said it made a formal offer to acquire Google’s Chrome browser for $34.5 billion, in anticipation of requirements that may be imposed on the search giant in antitrust proceedings.
