AI Infrastructure: Cap Rates Versus Long-Term Bond Yields

Thesis

A practical framework for understanding when higher long-duration yields should compress infrastructure values and when contracted NOI growth can offset part of the pressure.

Key chart

The argument

The most durable AI-infrastructure asset is not necessarily the one with the lowest quoted cap rate. Durability comes from the quality and timing of cash flow, tenant credit, lease structure, power economics, maintenance obligations, financing, and residual utility.

A development-stage project has more duration than an operating leased facility because cash outflows occur before cash inflows. That makes it more sensitive to discount-rate changes even if the future asset could eventually trade at a core-infrastructure cap rate.

Key findings

• The relevant benchmark depends on duration, not merely the current policy rate.
• Debt pricing can reveal the market's view of project and counterparty risk before public-equity multiples adjust.
• Contracted escalators support value only if the tenant pays, the asset remains competitive, and capex does not absorb the growth.
• A rising cap rate and rising NOI can occur simultaneously.
• A lower nominal cap rate can still produce a poor equity return if the investor overpays, uses expensive leverage, or funds large future capex.

Counterarguments

Strong data-center demand, scarce power, and contractual escalators can offset higher rates. A tenant may also fund equipment or construction, reducing equity duration.

However, scarcity should be evidenced in binding economics. Pipeline demand, letters of intent, and broad market forecasts do not provide the same protection as a contract with credit support and enforceable remedies.

Risks

The framework can mislead if debt and equity claims have different collateral, duration, covenants, and residual rights. Public company overhead, taxes, development losses, and dilution also separate equity value from property value.

Catalysts

A refinancing, asset sale, debt issuance, lease signing, or disclosed project yield can provide a market-observable anchor. Changes in the long end of the yield curve should be reviewed alongside credit spreads and inflation expectations.

Scenario analysis

Valuation analysis

Suppose a stabilized asset produces $100 million of forward NOI. At a 6% cap rate, the implied asset value is approximately $1.67 billion. At a 10% cap rate, it is $1.0 billion. That simple comparison is useful, but it omits construction spending, lease-up, financing, taxes, ownership, and terminal capex.

A full equity DCF should therefore model cash flow from today through stabilization and use a residual value only after the asset reaches the assumptions embedded in the exit cap rate.

Assumptions

The linked sample framework exposes Treasury yield, debt spread, incremental equity premium, NOI, NOI growth, and cap rate. None of those should be inferred from one another without checking the contract and capital structure.

Methodology

The preferred hierarchy is:

1. price current project debt or comparable secured debt;
2. identify the equity risks not borne by debt;
3. model construction-period cash flow and dilution;
4. model contracted NOI and capex obligations; and
5. select a terminal cap rate consistent with asset quality and duration.

Disconfirming evidence

The higher-rate bear case would be weakened by falling long-duration yields, tighter project spreads, higher-quality tenant guarantees, customer-funded capex, or asset transactions at lower cap rates.

The scarcity bull case would be weakened by power bottlenecks, tenant cancellations, rapid technology obsolescence, or evidence that rent growth is offset by equipment and energy costs.

What would change the conclusion

The conclusion changes when the market provides a better observable: project debt pricing, a comparable asset sale, a binding lease with transparent economics, or operating NOI with a credible growth record.
