Moody's Warns 'Unprecedented' AI Spending Threatens Credit Quality of Six Hyperscalers; Direct Debt Hits ~$460 Billion
Moody's formal sector-wide credit warning — covering Amazon, Alphabet, Meta, Oracle, Microsoft and CoreWeave — projects $785 billion in AI capex in 2026 rising toward $1 trillion in 2027, with aggregate on-balance-sheet debt at ~$460 billion and off-balance-sheet data-centre lease commitments of ~$1.2 trillion. It signals that even fortress balance sheets are being strained and that Oracle (Baa2, negative outlook) and Ba3-rated CoreWeave face the greatest vulnerability.

S&P Global Ratings Downgrades Oracle to 'BBB-/A-3', One Notch Above Junk, on $250 Billion AI Data-Centre Spending Binge and OpenAI Concentration Risk
S&P cut Oracle to BBB- (lowest IG tier) on July 9, 2026, citing $167 billion in total debt, negative free cash flow of ~$42 billion over the prior four quarters, and extreme single-customer concentration (OpenAI ~50% of $638 billion RPO backlog). Moody's retained a negative outlook, making a further cut to junk a live risk. Oracle's 10-year bonds yield ~6.4% vs. the BBB curve at 5.7%, and its CDS is trading at multi-year highs — the most acute credit-stress story in the AI-capex cohort. NOTE: Dated July 9, 2026 — outside 48-hour window; no confirmed August 3–4 update found.

Goldman Sachs: $489 Billion of AI-Related Debt Issued in 2026 YTD, Already 52% Above Full-Year 2025; Amazon Alone Raises $53 Billion
Goldman's latest tally shows $489 billion in AI-related debt issued through late July 2026 — already 52% above the $322 billion issued in all of 2025 — with Amazon as the single largest borrower at ~$53 billion (including a $37 billion 11-part US bond and >$16 billion in euro-denominated notes). Tech now holds 18% of total US IG corporate debt issuance. The pace is stress-testing investor absorption capacity, with Amazon's July deal 2.5x oversubscribed but below the 3.2x cover on its March issue. NOTE: Dated ~July 28, 2026 — approximately 7 days outside the strict 48-hour window; no confirmed August 3–4 item found from a qualifying source.
