Why is Baidu stock sliding today?

Baidu's stock is experiencing a decline of 4.1% in early trading after the company's second-quarter 2026 results disappointed analysts across the board. The report, released ahead of the U.S. market open on August 18, 2026, revealed that earnings per share fell to RMB7.22, underestimating the consensus estimate of RMB9.84. Meanwhile, revenue of RMB31.33 billion lagged behind the projected RMB31.95 billion and declined by 4% year-over-year.

The most significant issue lies within Baidu's advertising business, which generated 13.1 billion yuan during the quarter, marking a 19% drop compared to the previous year. This drop has persisted for four consecutive quarters, with core advertising revenue slipping between 15% and 21% year-over-year. Analysts attribute the decline to users shifting away from traditional search to AI chatbots.

However, AI Cloud Infrastructure revenue surged by 50% year-over-year to RMB7.3 billion, buoyed by GPU Cloud revenue. Analysts have adjusted their price targets accordingly. Barclays analyst Jiong Shao reduced his price target, while BofA analyst Miranda Zhuang lowered her target from $180 to $165, while maintaining a Buy rating.

Adjusted operating profit forecasts for Baidu's core business have been cut by 3% to 8% due to weaker advertising performance and increased AI investment. The general market sentiment also contributed to the pressure, with both the Nasdaq composite and S&P 500 showing declines. As the broader geopolitical landscape casts a shadow over Chinese tech companies, Baidu's shares are currently trading at $99.9 in pre-market, close to the lower end of its 52-week range, as investors weigh the pace and profitability of the company's shift towards an AI-first platform.
