A federal judge in the Southern District of New York denied Perplexity's motion to dismiss Reddit's lawsuit over data scraping, Reuters reported on 31 July 2026. The ruling, by Judge Paul Engelmayer, allowed Reddit to keep pressing claims that Perplexity and three data scrapers unlawfully circumvented protections to take Reddit content for AI training. The decision let the case proceed. It was not a finding that Perplexity was liable, and no damages were set.

Reuters headlined its report as Perplexity AI losing its bid to toss the Reddit lawsuit over data scraping. A Reuters update dated 3 August 2026 quoted a statement from Oxylabs, one of the scraping companies Reddit sued. Oxylabs said the Friday ruling addressed only arguments made by Perplexity and SerpApi. It said its own motion to dismiss Reddit's case against it was still pending, so the ruling did not decide the claims against every company named in the suit.
