China Stocks Shed $2.4 Trillion Since May as Investors Doubt AI Profitability

Mainland Chinese stocks have lost roughly $2.4 trillion in market value since May, as investors grow skeptical that the country's artificial intelligence boom will translate into real profits. The selloff reflects deepening concerns over the financial viability of Chinese AI companies, many of which face rising costs and uncertain revenue streams. U.S. restrictions on technology exports have further clouded the outlook, limiting access to advanced chips and other critical components, while high U.S. interest rates continue to draw global capital away from emerging markets. These combined pressures have left investors questioning whether China's AI ambitions can sustain the lofty valuations seen earlier this year. For the world's second-largest economy, the rout signals a potential reassessment of its tech sector's growth story. As policymakers weigh stimulus measures, market participants are watching for signs of regulatory support or clearer paths to monetization. The coming months will test whether China's AI leaders can deliver earnings that justify renewed confidence, or if the market's doubts mark the start of a longer correction.
