Artificial Intelligence (AI) is catalyzing a multi-year capital investment cycle across technology, utilities, and energy. While long-term productivity gains or business model disruption may ultimately reshape certain corporate profiles, the immediate impact on credit markets is elevated capital expenditures, surge in bond issuance, and rising leverage.
Five Key Takeaways
- AI IS DRIVING A STRUCTURAL INCREASE IN INVESTMENT GRADE (IG) BOND SUPPLY
Hyperscaler issuance exceeded $100 billion in 2025 and is expected to continue growing in 2026. Utilities issuance is also at record levels. This marks one of the largest coordinated supply expansions in recent IG credit history. - FUNDAMENTALS REMAIN MANAGEABLE - FOR NOW
Large technology issuers entered this cycle with exceptionally strong balance sheets and regulated utilities benefit from supportive frameworks. However, free cash flow compression and higher leverage are creating nearterm pressure on spreads and ratings given uncertain long-tern return on investment. Management response and financial policy remain central to credit profile. - TECHNICAL BACKDROP MATTERS
Spread performance is increasingly sensitive to capital expenditure (capex) guidance and issuance expectations. Persistent supply may contribute to sector-level spread fatigue. - UTILITIES FACE OVERBUILD AND AFFORDABILITY RISKS
AI-related demand supports long-term rate base growth but introduces customer concentration and stranded asset risk as marginal projects prompt further grid CapEx. - ENERGY IS A SECONDARY BENEFICIARY
Natural gas demand supports midstream and gas-levered exploration and production (E&P) companies, but disciplined financing limits spread volatility.
Introduction
Artificial Intelligence (AI) is reshaping the global corporate credit landscape through a multi-year capital investment and funding cycle. While AI is often framed as a productivity and earnings story, its more immediate impact is being felt in credit markets through elevated capital expenditures (capex), rising leverage, and a sustained increase in bond issuance. In that sense, AI is as much a capital allocation story as it is a technology story, and for investment grade (IG) credit, the funding dynamics are likely to matter sooner than the margin benefits.
The scale and coordination of the current buildout are notable. Large hyperscale technology companies are investing aggressively in data center capacity, while regulated utilities are expanding generation and grid infrastructure to meet rising power demand. Unlike prior capex cycles, many of the issuers funding this expansion enter the period from positions of financial strength or operate within regulated frameworks that support cost recovery. As a result, near-term pressure on credit metrics appears manageable, even as free cash flow is compressed and leverage edges higher. The ultimate return on these investments remains uncertain, but balance sheets are starting from a position of resilience.
More immediately, the technical implications of this investment cycle are coming into focus. Hyperscalers that historically accessed the bond market only intermittently are now issuing tens of billions of dollars annually, often across longer maturities. Utilities issuance has also reached record levels as capital plans expand.
The resulting increase in supply and expectations for continued issuance over the next three-plus years represents a structural shift in the IG market’s composition.
Persistent supply may contribute to sector-level spread pressure and greater sensitivity to capex guidance, particularly if issuance outpaces incremental demand.
Over time, AI infrastructure requirements are likely to become an important driver of credit dispersion. Issuers that can translate investment into durable cash flows while maintaining disciplined funding strategies should emerge stronger. Those facing execution risk, regulatory friction, or weaker monetization could see greater pressure on spreads and ratings.

Sector Implications
While there are also emerging risks to business model disruptions in parts of the market from AI, we focus this paper on the implications of broadly increasing capex. The AI investment cycle affects credit markets through three primary channels:
1. Elevated capital expenditures
2. Increased funding needs and issuance
3. Evolving balance sheet and rating dynamics.
These channels manifest differently across sectors depending on business model, regulatory structure and capital intensity. We examine these dynamics across technology, utilities, and energy.

Technology
AI offers meaningful long-term growth opportunities for large technology issuers, but sector risks are rising as return on investment (ROI) remains uncertain and longer-term disruption risks emerge. Hyperscalers are expanding aggressively to meet compute demand, presenting fundamental and technical pressures.
Relative to prior industrial capex cycles, large-cap technology issuers enter this period from positions of exceptional financial strength. Robust free cash flow generation, strong balance sheets and diversified revenue streams provide meaningful flexibility to absorb near-term execution risk.
AI-related capital expenditures are being funded through a combination of internal cash flow and incremental debt issuance. In 2025, hyperscalers issued more than $100 billion of IG debt to finance data center buildouts. We expect net debt supply from this cohort to increase by roughly 30% to 50% in 2026, potentially reaching $130 billion to $150 billion1 .
This issuance wave is altering the composition of the IG market. Tech’s index weight could rise from ~10% to more than 12% of the overall benchmark, with issuance skewed toward longer maturities (10–30 years)2,3. The result is both greater sector representation and incremental duration extension within IG indices.
Funding is not confined to public IG markets. Issuers are also tapping private credit, securitized markets, high yield and non-USD funding channels, contributing to a structurally broader capital-markets footprint.
From a fundamental perspective, the near-term credit impact appears manageable given the strong starting point. However, elevated capex compresses free cash flow and increases leverage, introducing greater sensitivity to execution and monetization timelines.
Supply-demand dynamics remain critical. Spread performance for AI-related technology issuers has closely tracked capex guidance and perceived rating risk.
Periods of accelerated issuance or upward revisions to capital plans have coincided with increased spread volatility. Despite the constructive long-term backdrop, the AI investment cycle is likely to remain modestly credit-negative in the near term until investors see clearer evidence of returns and stabilization in credit metrics.
Many hyperscalers retain substantial untapped debt capacity at current ratings and have publicly committed to preserving investment-grade status, which should help contain rating risk over the cycle.

