Yet the surging demand for the materials is pushing up against a supply chain gap that some warn could be difficult to bridge.\n\nDeclining ore grades, geopolitical tensions, and limited refining capacity are heightening uncertainty around critical mineral supplies, even as AI infrastructure investment accelerates worldwide.\n\nCopper is particularly at risk, facing a [projected shortfall](https://www.spglobal.com/content/dam/spglobal/global-assets/en/special-reports/copper-in-the-age-of-ai/Copper%20in%20the%20Age%20of%20AI_Full%20Report_January%202026.pdf) of 10 million metric tons by 2040 if “meaningful expansion” of the sector is not seen.\n\nBrendan Smith, co-founder and CEO of SiTration, an MIT spinout that recovers copper from mining waste, told Data Center Knowledge that data centers have become one of the more \"visible sources” of rising copper demand.\n\n“It takes about 50,000 tons of copper to build a new hyperscale data center, and we’re talking about installing many of these in the coming years,” he said.\n\nWhile data centers still account for a relatively modest share of global copper consumption, Shashank Sriram, Senior Research Analyst at Wood Mackenzie, said their buying power is reshaping the market.\n\n“Unlike traditional utilities, automotive OEMs, or construction firms operating on thin margins, hyperscalers generate revenues that allow them to absorb virtually any metal price spike,” he said. “AI isn’t creating the physical deficit on its own, but its bottomless willingness to pay is pricing everyone else out of a structurally disrupted market.”\n\nCopper, the backbone of data center infrastructure, faces growing supply challenges as demand for this essential conductor skyrockets in the tech industry.

Copper is used for power distribution, playing a key role in busbars and switchgear that deliver electricity to every rack. [Lithium](/sustainability/the-environmental-impact-of-lithium-ion-batteries-how-green-are-they-really-) underpins battery storage, while cobalt and rare earth elements show up in specialized electronics, magnets, and precision components.\n\nOf these four distinct categories, copper is the one under the [greatest near-term supply strain](/supply-chain/data-center-demand-to-exacerbate-copper-shortage), as its demand extends far beyond the data center industry and is essential for grid infrastructure, electrification, defense, and batteries.\n\nLithium, Brendan notes, faces its own supply-demand gap, albeit for different reasons.\n\n“While also growing rapidly, the value of the global lithium market today is about 10 times smaller than copper,” he said. “With lithium, we have a lot of reserves globally that are known and accessible. Copper’s problem is more structural. We’re seeing a rapid decline in supply due to a fundamental reduction in copper ore grade, which you can’t really overcome. There’s no way to magically reverse that.”\n\nFor an industry planning hundreds of new AI facilities over the coming decade, those pressures are beginning to shift attention from simply buying materials to securing long-term access to them.\n\n## A Supply Chain Under Threat\n\nAccording to Brendan, building a new greenfield copper mine in the US takes an average of 23 years from discovery to production, with permitting alone consuming roughly half that timeline. Refining capacity also remains heavily concentrated overseas, leaving manufacturers exposed to geopolitical tensions and shifting trade policies.\n\n“Only about 3% of copper that’s consumed globally is fully refined in the US today,” Brendan said. “We’re exporting a lot of raw copper ore concentrate to other countries to be refined and produced there.”\n\nRecently proposed copper tariffs have added another layer of volatility. In June, the White House [adjusted its tariff regime](https://www.federalregister.gov/documents/2025/08/05/2025-14893/adjusting-imports-of-copper-into-the-united-states) to include a 15% transitional rate for metal-intensive industrial equipment and electrical grid equipment. While refined copper was temporarily exempted, tariffs are scheduled to be phased in starting in 2027.\n\nSriram said businesses trying to get ahead of the tariffs coming into effect have “sucked vast tonnages of copper into US warehouses,” trapping nearly 2% of total global copper demand.\n\n“A massive amount of physical inventory has effectively been locked out of the global market,” he said. “Simultaneously, regulatory crackdowns on scrap trading mechanics (such as stricter enforcement on reverse invoicing) have choked off secondary feeds, forcing fabricators onto the spot market for refined cathode.”\n\nIn this climate, Greg Smith, CEO of copper manufacturer Pantheon Electric, said supply chain resilience has become just as important as manufacturing capability.\n\n“More than 50% of the US’ copper needs come from imports,” he told Data Center Knowledge. “From our perspective, the supplier with the best, most resilient and reliable supply chain wins.”