#AIBoomDrivesTungstenShortage The artificial intelligence boom has exposed a quiet but increasingly critical bottleneck in the global technology supply chain: tungsten. While attention remains fixed on GPUs, high-bandwidth memory, and power infrastructure, the metal that enables microscopic wiring inside advanced chips is facing acute shortages. Tungsten hexafluoride, the gas used in chemical vapor deposition to form interconnects in high-performance semiconductors, has become a strategic pressure point. Without reliable supplies of this compound, production of the memory and logic chips that power AI systems faces real constraints.

China controls roughly 80 percent of global tungsten production. Beginning in 2025, Beijing tightened export controls, eventually limiting authorized exporters to a small number of firms for the 2026-2027 period. The impact has been felt most sharply downstream. Two major Japanese producers of tungsten hexafluoride, which together accounted for approximately 25 percent of global capacity, halted operations in early July 2026 after exhausting available high-purity feedstock. Samsung and SK Hynix have been forced to accelerate the qualification of alternative suppliers, a process that normally takes 18 months or longer. Market participants are already discussing price increases of 70 to 90 percent for the specialized gas in the second half of the year.

Price signals confirm the severity of the squeeze. Benchmark ammonium paratungstate prices in Western markets have remained elevated above 3,000 dollars per metric ton unit, reflecting a multi-fold increase from levels seen in prior years. Some assessments place the surge as high as sixfold or more during peak periods in 2026. Global tungsten demand is projected to rise from roughly 143,000 tonnes in 2025 toward 210,000 tonnes by 2035, driven by the simultaneous expansion of AI infrastructure, defense applications, and industrial uses. New mine supply cannot respond quickly. Developing a tungsten project from exploration to production typically requires many years of permitting, construction, and processing investment.

The semiconductor industry is exploring partial substitutions. Certain next-generation NAND designs are shifting from tungsten to molybdenum for word lines as layer counts increase, but this transition is gradual and does not eliminate near-term dependence on tungsten for other critical process steps. The result is a structural rather than cyclical shortage. AI-driven demand is capital-intensive and long-duration, while supply remains highly concentrated and subject to geopolitical restrictions.

My personal assessment is that this development underscores a broader vulnerability in the technology stack. Markets have spent years focusing on the most visible constraints—chip design, advanced packaging, and electricity—while underappreciating the specialized materials that make those chips possible. Tungsten is not unique in this regard, but the combination of extreme concentration of supply, rapid demand growth from AI, and export restrictions has made the pressure unusually acute. Companies and governments that treat the issue as temporary risk underestimating both the duration of the shortage and the strategic implications for manufacturing independence.

For investors and industry participants, the situation highlights the importance of monitoring upstream materials alongside the more familiar semiconductor names. Price volatility is likely to persist as buyers compete for limited high-purity feedstock and as alternative supply chains slowly develop. The AI boom has already transformed demand for compute, memory, and energy. It is now revealing how dependent that entire edifice remains on a handful of critical metals whose production is far less elastic than the capital markets that fund the buildout.
