Perplexity has raised hundreds of millions from Jeff Bezos and Nvidia while clashing with top media organizations over alleged copyright violations.

AI search engine Perplexity is in fundraising talks and hopes to raise around $500 million at an $8 billion valuation, according to the Wall Street Journal. If a deal happens with those terms, it would more than double Perplexity's valuation from its $3 billion valuation when it raised from SoftBank over the summer.

AI search startup Perplexity is engaging in its fourth funding round this year, targeting a valuation of up to $8 billion.
