Alibaba to Ban Claude Code in Workplace Over Alleged Backdoor Security Risks, Report Says

Alibaba will ban employees from using Anthropic’s Claude Code starting July 10, 2026. Reuters reported the move Thursday, citing a source familiar with the decision. The ban stems from alleged security risks involving embedded backdoors in the coding tool. Chinese financial outlet Yicai first reported the story earlier this week. Alibaba shares fell 0.7% on the news, underperforming Hong Kong’s broader Hang Seng index. The decision follows weeks of rising tension between Alibaba and Anthropic over AI model access.

Alibaba Flags Claude Code as High-Risk Software

Alibaba added Claude Code to its internal high-risk software list this week. The company reportedly told employees to uninstall it by July 10. All Anthropic tools, including Claude, Sonnet, and Opus, now face the same restriction. Developers say the concern traces back to Claude Code version 2.1.91, released in April 2026.

• The version allegedly checks device time zones for Asia/Shanghai or Asia/Urumqi settings.
• It reportedly scans proxy addresses for terms linked to Chinese AI firms.
• Named companies include Alibaba, ByteDance, Baidu, Moonshot AI, and MiniMax.

Alibaba has recommended its own Qoder tool as a direct replacement for banned employees.

Anthropic and Alibaba Tensions Escalate Through June

This Alibaba decision follows a rocky month between the two AI companies. Anthropic accused operators tied to Alibaba’s Qwen unit of large-scale model extraction on June 24, 2026. BABA shares hit a 16-month low the following day after that accusation surfaced. Alibaba has not publicly addressed Anthropic’s claims about fraudulent account activity. Separately, Alibaba sued the U.S. Defense Department on June 23 over a military denylist listing. Daiwa cut its Alibaba price target to $175 from $200 shortly after these disputes emerged.

How Financial Firms Are Also Restricting Claude

Alibaba isn’t the only major institution limiting Claude access this year. JPMorgan reportedly stopped Hong Kong employees from selecting Claude models on its approved tool list in June. That decision cited Anthropic’s licensing terms restricting use across Greater China. Goldman Sachs introduced a similar restriction earlier, based on the same regional licensing language. Anthropic told the Financial Times that Claude was never officially supported in Hong Kong. These moves reflect growing friction over cross-border AI deployment among global institutions.

Alibaba Stock Performance Today

Alibaba’s ADR (NYSE: BABA) traded near $96.14 on July 3, 2026, down from a $97.99 previous close. The stock’s day range spanned $95.19 to $97.95, well below its 52-week high of $192.67. That high was set before this year’s regulatory and AI-related pressures mounted. Analysts remain broadly bullish despite the pullback, with 38 of 39 covering firms rating BABA a buy.

• 52-week range: $91.99 to $192.67.
• Average 12-month price target: roughly $191.59, implying significant upside.
• Goldman Sachs removed Alibaba from its APAC Conviction List on July 1.

The stock also carries fresh legal costs after a $600 million DOJ settlement announced July 1.

What This Means for AI and China Tech Stocks

Alibaba’s Claude Code ban adds to broader scrutiny facing U.S. AI tools operating in China. Competing Chinese tech firms like Tencent Holdings, Baidu, and Xiaomi are watching closely. Many have launched their own share buyback programs this year to steady investor confidence. Alibaba continues investing in its Qwen AI family, including the February 2026 release of Qwen 3.5. That model showed competitive performance against global systems while lowering operating costs for enterprise users. The dispute could accelerate adoption of homegrown alternatives like Qoder across Chinese workplaces.

Final Thoughts

Alibaba’s decision to ban Claude Code marks a notable escalation in U.S.-China AI tensions this month. The alleged backdoor concerns, combined with Anthropic’s own model-theft accusations, point to deepening distrust between the firms. BABA shares remain well below their 52-week high, though Wall Street analysts still see substantial upside. Investors should watch how this dispute affects Alibaba’s Qwen ecosystem and its push into enterprise AI tools. The coming weeks may reveal whether other Chinese firms follow Alibaba’s lead on Claude Code restrictions.
