Reddit’s AI Data Scraping Suit Against Anthropic Advances in Court
Court rules Reddit’s lawsuit against Anthropic over unauthorized scraping can proceed.
Why it matters: The ruling highlights critical legal conflicts over AI training data rights and platform terms of service enforcement, essential for legal and IP counsel in tech.
- Reddit sued Anthropic on June 4, 2025, alleging unauthorized scraping of Reddit content to train AI model Claude.
- Anthropic’s bots accessed or attempted access to Reddit more than 100,000 times after July 2024 despite public claims of blocking scraping.
- Unlike OpenAI and Google, Anthropic did not license Reddit’s data before using it for AI training.
- On September 19, 2026, a federal court rejected Anthropic's motion to dismiss, allowing Reddit's lawsuit to move forward.
On June 4, 2025, Reddit filed a lawsuit in California Superior Court accusing Anthropic of using automated bots to scrape Reddit's content without permission. The scraped data was allegedly used to train Anthropic's AI model, Claude, violating Reddit’s terms of service and user privacy.
Reddit's claims include breach of contract, unjust enrichment, trespass to chattels, tortious interference with contract, and unfair competition under California law. Notably, Anthropic had publicly stated in July 2024 that it blocked its bots from crawling Reddit, yet Reddit alleges more than 100,000 access attempts occurred afterward, indicating continued scraping activity.
In contrast, other major AI developers like OpenAI and Google have entered into licensing agreements with Reddit to legally access and use its data, a step Anthropic did not take. Reddit’s Chief Legal Officer Ben Lee said, "We will not tolerate profit-seeking entities like Anthropic commercially exploiting Reddit content for billions of dollars without any return for redditors or respect for their privacy."
Anthropic has denied the allegations. "We disagree with Reddit's claims and will defend ourselves vigorously," said spokesperson Danielle Ghighlieri.
On September 19, 2026, a federal District Court judge largely rejected Anthropic’s motion to dismiss the case, allowing Reddit’s lawsuit to proceed. This decision underscores the enforceability of platform terms of service in protecting user-generated content from unauthorized use, a critical point in the evolving legal landscape around AI training data.
The case shines a spotlight on growing legal battles at the intersection of AI development practices and data ownership rights, with significant implications for legal professionals advising AI developers, platforms, and users.
By the numbers:
- 100,000+ — alleged Anthropic bot access attempts on Reddit after July 2024
- June 4, 2025 — date Reddit filed the lawsuit
- September 19, 2026 — court ruling allowing lawsuit to proceed
