## Key facts

- Up to 30% of data centers may avoid grid connections by 2030 and operate as island grids. [cites: 1793014680797182642]
- Every day of grid-connection delay costs a 100 MW data center around $1 million. [cites: 1793014680797182642]
- Form Energy raised $750 million in August 2026 at a pre-money valuation of $1.75 billion. [cites: 1793014680797182642]
- AI-related capital expenditure is expected to exceed $1.6 trillion by 2030, and companies would need nearly $2.5 trillion in sales by then to justify it at a 15% return on invested capital. [cites: 1793046890715695338]
- 2026 is the last year hyperscalers can fund capital expenditure growth solely through operating cash flows. [cites: 1793046890715695338]
- Hyperscaler capital expenditure has grown 86.5% year over year. [cites: 1793019473260113106]

## Power is now a data center product

Long-duration energy storage is shifting from a future grid requirement to a near-term necessity for hyperscalers facing multi-year grid connection queues, according to World Fund. Data center operators are signing contracts to secure always-on power for islanded renewable grids, and World Fund estimates that up to 30% of data centers may avoid a grid connection altogether by 2030 and operate as island grids. [cites: 1793014680797182642]

The economics are driven by delay: every day of delay costs a 100 MW data center around $1 million. World Fund requires long-duration technologies to reach an added energy cost under $20 per kilowatt-hour to be competitive, and notes that arbitrage alone will not pay back a 100-hour battery asset. Successful technologies must decouple energy and power costs to beat lithium-ion at durations beyond 15 hours. [cites: 1793014680797182642]

Capital is already moving: Form Energy raised $750 million in August 2026 at a pre-money valuation of $1.75 billion. But World Fund cautions that most long-duration storage companies are raising money for a market that might not go mainstream until the 2030s. [cites: 1793014680797182642]

## The revenue arithmetic

Janus Henderson portfolio managers Denny Fish and Jonathan Cofsky put the payback question in numbers. Annual AI-related capital expenditure is expected to top $1 trillion in 2027 and exceed $1.6 trillion by 2030. At a 15% return on invested capital and a 30% operating margin, the companies writing the checks would need to generate nearly $2.5 trillion in sales by 2030 to justify that spending. [cites: 1793046890715695338]

The funding model is also changing. Janus Henderson says 2026 represents the last year that hyperscalers, in aggregate, can fund capital expenditure growth solely through cash flows, and that some will increasingly rely on debt issuance. Bottom-up revenue projections, the managers add, currently fall short of what the top-down model requires, though companies may accept lower return targets or higher margins to stay competitive. [cites: 1793046890715695338]

One escape valve in the analysis: sovereign governments view AI as essential to economic health and national security, so their spending is not return-driven. And if companies accept a 10% return on invested capital instead of 15%, required revenues could be 33% less than the baseline scenario. [cites: 1793046890715695338]

## The fiber warning

State Street draws the historical parallel. Hyperscaler capital expenditure has grown 86.5% year over year, but investment expands capacity, and expanding capacity can move scarcity and economic rents to new parts of an ecosystem. The 1990s telecom buildout is the cautionary tale: Global Crossing and WorldCom aggressively financed the fiber groundwork, then entered bankruptcy as demand and capacity dynamics changed. [cites: 1793019473260113106]

Falling unit costs may accelerate adoption while making it harder for undifferentiated infrastructure providers to sustain margins, State Street argues. The long-term beneficiaries, in its view, may instead be healthcare companies that improve productivity through automation, financial institutions that combine AI with complex operational needs, and industrial firms that embed AI into processes. [cites: 1793019473260113106]

State Street's numbers underline the rotation: expected IT earnings growth is 41.8% for 2026-27 and 26.8% for 2027-28, while earnings growth expectations for industrials and financials remain comparatively resilient and improve going into 2028. [cites: 1793019473260113106]

The practical advice is to distinguish between volume growth and economic rent capture: a sector can grow enormously while the profits pool somewhere else entirely. [cites: 1793019473260113106]

## What is still unresolved

- Whether long-duration storage reaches sub-$20/kWh added energy cost in time for the island-grid data center wave.
- Whether hyperscaler revenues close the gap Janus Henderson identifies, or return targets are lowered instead.
- Which industries actually capture the rents if infrastructure margins compress as State Street expects.

## Decision card

- **Useful for:** Investors underwriting AI infrastructure exposure and founders selling into the data center buildout.
- **Not for:** Anyone seeking a verdict on whether the AI buildout is a bubble: these are three frameworks, not a call.
- **Compare against:** The 1990s telecom buildout and the cloud infrastructure cycle that followed it.
