Reddit Lawsuit Against Anthropic AI Has Stakes for Sports
In a new lawsuit, Reddit accuses AI company Anthropic of illegally scraping its users' data—including posts authored by sports fans who use the popular online discussion platform.
Reddit's complaint, drafted by John B. Quinn and other attorneys from Quinn Emanuel Urquhart & Sullivan, was filed on Wednesday in a California court. It contends Anthropic breached the Reddit user agreement by scraping Reddit content through its web crawler, ClaudeBot. The web crawler provides training data for Anthropic's AI tool, Claude, which relies on large language models (LLMs) that distill data and language.

Other claims in the complaint include tortious interference and unjust enrichment. Scraping Reddit content is portrayed as undermining Reddit's obligations to its more than 100 million daily active unique users, including to protect their privacy. Reddit also contends Anthropic subverts its assurances to users that they control their expressions, including when deleting posts from public view.
Scraping is key to AI. Automated technology makes requests to a website, then copies the results and tries to make sense of them. Anthropic, Reddit claims, finds Reddit data 'to be of the highest quality and well-suited for fine-tuning AI models' and useful for training AI. Anthropic allegedly violates users' privacy, since those users 'have no way of knowing' their data has been taken.
Reddit, valued at $6.4 billion in its initial public offering last year, has hundreds of thousands of 'subreddits,' or online communities that cover numerous shared interests. Many subreddits are sports related, including r/sports, which has 22 million fans, r/nba (17 million) and the college football-centered r/CFB (4.4 million). Some pro franchises, including the Miami Dolphins (r/miamidolphins) and Dallas Cowboys (r/cowboys), have official subreddits.
Reddit contends its unique features elevate its content and thus make the content more attractive to scraping endeavors. Reddit users submit posts, which can include original commentary, links, polls and videos, and they upvote or downvote content. This voting influences whether a post appears on the subreddit's front page or is more obscurely placed. Subreddit communities also self-police, with prohibitions on personal attacks, harassment, racism and spam. These practices can generate thoughtful and detailed commentary.
Reddit estimates that ClaudeBot's scraping of Reddit has 'catapulted Anthropic into its valuation of tens of billions of dollars.' Meanwhile, Reddit says the company and its users lose out, because they 'realize no benefits from the technology that they helped create.'
Anthropic allegedly trained ClaudeBot to extract data from Reddit starting in December 2021. Anthropic CEO Dario Amodei is quoted in the complaint as praising Reddit content, especially content found in prominent subreddits. Although Anthropic indicated it had stopped scraping Reddit in July 2024, Reddit says audit logs show Anthropic 'continued to deploy its automated bots to access Reddit content' more than 100,000 times in subsequent months.
Reddit also unfavorably compares Anthropic to OpenAI and Google, which are 'giants in the AI space.' Reddit says OpenAI and Google 'entered into formal partnerships with Reddit' that permitted them to use Reddit content but only in ways that 'protect Reddit and its users' interests and privacy.' In contrast, Anthropic is depicted as engaging in unauthorized activities.
In a statement shared with media, an Anthropic spokesperson said, 'we disagree with Reddit's claims, and we will defend ourselves vigorously.' In the weeks ahead, attorneys or Anthropic will answer Reddit's complaint and argue the company has not broken any laws.
Reddit v. Anthropic has implications beyond the posts of Reddit users. Web crawlers scraping is a constant activity on the Internet, including message boards, blogs and other forums where sports fans and followers express viewpoints. The use of this content to train AI without knowledge or explicit consent by users is a legal topic sure to stir debate in the years ahead.
