Life insurers bought $85 billion of AI credit, and Moody's says it undercounts

America's life insurers, the most patient money in the market, have quietly become buyers of the AI debt complex. Moody's▼−2.02% — Moody's, down 2.02 percent today Ratings counted about $85.2 billion of AI-linked investments in their general accounts at the end of June 2026↗, up 24% from $69 billion at the end of 2025 ¹. That is only 1.4% of their cash and invested assets, but the direction and the speed are the story: Moody's expects another $50 billion to $100 billion added by the end of 2027. ¹

The fast slice is data centers

The fastest-growing piece is digital infrastructure debt: $39.5 billion at mid-year, up 34% in six months, funding data center buildings, power and the GPUs and TPUs inside them ¹. Most of it is still investment grade, but the share rated below investment grade rose from 4.7% at end-2025 to 6.1% in the second quarter ¹. Direct debt from the five hyperscalers Moody's tracks, Alphabet▼−0.43% — Alphabet, down 0.43 percent today, Amazon▼−0.39% — Amazon, down 0.39 percent today, Meta▼−0.67% — Meta, down 0.67 percent today, Microsoft▲+0.84% — Microsoft, up 0.84 percent today and Oracle▲+1.70% — Oracle, up 1.70 percent today, adds $32.2 billion, up 21%, with Oracle at about $10 billion and Amazon at $8.5 billion. ¹

Moody's admits it cannot count it all

Here is the complication the rating agency itself flags: much of this exposure runs through special purpose vehicles, joint ventures, alternative funds, commercial mortgages and collateralized loan obligations, so Moody's says its figure likely understates the industry's true exposure. Repayment of much of the digital-infrastructure debt, it writes, rests on a short list of borrowers: CoreWeave▼−1.32% — CoreWeave, down 1.32 percent today, OpenAIPVT$1.18T — OpenAI, private, latest valuation $1.18T, AnthropicPVT$350B — Anthropic, private, latest valuation $350B, Nvidia▼−0.23% — Nvidia, down 0.23 percent today, Broadcom▲+0.52% — Broadcom, up 0.52 percent today and AMD▲+1.59% — AMD, up 1.59 percent today. ¹

Those are precisely the credits the bond market repriced this month. CoreWeave's unsecured debt yielded about 15% as of October 21↗, its five-year credit default swaps stood at 1,145 basis points, up 39% in October, and the stock is down 36% this month ³. The company has $20.7 billion of debt due through 2030, analysts at Baird estimate it needs roughly $30 billion of new capital in 2027, and credit desks told CNBC the high-yield market for data center paper is effectively on hold until after the midterms. ³

The bull case, and what decides it

The other side deserves its say. Goldman Sachs▼−0.85% — Goldman Sachs, down 0.85 percent today, JPMorgan and Barclays▼−1.34% — Barclays, down 1.34 percent today all published bullish notes on CoreWeave this week; Goldman's analysts, upgrading to buy, wrote that CoreWeave is "likely in the top quartile of neoclouds, if not the top decile," with investment-grade customers like Microsoft and Meta behind it. Moody's itself concludes the exposure remains a modest share of insurers' assets. ¹³

Fair. But the five hyperscalers' disclosed future commitments jumped about 130% to $2.8 trillion, and Moody's expects insurers to keep funding the investment-grade debt behind the buildout ¹. If CoreWeave and the other named borrowers hold, the insurers collect fixed income at 15% yields on money backed by policyholders ¹³. If the credit breaks, the losses land on those same policyholder portfolios. Watch CoreWeave's third-quarter report next month: the bond yield, and how much of its roughly $30 billion 2027 capital need gets funded, will tell which. ¹³
