Zhipu (Z.ai) Shares Jump 37% After Launch of Data Center Built on Chinese Chips

Shares of Chinese AI developer Z.ai (Zhipu) jumped 37% on the Hong Kong stock exchange on July 21, 2026, closing at HK$1219 ($155), after the company finished building a 1-gigawatt data center that runs entirely on Chinese chips.

What triggered the surge

Z.ai shares rose 37% in a single trading session on July 21, 2026, recovering a weekly drop of more than 40%. According to the South China Morning Post, the reversal was sparked by news that the giant AI computing center had been completed.

• Share price: +37% on the day, closing at HK$1219 ($155)
• Before that: a drop of more than 40% over the week
• Capacity of the new data center: 1 gigawatt (GW)
• Hardware: entirely Chinese chips, no Nvidia accelerators
• Purpose: training and deploying models in the GLM family

What is this data center?

Z.ai's data center is a 1-gigawatt computing complex designed to train and run the company's own GLM models. According to sources familiar with the matter, the facility has already been built and is being brought into operation.

At 1 GW, the site sits alongside the world's largest AI clusters; American hyperscalers budget the same amount of power for their flagship campuses. For training large language models, the key resource is the sheer volume of compute, so a facility of this scale lets Z.ai train larger versions of GLM without renting capacity from others.

Why Chinese chips matter

The central detail of the news is that the data center runs entirely on Chinese chips, with no Nvidia processors. It is a direct response to US export restrictions, which since 2022 have cut China off from top-tier American-made AI accelerators.

The company has built a 1 GW computing center that will be used to train and deploy GLM models, according to sources familiar with the matter, the

South China Morning Post reports.

By betting on domestic hardware, Zhipu, best known for its GLM family of models, reduces its dependence on imported accelerators and on political risk. For investors, it is a signal that Chinese AI companies can scale up compute on their own, and that is exactly what showed up in the share price the same day.

What this means

The 37% reversal in Z.ai shares shows that the market places a high value on sovereign AI infrastructure: a company-owned data center built on Chinese chips is seen as a strategic advantage, not a forced substitute for Nvidia. For China's AI industry as a whole, it is another step toward independence from Western hardware.
