Investors have upvoted Reddit in droves.

Reddit stock is slated to start trading on the New York Stock Exchange Thursday after the IPO priced at $34 a share — at the top of its expected initial price range — as investors showed enthusiasm for a social media company that has ambitious expansion plans but has never been profitable.

Valued at around $6.4 billion, Reddit is trading under the ticker symbol RDDT. The IPO is being viewed as a test of investor appetite for a social media company in an era where artificial intelligence is all the rage in the technology industry.
