HYDERABAD, India, July 7 — The copper thieves arrive before dawn. At Microsoft’s sprawling AI data center construction sites in Virginia and Arizona, workers have reported waking to the telltale signs of stripped wiring, severed cables, and the gaping holes where spools of copper once sat. It is a shadow industry feeding on the most ambitious infrastructure build in modern corporate history.
Satya Nadella, the man who has transformed Microsoft from a software giant into a global artificial intelligence powerhouse, now faces a problem that sounds more like a heist film than a quarterly earnings call: securing the physical backbone of the AI revolution. Since taking the CEO seat in February 2014, Nadella has steered Microsoft into a dominant position in artificial intelligence.
The company’s market capitalization surpassed $3 trillion in 2024, a milestone few thought possible a decade earlier. But that valuation rests on a foundation of concrete, steel, and copper — thousands of miles of copper wiring that connect the servers powering the AI models reshaping industries. In January 2025, Nadella announced an $80 billion investment in AI data centers for fiscal year 2025.
It is the largest such commitment by any company, a bet that dwarfs even the most ambitious tech spending plans. The scale of the build-out has turned construction sites into magnets for thieves.
Copper theft has emerged as a persistent operational headache. The metal, which has surged in value on global markets, is easy to strip and sell. Microsoft’s sites in Virginia — home to the world’s largest concentration of data centers — and Arizona have both reported incidents.
Workers describe the aftermath: empty cable trays, cut security fences, the eerie quiet of a site where power has been rerouted around the damage. Nadella has emphasized the need for security. Microsoft has responded with a layered defense: AI-powered surveillance systems that can detect suspicious movement patterns, combined with private security firms patrolling the perimeters.
The irony is not lost on engineers — they are using the very technology the data centers are built to run. Born in 1967 in Hyderabad, India, Nadella holds a bachelor’s degree in electrical engineering from Manipal Institute of Technology and an MBA from the University of Chicago.
His path from student in southern India to the helm of one of the world’s most valuable companies has been a central narrative of his tenure. He has become one of the most visible executives in the AI era, testifying before the U.S. Congress on regulation and positioning Microsoft as a voice for responsible development. The security challenge at the construction sites is a reminder that the AI boom is not just a software story.
It is a physical one, built on raw materials and labor, vulnerable to the same old-world problems that have plagued industrial projects for generations. By nightfall, the sites are quieter.
Guards patrol. Cameras scan. But the thieves are patient.
They study the patterns, wait for the gaps. For Microsoft, the race to build the future of AI means also racing to protect it.
