A Guardian investigation has identified a potential gap between Microsoft’s public statements regarding artificial intelligence capacity and the actual number of advanced semiconductor chips the company has deployed across its global datacenters.
Microsoft previously targeted having 1.8 million AI chips installed by the end of 2024. According to internal documents reviewed by the investigation, the company currently operates approximately 2.2 million chips—a figure described as substantially lower than what industry experts anticipated given the company’s $280 billion infrastructure investment. The discrepancy raises questions about whether newly constructed datacenters are fully operational or lack necessary equipment. This comes as Microsoft has stated plans to double its global datacenter footprint by mid-2027, with Chief Executive Satya Nadella previously announcing rapid expansion efforts.
Estimating actual artificial intelligence infrastructure progress remains challenging due to limited transparency in the semiconductor supply chain. Nvidia, which manufactures the chips essential to AI development, maintains strict confidentiality regarding sales figures and customer information. Technology companies purchasing these components similarly withhold detailed disclosures, making independent verification difficult. Researchers have attempted to estimate capacity by analyzing electricity consumption, as datacenters require substantial power resources. Microsoft’s public reports indicate it has added 5 gigawatts of datacenter capacity over two years, though calculations by academic researchers suggest the actual figure may be considerably lower.
Microsoft disputed the Guardian’s calculations but declined to specify which figures were inaccurate. The company attributed some potential discrepancies to its commercial partnership with OpenAI, suggesting certain datacenter deployments may not appear in reviewed documents. Additionally, some major projects appear incomplete—satellite imagery indicated that Microsoft’s Fairwater facility in Wisconsin, which executives claimed was becoming operational, may only be partially functional. Industry sources indicated that Microsoft’s total chip inventory has experienced minimal growth over the past year, suggesting infrastructure buildout is proceeding more slowly than annual reports might indicate.
