The Trillion-Dollar Hallucination

The market spent last Tuesday doing what it does best: repricing a fact everyone already knew as if it had just discovered gravity.

Micron Technology crossed $1 trillion in market capitalisation on May 26, after shares surged 19% in a single session — becoming only the second memory company in history to reach that milestone after Samsung. The catalyst was a UBS upgrade so aggressive it bordered on self-parody. Analyst Timothy Arcuri tripled his price target from $535 to $1,625 per share — now the highest on Wall Street — arguing the company deserves a valuation multiple on par with elite AI infrastructure plays.

Stop and sit with that for a moment. A memory chip company. A business that posted consecutive quarterly losses in 2023 because there was too much of the same product lying around in warehouses. Now worth more than JPMorgan Chase. Now treated by the market as an irreplaceable monopoly on the future.

The reasoning isn't entirely wrong, which is what makes it dangerous. High-bandwidth memory chips cannot be substituted with standard DRAM. A Nvidia H100 uses six HBM2e stacks; the B200 uses eight HBM3e stacks. The memory is co-packaged with the GPU on a multi-chip module. The supply chain for producing it runs through three companies. Micron is one of those three. When the whole planet is in a race to build AI data centres and there are only three factories on earth making the one component every GPU needs, yes, fine — that's pricing power. That's a moat.

But here's the thing about moats: they have to remain moats. Memory chips are a notoriously cyclical business. Micron has been through brutal downturns before, most recently in 2023 when oversupply cratered prices and the company posted consecutive quarterly losses. The current supply shortage could reverse if AI spending slows or if Samsung and SK Hynix ramp HBM production faster than expected. The UBS upgrade arrived on the back of Micron disclosing that its HBM capacity is fully sold out through the end of 2026 under long-term agreements, with next-generation HBM4 production already ramping for 2027 delivery. Sold-out capacity is a beautiful thing. Right up until it isn't.

What the market is doing right now is extrapolating a supply constraint that exists today forward into eternity. It is pricing Micron as if the HBM shortage will persist long enough to justify a valuation that, per Gurufocus, sits at roughly 153% above its assessed intrinsic value — a number that doesn't so much wave a red flag as set fire to one. Meanwhile, insiders sold $54 million worth of shares in the three months leading up to the surge. The people who know the building best were quietly using the exit.

None of this means Micron is wrong. It means the market is doing what it always does in the middle of a cycle: confusing duration with permanence.

The Strait of Hormuz Hope Trade

Across the rest of the tape, the dominant narrative of the past week has been the slow, grinding hope that the Strait of Hormuz might eventually function as a strait again.

Global oil prices have tumbled roughly 20% from their 2026 highs as investors grew increasingly optimistic on prospects for a long-lasting ceasefire deal between the US and Iran, which would unlock shipping through the Hormuz Strait. Brent finished last week below $93. WTI fell 9.2% — its biggest weekly loss since early April. The S&P 500, meanwhile, closed Thursday at a record high of 7,563.63, apparently satisfied that peace is imminent and that lower energy costs will flow cleanly into corporate margins.

The optimism is, at best, provisional. Crude loadings inside the Gulf remain extremely low, and even if the Strait of Hormuz is opened, the opening will only be partial, given significant damage to infrastructure, refineries and pipelines across the Gulf, coupled with ongoing security challenges for tanker traffic and depleted inventories. There are also mines. Iran has been explicit about this. The strait doesn't reopen because two governments sign a memo; it reopens when someone physically clears the water. These are different timescales.

Markets are trading the headline, not the logistics. They have been doing this for the better part of two months now: selling off when ceasefire talks collapse, ripping higher when they resume, oscillating between $88 and $112 WTI like a fever chart. The front-month Brent contract finished May at its lowest level in more than five weeks. The relief is real. So is the fragility.

Canada's Uncomfortable Chair

One country that cannot afford further fragility: Canada. Real GDP contracted for two consecutive quarters, placing the country into a technical recession and pushing Canadian yields lower. The two-year government bond yield fell to 2.77%. The Bank of Canada now sits in an increasingly uncomfortable chair — a domestic economy slowing fast enough to warrant rate cuts, inflation that has been running hot because of energy costs, and a currency that was already under pressure before the Middle East conflict added its own particular stress.

The loonie's situation is a neat encapsulation of the entire macro environment right now: structurally torn between two forces that want different things from you simultaneously. Weaken to support the economy; hold to defend inflation credibility. There is no clean answer. There is only the choice of which problem you'd rather have more of.

The Complacency Checklist

Zoom out and what you see is a market that has, over the past few weeks, talked itself into a fairly benign scenario: AI spending is structural and infinite, the Middle East is basically resolved, the Fed doesn't need to do anything dramatic, and the S&P 500 at 7,563 reflects appropriate risk pricing. Each of those beliefs might be defensible on its own. Together, they form something that rhymes with complacency.

The difference between May 2025 and May 2026 is not the facts. It is the market's willingness to price them. Micron's capacity constraints were disclosed a year ago. The Hormuz disruption was a known geopolitical risk. Canada's stagflationary squeeze was visible in the data. None of this is new. What changes is sentiment, and sentiment has a way of reversing faster than the fundamentals that supposedly justify it.

The trillion-dollar club has a new member. Enjoy it while the supply shortage holds.
