AI startup Perplexity's valuation rose to $20 billion in fresh funding talks. It's a $2 billion jump from its last fundraise in July.

The unsolicited bid was sent to Alphabet’s Google ahead of a US court decision that could force the giant search group to sell the browser.

Perplexity AI made a $34.5 billion unsolicited all-cash offer for Alphabet's Chrome browser on Tuesday, a bid far above its own valuation as the startup reaches for the browser's billions of users pivotal to the AI search race.
