U.S. weighs new curbs on remote AI chip access, sending Alibaba and Tencent shares sharply lower

Reports on 12 November 2026 said the U.S. Commerce Department is preparing rules that would block Chinese AI firms from remotely accessing advanced chips in overseas data centres, targeting a loophole used by companies such as Alibaba and Tencent. The news triggered a sell‑off, with Alibaba’s Hong Kong shares falling around 6‑7% and Tencent’s down about 2½% that day. The proposed measures would extend export controls to Malaysia, Singapore and Thailand.

The anticipated restrictions could raise Chinese AI developers’ costs and slow model training, pressuring earnings and cash flow for Alibaba and Tencent. Investors should expect heightened regulatory risk and possible revenue impact from limited chip access.
