Microsoft makes big AI inroads in China by selling OpenAI models
Microsoft sells artificial intelligence models to major Chinese firms including ByteDance, Tencent, and Ant Group via its Azure cloud service, according to people familiar with the matter. While partners like OpenAI and Anthropic prohibit sales to China, Microsoft continues these operations, with ByteDance alone on track to spend over $1 billion annually on Microsoft AI and cloud services.
Why is Microsoft selling AI to Chinese companies?
Microsoft maintains a presence in China to track local AI innovations and support its multinational clients. According to a person familiar with the company’s strategy, these goals outweigh the growing geopolitical rivalry between the U.S. and China.
The company’s approach differs sharply from other U.S. AI leaders. Anthropic and OpenAI don’t sell their models to Chinese firms, citing risks of intellectual property theft or harmful applications. Microsoft, however, uses a unique partnership with OpenAI that allows it to set its own sales policies for GPT models in the region.
How much are Chinese tech giants spending on Azure?
ByteDance is Microsoft’s largest AI customer in China. Sources familiar with the business say the social media giant spends more than $1 billion a year on Azure and AI models. Other significant spenders include Meituan, Ant Group, and Tencent Holdings.
Much of this investment supports these companies’ expansion efforts outside of China, according to sources. While these firms train their own domestic models, they still rely on Azure’s infrastructure for global operations.
Despite this growth, the China market remains a small slice of Microsoft’s total pie. Microsoft President Brad Smith testified before Congress that the China operation accounted for roughly 1.5% of the company’s overall revenue in 2024.
What happens when corporate growth clashes with national security?
The tension between profit and policy is evident in Microsoft’s internal communications. In a July 2025 sales meeting, then-Chief Commercial Officer Judson Althoff described the synergy between U.S. and Chinese AI development as “pretty awesome.”
Althoff told employees that Microsoft is the only company bridging the gap between the “western coast of the United States and the eastern coast of China,” where the world’s most elite AI solutions are being built, according to a reviewed transcript.
This optimism contrasts with the views of American lawmakers and tech executives who label China’s AI ambitions as an existential threat to the U.S. tech industry. Microsoft continues to market a range of AI models for software development and customer service automation, excluding only a few specific models like those from Anthropic.
