In short: Recapped in two lines. "🇺🇸 The Race to Make America (Make) Aluminum Again" — "aluminum has become one of America's most strategic metals, vital to the military and mostly imported. Here's how Washington is now moving to fortify that supply at home" (2026-AUG-26). "The Company Keeping American Aluminum Home" — the Pulse Premium issue revealing "how the U.S. imports most of the primary aluminum its defense industry and power grid depend on. This month's recommendation offers one of the few companies still operating domestically" — captured as Century Aluminum (CENX) on the 2026-AUG-27 page.
August's aluminum pair is recapped in one sentence each, and the full argument sits on the two dated pages from earlier in the week. The short version: the U.S. barely smelts any of its own aluminum but its military and its power grid depend on the metal, so Washington is spending and taxing to rebuild domestic supply — and the 50% import tariff, applied to a metal with almost no domestic industry to protect, works as a price floor that the few surviving American smelters pocket as profit. That is why the Pulse Premium pick was a smelter, Century Aluminum.
In short: The second-order robotics material, offered as the natural follow-on question to silver: "What are the robots going to be made out of? Definitely aluminum. You're going to want them to be light." Not yet a sized position — he flags it as the class of question to keep running: "it depends really. We're going to have to keep our eyes open for other things."
The second material to fall out of the robotics thesis, and it comes from asking a deliberately childlike question: what will the robots physically be made of?
His answer is aluminium, for a mechanical reason. A robot that moves has to accelerate its own limbs; every kilogram of structure costs battery life, motor torque and stability. So designers optimise hard for weight, and aluminium is the cheap, abundant, machinable structural metal with the best strength-to-weight profile. "You're going to want them to be light."
This is earlier-stage than the silver call — he has not sized it and says so ("we're going to have to keep our eyes open for other things"). It is included because the method is the transferable part: take a projected unit volume of a new physical product, decompose it into its bill of materials, and go find whichever input is already supply-constrained.
In short: The structural case behind the pick. LME ~$3,225/t plus a US Midwest Transaction Premium near $2,000/t means an American buyer pays about $5,200/t, "roughly 60% above the world price"; the premium hit a record near $2,180/t in February, "more than triple its level just 2 years earlier." Supply: "the structural deficit is also widening" — Gulf smelter outages this spring cut an annualized 2 million tonnes and Mercuria called it "a black swan," putting this year's global deficit at "a minimum of 2 million tonnes"; LME warehouse stock "has roughly halved this year to about 250,000 tonnes, the lowest since 1990"; and China, "the source of roughly 60% of the world's aluminum, cannot lift its output past the 45-million-tonne cap the government imposed… a ceiling its smelters have now reached." Demand: aluminum "is the conductor for the high-voltage lines that carry power across the grid, and nearly every new AI data center requires vast new transmission systems"; EV production alone is projected to lift demand to 31.7Mt from 19.9Mt in 2020. U.S. supply has fallen from ~30 smelters and 4.65Mt in 1980 — then the world's largest producer — to about 680,000 tonnes, less than 2% of world supply, because smelting takes ~15 MWh per tonne ("roughly what a home uses in a year and a half") and American energy "became too costly to compete." Washington classifies aluminum a critical mineral and tariffs it under Section 232 of the Trade Expansion Act, a 1962 law letting the president restrict imports that threaten national security; the rate reached 50% in June 2025 and in April was widened "to include the full value of each shipment, metal plus fabrication and freight." "If the supply picture stays this tight, the LME price has room to rise."
Aluminum is having a genuine shortage, and for once the reason is simple arithmetic rather than speculation. The metal the whole world can freely buy sits in London Metal Exchange warehouses; that pool has roughly halved this year to about 250,000 tonnes, the smallest it has been since 1990. Outages at Gulf smelters this spring knocked out the equivalent of two million tonnes a year, which one of the world's biggest commodity traders called a "black swan." And the country that makes 60% of the world's aluminum — China — has capped itself at 45 million tonnes and has already hit that ceiling, so it cannot simply make more.
Demand, meanwhile, keeps growing for unglamorous reasons. Aluminum is what long-distance power lines are made of, and every new AI data center needs a lot of new power lines. Electric cars use far more of it than ordinary cars; one industry forecast has EV-driven demand rising from about 20 million tonnes in 2020 to nearly 32 million.
The U.S. sits on the wrong side of all this. In 1980 it had about 30 smelters and made 4.65 million tonnes — more than anyone. Today it makes about 680,000 tonnes, under 2% of world supply, because turning alumina into aluminum takes roughly 15 megawatt-hours of electricity per tonne (about what a house uses in eighteen months) and American power got too expensive versus Canada, China and the Gulf. That is why Washington now treats aluminum as a "critical mineral" and taxes imports at 50% under a 1962 national-security law, and why the shortage looks structural rather than cyclical.
In short: Her "dark horse" 2026 commodity (ranked 8/10), now turbocharged by the war: capped Chinese supply, offline European smelters, ~60% US import reliance, falling LME inventories (442,800 t), and a Hormuz energy shock — LME ~$3,400/t (+20% y/y), Midwest Premium >$1/lb. The supply gap is wider than in January.
Aluminum is hard to make more of right now. China — which makes most of the world's supply — has hit a cap it set itself, lots of European smelters that shut during the 2022 energy crisis never reopened, and the U.S. imports most of what it uses. Making aluminum takes enormous amounts of electricity, so the Iran war matters twice: it's choking off the natural gas that powers European smelters (a fifth of the world's LNG goes through the Strait of Hormuz), and it's disrupting Gulf shipping. Meanwhile demand keeps rising from EVs, the power grid, defense, and data centers. Less supply plus steady demand equals higher prices — which is why Prins, who flagged aluminum as a sleeper bet back in January, says the war just made the case much stronger. Her specific stock pick (a U.S. aluminum fabricator) is behind her paywall.
In short: Closed near $3,000/ton (+20%, highest since 2022) on physical supply constraints; power is 30-40% of cost so high prices don't spur smelting, no major new smelters short-term, and Euro 7 lightweighting could lift demand — sees prices elevated further.
Aluminum is made by melting ore with enormous amounts of electricity — power is 30-40% of the cost. So even when aluminum gets pricey, smelters can't easily make more because their power bills eat the profit, and building or even restarting a smelter takes months to years. With almost no new smelting capacity coming and carmakers using more aluminum to make lighter cars, Prins expects prices to stay high.
