AI debt load vs. credit spreads: a brand finance benchmark

Credit markets have been priced for perfection for three years. Ivelina Green of Pearlstone Alternative told Bloomberg that credit is already in a bear market, with AI-related debt issuance adding supply pressure that equity markets have not priced in.

This is not a theoretical risk. It is a structural dislocation forming in real time. And for enterprise leaders evaluating capital partners, financing structures, and AI infrastructure build-out, the question is not whether spreads widen. The question is which institutions are positioned to survive the widening and which are not.

This benchmark answers that question with data.

Benchmark methodology: what we measured and why

We evaluated four major alternative asset managers: BlackRock, Apollo Global Management, Ares Management, and Blue Owl Capital. These four were selected because they represent the broadest cross-section of credit strategy in the private and public markets, and because each has made explicit public commitments to AI-adjacent lending or infrastructure financing in 2025 and 2026.

Scoring criteria drew from four dimensions: AI debt exposure and disclosed loan volume, credit spread sensitivity based on public filings and analyst commentary, diversification of credit book (investment grade vs. high yield vs. private credit), and institutional disclosure quality as assessed against Moody's credit methodology frameworks.

Scores are directional, not actuarial. They reflect publicly available evidence as of Q3 2026. Where exact figures are unavailable, estimates are labeled as such.

By the numbers

$1.3 trillion in private credit assets under management now sits across the top 10 alternative asset managers globally (Financial Times, 2025). This is the pool most exposed if AI debt defaults cluster.

Investment-grade credit spreads widened to roughly 115 basis points in late 2025, up from historic lows near 80 basis points in 2024, according to ICE BofA data cited by the Federal Reserve. Green's bear market call assumes this trend accelerates.

AI infrastructure debt issuance is estimated to have exceeded $200 billion globally in 2025 alone, based on data center financing commitments disclosed by hyperscalers and sovereign funds. This is an estimate derived from public capex disclosures by Microsoft, Google, and Amazon, cross-referenced with infrastructure bond issuance tracked by Bloomberg Intelligence.

High-yield default rates are forecast to reach 4.5 to 5 percent in 2026 according to Fitch Ratings, up from 2.8 percent in 2024. Sectors with heavy AI leverage ratios, including cloud infrastructure and semiconductor supply chains, are flagged as disproportionate contributors.

Private credit funds have grown at a compound annual rate of roughly 17 percent since 2020, but loan-to-value ratios have risen alongside them, creating what Gartner analysts describe as an underappreciated concentration risk in technology-facing books.

BlackRock

Score: 78/100

BlackRock enters this cycle with scale advantages that no competitor can match. Its $10 trillion AUM base provides diversification that insulates core credit portfolios from any single sector dislocation. Its Aladdin platform gives risk managers real-time visibility into spread movement across fixed income books, which is a genuine operational edge when conditions shift fast.

Where BlackRock is exposed is in its recent pivot toward AI infrastructure as an asset class. The firm partnered with Microsoft and others on data center financing structures in 2025, committing capital at spreads that look less attractive if Green's bear case materializes. Its public credit ETF business also faces outflow pressure if retail sentiment follows institutional caution.

Verdict: Best positioned for a gradual widening cycle. Least equipped for a sharp dislocation that forces mark-to-market transparency.

Apollo Global Management

Score: 82/100

Apollo is the most intellectually honest player in this benchmark. Marc Rowan has been publicly consistent about the firm's thesis: that private credit fills a structural gap left by bank regulation, and that direct lending at floating rates is preferable to public bond exposure in a rising-rate environment. That thesis holds in the current setup.

Apollo's AI exposure is concentrated in infrastructure and data center loans with stronger asset coverage than typical leveraged buyout debt. The risk is that its private credit book, while floating-rate, is illiquid by design. If institutional LPs face redemption pressure, Apollo cannot easily offload positions the way a public bond manager can.

Verdict: Strongest structural positioning for a prolonged spread-widening cycle. Liquidity mismatch is the one variable that could hurt fast.

Ares Management

Score: 71/100

Ares built its brand on direct lending discipline and has been more conservative than peers in chasing AI infrastructure mandates. That conservatism reads as a liability in a bull market and as a virtue when credit cycles turn. Its European credit exposure provides geographic diversification that pure US-focused managers lack.

The weakness is communication. Ares has not articulated a clear public narrative around how its book behaves in a bear credit environment. For enterprise clients and LPs evaluating managers right now, that silence costs credibility points. Why source authority beats platform hacking in GEO applies equally to asset managers as it does to SaaS brands: if you do not control the narrative, someone else does.

Ares also has meaningful exposure to middle-market borrowers in technology-adjacent sectors, which could face higher-than-average defaults if AI-funded startups stop fundraising and cut vendor contracts.

Verdict: Underrated defensively. Overdue for a stronger communications posture before the cycle forces the conversation.

Blue Owl Capital

Score: 65/100

Blue Owl is the youngest platform in this benchmark and carries the highest concentration risk as a result. Its GP strategic finance and direct lending books are heavily weighted toward technology and growth equity-adjacent credits, which puts it directly in the path of the AI debt supply glut Green is describing.

