Meta Credit Risk Gauge Surges to All-Time Record on AI Spending Plans, CDS Hits 119.3 bps Intraday
Meta's 5-year CDS spread hit an all-time intraday high of ~119.3 bps (per ICE Data Services), triggered by Meta raising the low end of its 2026 capex guidance to $135B (high end $145B). Having already sold $55B in bonds over the past year ($30B in Oct 2025 and $25B in Apr 2026), credit markets are now pricing a record risk premium on the name. The contagion spread to Oracle and other hyperscaler CDS as well, signalling broad credit-market stress across AI-capex issuers.

Janus Henderson Fund Manager Defends CoreWeave Debt Holding as 9.75% 2031 Bonds Yield Nearly 16%, Up 70%+ Since April Issuance
CoreWeave's 9.75% bonds due 2031 are yielding ~15.97%—more than 70% above their April issuance yield—while 5-year CDS sit near 1,082 bps (distressed territory). With $51.6B in total debt, interest expense of $640M last quarter exceeding operating income, and Q3 interest guided at $860M–$940M, CoreWeave is the most acute credit-stress flashpoint in AI capex. The story crystallises the divergence between equity bulls and credit bears in the AI infrastructure trade.

Oracle 5-Year CDS Widens to 315 bps — A 311% Increase Year-on-Year — as Credit Markets Flag Bellwether AI Debt Risk
Oracle's 5-year CDS spread widened to 315 bps on Oct 19–20, a 311% year-on-year surge, cementing its status as the 'canary in the coal mine' for investment-grade AI credit per economist David Rosenberg. With $169B in total debt, a BBB− S&P rating (cut July 9, 2026), Moody's negative outlook (Baa2), negative free cash flow of −$23.7B in FY2026, and $260B in off-balance-sheet data-centre leases, Oracle bridges junk-rated neoclouds and IG hyperscalers—making its CDS widening a systemic signal for the $228B+ in bonds issued by Alphabet, Amazon, Meta, and Oracle collectively in 2026.
Method. OAS = option-adjusted spread over the bootstrapped US Treasury zero curve (from FRED CMT par yields) that reprices each bond's cash flows to its FINRA clean price. For the callable high-yield names (CoreWeave, SpaceX) the embedded call is valued on a Black-Derman-Toy short-rate lattice (CMT curve, lognormal vol per name) and its cost subtracted; the remaining bonds' calls are out-of-the-money (par-call near maturity) so their OAS equals the Z-spread to within a fraction of a bp. Illiquid bonds without a fresh TRACE print carry their last price forward, flagged no trade Nd. Level %ile = today's OAS within the bond's own history; Δ %ile = today's 1d/1w change within all historical same-horizon changes (100 = most extreme widening); PERCENTRANK.INC, suppressed below n=60. The trend sparkline spans each bond's last 90 sessions (shorter if its history is shorter) so all names cover a common window. Watch HY (CoreWeave, SpaceX) blowing out while IG (Meta, Oracle) holds — that divergence is the funding-stress tell.
