Artificial intelligence search company Perplexity has made an unsolicited, $34.5 billion offer to purchase Google’s Chrome browser, a surprise move by a Google Search challenger that’s looking to upend how people find information online.

According to a new report, Perplexity AI is set for another fundraise, this time at a $20 billion valuation, a move that comes on the heels of its bid to buy Google Chrome.

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.
