Hyperscale AI data center uses 150–300 tonnes copper

Derrick Dao said in a May 23 post on X that a single hyperscale AI data center can use 150 to 300 tonnes of copper, or roughly three to five times a conventional facility. The post also cited a 520,000-tonne structural copper deficit and used a copper price of about $6.30 per pound in its market analysis. Public data reviewed for this story supports the broader direction of the claim — that AI data centers are becoming a meaningful source of copper demand — but available source material shows wide variation in per-site copper estimates and points to power delivery, not server racks alone, as the main constraint. ### Where does the copper actually go inside an AI data center? BHP said on January 20, 2025 that data centers use copper in power networks, circuit boards and cooling systems. The miner cited a study of Microsoft’s $500 million Chicago data center that found 2,177 tonnes of copper use, equal to 27 tonnes per megawatt of applied power. (google.com) Copper’s job is mostly electrical. It is used in cabling, busbars, transformers, switchgear, backup power equipment and connections between the site and the grid, with additional use in heat-transfer equipment and electronics, according to BHP and S&P Global. S&P Global said in its January 8, 2026 report that copper demand is being driven by electrification, digitalization and technologies including AI and data centers. (bhp.com) ### Why do estimates for one site range so much? The 150-to-300-tonne figure in the X post appears to describe a narrower slice of copper use than some industry studies. BHP’s Chicago example is in the low-thousands of tonnes, while some market commentary has used much larger numbers for full hyperscale campuses. That gap likely reflects differences in what is counted — building-only copper, electrical equipment, off-site transmission upgrades, or an entire campus rather than one hall — though that is an inference from the source material rather than a published reconciliation. (bhp.com) S&P Global said its 2026 copper study draws on a data center database covering more than 14,000 facilities in over 135 countries. That points to a market where site design, power density and grid connection scope can materially change copper intensity from one project to another. ### Is AI demand large enough to move the copper market? (bhp.com) The International Energy Agency said in a report published May 21, 2025 that total global copper demand rises from 26.7 million tonnes in 2024 to 31.3 million tonnes in 2030 in its Announced Pledges Scenario, with grids and other clean technologies accounting for a growing share. The IEA report is not an AI-only forecast, but it shows copper demand already rising across multiple sectors competing for the same metal. (spglobal.com) J.P. Morgan and the International Copper Study Group have published differing deficit forecasts for 2026, and market commentary has tied some of that tightening to AI infrastructure demand. The 520,000-tonne deficit number in the social post is more aggressive than the deficit figures surfaced in broad public searches, which included 150,000 tonnes from ICSG and 330,000 tonnes from J.P. Morgan-based commentary. (iea.org) ### Why are power connections part of the copper story? Bloom Energy said in its January 2026 Data Center Power Report that “power availability” has become a defining boundary on data center growth. The company said interconnection timelines are widening, capital is concentrating in power-advantaged regions, and one in five campuses is expected to exceed gigawatt scale by 2030. (miningvisuals.com) That matters for copper because the bottleneck sits upstream of the server room. Grid links, substations, transformers and on-site generation all require copper-intensive equipment, and delays in those systems can slow an AI project even when chips and land are available, according to Bloom Energy and BHP. ### What does the current copper price show? (bloomenergy.com) COMEX copper for May 2026 was quoted around $6.30 per pound in market data around May 21, close to the price used in the X thread. Other market data showed copper closing around $6.35 to $6.38 per pound on May 22 after a sharp run-up this year. S&P Global’s January 2026 report and Bloom Energy’s 2026 survey are the next useful checkpoints for tracking whether AI-related copper demand and grid delays continue to tighten project timelines.
