01 Running thesis

AI is now the main story

Baidu has crossed a real marker. In Q1 2026, its core AI-powered business was 52% of Baidu General Business revenue. Baidu General Business revenue was RMB 26.0 billion, up 2% year over year, after several quarters of pressure.

The best part of the story is AI infrastructure. GPU Cloud revenue grew 184% year over year. Management also said GPU Cloud has structurally better margins than traditional CPU Cloud, meaning each yuan of revenue can be more profitable if demand holds.

Apollo Go adds another long-term option. The robotaxi unit delivered 3.2 million fully driverless rides in Q1, is testing or preparing tests in London and Switzerland, and is operating in Dubai. Wuhan has reached unit economics breakeven, which means each ride can cover its direct operating costs in that city.

The bear case is still serious. Legacy online marketing remains weak, AI search can hurt ad revenue before it helps, and the company is spending heavily on AI chips, models, cloud capacity, and robotaxis. The score is only middling because Baidu must prove that this large AI buildout can earn strong returns, not only faster revenue growth.

May 2026▲Q1 2026 showed a clear AI milestone: core AI-powered business reached 52% of Baidu General Business revenue, while General Business revenue returned to 2% year-over-year growth. GPU Cloud revenue grew 184%, and management said GPU Cloud has a structurally better margin path than CPU Cloud.

Mar 2026▲The 2025 Form 20-F added a shareholder return catalyst. Baidu’s board approved a dividend policy, with the first payment expected in 2026.

Feb 2026▲Q4 2025 strengthened the AI transition case, with AI-powered business at 43% of Baidu General Business revenue and AI accelerator infrastructure revenue up 143% year over year. The proposed Kunlunxin spin-off added a possible way to surface hidden asset value.

Nov 2025▼Q3 2025 showed sharper pressure in the legacy ad business, with Baidu Core online marketing revenue down 18% year over year. AI-native marketing grew quickly, but not enough to erase the near-term margin and revenue drag.

Aug 2025→Q2 2025 was mixed. Apollo Go gained global Uber and Lyft partnerships, and AI ad products scaled, but legacy online marketing fell 15% year over year and AI search monetization remained early.

May 2025→Q1 2025 showed a split business. AI Cloud revenue grew 42% year over year and agents became 9% of online ad revenue, while core online marketing still fell 6% year over year.

Mar 2025▼The 2024 Form 20-F confirmed Baidu acquired YY Live for about US$2.1 billion in February 2025. The deal adds a live-streaming asset, but it also creates integration and execution risk.

Feb 2025→Q4 2024 widened the gap between AI growth and legacy weakness. AI Cloud grew 26% year over year, while Baidu Core online marketing fell 7% year over year and AI search was not yet monetized at scale.

02 Business model

Search cash funds the AI build

Baidu still makes money from search and online marketing in China. It is moving from cost-per-click ads, where advertisers pay for clicks, toward cost-per-sale ads, where Baidu gets paid when AI agents or digital humans help close a sale.

The growth engine is Baidu AI Cloud. Customers rent computing power, especially GPU cloud capacity, to train and run AI models. Baidu also sells model and agent tools through platforms such as Tianfan MoS, ERNIE, Miaoda, Comate, Yijian, and Famou Agent.

Consumer AI is another route. Baidu Search is adding generative AI answers, DuMate helps users complete tasks, and PSIG combines Baidu Wenku and Baidu Drive into a larger personal AI group. These products may become ad, subscription, or usage-based businesses over time.

The model breaks if old search ad revenue falls faster than AI revenue can replace it. It also breaks if AI cloud needs too much capital, robotaxis scale too slowly, or domestic AI chips cannot keep up with real customer demand.

03 Product portfolio

From search box to AI stack

Cash cow

Baidu Search

Baidu Search is the legacy core. It now uses ERNIE 5.1 and AI-generated results, but that shift can pressure ad sales while the new format is still being monetized.

Growth engine

Baidu AI Cloud

AI Cloud sells compute and tools to companies building and running AI. AI Cloud revenue reached RMB 11.3 billion in Q1 2026, helped by fast GPU Cloud growth.

Growth engine

ERNIE and Tianfan MoS

ERNIE is Baidu’s foundation model family. Tianfan MoS hosts ERNIE and third-party models, giving customers one place to use popular Chinese AI models.

Option

DuMate, Miaoda, and Famou Agent

These are Baidu’s agent and productivity bets. They aim to turn AI from chat into work, such as coding, office tasks, and complex enterprise decisions.

Option

Apollo Go

Apollo Go is Baidu’s autonomous ride-hailing service. It is scaling fully driverless rides in China and moving into Europe and the Middle East.

Option

Kunlunxin

Kunlunxin is Baidu’s own AI chip business. A proposed spin-off and separate listing could make this asset more visible to investors.

Steady

iQIYI and YY Live

iQIYI is Baidu’s online video business, and YY Live adds live-streaming. These assets broaden the company, but YY Live brings integration risk after the 2025 acquisition.

04 Business segments

Q1 revenue is mostly core Baidu

Baidu General Business81%modest

iQIYI19%declining

The mix uses Q1 2026 revenue from the earnings call: Baidu General Business revenue of RMB 26.0 billion and iQIYI revenue of RMB 6.2 billion, out of total Baidu revenue of RMB 32.1 billion. Baidu General Business excludes iQIYI and includes search, marketing, AI cloud, AI apps, Apollo Go, and related businesses.

05 Risk factors

What could still break

Legacy ads keep shrinking

High impact · High odds

Baidu’s old search ad engine remains under pressure from a weak consumer backdrop and user time moving to short video platforms. Even with total General Business revenue back to growth, a falling ad base can hide real weakness under faster AI lines.

We watchBaidu Core online marketing revenue growth and the share of online marketing revenue from AI-native ad services.

AI spending outruns cash returns

High impact · Medium odds

Management has pointed to more than RMB 100 billion invested in AI since March 2023. Operating cash flow was positive at RMB 2.7 billion in Q1 2026, but heavy AI capacity, models, and chips can still weigh on free cash flow and return on invested capital.

We watchOperating cash flow, capital expenditure, AI Cloud margins, and management comments on return on investment.

AI search hurts ads before it helps

Medium impact · High odds

AI-generated search results can improve the user experience, but they also change where ads fit on the page. If Baidu waits too long to monetize AI search, or users click fewer paid links, near-term revenue and margins can suffer.

We watchAI-generated search result penetration, ad load, click-through rates, and online marketing revenue trends.

Robotaxi scale stays expensive

High impact · Medium odds

Apollo Go is a large long-term option, not a proven profit pool at company scale. Wuhan unit economics breakeven is encouraging, but global launches need vehicles, mapping, safety operations, regulators, and local partners.

We watchFully driverless ride volume, new city permits, overseas test launches, and city-level profitability updates.

Domestic AI chips lag demand

Medium impact · Medium odds

Kunlunxin gives Baidu a supply and cost advantage if it works at scale. The open question is whether domestic AI chips can meet fast-growing inference demand and catch up in frontier training workloads where global chips still lead.

We watchKunlunxin capacity, customer adoption, cluster reliability, and management comments on chip supply.

YY Live integration disappoints

Medium impact · Medium odds

Baidu completed the YY Live acquisition in February 2025 for about US$2.1 billion. The asset may add live-streaming reach, but it can also distract management or fail to deliver the expected benefits.

We watchYY Live revenue contribution, user trends, impairment signals, and cost synergy updates.

06 Quick answers
