Bloomberg Estimates $2.4 Trillion Lost From Chinese Stocks Since May, Led by AI Firms

About $2.4 trillion has been wiped from China's stock market since May 2026, according to Bloomberg. Losses have concentrated in artificial intelligence (AI) companies, which Goldman Sachs says make up over 40% of stock market value in China and Hong Kong. The STAR 50 index, which tracks Shanghai-listed tech firms, has fallen 40% since June 2026.
