Chinese artificial-intelligence developer MiniMax is raising HK$16 billion (approx. US$2.04 billion) through a share placement and convertible bonds to accelerate spending on AI infrastructure and large-model development, pressing ahead with its most capital-intensive phase even as its Hong Kong-listed stock slides and a lock-up expiry unleashes fresh selling. The move underscores how far MiniMax’s fortunes have diverged from those of rival Zhipu, the other big Chinese AI name to list in Hong Kong this year.