U.S. Utilities
AI-driven compute demand has framed power supply as a critical bottleneck, positioning regulated utilities as key enablers of the infrastructure buildout. Demand growth should support rate-base expansion and earnings visibility over time. However, the acceleration in AI-related capital plans has materially increased investment needs. Utilities are expanding generation and grid infrastructure, in some cases at record levels, to meet anticipated data-center demand.
Utilities rely heavily on IG debt financing, and issuance has risen in tandem with capital plans. U.S. IG utilities issuance reached approximately $135 billion in 2025, with expectations for ~$145 billion in 20264. Rising debt-funded capital expenditures have pressured leverage metrics. Many issuers have supplemented debt with equity issuance and asset sales, some regulators and state legislatures have adapted frameworks to facilitate cost recovery. Nonetheless, higher capital intensity increases dependence on constructive regulatory treatment and continued access to debt markets.
The near-term credit profile for the sector remains broadly stable, though balance sheets are weaker as capital plans expand. As new investments enter rate base, they should generate durable incremental cash flows, supporting longer term credit stability.
Risks are not uniform. As utilities move from using spare grid capacity toward building new generation for anticipated load, the risk of overinvestment or underutilized assets increases. Customer concentration, affordability concerns and potential political intervention represent emerging idiosyncratic risks. From a technical perspective, elevated issuance may contribute to modest spread pressure, particularly if supply persists alongside leverage expansion.
European Utilities
AI-related power demand in Europe is likely to be incremental rather than transformational. Utilities are already engaged in significant investment programs tied to renewable expansion and grid modernization.
Funding increases should be broadly manageable within existing financial buffers. Credit outcomes will depend on regulatory recovery mechanisms, the scale and timing of required investments and the degree to which incremental AI demand competes with existing industrial or residential consumers.
Energy
Natural gas is forecast to represent roughly 30% of incremental power generation between 2024 and 2030, reflecting the need for reliable, dispatchable energy to support AI-driven compute demand5 . U.S. natural gas demand is projected to rise by approximately 25 billion cubic feet per day (bcf/d) to 138 bcf/d by 2030, implying meaningful infrastructure investment.
As shown in Display 4, planned U.S. generation capacity additions accelerate materially through 2027–2028, reinforcing the scale of infrastructure required to support AI-driven electricity demand.
Midstream capital expenditures rose roughly 38% year-over-year in 2025, with 70–80% of project backlogs tied to gas pipeline development6. However, balance sheets across the sector remain strong, and rising cash flow generation has limited incremental funding needs. AI-linked projects are typically underpinned by long-term contracts with utilities and increasingly data centers, improving visibility and diversification.
We expect midstream issuers to maintain conservative financing policies in 2026, limiting issuance growth and reducing the risk of material spread widening. Gas-levered E&P issuers may benefit modestly from structurally higher gas prices and bond scarcity value. Overall, AI demand is supportive but not transformative from a credit perspective.
Conclusion
AI infrastructure requirements are reshaping credit markets most directly in U.S. technology and utilities, with secondary effects in European utilities and U.S. energy. While long-term productivity gains may ultimately support earnings and cash flow, the immediate impact is being transmitted through elevated capital expenditures, rising leverage and increased bond supply.
For bond investors, the key question is not whether AI will drive growth, but how that growth is financed and monetized. Issuers that convert investment into durable cash flows while maintaining disciplined balance-sheet management should emerge stronger. Those facing execution risk, regulatory friction or prolonged monetization timelines may experience greater spread volatility and rating sensitivity.
As a result, AI is poised to become an increasingly important driver of credit dispersion and opportunity over the coming cycle. Over time, it may evolve from a thematic overlay to a structural feature of credit market analysis.

Risk Considerations
There is no assurance that a portfolio will achieve its investment objective. Portfolios are subject to market risk, which is the possibility that the market values of securities owned by the portfolio will decline and that the value of portfolio shares may therefore be less than what you paid for them. Market values can change daily due to economic and other events (e.g. natural disasters, health crises, terrorism, conflicts, social unrest, etc.) that affect markets, countries, companies or governments. It is difficult to predict the timing, duration, and potential adverse effects (e.g. portfolio liquidity) of events. Fixed-income securities are subject to the ability of an issuer to make timely principal and interest payments (credit risk), changes in interest rates (interest-rate risk), the creditworthiness of the issuer and general market liquidity (market risk). In a rising interest-rate environment, bond prices may fall and may result in periods of volatility and increased portfolio redemptions. In a declining interest-rate environment, the portfolio may generate less income. Longer-term securities may be more sensitive to interest rate changes. Catalyst events, such as AI , Crypto, and Tokenization adoption, carries the risk that such catalysts may not occur, may be delayed, or that the market may react differently than expected. Companies focused on these areas may have limited product lines, markets or financial resources, and their management and performance may be particularly impacted by events that adversely affect AI adoption, such as rapid changes in product technology cycles, product obsolescence, government regulation, cybersecurity concerns and competition.
