Key Bullets
- China's Star 50 AI stock index plunged 42% since late June while the broader CSI 300 tech sector dropped 18%.
- Hong Kong shares of AI model developer MiniMax closed trading down 87% from their HK$1,330 high earlier this year.

Star 50 Index Plunges 42% Locally
China's domestic AI equity bubble suffered a severe correction Tuesday morning after public financial data confirmed the Star 50 AI stock index plummeted 42% since its late June peak. Performance tracking compiled by exchange data providers showed the CSI 300 tech sector sliding 18% over the identical timeframe. Both mainland indices drastically underperformed the modest 1.5% benchmark drop recorded by the Nasdaq 100 index across the corresponding operational period. Exchange order-book depth monitored by Protos revealed widespread selling pressure among heavy mainland constituents.
Publicly traded AI firms anchored in mainland operations drove the severe downward repricing across Hong Kong and Shanghai venues. Financial filings indicate that combined market capitalization losses for 14 major Chinese AI corporations reached $340B below their respective 2026 highs. Data audits confirmed that only three out of the 14 tracked enterprises managed to limit their total drawdown below 50%. Market liquidity dried up entirely.
MiniMax Shares Crash 87% Downward
AI model developer MiniMax led the regional carnage as shares closed trading in Hong Kong down 87% from an earlier high of HK$1,330. Competitor Unisound registered an identical structural drawdown from its yearly peak established during the first quarter. Financial disclosures from corporate registries show that retail and institutional capital exits accelerated sharply once key valuation supports broke. Trading desks scrambled to reprice risk parameters.
Shanghai Zhuozhu Investment Management partners confirmed the sweeping capital flight away from speculative mainland tech equities. Lotus Asset Management strategist Hong Hao stated publicly that numerous mainland AI stock listings faced immediate regulatory suspensions. Bank of America analyst Alex Liu told Bloomberg reporters that survival metrics remain completely uncertain for remaining sector participants. AI assets still account for roughly 40% of the entire domestic stock market.
