Artificial intelligence (AI) start-up Perplexity has made a surprise $34.5bn (£25.6bn) takeover offer for Google's Chrome internet browser. Moving Chrome to an independent operator committed to user safety would benefit the public, Perplexity said in a letter to Sundar Pichai, the boss of Google's owner Alphabet.

In an unlikely bid that shows the growing brashness of young artificial intelligence companies, the AI startup Perplexity has made an unsolicited offer to buy Google’s Chrome web browser for $34.5 billion.

Still, this offer for Chrome is far more than Perplexity has raised from investors and more than the startup’s current valuation. Perplexity has raised about $1.5 billion to date, Pitchbook estimates, including an extension round of $100 million raised last month that valued it at $18 billion, Bloomberg reported.
