An Edison disclosure on May 25 put the QatarEnergy Ras Laffan force majeure horizon at mid-August, three months longer than the May 4 extension that ran to mid-June. The headline is LNG. The story underneath is helium. Roughly 30 percent of the world’s traded supply is recovered as a byproduct of the same Qatari liquefaction trains that took missile damage on March 18 and 19. Trains 4 and 6, representing 12.8 million metric tons a year of LNG capacity (about 17 percent of Qatar’s total), are still offline. QatarEnergy’s CEO said in March repairs will take three to five years.

The chip stack is the casualty. Helium cools the lasers in EUV lithography and serves as a cover gas in the deposition chambers that build the metal layers inside every AI accelerator. Nitrogen and argon do not substitute. TSMC, Samsung, and SK Hynix began rationing supply through April, as Asian fab stockpiles, typically two to three months of cover, ran out into May. Spot prices roughly doubled from the pre-crisis $500 per thousand cubic feet to a $1,000 to $1,200 band. Linde, which holds roughly six months of demand in storage, was upgraded by JPMorgan specifically on the squeeze.

What’s happening

Brazil angle

Brazil is a net helium importer. Commercial production is not expected within the near-term forecast horizon (Market Research Future, Brazil helium report). The geology is not the problem. The Solimões and Parnaíba basins both produce nitrogen-rich natural gas, the kind of feedstock that, with the right cryogenic separation train, yields commercial helium. Eneva, which bought the Juruá field from Petrobras in 2020, is rehabilitating four wells through 2026 in the Solimões under a remote-generation thermoelectric thesis (CPG Click Petróleo e Gás, 2026). Helium is not in the project scope. The ANP’s published 2025 to 2026 regulatory agenda does not flag helium separation as a priority.

The asymmetric opportunity is obvious to anyone who has read the gas analysis on Solimões nitrogen content. Brazil produces nothing today. With a separation plant tied to existing gas infrastructure in the Solimões or Parnaíba, the country could move from importer to regional supplier in a window where Qatari supply is out and Russian (Amur GPP) supply remains sanctions-risked. Petrobras and Eneva are not pursuing it. BNDES is deploying the R$1 billion Vale critical minerals fund and a new R$15 billion credit line, both of which sit on rare earths, niobium, and lithium. Helium has not been named. The capital is moving past Brazil on this one.

US angle

Six new US helium operations came online in 2025: three in New Mexico, one each in Colorado, Kansas, and Montana (USGS Mineral Commodity Summaries 2026). Pulsar Helium’s Topaz project in Minnesota is the highest-grade pure-play, with concentrations of up to 14.5 percent (industry norm is 0.3 to 1 percent), running a 10-well drilling program toward a mid-2026 development decision (Crux Investor, 2026).

The policy gap is the tell. Helium was analyzed by USGS for the 2025 Critical Minerals List, finalized in November 2025, and not included (Federal Register, November 2025). That decision predates the Qatar strikes. It also predates the EUV-helium dependency curve hyperscalers are now flagging in capex models. A redesignation under DPA Title III, or inclusion in the next critical minerals revision, would unlock LPO loan guarantees and 45X-style production credits for domestic separation. The Peterson Institute called for reconstituting the Federal Helium Reserve in April (PIIE, 2026). The Federal Helium System assets at Cliffside were sold in two lots in January 2024 and the BLM lease ended that summer. There is no national stockpile to draw down.

China angle

China imported over 4,924 tonnes of helium in 2025 and meets only about 5 percent of domestic demand from local production. State media puts the production target at 3 million cubic meters annually by end-2026, which would raise domestic self-sufficiency to roughly 12 percent (Asia Isotope International, 2026). Chinese suppliers are reportedly pursuing ASML-certified ultra-pure helium qualification, which would allow domestic gas to ship into the Shanghai logic foundry buildout without depending on Qatari or Russian volumes (TrendForce, March 16). Even if the qualification lands, the domestic gap is structural. China is buying every kilogram of Russian Amur helium it can move and will be a net importer through the decade.

What it means

The Tantalum AI Materials sub-index (TAI-M) tracks helium via the USGS quarterly reference, which lags spot by months. A naive read of TAI-M misses the helium shock entirely until USGS prints the Q2 reference. SOV50 is the more honest read: a single-country concentration above 30 percent that just took a multi-year supply hit is exactly what the index is designed to flag, and helium is not currently in the basket. That is a gap on the desk’s part and worth a review at the next index reconstitution.

For builders and policymakers, the binding constraint on the next 18 months of AI chip output is not lithography tool delivery from ASML. It is the gas that runs through the tool. That changes the procurement question for every hyperscaler, and it puts the countries with cryogenic separation capacity (US, Algeria, Russia, Canada, Australia) in a stronger position than the ones with gas reserves but no plant.
