Chinese AI Stocks Rise as OpenAI's 'Astra' Launch Boosts Sector Sentiment
Chinese artificial intelligence stocks rallied on Friday, lifted by positive sentiment following the launch of OpenAI's latest model, GPT-6 Astra. The development provided a fresh catalyst for the sector, with investors assessing the implications of advancing AI capabilities for domestic technology companies.
Broad-Based Rally in Tech
The gains were widespread among major Chinese tech and AI-focused firms. According to Investing.com, key movers included:
- MiniMax shares, which jumped 6.5% to HK$378.
- Baidu Inc. (9888), which gained 4.6%.
- Kuaishou Technology (1024), which advanced 4.2%.
- JD.com (9618), which climbed 4.1%.
- Xiaomi Corp. (1810), which rose 3.9%.
Zhipu AI, also known as Z.AI, saw a marginal increase to HK$1,108. The rally was supported by a broader positive market backdrop, with Hong Kong's Hang Seng Tech Index opening up 1.5%.
OpenAI's Advance as a Sector Catalyst
AdThe immediate trigger for the rally was OpenAI's release of Astra, which the company described as its most capable model to date. The model is designed to perform complex tasks within computer and browser environments, a key step toward the development of more autonomous AI agents.
For investors, the launch offers a positive read-through for the commercial potential of large language models and AI-agent services being developed by Chinese firms. Companies like MiniMax and Z.AI are seen as leading listed beneficiaries of China's own rapidly growing AI industry, and advances from global peers often renew interest in their long-term value proposition.
Strong Fundamentals and Investor Interest
The recent stock gains build on a period of strong performance for China's leading AI players. Z.AI reported a nearly 400% year-over-year surge in first-half revenue to 953.9 million yuan, while MiniMax posted revenue growth of 283% for the same period.
Investor appetite for the sector has remained robust. Data compiled by Wind showed that mainland Chinese investors purchased a net HK$10.1 billion of MiniMax shares through the Stock Connect program in August. This marked the largest net purchase among Hong Kong-listed companies available to onshore investors for the month.
