Baidu Swings to Loss on Impairment Charge as AI Growth Masks Core Weakness

Baidu posted a significant third-quarter net loss despite surging growth in its artificial intelligence businesses, underscoring the high cost and strategic urgency of its pivot away from a declining core advertising operation.

The Chinese search giant reported a net loss of 11.2 billion yuan (approximately US$1.56 billion) for the three months ended September, a sharp reversal from a profit in the same period last year. The loss was driven by an 18% plunge in its core online marketing revenue and a massive 16.2 billion yuan impairment charge on long-term assets. Total revenue for the quarter fell 7% year-over-year to 31.2 billion yuan.

In a stark contrast, Baidu’s AI-related businesses showed robust momentum. For the first time, the company detailed its AI revenue, which topped 10 billion yuan, a more than 50% increase from a year earlier. The disclosure highlights the company's efforts to build a new growth narrative centered on generative AI and cloud computing.

Investors appeared to focus on the AI potential over the current-quarter loss, with Baidu’s stock price rising in the wake of the earnings announcement. The market reaction signals confidence in the company’s AI-centric strategy, even as it navigates a painful transition that executives have described as a "must-win battle."

AI Becomes a Growth Engine

Baidu’s quarterly report provided the first detailed breakdown of its AI business, which is now comprised of three main segments. AI-native marketing services, including AI agents and digital humans, were the standout performer, with revenue skyrocketing 262% year-on-year to 2.8 billion yuan. Baidu’s Smart Cloud infrastructure unit saw revenue grow 33% to 4.2 billion yuan, with subscription revenue for its AI high-performance computing facilities jumping 128%. The third segment, AI applications like Baidu Wenku and Baidu Wangpan, saw revenue increase by a more modest 6% to 2.6 billion yuan.

The company is also aggressively integrating AI into its legacy products. As of October 2025, approximately 70% of mobile search result pages on Baidu contained AI-generated content. Its flagship Baidu App saw monthly active users rise 1% to 708 million in September. Meanwhile, its autonomous driving unit, Apollo Go, serviced 3.1 million fully driverless rides in the quarter, a 212% acceleration in year-on-year growth.

Core Business Under Pressure

The growth in AI was not enough to offset the accelerated decline in Baidu’s traditional cash cow. Core revenue, which excludes its streaming unit iQIYI, fell 7% to 24.7 billion yuan. The main driver of the decline was online marketing services, where revenue fell 18% to 15.3 billion yuan.

While non-online marketing revenue, which includes the cloud business, grew 21% to 9.3 billion yuan, the expansion was insufficient to make up for the double-digit slide in advertising. This widening gap between the shrinking core business and the growing new ventures highlights the challenge Baidu faces in funding its AI ambitions.

Explaining the Deep Loss

The direct cause of the steep quarterly loss was a 16.2 billion yuan impairment on what Baidu called its "core asset group." The company did not offer extensive details in its report, but Baidu Vice President He Junjie explained on an earnings call that the charge was a proactive writedown of assets that no longer meet the company's evolving needs for high-efficiency AI computing. "This one-time impairment will optimize the company's asset structure," He said. Excluding the charge, Baidu would have recorded an operating profit of 1.1 billion yuan.

The loss was also exacerbated by rising expenditures. Cost of sales grew 12% to 18.3 billion yuan, primarily due to expenses related to the smart cloud business. Selling and administrative expenses also increased 12% to 6.6 billion yuan.

Doubling Down on AI

Despite the bottom-line pressure, Baidu is intensifying its commitment to artificial intelligence, having invested over 100 billion yuan in the field since ahe launch of its Ernie foundation model. In November 2025, the company unveiled Ernie 5.0, its latest native multimodal foundation model.

Baidu's founder and CEO, Robin Li, stated that no single model will dominate all fields, and the company will remain focused on maintaining a leading edge in areas closely related to its business portfolio. Speaking on the earnings call, Executive Vice President Luo Rong outlined commercialization plans for AI-powered search, including testing e-commerce components, generating over 25 million yuan in daily revenue from AI agents for advertisers, and utilizing digital human-led livestreams.
