Is the AI build now waiting on the plug rather than the chip?

Company disclosures now point to power equipment and grid connections, not chips, as the likelier brake on the AI build, but the figure that would settle it, how long a finished data center waits for power, is not yet published.

The question

For most of the artificial intelligence (AI) build, the pace was set by silicon: whoever secured AI chips got to build. The question now is whether that has changed. Has the binding constraint, meaning the one input whose shortage sets the speed of everything else, moved from chips to electricity? That would mean the turbines, power gear and grid connections a data center needs before a single rack can be switched on.

The distinction matters because the two shortages would be relieved by different industries on different timetables. The evidence also has to come from different places: chipmakers' supply commentary on one side, equipment makers' order books and utilities' connection records on the other. This piece bears on House View variable 5, "Power, not chips, is the constraint." A chip that cannot be plugged in is inventory, not capacity.

Variable 5: The power to run AI, not the chips, now sets the pace.

What is known

On chips. NVIDIA reported second-quarter fiscal 2027 revenue of $96.2 billion, up 106% from a year earlier, of which $89.0 billion came from data centers. It guided third-quarter revenue to $108.0 billion, plus or minus 2% ⁴. Its Vera Rubin platform is in full production, with racks running at several cloud partners ⁴. Supply commitments stood at $119 billion as of April 26, 2026 ⁵. The latest release does not describe chip supply as a constraint ⁴. It does say NVIDIA secured land, power and building shells through a partnership with SB Energy in Ohio ⁴.

On power equipment. GE Vernova's gas-power equipment backlog, plus agreements reserving future production slots, rose from 100 to 116 gigawatts (GW) in the second quarter. The company expects at least 125 GW by the end of 2026 ³. Annual gas-turbine output is 20 GW in the third quarter of 2026, rising to 24 GW in 2028 and 30 GW in 2030 ³. Data-center orders in its electrification business passed $5 billion year to date, more than double the 2025 total ³. The company lists "issues with grid connectivity" among its forward-looking risks ³.

Vertiv supplies data-center power and cooling equipment. Its second-quarter net sales rose 24% to $3,274 million ⁶. It said revenue "reflected minor timing shifts" from "temporary supply chain congestion and multi-phased project execution" ⁶⁷. It guided full-year 2026 net sales to $13.8 billion to $14.2 billion ⁶. Vertiv stopped reporting quarterly orders and backlog in February; its last figure was $15.0 billion at the end of 2025 ⁸.

On the grid. The U.S. Energy Information Administration (EIA) expects electricity sales of 4,135 billion kilowatt-hours (kWh) in 2026 and 4,211 billion kWh in 2027, driven by data-center development ⁹. It notes a pause in connecting new data centers to the grid in Texas, which has not stopped the West South Central region from leading sales growth ⁹. Generation is expected to grow 2.2% to a record 4,368 billion kWh this year ¹⁰.

Vistra reported second-quarter results on Aug. 7, 2026 ¹. It cited signed power purchase agreements with Meta expected to contribute to 2027 earnings ¹. It committed up to $1.0 billion to Helix Digital Infrastructure, a vehicle with outside investors and NVIDIA. Helix is meant to invest in assets that enable AI and large-scale data-center development ¹². Vistra also reported commercial availability of 97% or better across its fleet during recent heat periods ¹.

What is missing. No company or agency filing gives interconnection queues (the waiting list of projects asking to connect to the grid), grid-connection lead times, or lead times for turbines or transformers. Vistra does not disclose how much new data-center load it has connected, or how quickly. The most important number in this debate is the one nobody publishes.

Names that bear on this

NVIDIA reported second-quarter fiscal 2027 results on Aug. 26, 2026 ⁴. This cuts toward power as the constraint. Revenue doubled and the release names no chip-supply limit. The company also said it had secured power and land for build capacity in Ohio ⁴. The next test is third-quarter fiscal 2027 results, which on the company's usual calendar fall in late November 2026, along with the quarterly filing that updates supply commitments. A shortfall against guidance attributed to supply would cut the other way.

