Chinese AI Stocks Rally as OpenAI's 'Astra' Model Boosts Sector Sentiment
Chinese artificial intelligence stocks posted broad gains on Friday, lifted by renewed investor enthusiasm following OpenAI's announcement of its new flagship model, dubbed Astra. The development spurred a rally across the sector as traders assessed the accelerating pace of AI capabilities and its implications for domestic companies.
Sector-Wide Gains
Shares of AI model developer MiniMax led the advance, climbing 6.5% to close at HK$378, according to a report from Investing.com. Other major technology and AI-related stocks also rose sharply:
- Baidu (9888.HK) gained 4.6%.
- Kuaishou Technology (1024.HK) was up 4.2%.
- JD.com (9618.HK) rose 4.1%.
- Xiaomi (1810.HK) increased 3.9%.
The positive sentiment provided a tailwind for the broader market, with Hong Kong's Hang Seng Tech Index opening up 1.5%.
OpenAI Catalyst
AdThe rally came the day after OpenAI unveiled Astra, which it reportedly positioned as its most powerful model to date. The model is described as being capable of executing complex tasks directly within computer and browser environments, marking a significant step toward more autonomous AI agents.
This announcement served as a fresh market signal for China's own AI developers. It has intensified investor focus on the commercialization potential of large language models (LLMs) and related AI agent services, boosting overall market sentiment.
Spotlight on Domestic Players
MiniMax and Zhipu AI are seen by investors as two of the primary publicly-traded beneficiaries of the AI boom in China. The recent rally is also supported by strong underlying performance, with Zhipu AI reporting first-half revenue growth of nearly 400% year-over-year to RMB 953.9 million.
Investor appetite for MiniMax has been particularly strong. Data from Wind showed that mainland investors purchased a net HK$10.1 billion worth of MiniMax shares in August through the Stock Connect program, ranking it as the most-bought Hong Kong stock by mainland traders during the period.
