Z.ai, the Hong Kong-listed developer behind the GLM family of AI models, said this week it has completed a combined financing round worth roughly $5 billion, split between a $2 billion share placement and $3 billion in zero-coupon convertible bonds — its second multibillion-dollar raise in two months.
The company priced 21.97 million new shares at HK$714 each, a roughly 10% discount to their HK$793 closing price on September 11, generating about HK$15.7 billion (roughly $2 billion). Alongside that, Z.ai issued 20.14 billion yuan (roughly $3 billion) in zero-coupon convertible bonds due September 2027, with an initial conversion price of HK$892.50 a share, according to TechNode and Caixin Global.
Roughly 60% of the proceeds are earmarked for research, computing infrastructure and talent tied to next-generation GLM foundation models, including work on a fully self-training system, large-scale training and inference, automated training-data generation, and adaptation to domestic Chinese chips. Another 15% is set aside for expansion and possible acquisitions, with the remainder going toward capital-structure optimization.
Second Raise in Ten Weeks
The round follows a roughly $4 billion share sale in July and a January initial public offering that raised HK$4.9 billion — funds Caixin's reporting says Z.ai has already largely spent. Shares fell more than 10% after the new financing was announced, a reaction some analysts attributed to dilution concerns even as the company signaled no shortage of investor appetite for its stock.
The back-to-back raises underscore how aggressively Chinese AI developers are moving to match the capital intensity of their U.S. counterparts. Z.ai and its rivals are racing to iterate on foundation models and expand computing capacity even as export controls complicate access to the most advanced chips, pushing several firms toward domestic silicon and homegrown training infrastructure.
Z.ai has not disclosed a fresh valuation tied to the latest raise. The company's rapid fundraising cadence — three distinct capital raises within roughly eight months of its stock-market debut — places it among the most aggressively financed AI labs in China, alongside peers such as Moonshot AI, which has separately pursued a confidential Hong Kong listing of its own.
