Reddit’s lawsuit, which was filed Wednesday, accuses the Amazon-backed AI company of breaching its user agreement. “As far back as December 2021…Anthropic was already—without authorization and in direct violation of Reddit’s User Agreement—training Claude on Reddit users” posts, the lawsuit claims.

Reddit started a legal fight against AI giant Anthropic over data scraping, highlighting issues of content ownership and copyright in the genAI era.

The social platform alleges that Anthropic used data from Reddit to train its AI. Anthropic denies the claims.
