Reddit forecast third-quarter revenue above Wall Street estimates on Thursday, betting on growing digital advertising driven by its artificial intelligence-powered marketing tools and sending its shares up 9% in extended trading. The forecast follows bigger rival Meta’s upbeat second-quarter results and strong revenue outlook on Wednesday, lifted by the Facebook and Instagram parent’s core ad business. Advertisers are increasingly turning to platforms such as Reddit, Meta, and TikTok, which offer advanced AI-powered tools for automated ad creation, precise audience targeting and access to fast-growing user bases.
