Artificial intelligence shares in Hong Kong opened higher on Aug. 12, led by Haizhi Technology Group's 12.50% gain, while Zhipu and MiniMax climbed nearly 7% and 5%, respectively. Zhongke Wenge rose 4.74% and Biren Technology added 4.76%. The move came after HKEX announced that MiniMax had met the fast inclusion rule for the HKEX Technology 100 Index and will be added to both the HKEX Technology 100 Index and the HKEX Technology and U.S. Technology 100 Index after the market close that day, with the change officially taking effect from Aug. 13, 2026. Index additions are closely watched because benchmark-linked investors often adjust holdings around inclusion dates.
