Meta Platforms is becoming one of Microsoft’s largest customers for artificial intelligence services, using Microsoft Azure to access AI models, Bloomberg reports. The companies’ spending amounts are described as “hundreds of millions of dollars” per year, placing Meta among Microsoft’s biggest AI-related cloud customers.

The reporting links Meta’s AI usage to very large-scale compute activity, including an estimate that Meta runs “trillions of tokens” each week through Azure, according to a person familiar with the matter. Across outlets, the shared focus is on how demand for AI infrastructure and model access remains heavily concentrated among large technology companies.

Bloomberg also notes that Meta and Microsoft’s close business relationship revives discussion in the industry about potential circularity in AI partnerships—where major players both provide and consume AI services—though both companies decline to comment in the coverage summarized here. The Next Web’s account largely reiterates the reported spending and usage scale, without adding new details beyond the Bloomberg sourcing.
