Tech billionaire Elon Musk has publicly condemned the artificial intelligence firm Anthropic, accusing the company of massive data theft and hypocrisy.
This confrontation follows Anthropic’s recent claims that competing Chinese artificial intelligence models unlawfully extracted training data from its flagship Claude model.
The Distillation Controversy
Earlier this week, Anthropic published a report accusing Chinese AI developers, including DeepSeek, Moonshot AI, and MiniMax, of conducting industrial-scale distillation attacks.
The San Francisco-based lab alleged that these competitors created over 24,000 fraudulent accounts and generated more than 16 million interactions to copy Claude’s advanced capabilities.
Distillation is a technique where smaller models are trained directly on the outputs of more powerful systems.
Anthropic warned that this large-scale data extraction could enable foreign adversaries to quickly replicate advanced systems, raising significant national security and cybercrime concerns.
Following Anthropic’s complaints, the CEO of xAI quickly pointed out the company’s own legal history regarding data acquisition.
| Entity Involved | Role in Controversy | Allegations or Financial Impact |
|---|---|---|
| Anthropic | Accuser and Accused | Settled a $1.5 billion copyright lawsuit and faces a $3 billion publisher lawsuit . |
| DeepSeek & MiniMax | Accused by Anthropic | Allegedly used 24,000 fake accounts for industrial-scale distillation . |
| Elon Musk | Critic | Accused Anthropic of massive training data theft and severe hypocrisy . |
Taking to his social media platform, Musk stated, “Anthropic is guilty of stealing training data at massive scale and has had to pay multi-billion dollar settlements for their theft. This is just a fact”.
His remarks highlight recent copyright disputes involving the Amazon-backed startup. In September 2025, Anthropic agreed to a $1.5 billion settlement in a class-action lawsuit filed by authors who claimed their pirated books were used to train Claude.
Furthermore, the company is currently facing another major lawsuit from music publishers seeking $3 billion in damages over similar piracy and copyright infringement claims.
