CNBC · United States · A Rubaya mine landslide killed 220 and destabilised DRC tantalum supply as AI-driven capacitor demand pushed prices 15-30% higher; niobium gained a US mine and a UK anode partnership
Reports tantalum capacitor prices rising 15-30% in Q1-Q2 2026 driven by AI server build-out demand: data centre tantalum electrolytic capacitors are a high-reliability component in server power delivery systems, and AI accelerator clusters require substantially more capacitors per rack than prior-generation server architectures. Notes that the Rubaya landslide disrupted approximately 15-20% of DRC artisanal tantalum supply, coinciding with the AI demand spike.
