China's technology sector has experienced a significant surge in artificial intelligence (AI) activity and stock market gains over the past six months, according to CNBC's The China Connection newsletter [1]. The AI boom has been visible in public spaces, with widespread advertising and consumer engagement, ranging from AI chatbot wars during the Lunar New Year to the popularity of AI-generated videos and the rise of new AI agents like OpenClaw [1]. A notable market event was the brief shutdown of Anthropic's Mythos and Fable models in the U.S., which contributed to the rapid ascent of Knowledge Atlas (also known as Z.ai) into the trillion-Hong Kong dollar market cap club after it released the open-source GLM 5.2 model, which achieved top performance in coding benchmarks while Fable was offline [1].
Tech stocks now account for approximately 30% of the mainland China A-share market, and their recent gains are providing support to the struggling property sector in major Chinese cities, according to Nomura's chief China economist Ting Lu [1]. The market is also seeing a wave of new IPOs, including the autonomous driving company Momenta, which is set to list in Hong Kong, mirroring the excitement seen in the U.S. around high-profile listings [1].
On the diplomatic front, U.S. President Donald Trump visited Beijing in May after a delay caused by the Iran war, an event described as the most-anticipated of the first half of the year [1]. This visit helped maintain a thaw in U.S.-China relations, prompting U.S. businesses to increase orders from Chinese suppliers ahead of a stricter tariff regime scheduled to begin later in the month [1]. Looking ahead, Chinese President Xi Jinping is expected to visit the U.S. in late September, and a Trump-Xi meeting is anticipated during the APEC summit in November, following the U.S. midterm elections [1].
Despite the current optimism, there are questions about whether market enthusiasm is running too high, especially as the summer holidays in China, which began on July 1, may signal a temporary lull before further market developments [1].
CONCLUSION
China's AI-driven tech rally and a robust IPO pipeline are providing crucial support to the broader market, even as uncertainties around tariffs and consumer spending persist. Diplomatic engagements between the U.S. and China have contributed to market stability, but investors remain watchful for potential volatility after the summer lull.
