Anthropic Accuses Alibaba of Large-Scale AI Model Theft
Anthropic has accused Chinese tech giant Alibaba of orchestrating the largest known 'distillation attack' on its Claude AI models. In a letter dated June 10, 2026, sent to US senators and the White House, Anthropic claims operators linked to Alibaba's Qwen lab used roughly 25,000 fraudulent accounts to conduct about 28.8 million interactions with Claude between April 22 and June 5, 2026, targeting software engineering and agentic reasoning capabilities. The allegations, which became public on June 24, are unsubstantiated and Alibaba has not commented. Anthropic is urging the US government to tighten antitrust guidance, impose penalties for systematic distillation, and support export controls. Alibaba's stock fell about 3 percent. In February 2026, Anthropic made similar accusations against DeepSeek, Moonshot AI, and MiniMax. The case highlights how frontier AI models can become training-data sources.
Allegation of the largest known AI model distillation attack involving Alibaba could drive new US export controls and reshape AI model access, with broader consequences for AI-dependent technologies and the AdTech ecosystem.