GE Vernova reported second-quarter results on July 22, 2026, and raised its 2026 guidance ³. This cuts toward power equipment as a constraint. A 116 GW queue against 20 GW of annual output is a long line, though the company does not say how much of it is tied to AI. The next tests are third-quarter results, due on its usual calendar in late October 2026, and fourth-quarter results in January 2027, which will show whether the queue reached the 125 GW the company guided.

Vertiv reported second-quarter results on July 29, 2026 ⁶. This cuts weakly toward facility power gating deployments. The company said supply-chain congestion shifted revenue timing, but called it minor and temporary ⁶⁷. The next test is third-quarter results, due on its usual calendar in late October 2026. The questions are whether timing shifts recur and whether its guidance for growth excluding acquisitions and currency holds and deferred revenue (cash received for equipment not yet delivered) keeps rising.

Vistra reported second-quarter results on Aug. 7, 2026 ¹. On connection speed this cuts neither way. Contracts with Meta and the Helix commitment show demand for power, but the company disclosed no interconnection timing ¹. The next test is third-quarter results, due on its usual calendar in early November 2026.

The case for

The chips are arriving. NVIDIA's revenue doubled in its latest quarter, and it guided higher for the next ⁴. Its newest platform, Vera Rubin, is in full production, and racks are already running at several cloud partners ⁴. The company carried $119 billion of supply commitments as of late April ⁵, more than its entire $96.2 billion of second-quarter revenue ⁴, and its latest release does not describe chip supply as a constraint ⁴. The most telling detail is that NVIDIA secured land, power and building shells through a partnership with SB Energy in Ohio ⁴. When NVIDIA goes looking for electricity, the scarce input is no longer the chip.

The equipment queue is long. GE Vernova's gas-power backlog, together with slot-reservation agreements, rose from 100 to 116 GW in a single quarter. The company expects at least 125 GW by the end of 2026 ³. Its annual turbine output stands at 20 GW in the third quarter of 2026 and is planned to reach only 30 GW by 2030 ³. Data-center orders in its electrification business passed $5 billion year to date, more than double the 2025 total ³. The company also lists "issues with grid connectivity" among its forward-looking risks ³. Vertiv grew net sales 24% to $3,274 million. Even so, it attributed "minor timing shifts" to "temporary supply chain congestion and multi-phased project execution" ⁶⁷.

The grid is being stretched. The EIA expects electricity sales to reach 4,135 billion kWh in 2026 and 4,211 billion in 2027, driven by data-center development ⁹. Generation is expected to grow 2.2% to a record 4,368 billion kWh this year ¹⁰. The same outlook records a pause on connecting new data centers to the grid in Texas ⁹. Generators are positioning themselves accordingly. Vistra has signed power purchase agreements with Meta that are expected to contribute to 2027 earnings ¹. It has committed up to $1.0 billion to a vehicle with outside investors and NVIDIA that will invest in assets enabling AI and large-scale data-center development ¹².

Where the case is thin. This argument rests on what companies say about each side of the build, not on a direct measure. There is no primary data on interconnection queues or on lead times for grid connections, turbines or transformers. Vistra does not disclose interconnection timing ¹. Vertiv calls its congestion temporary ⁶. Still, the disclosures point one way. Chip output is not reported as a limit, while the power equipment and grid connections the chips depend on are.

The case against

The strongest case against "the grid now sets the pace" is that the disclosures show infrastructure pressure, not a demonstrated shift in the binding constraint. Evidence that power matters is not evidence that power connections determine deployment speed more than chips do.

First, NVIDIA's growth cannot establish that chip supply is sufficient. Revenue of $96.2 billion, up 106%, and $108.0 billion of next-quarter guidance measure sales and expected sales. They do not measure unmet demand or delivery times. Vera Rubin being in full production, with racks running at several cloud partners, shows deployment progress, not universal availability. The release's silence on chip constraints is weaker evidence than an explicit comparison of supply and demand would be ⁴. Likewise, $119 billion of supply commitments documents procurement obligations, not the end of production constraints ⁵.

