Microsoft’s artificial intelligence infrastructure buildout appears to be progressing more slowly than public statements suggest, according to an investigation into the company’s chip deployment numbers. The technology company has reportedly installed 2.2 million advanced AI chips in its datacentres worldwide, substantially below the expectations some industry analysts held. This discrepancy emerged as Microsoft undertakes a $280 billion expansion of its computational infrastructure to support AI development.
The company had previously announced plans to have 1.8 million AI chips operational by the end of 2024. Nearly two years later, the 2.2 million figure represents growth but remains modest relative to the scale of Microsoft’s stated investments and ambitions. The gap between announced capacity and actual deployed chips highlights challenges in the global competition for advanced semiconductors, which are primarily manufactured by Nvidia and essential for training large AI models. Experts note that the chip supply chain operates with significant opacity, as Nvidia and major technology companies rarely disclose detailed information about chip production and distribution volumes.
Microsoft claims to have added approximately 5 gigawatts of datacentre capacity over the past two years as part of its AI infrastructure push. However, academic researchers analyzing the company’s sustainability reports suggest actual operational capacity may be considerably lower. One analysis estimated Microsoft’s AI capacity at closer to 1.2 gigawatts based on electricity usage data. The variance between different measurement approaches underscores the difficulty in independently verifying datacentre operational status and chip installation rates.
Additional complications include delays in bringing announced capacity online. Some major Microsoft projects, including a significant facility in Wisconsin, appear only partially operational despite announcements suggesting readiness. The company disputed the Guardian’s calculations but provided no specific corrections. Sources within Microsoft indicated that total AI chip numbers have remained largely unchanged over the past year, suggesting infrastructure expansion has slowed significantly from the pace implied by capital expenditure announcements.
