AI start-up Perplexity has raised US$500 million through a new funding round that values the OpenAI rival at around US$9 billion, according to reports.
VC investing giant Institutional Venture Partners led the funding round, which comes after a raft of new competing AI-based search engine launches in recent weeks.
OpenAI recently launched ChatGPT Search, its rival to Perplexity while Google reportedly is looking to incorporate some of the start-up’s capabilities such as adding a chatbot-like "AI mode" into its search engine.

Like its rivals, Perplexity has had its share of controversy including accusations of plagiarism from news organisations, many of which it has now entered revenue-sharing deals, and a class action for copyright infringement.
Claiming to have at least 15 million users earlier in the year, Perplexity has kept ahead of its rivals using innovations such as a finance product that monitors share prices and earnings data using real-time information.
Reflecting its growth, Perplexity’s value has rocketed this year compared to earlier funding rounds.
Valued at US$ 1 billion in April, this rose to US$3 billion in June when Softbank came on board as an investor and now has reached US$9 billion.
As well as Softbank, Perplexity boasts tech darling Nvidia and Amazon founder Jeff Bezos among its investors.
Like OpenAI’s ChatGPT, Perplexity offers free-to-access and paid-for products.
