How AI Is Fueling an Increase in Junk Bond Yields — And What It Means for Capital Markets

Artificial intelligence has become the defining capital expenditure theme of this market cycle. The surge in demand for GPUs, data centres, cloud infrastructure, and AI-driven software has pushed companies across sectors to raise unprecedented amounts of capital. While public equity markets celebrate the potential upside of AI, the credit markets are signalling a very different story: AI is helping drive a notable rise in high-yield (junk bond) issuance and contributing to widening spreads.

How AI Is Fueling an Increase in Junk Bond Yields — And What It Means for Capital Markets

A CV5 Capital Insight

As a Cayman institutional fund platform, CV5 Capital monitors strategic market shifts that impact credit managers, macro funds, and multi-strategy investors. The AI build-out is not only a technological revolution, it is a capital structure revolution reshaping high-yield markets.

AI: A Capital-Intensive Transformation

Scaling AI requires sustained, heavy investment:

  • hyperscale GPU data centres
  • AI-ready semiconductor supply chains
  • cloud compute capacity
  • specialised networking and edge infrastructure
  • high-cost technical talent
  • generative AI model training and deployment

Even well-established corporates find that internally generated cash flows cannot keep pace with the exponential growth in AI expenditures. As a result, lower-credit-quality companies have turned increasingly to junk-bond markets to fund the AI race.

Real-World Market Examples: How AI Is Driving Junk Bond Issuance

Below are concrete examples across sectors demonstrating how AI-driven investment needs are pushing companies into the high-yield market and helping drive yields higher.

1. Data Centre Developers Issuing More High-Yield Debt

AI compute demand requires enormous power density and GPU-ready facilities. As a result, data centre operators have become major high-yield issuers.

DigitalBridge-backed portfolio companies

Multiple operators backed by DigitalBridge have issued high-yield bonds to finance hyperscale data-centre expansions tailored for AI workloads.

Stack Infrastructure and QTS (Blackstone-owned)

Both have tapped junk-bond and private credit markets to fund multi-billion-dollar AI campuses with long-dated ROI profiles.

Why this matters:

These projects are capital-intensive, often leveraged, and take years to reach profitability, conditions that push yields higher.

2. Telecom and Fibre Network Providers Funding AI Traffic Growth

AI cloud workloads require ultra-low-latency fibre connectivity and higher bandwidth.

Lumen Technologies (one of the largest HY issuers in the US)

Lumen refinanced and expanded high-yield debt to overhaul fibre networks that will carry AI-enriched traffic.

Frontier Communications

Raised high-yield debt to accelerate fibre deployment as AI drives bandwidth growth.

Zayo Group

Issued multiple HY tranches to expand next-generation connectivity for AI data transport.

3. Semiconductor and AI Hardware Supply Chain Leveraging Junk Bonds

AI demand is straining the semiconductor ecosystem, pushing mid-cap players to issue high-yield instruments.

Wolfspeed (SiC semiconductor manufacturer)

Issued significant high-yield debt to build silicon carbide fabrication capacity used in power-intensive AI infrastructure.

Coherent Corp.

Raised high-yield funding to expand optical and photonic components critical for GPU interconnects and AI networking.

4. Cloud Compute Providers Turning to High Yield

OVHcloud

Issued high-yield bonds to expand European GPU cloud and AI-hosting infrastructure.

CoreWeave

Although private, CoreWeave has tapped billions in private high-yield credit (Blackstone, BlackRock, Magnetar) to finance rapid GPU deployment.

Cyxtera

Used high-yield financing in restructuring to rebuild AI-optimised hosting infrastructure.

5. AI Adoption Forcing Legacy Corporations Into Higher Leverage

AI-driven upgrades across industries—manufacturing automation, logistics optimisation, AI healthcare platforms, have required companies with sub-investment-grade ratings to issue junk debt.

Examples include:

  • industrial automation upgrades
  • warehouse robotics modernisation
  • AI-enabled logistics planning
  • healthcare diagnostics AI integration

These corporates carry middling cash flow stability and therefore must pay higher yields to raise capital.

6. Private Equity Portfolio Companies Funding AI Transformation Through High Yield

PE-owned companies in:

  • business services
  • healthcare IT
  • insurance administration
  • education technology
  • consumer platforms

have increasingly issued high-yield debt to fund AI-driven system transformations.

PE sponsors may be accelerating AI investment to maintain competitiveness, monetise data, or prepare companies for exit, often ahead of actual cash-flow returns.

Why Junk Bond Yields Are Rising

The combination of heavy issuance and greater perceived execution risk is driving yields higher. Key factors include:

Increased High-Yield Supply

More issuers are entering the market to finance AI capex.

Long-Dated, Uncertain Payoffs

AI capex often generates returns years later, causing investors to demand higher compensation.

Higher Leverage Profiles

Debt-funded AI adoption inflates leverage ratios, a core determinant of junk-bond pricing.

Macro Conditions

Elevated interest rates exacerbate the credit burden.

What This Means for Fund Managers

1. Enhanced Opportunity in High-Yield Credit

Rising spreads can create attractive asymmetry for credit managers who can distinguish between structurally strong and weak issuers.

2. Larger Dispersion = Better Alpha Environment

AI will create clear winners and losers—ideal for long/short credit strategies.

3. Cross-Asset Opportunities

AI-driven credit stress may create mispricings in:

  • convertibles
  • secured loans
  • distressed opportunities

4. Structural Shift in Capital Allocation

AI is a multi-decade CapEx cycle—managers who understand its credit implications will be ahead of the market.
