Hang Seng Tech Index adds 2 AI firms in 267 billion yuan rebalancing

The Hang Seng Tech Index will admit its first pure AI large model stocks, marking a milestone for Hong Kong's technology benchmark.

The Hang Seng Tech Index will add Zhipu (智谱) and MiniMax on June 8, giving the two AI companies a combined initial weight of 0.89 percent.

Hang Seng Indexes Company said the inclusion makes Zhipu and MiniMax the first pure AI large model stocks in the benchmark's history. The two companies will enter with initial weights of 0.53 percent and 0.36 percent, respectively.

The rebalancing affects 31 index-tracking products with 267.2 billion yuan ($36.9 billion) in assets under management, forcing fund managers to buy the stocks as they adjust portfolios to match the new composition. The total represents the combined size of all passive funds tracking the index.

The move sets a precedent for AI companies seeking index inclusion in Hong Kong, potentially attracting more capital to the sector. As the Hang Seng Tech Index evolves beyond its traditional e-commerce and gaming heavyweights, the addition of pure-play AI model developers signals a shift in how the benchmark defines technology leadership. The inclusion could also encourage other AI firms to pursue Hong Kong listings, broadening the city's appeal as a destination for technology capital.
