July 3, 2026 — Alibaba’s shares have been driven to their lowest levels in the supplied data after Anthropic accused the Chinese company of mounting what it called the largest known “distillation attack” on its Claude AI model, turning an intellectual-property dispute into a fresh test of US-China technology tensions.
Alibaba Selloff Deepens After Anthropic AI Accusation
The allegation matters beyond the two companies because artificial intelligence models have become strategic assets, protected by capital spending, export controls and national-security scrutiny. Anthropic says Alibaba used about 25,000 fraudulent accounts to illicitly access and copy key features of Claude. Alibaba has responded by blocking employees from accessing Anthropic’s Claude Code, according to the supplied news context.

Alibaba’s US-listed shares closed at $96.14 on July 2, down about 26% from June 2 and roughly 45% below their January level of $175.57. The stock is trading far below its 50-day moving average of $122.07 and 200-day moving average of $145.82, while its 14-day RSI near 14 signals deeply oversold conditions by conventional technical measures.
The market reaction reflects a broader repricing of regulatory and geopolitical risk around Chinese technology companies. If US authorities pursue investigations or tighter restrictions, Alibaba could face pressure on overseas AI access, cloud partnerships and customer trust at a time when investors are already questioning the durability of China’s internet-sector recovery.
Sentiment has deteriorated sharply. Proprietary indicators from Adalytica.com put Alibaba earnings sentiment at 4, labeled “Extreme Fear,” down from 26 a day earlier and 37 on July 1, while awareness remained neutral. That suggests the dispute is becoming more visible to investors just as confidence in the stock is weakening.
The case also raises the stakes for Anthropic and its backers, including Amazon and Alphabet’s Google, whose cloud and AI businesses compete in the same market for enterprise adoption. Amazon closed at $242.67 on July 2, above its 200-day moving average, while Alphabet ended at $359.91, also above its 200-day average, leaving both better positioned than Alibaba in the current tape despite recent volatility.
The next catalyst is whether Anthropic’s claims lead to legal action, regulatory scrutiny or diplomatic pressure. For investors, the dispute is no longer just about one AI model; it is about whether Chinese technology champions can compete globally in AI without triggering a new round of restrictions.
