Hong Kong Share Sales Hit Five-Year High as Chinese AI Firms Lead

Hong Kong's equity capital markets just posted their busiest first half in five years, and the driver is one theme: AI. Bloomberg reports that IPOs, placements, and block trades combined raised almost $44 billion in the city during H1 2026, a 29% jump from a year earlier. Investor enthusiasm for AI-linked Chinese technology companies overpowered the drag of a sluggish broader equity market and regulatory headwinds, making Hong Kong the single largest contributor to the $122 billion raised across Asia-Pacific in the same period.

The deal list reads like a roll call of China's AI supply chain. Battery maker Contemporary Amperex Technology (CATL) completed a $5 billion share placement following its Hong Kong listing last year. Chip designer Biren Technology raised HK$5.58 billion in its debut, while frontier AI labs MiniMax and Knowledge Atlas, better known as Z.ai, and AI drug discovery company Insilico Medicine all made the market. More than 85% of Chinese AI-related companies that went public in 2026, 23 of 27, chose Hong Kong, according to Kharon. A Futunn financial report on the period noted that new listings delivered average first-day returns exceeding 60%, with AI-related stocks accounting for half of the ten best-performing IPOs year-to-date.

First-day pops above 60% usually say more about scarce float meeting concentrated anchor demand than about durable conviction, and that anchor demand is riding a specific AI infrastructure thesis that could compress quickly under stress. The Bloomberg tally also doesn't break the $44 billion down by deal type: a split between fresh IPOs, secondary placements, and block trades would show whether this is a broad reopening or a handful of landmark transactions doing most of the work. Skepticism is already in the air elsewhere, with two Chinese hedge funds warning that AI has become a "super bubble."

For Chinese AI and chip companies weighing a public raise, the signal from H1 2026 is that Hong Kong is open and receptive in a way it has not been for five years. The question heading into the second half is whether that window holds as US-China trade tensions remain elevated and the first wave of AI listings faces its earliest real test of post-IPO performance.
