The Iran war and resulting disruption to shipping through the Strait of Hormuz has halted helium production in Qatar, which supplies roughly one-third of global output — and analysts are now warning this exposes an underappreciated vulnerability in the AI infrastructure build-out. Macroeconomic research firm Steno Research, led by founder Andreas Steno Larsen, has characterized the situation as a potential "bottleneck for the entire AI story," pointing to TSMC and SK Hynix as the most exposed chipmakers. Both companies reportedly source 40 to 50 percent of their helium requirements from Qatar, according to Steno Research. Helium is a critical industrial gas used in semiconductor fabrication — primarily for cooling during lithography and diffusion processes — and it cannot be easily substituted or stockpiled at scale.
Helium spot prices have surged approximately 50 percent since hostilities escalated, according to reporting by Yahoo Finance's Ines Ferré. Phil Kornbluth of Kornbluth Helium Consulting, a specialist helium market consultancy, has been cited as a key expert voice on the structural vulnerability this exposes. Unlike previous supply disruptions, this crisis arrives with virtually no government buffer in place. The US Bureau of Land Management completed the sale of the entire Federal Helium System — including the Bush Dome Reservoir near Amarillo, Texas, which once held approximately 34 billion cubic feet of crude helium — to Messer LLC in June 2024 for roughly $21 million, a price Kornbluth described as far below market value. That reserve, which at its peak represented half of annual global production, was effectively the world's only strategic helium buffer, and its liquidation under the 1996 Helium Privatization Act leaves no government backstop for the current disruption.
For investors, the near-term beneficiaries appear to be US domestic industrial gas suppliers insulated from Middle East risk. JPMorgan upgraded Linde and Wells Fargo upgraded Air Products and Chemicals, as capital rotates toward producers positioned to capture premium pricing on constrained helium supply. Longer-term, ExxonMobil's LaBarge facility in Wyoming — producing around 20 percent of global helium supply — and Blue Spruce Operating's $737 million Dry Piney project in Wyoming, approved in December 2025 and expected to come online by 2028, represent the primary domestic scale-up pathways. Neither, however, is capable of bridging a near-term Qatari outage of any duration. For AI infrastructure timelines that depend on TSMC and SK Hynix running fabs at near-maximum capacity utilization to meet accelerator and HBM memory demand, the helium situation is a supply chain risk that was largely invisible until hostilities forced it into focus.
