China's AI Market Corrects Sharply While Industrial Foundations Expand

China's AI sector has experienced a dramatic market pullback, with valuations crashing 40% and billions in market value evaporating, yet substantial evidence suggests the underlying industrial foundation remains robust despite headline-grabbing declines. The mainland STAR 50 index of AI and semiconductor companies fell 40 percent in less than four months, wiping out approximately $480 billion in market capitalization. Valuation multiples compressed from nearly 250 times trailing earnings to around 100 times, compared to the Nasdaq 100's 30 times multiple. Venture capital deployment into Chinese AI startups dropped 67 percent year-over-year, falling from $18.4 billion in the first nine months of 2025 to just $6.1 billion in the same 2026 period, with major firms including DeepSeek, Zhipu AI, and MiniMax reporting valuation cuts of 40–60 percent in recent funding rounds.