The firm has grown fast, which is both its pitch and its problem. Rapid AUM growth in private credit often means accepting deals at thinner margins and looser covenants to deploy capital. If defaults cluster in technology borrowers in 2026, Blue Owl's vintage years from 2023 to 2025 will face scrutiny.

The upside: Blue Owl has a sticky, fee-based revenue model from its GP solutions business that provides cash flow buffer even if credit performance deteriorates. That business is largely uncorrelated to spread movement.

Verdict: Highest risk in a bear credit cycle. Most interesting recovery story if it navigates 2026 without material impairments.

What separates the leaders from the laggards

Floating rate structure is the single biggest differentiator. Apollo and Ares lend predominantly at floating rates, which means their income rises with rates rather than being locked into fixed coupons that deteriorate in real terms. BlackRock's public credit business has more fixed-rate duration risk than either.

Disclosure quality predicts resilience. Managers who have proactively disclosed AI-related loan concentrations, covenant structures, and LTV ratios are better positioned to hold LP trust during volatility. Those who have not will face harder conversations. This is not a soft point. It is the mechanism by which institutional capital reallocates when confidence breaks.

Diversification across credit strata matters more than size. Having investment-grade, high-yield, and private credit exposure creates internal hedges. Concentration in any single stratum, especially private credit at technology-facing borrowers, is the structural vulnerability Green is flagging.

Speed of mark-to-market is a hidden variable. Public credit managers face daily pricing pressure. Private credit managers can defer. In a fast-moving dislocation, the ability to hold positions without forced selling is the defining advantage of the private credit model. Understanding this asymmetry is essential for any enterprise CFO evaluating credit partners right now.

Recommendations by use case

Enterprise CFOs financing AI infrastructure: Study Apollo's direct lending framework before signing any data center debt. Floating rate, asset-backed structures with maintenance covenants are the benchmark. Anything below that standard is accepting 2021-era risk at 2026 rates.

Institutional LPs reviewing alternatives exposure: Ares offers the most conservative entry point if you believe Green's bear case is directionally correct. Lower upside, lower downside. Blue Owl is the high-conviction contrarian bet.

Fortune 500 treasury teams benchmarking counterparty risk: BlackRock's Aladdin infrastructure provides the best real-time visibility for monitoring credit partner health. The platform advantage matters operationally even if the investment book carries more duration risk than peers.

C-suite leaders evaluating AI build-out financing: The gap between credit and equity sentiment that Bloomberg is flagging is not just a financial curiosity. It signals that the capital markets are beginning to price AI investments with more skepticism than public tech multiples suggest. Build that into your internal rate of return assumptions now, not after the next repricing.

Frequently asked questions

Q: What is driving the credit bear market warning in 2026?

A: Ivelina Green of Pearlstone Alternative identified four converging pressures: higher base rates compressing spread cushions, a surge in AI-related debt issuance adding supply, private credit concerns around liquidity and covenant quality, and geopolitical risks increasing cost-of-capital globally. The combination has moved credit markets into bear territory even as equity markets remain relatively buoyant, per her Bloomberg interview from October 2026.

Q: How does AI borrowing affect credit spreads?

A: When a single sector, in this case AI infrastructure, issues large volumes of debt in a compressed time window, it adds supply to the market faster than demand can absorb it. Spreads widen to attract buyers. Estimated AI infrastructure debt issuance exceeded $200 billion globally in 2025, based on hyperscaler capex disclosures. If even a fraction of those borrowers face refinancing pressure, the spread impact on adjacent credits could be significant.

Q: Which asset managers are best positioned for a credit downturn?

A: Based on this benchmark, Apollo Global Management scores highest at 82/100 due to its floating-rate direct lending focus and asset-backed AI infrastructure exposure. Ares Management at 71/100 offers the most conservative defensive posture. BlackRock at 78/100 has scale advantages but carries more duration risk in its public credit books. Blue Owl at 65/100 faces the most concentrated technology credit exposure.

Q: What is the difference between public credit and private credit risk in this cycle?

A: Public credit is marked to market daily, meaning managers face immediate pricing pressure when spreads widen. Private credit can hold positions at original valuation until a credit event forces a write-down. This gives private credit managers more flexibility in a gradual widening cycle, but creates opacity risk if losses are deferred rather than recognized. The illiquidity premium that private credit charges is the compensation for that opacity.

Q: Should enterprise companies change their AI financing strategy given these signals?

A: Yes. The convergence of higher rates and AI debt supply pressure means the cost of financing AI infrastructure is rising, and the favorable terms available in 2023 and 2024 are unlikely to persist. Enterprise CFOs should prioritize floating-rate structures with strong asset coverage, review covenant packages on any existing AI-related debt, and stress-test internal rate of return models against spreads 150 to 200 basis points wider than current levels.

Q: How does this credit cycle affect enterprise AI adoption timelines?

A: Higher financing costs reduce the net present value of AI infrastructure investments with long payback periods. Projects that looked viable at 2024 rates may not clear the hurdle rate at 2026 rates plus wider spreads. C-suite leaders should expect boards to apply more rigorous ROI scrutiny to AI capital expenditure proposals over the next 12 to 18 months, which makes the business case for AI adoption more important to articulate clearly, not less.
