China's AI stock bubble has burst, with $340 billion in market cap losses. Since its peak in late June, China’s Star 50 AI stock index has declined 42%, drastically underperforming the Nasdaq 100 index's 1.5% decline over the same period. MiniMax shares closed 87% below their earlier high, and Unisound experienced a similar drawdown. An unnamed partner at Shanghai Zhuozhu Investment Management stated that all bubbles inevitably burst, while Lotus Asset Management's Hong Hao warned that many mainland AI stock listings are being paused.
