Microsoft Routes OpenAI Model Sales to Chinese Firms Through Singapore Data Centres

Microsoft has quietly become the primary supplier of OpenAI's GPT models to Chinese companies, routing access through data centres in Singapore to serve customers including ByteDance, Ant Group, and Meituan. The arrangement puts Singapore at the centre of a growing tension between Washington's export controls on AI technology and China's insatiable demand for frontier models.

Every AI development in Singapore adds another data point to the city-state's transformation into a global AI infrastructure hub. In this case, Singapore's data centres host OpenAI models that Chinese enterprises access over the internet — the models are not physically hosted on Chinese soil. ByteDance, Microsoft's largest AI customer globally, is on track to spend more than US$1 billion a year on Microsoft's AI and cloud services. Azure's AI revenue in China roughly tripled in the financial year ending June 2025, following approximately 400% growth the year prior.

OpenAI and Anthropic have both declined to sell their models directly into China, citing intellectual property risks — specifically model distillation — and misuse concerns. Microsoft fills this gap through its unique contractual right to resell OpenAI's GPT series. However, OpenAI has privately pressed Microsoft to do more to stop Chinese customers from distilling its models, though Bloomberg reports indicate Chinese buyers face no heightened scrutiny and synthetic data generated from the models is difficult to police. Microsoft only sells to established companies, not individual developers.

The arrangement puts Microsoft in a unique dual position: it sells American OpenAI models to Chinese enterprises while simultaneously selling Chinese DeepSeek models to Western businesses through its Copilot platform. As one former executive described it, Microsoft is "bringing those two places together" and taking the margin on both legs of the trade. The China business represents about 1.5% of Microsoft's total 2024 revenue, but the political risk is mounting as US lawmakers view China's AI push as a competitive threat.

Why it matters for Singapore: Singapore's role as the geographic intermediary for this AI traffic is not accidental — the city-state's advanced data centre infrastructure, stable regulatory environment, and openness to both US and Chinese tech companies make it the natural meeting point. But this position also exposes Singapore to geopolitical crossfire as US-China technology tensions escalate. For Singapore's AI ecosystem, the presence of both Microsoft's and OpenAI's regional operations creates spillover benefits in talent, infrastructure investment, and startup access to frontier models.
