Chinese companies have delivered their strongest quarterly earnings in nearly five years — yet the stock market responded with indifference, followed by a sell-off.

Onshore-listed Chinese firms reported a 25.7% year-on-year profit increase in the second quarter of 2026, a figure that would ordinarily prompt celebration among investors. Instead, the CSI 300 Index — the benchmark that tracks the largest stocks listed in Shanghai and Shenzhen — fell roughly 9% over the same period, while the tech-heavy Star 50 Index plunged 29%. The disconnect underscores a broader pattern seen in AI booms elsewhere: when valuations run ahead of fundamentals, even record earnings can disappoint.

AI Is Driving the Gains

IT sector profits surged 142% year-on-year in Q2 2026, fueled by the rapid commercialization of artificial intelligence across hardware, semiconductors, and enterprise applications. Electronics companies followed closely, with profits climbing approximately 97% on demand for AI computing infrastructure — demand that has been global, as cloud providers and governments outside China also race to build out computing capacity.

Goldman Sachs estimated overall Chinese corporate profit growth at roughly 24% for the quarter, describing it as a five-year high. The investment bank noted that AI momentum is now shifting from a pure hardware buildout phase into broader enterprise applications — a transition that mirrors the trajectory seen among US technology giants, where the initial surge in chip and data-center spending gradually spread into software and services.

SenseTime, the AI-focused company that had been losing money for years, turned profitable during the quarter.

For the first half of 2026, industrial enterprise profits reached approximately 4 trillion yuan, an increase of 18.7%.

A Tale of Two Economies

Domestic consumption remains sluggish. The real estate sector continues to weigh on household wealth and consumer confidence — a drag that has persisted since the sector's downturn began in 2021. Internet companies faced mounting pressure as growth in their core advertising and e-commerce businesses showed signs of fatigue.

AI-linked export revenue has been a bright spot, with Chinese semiconductor and hardware firms capitalizing on global demand for computing power. That strength, however, coexists with a domestic economy that still has not gained traction in consumer spending. The result is an unusually lopsided earnings picture: a narrow set of AI-exposed sectors posting explosive growth while much of the consumer-facing economy stagnates.

Why Stocks Fell Anyway

The Star 50 Index's 29% decline is especially striking in context. The index, which lists on Shanghai's Nasdaq-style STAR Market and skews toward semiconductor and hard-tech names, had previously surged 76%, riding a wave of AI enthusiasm that swept through Chinese technology stocks.

Capital expenditure across China's AI sector has been enormous, with companies pouring billions into data centers, chip fabrication, and computing infrastructure. The profits are real, but so are the bills. Investors appear concerned that the current pace of spending could compress margins even as revenue grows.

After a 76% run-up, many AI-linked stocks were priced for perfection. A 142% profit increase in the IT sector is impressive, but when a stock already reflects expectations of that magnitude, even strong results can trigger profit-taking.

What to Watch From Here

The 18.7% industrial profit growth for the first half of the year suggests the non-AI economy is not collapsing. The gap between AI winners and everyone else is widening, and positioning in Chinese equities increasingly requires selecting specific segments rather than buying the index.

Going forward, the durability of the earnings surge will hinge on verifiable signposts: whether enterprise AI adoption broadens beyond hardware, whether heavy capital spending translates into sustained returns, and whether consumer demand stabilizes enough to narrow the two-speed gap.

The most telling number of the quarter is not the 25.7% profit growth or the 9% index decline — it is the 29% drop in the Star 50 following a 76% surge.
