The upcoming inclusion of two Chinese artificial intelligence companies, Knowledge Atlas Technology and MiniMax, is expected to boost the underperforming Hang Seng Tech Index by over $1 billion, according to Morgan Stanley. The technology stock index has fallen more than 11% so far this year despite excitement over Chinese AI, with only seven of the index's constituents expected to rise in 2026. The companies' shares have surged since they went public in Hong Kong in January. The cost of accessing Chinese AI models has risen as more people use these tools, rising to at least 17% of what U.S. AI models charge, up from 5% the previous year. The Morgan Stanley analysts predict that each of the frontier Chinese AI model can achieve at least $1bn in revenue this year and more than double that next year.
