Pre-Market Brief | Friday, August 21, 2026

The binding constraint on the AI buildout is no longer chips. It is electricity.
Morgan Stanley says more than half the power US data centers need by 2028 has nothing behind it yet.
Where Futures Sit
Nasdaq 100 futures up 0.4 percent. S&P 500 futures up 0.3 percent. Dow futures up about 160 points.
Thursday was ugly. The S&P 500 closed at 7,641.16, down 0.87 percent.
The Nasdaq lost 1.00 percent, the Dow 1.32 percent, the Russell 2000 1.34 percent.
Macro Pulse
Flash US PMI at 9:45 AM ET. July's composite was 54.5.
The 10-year sits at 4.71 percent, the 30-year at 5.25 percent. Treasury doubled its buybacks of long-dated debt this week and the relief lasted a day.
Brent near $93 with Hormuz unresolved. Fed Chair Warsh speaks at Jackson Hole next week.
Stock Highlight: GEV
Morgan Stanley priced the bottleneck yesterday. US data centers need roughly 68 gigawatts of power by 2028, and about 38 of those gigawatts do not exist in any plan, on any grid, anywhere. That is more than half the requirement with nothing behind it.
A chip shortage gets solved in eighteen months. A power shortage takes a decade, because you cannot fast-track a turbine, a substation, or a transmission right-of-way.
Picture a new subdivision going up. The builders get the headlines. Nothing gets occupied until the utility runs the line and sets the transformer.
GE Vernova makes the turbines. Its Gas Power backlog hit 116 gigawatts in Q2, and data center orders in its Electrification unit topped $5 billion in the first half, more than double all of 2025.
The honest other side: a backlog is not earnings. At 5.25 percent on the long bond, every dollar of it gets discounted harder than it did in January.
Tickers To Watch
GEV, ETN, VRT: The power layer. Eaton's Q2 data center orders rose about 85 percent.
NVDA: Reports Wednesday. Held near $220 while the group fell. China eased H200 curbs.
AMD, INTC, AVGO: Each down 4 to 5 percent Wednesday. The PHLX Semiconductor Index posted its steepest three-day slide since March.
WMT: Down 9.15 percent Thursday. Comps grew 2.6 percent against the 3.8 percent expected.
ROST, DE: Up about 8 and 7 percent premarket on beats and raised full-year guidance.
Bottom Line
The market spent this week arguing about chip multiples. The thing that actually decides how much AI gets built is a power line nobody has broken ground on.
That gap is why the shovel makers and the megacaps are starting to trade differently. One group sells into a signed backlog. The other spends its own cash flow to buy.
For anyone drawing on a portfolio within ten years, the risk this morning is not missing the AI trade. It is paying a growth multiple for a backlog discounted at 5.25 percent.
Wednesday night answers part of that. Jackson Hole answers the rest.
