Eleven-Fold and the Question Nobody Is Modeling
The Cost Curve the Chip Rally Left Out
The wires this week led with chip stocks. Marvell surged. Hewlett Packard Enterprise beat. The S&P 500 crossed 7,600 for the first time. Behind that tape, the physical infrastructure required to run the AI buildout is repricing at a pace the equity market has not absorbed. PJM’s capacity auction results tell the story in a single number: $329 per megawatt-day, up from $29 two years ago. That is an eleven-fold increase in the cost of securing future power supply, driven almost entirely by data centers filing interconnection requests the grid was never designed to process at this volume.
The chip market is pricing AI demand. The power market is pricing AI constraint. They have not met in the middle.
The Shortfall That Is Not a Model. It Is a Deficit.
In this tape, PJM’s 2027–2028 capacity auction fell 6,623 megawatts short of its reliability target. That target exists for a reason: it models the amount of generation capacity the grid needs to prevent more than one unexpected outage every ten years. The shortfall is not a planning abstraction. It is a physical deficit in generation that has not been built, permitted, or contracted. And the demand side is not waiting. PJM’s load forecast jumped 5,400 megawatts in a single year, almost entirely from data centers.
Our view: when the largest grid operator in the country tells you it cannot secure enough generation to meet its own standard, and the equity market prices the demand driving that shortfall as a growth story, the tape is split. One side will reprice.
The Federal Signal Hiding in Plain Sight
Worth watching: the DOE’s Agora platform, launched this week, is the federal government’s admission that the grid cannot model AI loads with existing tools. The platform simulates volatile, high-density power demands from hyperscale campuses because real-world interconnection data is too unstable to plan around. This is not a research project. It is an emergency diagnostic.
The $700 billion in industry-wide AI capex announced this year assumes the megawatts exist. PJM’s auction says they do not. The gap between capex ambition and delivered power is the trade the equity market has not priced.
The Two Numbers That Settle This by Friday
Broadcom’s earnings, reported after Wednesday’s close, showed $10.8 billion in AI semiconductor revenue. That number confirms the demand side of the equation. Watch the stock’s reaction Thursday: if the market buys the demand story without pricing the infrastructure constraint, the AI trade is still running on the assumption that power will follow capital. Watch utility names tied to PJM’s footprint: if they begin to outperform chip stocks, the market is starting to price the bottleneck.
And watch Friday’s jobs data: if the 10-year pushes above 4.55 percent, the cost of financing every megawatt of new generation rises in real time, widening the gap between what AI needs and what the grid can deliver.
