Overview
On 25 June 2026, Alibaba Group Holding Ltd (NYSE:BABA) saw its share price decline by approximately 3% after reports surfaced that AI startup Anthropic accused the Chinese tech giant of illicitly scraping its Claude AI models.
Allegations Details
Anthropic sent a letter to U.S. senators and White House officials outlining a coordinated campaign, allegedly conducted by operators linked to Alibaba’s Qwen AI laboratory, that ran from April through June 2026. The campaign reportedly involved nearly 25,000 fraudulent accounts and resulted in about 28.8 million exchanges with Anthropic’s Claude model, aiming to bypass the startup’s restrictions that block access from China.
Nature of the Activity
Anthropic characterises the activity as “industrial‑scale” adversarial distillation, describing it as systematic harvesting of U.S. AI capabilities across frontier labs and repackaging them without incurring the original training and R&D costs. The startup warns that models cloned through this method often lack critical safety guardrails.
Policy and Compliance Concerns
Because Anthropic explicitly blocks its products from being accessed in China, the alleged operation constitutes a breach of its distribution and terms‑of‑service policies. Anthropic has urged the U.S. administration to implement stricter guardrails to halt such systematic data harvesting by Chinese AI labs.
Market Reaction
Following the disclosure, Alibaba’s stock fell roughly 3% on the day, reflecting investor concerns over potential regulatory scrutiny and reputational damage.
