Big Tech goes deep into mining: Tesla opens lithium refinery, AWS underwrites copper extraction
Jan 14, 2026
Key Points
- Tesla built North America's first spodumene-to-lithium-hydroxide refinery in Texas, reaching production in 19 months and supplying lithium for 500,000 to 1 million EVs annually, directly challenging China's 60% global refining dominance.
- AWS underwrites Rio Tinto's new low-grade copper refining process via a 1,400 metric-ton purchase agreement, potentially unlocking 70% of global copper reserves currently uneconomical to process.
- Tech companies are vertically integrating into mining to secure critical minerals as AI infrastructure demand outpaces traditional supply chains, shifting from software-driven disruption to direct control of raw material production.
Summary
Tesla and AWS are moving upstream into raw material production to secure the critical minerals their infrastructure demands. This marks a sharp turn in how big tech companies view supply-chain risk.
Tesla built North America's first spodumene-to-lithium-hydroxide refinery in Texas, converting raw ore directly to battery-grade lithium without intermediate processing steps. The facility went from groundbreaking in May 2023 to production in 19 months, an unusually fast timeline for industrial-scale infrastructure. It can supply lithium for 500,000 to 1 million EVs per year. Tesla shipped 1.65 million vehicles last year, so replicating this facility two or three times would cover the company's total lithium needs. The process is cleaner than traditional methods, produces no hazardous waste, and yields a concrete-grade byproduct. The facility directly challenges China's 60% grip on global lithium refining.
AWS took a different approach, partnering with Rio Tinto on a 1,400 metric-ton copper purchase over four years. The deal is modest and likely insufficient for a single AWS data center, but it underwrites Rio Tinto's new process for refining low-grade copper ore. Standard copper refining becomes uneconomical when ore has low mineral density. If Rio Tinto's new methodology works, the company could unlock 70% of global copper reserves currently locked in unprocessable ore and effectively triple global copper supply. Copper prices have nearly doubled in the past two years as data center buildouts accelerate. Tens of thousands of metric tons go into a single large data center for wiring, transformers, and circuit boards.
These deals reflect a broader vertical integration into mining itself. For 15 years after Marc Andreessen's 2011 essay "Software is eating the world," tech companies disintermediated existing industries through software. Now, as AI infrastructure demands scale past software's reach, companies are terraforming the supply chain itself by acquiring mines and refineries to secure critical minerals. The AI boom has created sustained industrial-scale demand that exposed bottlenecks in chip supply, energy, and raw materials. Regulatory capture and permitting timelines move slower than data center timelines, so vertical integration is often the fastest path forward.
