Ruthenium, a rare platinum group metal, has nearly doubled in price over the past year to $800 an ounce, outperforming gold and silver thanks to surging demand from artificial intelligence applications. The metal’s unique hardness and conductivity make it ideal for hard disk drives used in data centers powering AI, where it enables high-density storage through ultrathin coatings. 

Unlike widely traded metals, ruthenium is sourced only as a byproduct of platinum mining, with global output limited to just 30 tons annually—a figure expected to decline further due to underinvestment. Analysts predict a supply deficit next year as demand outpaces dwindling production, intensifying competition for this obscure element. 

Despite being used in tiny quantities, ruthenium’s role in expanding cloud infrastructure is critical, with hard disk sales projected to rise 16% in 2025. 

Finsum: Unless alternative technologies emerge, ruthenium’s strategic value and price are likely to climb even higher.