Second, GE Vernova's figures establish a substantial equipment pipeline, but not how much AI deployment is waiting on it. The backlog plus slot reservations reached 116 GW, while annual turbine capacity rises from 20 GW toward 24 GW in 2028 and 30 GW in 2030. That supports concern about capacity pressure. But nothing breaks out how much of that pipeline is needed by AI projects that are otherwise ready. More than $5 billion of year-to-date data-center orders demonstrates demand; it does not measure delays in switching on finished sites. "Issues with grid connectivity" is a forward-looking risk, not a quantified current delay ³.

Third, Vertiv's own wording is milder than a broad grid-bottleneck thesis implies: "minor timing shifts" from "temporary supply chain congestion and multi-phased project execution." Those words support execution friction. They neither isolate grid connections nor establish persistent, industry-wide delays. Sales rose 24% to $3.274 billion regardless ⁶⁷.

Fourth, the operating evidence shows expansion proceeding. The EIA projects electricity sales of 4,135 billion kWh in 2026 and 4,211 billion in 2027, driven by data-center development. Even a Texas connection pause has not prevented West South Central from leading sales growth ⁹. Generation is projected to rise 2.2% to a record 4,368 billion kWh ¹⁰. These aggregates cannot rule out local bottlenecks, but they do challenge a blanket reading of grid paralysis. Vistra's signed Meta agreements and fleet availability of at least 97% demonstrate contracting activity and operating capability, not connection speed ¹.

The defensible rebuttal is not that chips definitely remain the bottleneck. It is that, without comparative delivery times, interconnection lead times or connected-load measurements, the constraints cannot be ranked. Power pressure is visible; grid dominance remains unproven.

What we don't know, and when

Whether the turbine queue is an AI queue. GE Vernova's third-quarter results, due in late October 2026, may break out data-center demand further. Its fourth-quarter results in January 2027 will show whether the gas-power queue reached at least 125 GW.
Whether Vertiv's congestion was temporary. Vertiv's third-quarter results in late October 2026 will show whether timing shifts recurred. Its guidance for growth excluding acquisitions and currency, and its deferred revenue, are the nearest stand-ins for the backlog it no longer reports.
Whether chips are truly unconstrained. NVIDIA's third-quarter fiscal 2027 results in late November 2026 will land against guidance of $108.0 billion, plus or minus 2% ⁴. The quarterly filing will update the $119 billion supply-commitment figure.
How fast new load is actually connected. Vistra's third-quarter results in early November 2026 are the nearest chance for a power producer to disclose connected data-center load or timing. The EIA's November 2026 Short-Term Energy Outlook will show whether the Texas pause on new data-center connections persists.
Interconnection queues and lead times. No primary source publishes them, and no release date for such a figure is scheduled. This is the gap the debate cannot close without.

What would change our mind

The House View already holds that power, not chips, is the constraint (variable 5). This piece sharpens that view rather than shifting it. On the disclosures available, the chip side reports doubling sales and no supply limit. NVIDIA itself is securing power sites ⁴. The power-equipment side reports a queue far larger than a year's output and names grid connectivity as a risk. The disclosures lean the House View's way, and the measure that would settle the question is unpublished, so nothing in the frame moves.

The tilt is not a ranking. The case against stands: no public filing measures how long a finished data center waits for electricity. The aggregate grid data show growth, not paralysis. Confidence is moderate, and the October and November results can move it. The burden of proof has shifted: the chip side must now show it is still scarce, and the power side must show its queue is what is holding deployments back.

Bears on: Power, not chips, is the constraint
What would change this: If NVIDIA's third-quarter results in late November 2026 cite chip supply as limiting shipments against its $108.0 billion guidance, while GE Vernova's orders and Vertiv's deliveries in late-October 2026 results run without power-related delay, the conclusion that power now sets the pace would not hold.
