SANTA CLARA, CALIFORNIA — The war in Iran has created an unexpected chokepoint for artificial intelligence infrastructure: helium. Gas suppliers are racing to reassure major chip manufacturers that production will continue uninterrupted as roughly one-third of global helium supply remains offline due to the conflict.
Helium plays an essential role in semiconductor manufacturing, serving as a cooling agent during the fabrication of advanced chips. The element's unique properties — remaining liquid at temperatures near absolute zero — make it irreplaceable in processes that produce the nanometer-scale transistors powering modern AI accelerators.
The shortage arrives at a critical moment for the AI industry. Demand for specialized chips from NVIDIA, AMD, and emerging competitors has surged 340% year-over-year, driven by enterprise adoption of large language models and autonomous systems. Any disruption to chip production could cascade through supply chains already strained by geopolitical tensions.
Industry sources indicate gas suppliers are drawing down strategic reserves and redirecting supplies from less critical applications, including medical imaging and scientific research. Spot prices for helium have increased 180% since January, though long-term contracts with major chipmakers have largely held steady.
The situation highlights infrastructure vulnerabilities in AI development that extend beyond compute and power. Iran's helium reserves, among the world's largest, have been effectively removed from global markets. Alternative sources in Qatar, Russia, and the United States are operating at capacity, with no significant new production expected before 2028.
Chip manufacturers have declined to comment on their helium inventories, citing competitive sensitivity. However, industry analysts note that fabrication facilities typically maintain 90-day supplies, suggesting the current disruption remains manageable if resolved within that window. Beyond that threshold, production delays become probable.
