Baidu reported another quarterly revenue decline on Tuesday, extending a streak of falling sales as weakness in its traditional advertising business continued to outweigh growth from artificial-intelligence services. The results highlight the difficult transition facing one of China’s biggest internet companies as it tries to turn heavy investment in AI into a meaningful new source of growth.
Baidu’s second-quarter revenue fell 4% from a year earlier to 31.33 billion yuan, or about $4.65 billion. The figure missed the average analyst estimate of 31.96 billion yuan, adding to concerns about the company’s ability to stabilize its core business while competing in China’s rapidly developing AI market.
The disappointing result sent Baidu’s U.S.-listed shares lower in premarket trading, with the stock falling about 3.5%. Investors were particularly concerned that the company’s AI-related growth was not yet strong enough to compensate for the deterioration in its established advertising business.
Baidu’s online marketing services revenue dropped 19% to 13.1 billion yuan during the quarter. The advertising business has been hurt by weak consumer spending and the prolonged downturn in China’s property sector, which has encouraged companies to reduce marketing budgets.
The weakness also reflects changes in China’s e-commerce market. During the country’s major 618 shopping festival, some e-commerce platforms shifted advertising and promotional spending toward direct subsidies for consumers rather than spending designed to generate traffic. That change reduced demand for the type of advertising services that have traditionally generated substantial revenue for Baidu.
The pressure on advertising is particularly important because Baidu built much of its business around search. For years, the company benefited from its dominant position in Chinese internet search, allowing it to monetize users through advertising and related services.
That model is now facing pressure from several directions. Consumers increasingly use short-video platforms, social networks and AI-powered tools to discover information, products and services. At the same time, generative AI is changing how people interact with search engines, creating uncertainty about whether traditional search advertising will remain as powerful as it was in the past.
Baidu is attempting to respond by investing heavily in artificial intelligence. Its AI cloud business has continued to expand, and the company has been repositioning itself around AI-powered search, cloud computing and autonomous-driving technology.
However, the latest numbers show that the transition is taking time. AI-related businesses are growing, but not quickly enough to offset the decline in legacy advertising revenue.
The challenge is not unique to Baidu. China’s major technology companies are all competing to establish positions in artificial intelligence, while investors are becoming increasingly demanding about the financial returns from those investments. Companies must spend heavily on computing infrastructure, research and talent before they can establish whether AI products will generate sustainable profits.
Baidu has attempted to address that challenge by reducing costs while redirecting resources toward AI. Earlier in 2026, the company reported strong growth in its AI-powered business, with AI-related revenue becoming an increasingly large part of its broader operations. In the first quarter, Baidu’s general business revenue remained broadly stable despite a 22% decline in online marketing services, helped by growth in its other businesses, particularly AI cloud.
The company has also been developing its own artificial-intelligence infrastructure. Its Kunlunxin chip business is being prepared for a separate listing, a move that could potentially unlock value for shareholders while giving the semiconductor operation greater independence and access to capital. Baidu has also introduced a large share-repurchase program and its first dividend policy, signaling an effort to return capital to investors while continuing to fund AI development.
The problem for investors is that AI growth needs to become large enough to change Baidu’s overall financial trajectory. The company cannot rely indefinitely on declining advertising revenue being replaced by businesses that are still relatively young.
Competition is also intensifying. Chinese technology giants including Alibaba, Tencent and ByteDance are investing heavily in AI models and applications, while specialized companies are developing increasingly capable systems. Baidu’s early investment in generative AI gave it an important head start, but maintaining that advantage is becoming more difficult as the market becomes crowded.
The company’s AI cloud operation provides one of the clearest potential growth opportunities. Demand for computing resources is increasing as businesses experiment with AI applications, while Chinese companies are looking for domestic alternatives to foreign technology amid continuing restrictions on advanced semiconductor exports.
Yet cloud growth can also require substantial capital spending. AI infrastructure is expensive, and the returns on those investments may take years to materialize. That creates a difficult balance for Baidu between protecting short-term profitability and funding the technology needed to compete over the long term.
The latest earnings therefore present a mixed picture. Baidu is not abandoning its AI strategy, and some parts of the business are growing rapidly. But the traditional revenue engine is weakening faster than the new businesses can currently compensate.
That makes the company’s next phase particularly important. If AI-powered search, cloud services and other new products begin generating significant revenue, Baidu could eventually transform its business and reduce its dependence on advertising. If those businesses grow too slowly, however, the company could remain trapped between a declining legacy model and an AI strategy that requires large investments without delivering sufficient returns.
The broader Chinese economy adds another layer of uncertainty. Weak consumer demand and continuing problems in the property sector are affecting corporate spending, making it harder for advertising-dependent companies to recover quickly.
For now, Baidu’s fifth consecutive sales decline sends a clear warning: its AI transition has not yet reached the scale required to overcome weakness in its core business. The company has significant technology assets, a large user base and substantial AI ambitions, but investors are increasingly looking for evidence that those advantages can translate into sustained financial growth.
The next test will be whether AI cloud and other AI-powered businesses can accelerate enough to offset continued weakness in advertising. Until that happens, Baidu’s AI strategy will remain more of a promise than a proven replacement for its traditional search business.
The latest results therefore leave Baidu at a critical point. Its future growth may depend on artificial intelligence, but the company’s present financial performance is still being determined largely by the business AI is supposed to replace.
