Microsoft strengthens AI foothold in China with OpenAI model sales
Microsoft Corp. has established a substantial enterprise in providing AI models to Chinese firms, even amid the escalating competition between the United States and China regarding artificial intelligence. Social media and AI powerhouse ByteDance Ltd. has emerged as Microsoft’s foremost AI client in recent years, predominantly leveraging OpenAI models, as reported by sources. The Beijing-based company is poised to allocate over $1 billion annually towards Microsoft AI and cloud services, according to individuals. Other Chinese tech firms, including Ant Group Co., Meituan, and Tencent Holdings Ltd., are notable investors in AI models through Microsoft’s Azure cloud service, according to sources with knowledge of the industry. Microsoft considers maintaining a presence in China advantageous for staying abreast of local innovations and catering to the needs of multinational customers, as per insights from an individual acquainted with the company’s perspective. The China operation remains relatively small, contributing merely approximately 1.5 percent to overall revenue in 2024, as stated by President Brad Smith during congressional testimony. However, the company’s operations in China have sparked controversy in certain circles. American tech executives and lawmakers have characterised China’s advancements in AI as a potentially existential threat to the US industry.
Citing concerns regarding intellectual property theft and potential harmful applications, Anthropic PBC and OpenAI refrain from selling their models to companies based in China. Microsoft and OpenAI refrained from providing any comments. Behind the scenes, Microsoft has exhibited a contrasting sense of confidence — quite the opposite. In a July 2025 internal sales meeting, Chief Commercial Officer Judson Althoff highlighted Microsoft’s swift expansion in AI within China, as indicated. “The world’s most elite AI solutions are being built on the western coast of the United States and the eastern coast of China,” Althoff stated. The one company bridging those two locations is Microsoft. It is quite impressive. Azure’s AI revenue was expanding at a more rapid pace in China compared to other sales territories, Althoff informed employees — approximately tripling in the fiscal year that concluded in June 2025 and experiencing a remarkable 400 percent increase the prior year. Through a distinctive collaboration with OpenAI, Microsoft establishes its own regulations regarding the sale of models such as the GPT series in China. It also provides a range of other AI models, omitting certain options such as those from Anthropic. Microsoft offers these products to customers for various applications, including software development and the automation of customer service.
ByteDance, Meituan, and Tencent did not respond to enquiries for comment, leaving the specifics of their utilisation of the models purchased on Azure ambiguous. According to individuals familiar with their operations, a significant portion of their expenditures is directed towards facilitating expansion beyond China. The Chinese companies referenced in this narrative all develop their own AI models. ByteDance offers a widely used AI chatbot in China called Doubao. Microsoft teams located in Asia oversee ByteDance as a client, according to sources. An Ant Group spokesperson stated that the company independently develops its own AI models and that its core products do not depend on external models. At times, OpenAI has expressed concerns to Microsoft regarding the adequacy of its efforts to prevent Chinese companies from replicating its models, a process referred to as “distillation,” according to sources familiar with the discussions. It remains ambiguous which specific policy alterations, if any, OpenAI has pursued from Microsoft. Microsoft utilises automated monitoring to assist in preventing customers from leveraging AI models to create competing products.
In China, the company restricts the sale of AI models to established enterprises rather than individual developers, adhering to local regulatory frameworks, as reported by an informed source. Customers in China are not under any increased scrutiny by Microsoft regarding their utilisation of AI models, according to sources familiar with the matter. Moreover, it is infeasible to entirely inhibit companies from leveraging OpenAI models to assist in the development of their own, which includes the generation of synthetic data for training objectives. Microsoft needs local partners to sell products in China. It operates several data center regions within the nation, in proximity to Beijing and Shanghai. However, under its agreements with OpenAI, Microsoft does not host models in server farms located in China due to concerns that the intellectual property could be compromised, according to sources familiar with the arrangement. Instead, customers must access the models via the internet from facilities located in other countries, such as Singapore.