\n\n## Copper as a Case Study\n\nPantheon announced in July that it had unified 21 plants across North America and Europe into a single platform, becoming, by its own account, the largest independent US maker of copper conductors and busbars. The group processes over a million pounds of copper a day for customers, including Schneider Electric, Eaton, and Prysmian Group.\n\nWhile copper is only one component of a modern data center, it is among the hardest to replace. Busbars, conductors, and electrical distribution equipment form the backbone of every facility, meaning supply disruptions can delay entire construction projects.\n\n“It’s a national security issue that must be dealt with, whether it’s friendshoring or other ways to get access to these critical minerals,” Greg said. “Even a relatively small component like a busbar can hold up delivery of a multi-million-dollar system.”\n\nFor the group, arming itself against geopolitical volatility has meant building local relationships with suppliers, recyclers, and traders in both the US and Europe.\n\nInnovation is also creating opportunities to expand supply.\n\nRather than competing for newly mined ore, SiTration is recovering copper directly from mining wastewater using an electro-extraction process that produces commercial-grade copper cathode without conventional smelting or refining.\n\n“The approach is about creating new supply outright, rather than competing for existing supply,” Brendan said.\n\nHe estimates that roughly $3.5 trillion in critical minerals remains stranded in mining waste streams worldwide, including around $500 billion in copper.\n\nIn June, the company [completed a trial with BHP](https://www.globenewswire.com/news-release/2026/06/30/3319762/0/en/MIT-Spinout-SiTration-and-BHP-Invent-collaborate-to-trial-copper-and-gold-recovery-technology-from-waste-streams.html) to recover both copper and gold from waste streams in South Australia, and has also worked with Rio Tinto in the US, with further deployments in Chile in the pipeline.\n\nBoth companies point to the same underlying strategy, even if their approaches differ: diversifying supply chains to protect future copper supply.\n\nNeither company frames this as a permanent fix to the underlying scarcity, but together they illustrate how the industry is starting to respond to the potential fallout from a supply shortage.\n\n## Future-Proofing Data Center Buildout\n\nAccording to Sriram, the immediate priority for data center developers and manufacturers is securing reliable access to materials already in circulation.\n\n“Large buyers are increasingly signing long-term offtake agreements, pre-purchasing material, and locking in supply with fabricators and refiners several years ahead of need,” he said. “This doesn't create new supply, but it does reduce exposure to shortages and price spikes.”\n\nOver the medium term, he said [recycling](/sustainability/e-waste-101-how-to-recycle-it-equipment-reduce-impact) is expected to play a growing role. Recycling copper and other critical minerals from waste streams or retired equipment could boost domestic supply faster than developing new mines, although scaling high-purity recycled material will require continued investment in processing infrastructure.\n\nDiversifying supply chains is another priority, with countries such as Canada, Australia, and Chile highlighted as potentially important partners.\n\n“In terms of what moves the needle today: long-term supply agreements, inventory strategies and selective substitution,” Sriram said. “Recycling and friendshoring can improve resilience over the medium term. Domestic refining is the most durable solution, but it remains a longer-term strategic bet.”\n\nAs hyperscalers invest billions in the next generation of AI campuses, critical minerals are becoming another pillar of data center strategy, joining power availability, cooling capacity, and network connectivity as essential considerations for future growth.", "url": "https://wpnews.pro/news/the-critical-minerals-crisis-ai-data-centers-face-supply-chain-strain", "canonical_source": "https://www.datacenterknowledge.com/supply-chain/the-critical-minerals-crisis-ai-data-centers-face-supply-chain-strain", "published_at": "2026-08-13 09:00:00+00:00", "updated_at": "2026-08-13 09:13:12.328443+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-infrastructure"], "entities": ["S&P Global", "SiTration", "MIT", "Brendan Smith", "Wood Mackenzie", "Shashank Sriram", "Data Center Knowledge"], "alternates": {"html": "https://wpnews.pro/news/the-critical-minerals-crisis-ai-data-centers-face-supply-chain-strain", "markdown": "https://wpnews.pro/news/the-critical-minerals-crisis-ai-data-centers-face-supply-chain-strain.md", "text": "https://wpnews.pro/news/the-critical-minerals-crisis-ai-data-centers-face-supply-chain-strain.txt", "jsonld": "https://wpnews.pro/news/the-critical-minerals-crisis-ai-data-centers-face-supply-chain-strain.jsonld"}}
