Bernstein: hyperscalers hold 42% of the credible US data center pipeline

The biggest names in cloud computing now own the largest slice of America’s data center future. According to Bernstein, hyperscalers account for 42% of the credible data center pipeline, more than any other group of developers.

Bernstein’s report, dated October 11, 2026, puts the total US data center project pipeline at 456 GW as of September 2026. That marks a jump of 52 GW, or 13%, from the month before.

Inside the numbers

Capacity actually under construction rose to 79.9 GW, up 7 GW month over month.

Hyperscalers contribute 68.7 GW to the pipeline, according to Bernstein. Three companies led the monthly additions: Google added 3.9 GW, Amazon added 3.8 GW, and Meta added 2.4 GW.

On the construction side, hyperscaler capacity being built totals 31.4 GW. Google, Amazon and Meta together represent approximately 80% of that figure.

Then there is the less flattering statistic. Deferred or shelved capacity reached a record 51.7 GW, equal to 11% of the total pipeline.

Bernstein ties much of that backlog to mounting local opposition and regulatory friction. According to the report, 27 US states are considering or implementing restrictions on new data centers, which affects whether projects get approved.

Power is the new bottleneck

Power availability has now overtaken capital as the primary constraint on data center growth. Grid interconnection queues and permitting timelines round out the list of obstacles.

The report also points to a broader market view in which only 35-40% of globally announced data center capacity is projected to be realized. Construction delays and rising costs are among the operational hurdles cited.

The builders themselves are also diverging in strategy. Hyperscalers are increasingly favoring larger, self-built campuses, while colocation providers are concentrating on densifying existing sites and developing smaller edge locations.

What this means for investors and the grid

Bernstein’s investment takeaway is straightforward. The firm reiterated its Outperform rating on the electrical equipment sector, naming Eaton, Hubbell and Quanta Services among its highlighted companies.

A record 51.7 GW of deferred or shelved capacity is a signal that approval is no longer a formality. Bernstein also flagged regulatory risks to the pipeline in the period following the midterm elections.

With 27 states weighing or enacting restrictions, data center siting is becoming a local political issue rather than a purely commercial one.
