Shares jumped as much as 22% after the Chinese AI company outlined a discounted US$4 billion follow-on fundraising, months after its January 2026 Hong Kong debut and ahead of its July 8 insider lock-up expiry.
Zhipu AI is seeking to raise about US$4 billion through a secondary share sale in Hong Kong, a follow-on offering that would far exceed the roughly US$560 million, or about HK$4.35 billion, it raised in its January 8, 2026 initial public offering. The Tsinghua University spinoff, which develops the GLM family of large language models and counts Alibaba and Tencent among its backers, has seen its shares rise between 1,500% and 2,000% since listing. After the fundraising plan was unveiled, Zhipu AI shares climbed as much as 22% in early Thursday trading before paring gains to trade 9% higher at HK$1,989.00, or US$253.72, outperforming a 0.1% decline in the Hang Seng Tech Index. The company priced the new shares at a discount, but investors appeared to focus on the scale of the capital raise and its growth implications. The timing also coincides with the July 8 expiry of the six-month post-IPO lock-up for insiders, which could allow the company to channel potential selling pressure into a structured capital raise. Zhipu has been gaining traction in enterprise applications, and the recent launch of GLM-5.2 reportedly strengthened its position. It is also reportedly considering additional listings in Shanghai, which could broaden access to mainland Chinese capital. For investors, the main question remains whether growth funded by the new capital will outweigh dilution from a larger share count.
