David Sacks Warns the AI Data Center Pipeline Could Close by 2028

David Sacks, the venture capitalist and All-In podcast host, said on the November 7 episode that the AI data center construction pipeline could be "closed or significantly reduced" by 2028. His reasoning is not demand or capital. It is permitting, and the warning lands on an AI hardware supply chain whose growth projections all assume the building boom continues.

"Nobody can make a $50 billion investment in conditions of uncertainty. I think by 2028 the pipeline will be closed or significantly reduced," Sacks said on the episode, which covered the midterm elections, the recent AI selloff, and what the hosts described as a data center freeze.

The stakes are measurable. NVIDIA reported Data Center revenue of $89.02 billion, up 117%, in its latest earnings release filed with the SEC. Broadcom has told investors it expects fiscal 2028 AI semiconductor revenue of $230 billion. Both numbers sit inside the exact window in which Sacks predicts the pipeline could shut.

What does Sacks's argument actually rest on?

Permitting. Sacks said the biggest danger for developers is breaking ground on a site and then, halfway through construction, getting "enjoined" (blocked by a court order) or stopped by a worker strike or a community group. A half-built data center is a stranded cost, and the risk of that outcome is what he argues freezes capital before it commits.

Sacks added that governors in the largest data center states are "basically indicating that they favor a moratorium" until certain conditions are met. If those moratoriums become law, new projects stop at the permitting desk. Existing projects face the injunction risk he described.

The distinction matters for investors. A demand slowdown hits every supplier equally. A permitting freeze hits companies that depend on new construction first, while potentially helping companies that already own permitted, powered capacity.

Why does a permitting freeze reach every supplier?

A data center needs land, power, and a finished building before a single chip goes in. Broadcom's chief executive made the dependency explicit on the company's September earnings call: "Before you get the chips out there, you have to get the data center shell in place and ready for production."

If the buildings stall, chip, networking, and cooling orders slow down after them. Each major company in the chain is currently posting growth figures that assume the expansion keeps going:

• NVIDIA (NASDAQ:NVDA) reported Data Center revenue of $89.02 billion, up 117%, guided the next quarter to $108.0 billion plus or minus 2%, and disclosed supply obligations of $279.00 billion in its latest SEC-filed earnings release.
• Broadcom (NASDAQ:AVGO) sees fiscal 2028 AI semiconductor revenue reaching $230 billion, a target that falls squarely inside Sacks's 2028 window.
• Arista Networks (NYSE:ANET) grew revenue 58.5% and guided Q4 to between $3.9 billion and $4.0 billion. The company also disclosed that a limited number of large customers drive much of that revenue, concentrating the risk.
• Vertiv (NYSE:VRT) reported organic orders up more than 100%, and its customers typically order 12 to 18 months ahead, which makes its order book a leading indicator for construction plans.

The power, cooling, and networking companies behind the data center buildings constitute a trade of their own, separate from the chipmakers that capture most of the attention.

What did the market selloff reveal about the landlords?

Over the month ending November 6, the hardware names fell hard: NVIDIA dropped 21.4%, Broadcom fell 22%, Arista lost 20.86%, and Vertiv declined 25.81%. Over the same month, the data center landlords barely moved. Equinix (NASDAQ:EQIX) slipped only 1.85%, and Digital Realty fell 3.47%.

That divergence supports the scarcity thesis. A construction freeze could help companies that already own permitted, powered sites, because canceled projects make existing capacity more valuable.

Equinix's chief executive said: "If there are a number of projects canceled, then it only makes what is already scarce capacity much more of a scarce resource." She added that across Equinix's 3 gigawatts of planned capacity, "the land, power and permitting are largely secured."

Digital Realty presents a similar position from the construction side. The company has 1.5 gigawatts under construction, with 63% of it pre-leased, and a record $2.5 billion backlog that gives it revenue visibility through 2027 and into 2028.

Is a freeze actually likely?

Sacks's view is a forecast, not a settled fact. Proposed moratoriums can be narrowed, delayed, or dropped, and no one yet knows how state policy will land.

The suppliers themselves are not forecasting a slowdown. Vertiv's chief executive described power, permitting, and labor as pacing items that "are not slowing down growth." NVIDIA expects fiscal 2028 revenue growth of approximately 70% and describes that outlook as limited by supply, with customer demand running higher than what the company can ship.

NVIDIA also cited top-five hyperscaler (the largest cloud infrastructure operators) capital expenditure of nearly $800 billion in 2026 and $1.3 trillion in 2027. That spending level is the demand foundation under every supplier figure listed above, and it is the number Sacks's permitting argument would effectively challenge.

Why does this matter beyond stock pickers?

Many investors own this trade without picking a single stock. A major Nasdaq-100 index fund's prospectus notes significant exposure to the information technology sector, so any slowdown in AI spending would show up in ordinary 401(k) and IRA balances.

Four signals will indicate which side of the argument is winning:

1. State action: whether moratorium talk in the big data center states turns into passed rules or stays at the proposal stage.
2. Guidance checks: NVIDIA's results against its $108.0 billion quarterly guide, and Broadcom's results against expected Q4 AI revenue of $21.7 billion.
3. Vertiv orders: because customers order 12 to 18 months ahead, a slowdown in Vertiv's order book would be one of the first signs that 2028 projects are being pushed back.
4. REIT pre-leasing and pricing: rising rents at Equinix and Digital Realty would suggest scarcity is helping the landlords even as new construction slows.

The dividing line for the next two years is now clear. If permitting tightens, investors with heavy index exposure to AI hardware need to know which parts of the supply chain depend on new construction, and which ones collect rent on capacity that is already built.
