Is The AI Trade Dead? Profits Hold, Data Center Runway Shrinks

Nvidia and AMD are selling more than ever, yet their shares fell hard on Thursday. The selloff reflects a reassessment of how long the data center buildout will last, and that question now runs through Texas grid policy, local ballot measures and the balance sheets of the companies paying for the construction. The size of the move was large. The Nasdaq Composite closed down 5.52% at 24,315, its worst day since April 2025. The S&P 500 fell 4.36%, and the Dow dropped 1,833 points. The Philadelphia Semiconductor Index plunged 12.25%, its steepest single-session loss since March 2020. Nvidia fell 9.26%, erasing roughly $450 billion of market value in one session. Micron dropped 17.46%, AMD 17.26% and Broadcom 10.43%. The CBOE Volatility Index jumped about 70% to 28.18. The sales that support these share prices have not disappeared. AMD said its data center sales more than doubled in its latest period, and the stock still fell 17.26% on the day. Share prices of chipmakers are mostly claims on years of future cash flow. When investors pay for 2029 and 2030 today, a change in their view of those years moves the price immediately, even if this year's revenue is unchanged. That is valuation compression, and it can run while current earnings stay strong. The buildout itself showed cracks this week. Bloomberg reported that Microsoft is reviewing whether to pull back from some high-risk projects and is inspecting construction sites run by neocloud companies, citing delays, permitting problems and cost burdens. Reporting also said the completion of a Texas data center operated by IREN could slip by several months because of fiber-optic installation problems. Neocloud stocks reacted sharply, with Nebius down 15%, IREN down 17% and CoreWeave down 10% on Thursday. These companies depend on signed capacity contracts turning into construction, power and revenue on schedule, so any slippage becomes idle capital that still carries interest and depreciation. Texas is the largest single reason the runway looks shorter. On August 3, Governor Greg Abbott ordered the state's grid regulator and operator to audit every data center in the interconnection queue. On September 21, he directed the environmental regulator to halt data center permits until that audit is complete. Gina Hinojosa won the governor's race on Tuesday, and she has pledged to keep the moratorium in place until the Legislature passes new laws in 2027. The queue behind that pledge is enormous. ERCOT, the state's grid operator, was tracking about 474 gigawatts of large-load requests as of June 2026, roughly 90% of them from data centers. That is more than five times Texas's record peak demand. Many of those projects may never be built. ERCOT's April 2026 report, however, showed just 5.9 gigawatts of energized large loads, with another 3.2 gigawatts approved to energize but not yet operating. The gap between requests and energized capacity is where investors have been placing their bets, and the new permit freeze shrinks the path between the two. Texas is not alone. Ballotpedia counted 41 local ballot measures on data centers in 10 states, and according to CNBC, voters sided against the projects in every measure except one in Harwood, North Dakota. An industry tracker found at least 46 data center projects in 20 states, representing more than $170 billion of announced investment, were blocked, withdrawn or stalled after community opposition between January 2024 and May 2026. Approval fights happen county by county, which means a stalled project can appear in any state where local approval is required. The election did not cause the whole decline. Chip stocks were already sliding on Wednesday over construction delays, and Qualcomm issued a disappointing forecast that added to Thursday's selling. Meta executives warned that data center construction could face disruptions after the midterms. Each headline points in the same direction, toward a slower and more uncertain buildout,
