Baidu is widening access to its Hong Kong-listed shares among mainland Chinese investors just as its business is becoming increasingly centered on artificial intelligence. Effective September 7, the company’s Class A ordinary shares became eligible for both the Shenzhen-Hong Kong Stock Connect and Shanghai-Hong Kong Stock Connect programs, giving eligible mainland investors direct access through the two cross-border trading channels.
The timing is notable because Baidu is simultaneously shifting its business mix toward AI cloud infrastructure, foundation models, enterprise applications and autonomous driving.
Baidu’s Stock Connect Expansion Comes as AI Becomes Its Core Growth Engine
Baidu’s latest capital-markets move is about more than expanding its shareholder base.
The Chinese technology company has gained access to both major mainland-to-Hong Kong Stock Connect channels at a time when its investment story is increasingly tied to artificial intelligence.
Baidu’s Class A shares listed in Hong Kong became eligible for the Shenzhen-Hong Kong Stock Connect on September 7, following the previously announced inclusion in the Shanghai-Hong Kong Stock Connect. Eligible investors in mainland China can now access the company’s Hong Kong-listed shares through both programs.
The move should broaden the pool of mainland investors able to trade Baidu’s Hong Kong shares and potentially improve liquidity.
But the more interesting backdrop is what Baidu is doing with the business itself.
Baidu is becoming an AI-first company
Baidu has spent the past several years repositioning itself from an internet company with AI capabilities into a company where AI increasingly sits at the center of its commercial strategy.
That transition is visible in its latest financial results.
For the second quarter of 2026, Baidu reported RMB 12.5 billion in revenue from its core AI-powered business, representing 50% of Baidu General Business revenue.
AI Cloud Infrastructure generated RMB 7.3 billion, up 50% year over year. Within that segment, GPU Cloud revenue increased 283% year over year.
Those numbers make the Stock Connect development more relevant.
Mainland investors gaining easier access to Baidu’s Hong Kong-listed shares are doing so as the company increasingly resembles an AI infrastructure and applications business rather than a conventional search and advertising platform.
AI infrastructure is becoming the financial story
Baidu’s AI Cloud business is particularly important because it puts the company into competition for enterprise AI spending.
The company provides computing infrastructure, model services and development tools through Baidu AI Cloud and its Qianfan platform. Its broader AI stack includes computing infrastructure, the PaddlePaddle deep-learning framework, ERNIE foundation models and agent-development capabilities.
That vertically integrated approach matters as enterprises move from experimenting with large language models to deploying AI applications in production.
Baidu’s GPU Cloud growth offers one indication of that demand.
The company reported that GPU Cloud revenue increased 184% year over year in the first quarter of 2026 before accelerating to 283% growth in the second quarter.
For an AI company, cloud infrastructure can also provide a more direct monetization path than consumer AI products alone.
From models to agents
Baidu is also moving beyond the foundation-model race toward autonomous software.
The company launched DuMate, a general-purpose productivity agent, in March 2026. Baidu describes it as capable of executing complex, multi-step workflows across applications and files.
It has also continued developing its Qianfan platform around enterprise AI and agent workloads, while expanding model and development capabilities.
That puts Baidu within a broader industry transition from chatbots to AI agents.
The distinction is important.
A chatbot primarily responds to a request. An agent is designed to complete a sequence of tasks, potentially interacting with software, files and external systems along the way.
For enterprises, that creates a larger commercial opportunity—and a larger infrastructure requirement.
Agents need computing capacity, model inference, data access, security controls and orchestration. Baidu’s position across several of those layers gives it a way to capture value beyond model licensing.
ERNIE remains part of the stack
Baidu’s foundation-model strategy remains another component of the transition.
The company launched ERNIE 5.1 in May, with improvements to text capabilities, reasoning and model efficiency. Baidu’s current model portfolio also includes newer multimodal and reasoning models alongside its broader ERNIE ecosystem.
The competitive environment is intense.
Baidu is competing for developers and enterprise customers against domestic Chinese AI companies while also operating in a global technology environment dominated by companies such as Microsoft, Google, Amazon and NVIDIA.
That makes infrastructure and application integration increasingly important.
The winning strategy may not be simply producing the strongest model. It may be controlling enough of the surrounding stack to make AI deployment easier and more economical.
Autonomous driving adds another AI growth vector
Baidu’s AI ambitions also extend beyond cloud software.
Its Apollo Go autonomous ride-hailing platform continued international expansion in 2026. The company said its global footprint had reached 28 cities, with fleets accumulating more than 350 million autonomous kilometers, including more than 240 million fully driverless kilometers.
Apollo Go therefore gives Baidu exposure to another major AI market: autonomous systems.
The technology requires computer vision, machine learning, high-performance computing, mapping, simulation and real-time decision-making.
It also reinforces Baidu’s argument that its AI strategy is broader than a single foundation model.
Why the Stock Connect inclusion matters
The immediate effect of the Stock Connect inclusion is straightforward: more eligible mainland investors can access Baidu’s Hong Kong-listed shares.
The strategic effect is potentially broader.
Baidu is pursuing a voluntary conversion toward a dual-primary Hong Kong listing, with the company saying in August that the process was expected to become effective within 2026, subject to shareholder and Hong Kong Stock Exchange approvals.
Together, the listing transition and Stock Connect access point toward deeper integration with Hong Kong’s capital market.
For Baidu, that comes as the company is spending heavily on AI infrastructure while trying to convince investors that those investments can produce durable growth.
The company’s second-quarter numbers provide some evidence of that transition. AI Cloud Infrastructure grew rapidly, while traditional businesses remained under pressure. Baidu itself has described the shift as a move from an internet-centric company toward an AI-first company.
The next test is whether AI infrastructure, applications, agents and autonomous driving can generate enough growth to offset the decline of older businesses.
For investors gaining easier access through Stock Connect, that is likely to be the more important question than the mechanics of the inclusion itself.
Market Landscape
Baidu’s Stock Connect inclusion arrives during a broader restructuring of China’s technology sector around AI infrastructure and applications.
The competitive landscape now extends across several layers:
- Foundation models: Baidu ERNIE and competing Chinese models.
- AI cloud: GPU computing, inference and enterprise AI infrastructure.
- Agent platforms: Tools for deploying autonomous workflows.
- AI applications: Productivity, search, content and enterprise software.
- Autonomous systems: Robotaxis and other AI-enabled mobility technologies.
- AI chips: Domestic accelerator infrastructure and hardware ecosystems.
Baidu’s strategy is distinctive because it operates across much of this stack.
Its AI Cloud business is becoming particularly important. The company’s second-quarter GPU Cloud growth of 283% year over year suggests enterprise demand for AI computing remains strong, even as competition intensifies.
The larger industry question is whether vertically integrated AI companies can turn infrastructure scale into sustainable margins as model capabilities become increasingly commoditized.
