AI debt worries spark surge in default insurance trading
Investors are buying credit default swaps (CDS) on AI-linked borrowers at a record pace to protect themselves in case the AI boom unravels. More than $9bn of CDS tied to bonds of Oracle, SpaceX, Alphabet, Amazon, Meta, Broadcom and Nvidia traded on average each week in September, up from less than $2bn in July (Morgan Stanley Research), and US corporate CDS index volumes this year have already overtaken last year's total (Bloomberg data). Prices hit records this month even for names seen as safe. Five-year Meta CDS reached 108bp (it costs $108,000 a year to insure $10mn of debt) and Nvidia 101bp, both records. Protection on Alphabet and Amazon is at all-time peaks, and Microsoft spreads have climbed too. Riskier names trade far wider: Oracle was quoted at 322bp on Monday (144bp at the start of the year) and SpaceX at a record 226bp (110bp when its CDS began trading in late June). The neocloud CoreWeave, some of whose bonds are in distressed territory, trades around 1,090bp: $10mn of protection costs $1.82mn upfront plus $125,000 a quarter. The driver is debt. AI-linked issuance is an estimated $466bn so far in 2026, against $101bn in the same period of 2025 (Morgan Stanley), although borrowing has slowed from its June peak. Buyers include bond investors hedging their books and, increasingly, multi-asset and equity managers who see CDS as a 'cheap hedge' compared with expensive equity puts on volatile stocks (Jim Caron, Morgan Stanley IM), which itself pushes prices up. 'The market is increasingly focused on two things: CDS and free cash flow,' says Manish Kabra (Société Générale). Gavan Nolan (S&P Global Market Intelligence) sees a 'complexity premium' from the sector's interlinked financing, and investors are buying protection on OpenAI and Anthropic suppliers such as Oracle and Alphabet. Robert Dafforn (Polus Capital) warns of 'very highly levered' borrowing and says 'whatever the weakest link is' could drag down the system. Caveats: big-tech spreads remain low in absolute terms compared with the riskier AI names; part of the price rise reflects hedging demand from non-credit investors; and the weekly volume figure is a Morgan Stanley Research estimate covering seven names.
Why it matters
Credit markets are now pricing AI risk on the hyperscalers themselves, not just the neoclouds. That goes beyond yesterday's $10tn-fray overview and Anthropic's ~10% Blackstone coupon (other 10-19 #1 and #5) with a fresh, quantified signal: weekly hedging volumes up more than fourfold in two months and record spreads at Meta, Nvidia, Alphabet and Amazon. For Dealroom, CDS and free cash flow become the dashboards for the AI funding cycle. Rising protection costs feed into financing costs for data-centre builders and neoclouds (CoreWeave and, by extension, Amsterdam-based Nebius) and into the IPO window for Anthropic and others. This week's Big Tech earnings (capex vs free cash flow) are the next test.
Executive takeaways
Volume: more than $9bn a week of CDS on seven AI-linked names (Oracle, SpaceX, Alphabet, Amazon, Meta, Broadcom, Nvidia) in September, against less than $2bn in July (Morgan Stanley Research). US corporate CDS index volumes year to date already exceed all of 2025 (Bloomberg). | • Records at 'safe' names: Meta 5y at 108bp and Nvidia at 101bp (both records); Alphabet and Amazon at all-time peaks; Microsoft spreads up. | • Stress tiers: Oracle 322bp (144bp in January); SpaceX a record 226bp (110bp at its late-June CDS launch); CoreWeave ~1,090bp, with $1.82mn upfront plus $125k a quarter per $10mn. Above 1,000bp, recovery pricing 'starts to take over' (S&P's Nolan). | • Driver: AI-linked debt issuance of ~$466bn year to date, against $101bn a year earlier (Morgan Stanley), though borrowing has slowed since June. Concentrated risk and circular financing among OpenAI and Anthropic suppliers add a 'complexity premium'. | • Who is buying: bond investors hedging their books, plus multi-asset and equity managers using CDS as a cheaper hedge than equity puts, which adds to the price rise. | • Counterweight: Meta and Nvidia spreads (~100–110bp) remain low in absolute terms compared with Oracle, SpaceX and CoreWeave, and part of the move is hedging flow from non-credit investors rather than a default call by credit specialists.
What Financial Times may be missing
There are no gross or net notional-outstanding (e.g. DTCC) figures. The jump in weekly volume, a Morgan Stanley Research estimate for seven names, therefore can't be sized against the bonds outstanding or against past hedging spikes. Single-name CDS liquidity, bid-ask spreads and dealer concentration are not discussed, though they can exaggerate moves in thin markets, and neither is how much of the buying is basis or relative-value trading rather than outright hedging. There is no split between the companies' own bonds and off-balance-sheet project, lease or JV debt for data centres, where much of the risk may sit. The companies themselves give no view, and there is no free-cash-flow coverage maths, even though Kabra names FCF as the other key metric. Microsoft's spread level isn't given. The European angle is missing: nothing on European AI-infra borrowers such as Nebius, or on European banks' and private-credit funds' data-centre exposure.
