Background and Relevance

Anthropic, a $61.5 billion AI company founded in 2021 by former OpenAI executives, is at the center of a growing legal battle between content providers and technology companies over the use of data to train increasingly sophisticated language models driving the AI generative revolution.

OpenAI, the creators of ChatGPT, spawned Anthropic, which has positioned itself as a firm focused on AI safety and responsible development. Known for its chatbot Claude, Anthropic aims to balance innovation with ethical considerations.

Reddit’s Allegations Against Anthropic

Reddit, the social media platform, filed a lawsuit in California state court against Anthropic, accusing it of illegally extracting millions of user comments to train its conversational AI, Claude, without permission or compensation.

The complaint highlights Anthropic’s dual nature: a public facade claiming ethical conduct and respect for boundaries, while privately disregarding any rules hindering its profit-seeking endeavors.

Despite Anthropic’s public statements about blocking bot access to Reddit, the company’s automated systems allegedly scraped content from Reddit’s servers over 100,000 times in the following months.

Reddit’s Demands

Reddit seeks monetary compensation and a court order to enforce Anthropic’s compliance with its user agreement terms.

Anthropic responded via email, stating, “We disagree with Reddit’s claims and will defend ourselves vigorously.”

Reddit’s Licensing Agreements with Other AI Companies

Reddit has previously entered licensing agreements with other AI giants, including Google and OpenAI. These deals allow those companies to use Reddit’s content under terms that protect user privacy and compensate the platform.

These agreements have contributed to Reddit’s stock price increase since its IPO in 2024. Reddit’s shares rose by over 6% on Wednesday following the lawsuit announcement.

Growing Trend of Lawsuits Against AI Companies

Musicians, book authors, visual artists, and news publications have filed lawsuits against various AI companies for using their data without permission or payment.

AI companies generally defend their practices by arguing legitimate use. They claim that training such technology with large datasets fundamentally alters the original content and is essential for innovation.

Though most of these lawsuits are still in their early stages, their outcomes could significantly shape the AI industry’s landscape.
