Zhipu AI and MiniMax join Hang Seng Tech Index for AI boost

Chinese AI firms MiniMax and Knowledge Atlas Technology, better known as Zhipu AI, will be added to the Hang Seng Tech Index next month, addressing investor criticism that Hong Kong's primary technology gauge has underperformed by missing the global artificial intelligence boom. The additions are part of a broader rebalancing by Hang Seng Indexes Co., which will also see Shanghai-based courier J&T Global Express, lightweight metal giant Aluminum Corp of China, and Beijing-founded global drug firm BeOne Medicines join the benchmark Hang Seng Index. These changes take effect after the market close on June 5, increasing the tally of Hang Seng Index constituents to 93 from 90, with no deletions this round.

Meanwhile, Hansoh Pharmaceutical and Akeso will join the Hang Seng China Enterprises Index of mainland Chinese companies trading in Hong Kong. The Hang Seng Index has remained little changed this year after a 28% gain in 2025 that made it one of the world's best-performing equity benchmarks. However, the energy shock from the US-Israel war on Iran and concerns about weak results from China's big tech platforms have weighed on sentiment. The compiler aims to expand the blue-chip index to 100 constituents over time, and these additions signal Hong Kong's commitment to capturing high-growth AI names.
