Baidu's 1Q26 AI cloud infrastructure delivered strong performance, with AI business revenue exceeding half of core business revenue

Overview

This is a Morgan Stanley company research/earnings review report on Baidu Inc's 1Q26 results. The core view is that Baidu's AI cloud infrastructure revenue materially beat expectations and the share of AI-related business within core operations continued to rise; meanwhile, traditional core marketing remained under pressure, and rising capex from AI investments also warrants continued monitoring.

Core views

The report argues that the main positives in 1Q26 results came from AI Cloud Infra and better-than-expected non-marketing business. Baidu general business revenue increased 2% YoY, 3% above Morgan Stanley's estimate; AI-related revenue was Rmb13.6bn, accounting for 52% of Baidu general business revenue. However, core marketing revenue declined 21% YoY, suggesting that search and advertising monetization is still affected by the cycle, competition, or AI migration. Overall, AI infrastructure growth strengthens Baidu's long-term narrative, but short-term earnings quality and a recovery in traditional business remain key to any rating upgrade.

Analysis framework

The report mainly uses earnings comparison and segment breakdowns, comparing total revenue, Baidu core, core marketing, non-marketing, AI-related business, AI Cloud Infra, AI apps, and AI marketing against YoY changes and Morgan Stanley estimates; on valuation, it uses a sum-of-the-parts framework, with core business valued using DCF and associate investments valued using implied market valuation with a discount.

Methodology notes

• valuation methodsum of the parts

  sum-of-the-parts valuation

  The report's base case uses sum-of-the-parts valuation, separately valuing the core business and associate investments before combining them to reflect the value sources of Baidu's different business assets.

• valuation methodDCF

  discounted cash flow

  Core business valuation is US$126/share, using an 11% discount rate and 3% perpetual growth rate.

• valuation methodimplied market valuation with discount

  discounted associate investment valuation

  Associate investments such as TCOM and IQ are valued based on implied market valuation, with a 30% discount applied to the investment value, corresponding to US$9/share.

• AI Cloud Infra

  the main business driver behind the earnings beat

  Strengths

  Revenue was Rmb8.8bn, up 79% YoY, and subscription revenue grew 184% YoY.

  Weaknesses

  Growth depends on continued capex and customer adoption, which may pressure free cash flow or margins in the near term.

  Risks

  Slower-than-expected adoption of AI-related services in China, and pricing or margin pressure from competition.

• core marketing

  traditional core business drag

  Strengths

  If the core business recovers, it will be an important driver in an upside scenario.

  Comparison

  The divergence from non-marketing business at +42% highlights a changing growth mix within Baidu's core business.

  Comparison

  Relative to the core business at US$126/share, associate investments account for a smaller share of total value.

  Risks

  Volatility in investee share prices, widening discounts, or repricing of investment value.

Impact & implications

For investors, the report reinforces Baidu's core narrative of transitioning from traditional search advertising toward AI infrastructure and AI-driven businesses. The rapid growth of AI Cloud Infra and the rising AI business mix help support the long-term valuation, but declining core marketing, higher capex, and the potential impact of AI on the search business model mean near-term risks have not yet disappeared. If AI cloud subscription revenue continues to scale, while traditional core business recovers and margins improve, the upside for the stock price and valuation re-rating will become clearer.

Risks

• Intensifying competition in search and online video could raise TAC and force more aggressive content investment.
• If AI-related adoption in China does not continue to scale, the growth narrative for AI cloud infrastructure could weaken.
• AI poses a disruption risk to the search business, which could affect traditional core marketing revenue and monetization pathways.
• Rising capex for AI infrastructure could pressure cash flow and margins.
• If the core business recovery falls short of expectations, revenue growth and valuation upside may be limited.

What to watch

• Whether AI Cloud Infra revenue and subscription revenue can sustain high growth.
• Whether the share of AI-related revenue in Baidu general business continues to rise.
• Whether the YoY decline in core marketing revenue narrows or returns to growth.
• Whether Baidu core non-GAAP operating margin can remain stable during the AI investment cycle.
• Capex intensity and its impact on cash flow, buybacks, and margins.
• Whether AI apps, AI marketing, and robotaxi initiatives enter a stage with verifiable revenue or profit contribution.
• Changes in search and online video competition, TAC, and content investment.
