Investors rush to insure against an AI blow-up: CDS trading on Big Tech debt jumps to $9bn a week, with Meta and Nvidia at record spreads
What's going on? Investors are buying credit default swaps (CDS), the insurance-like contracts that pay out if a borrower defaults, on AI-linked companies at a record pace, the Financial Times reported on 20 October. More than $9bn of CDS tied to bonds issued by Oracle, SpaceX, Alphabet, Amazon, Meta, Broadcom and Nvidia changed hands on average each week in September, up from less than $2bn in July, according to Morgan Stanley Research. US corporate CDS index volumes this year have already overtaken last year's total, according to Bloomberg data.
The price of protection: Five-year CDS on Meta hit a record 108 basis points this month, meaning it costs $108,000 a year to insure $10mn of Meta debt, and Nvidia hit a record 101bp. Protection on Alphabet and Amazon is also at all-time highs. Oracle was quoted at 322bp on Monday, up from 144bp at the start of the year, and SpaceX at a record 226bp, up from 110bp when its CDS started trading in late June. CoreWeave is in a different league at about 1,090bp, distressed territory: $10mn of protection now costs $1.82mn upfront plus $125,000 a quarter.
The bigger story: the AI build-out now runs on debt, so the credit market gets a vote. AI-linked companies have raised an estimated $466bn of debt so far in 2026, against $101bn in the same period of 2025, according to Morgan Stanley. The buyers of protection are no longer just bond investors. Multi-asset and equity managers now use CDS as a cheap hedge against their tech exposure, which pushes prices to records even for companies nobody expects to default. "CDS has become a key bellwether of investor sentiment towards hyperscaler funding and the broader AI trade," said Société Générale's Manish Kabra. S&P Global Market Intelligence's Gavan Nolan described "a complexity premium" for the sector's interlinked financing, and investors told the FT they are trading CDS on companies that supply computing to OpenAI and Anthropic, such as Oracle and Alphabet. The result is a three-tier market: neoclouds priced close to distress, Oracle in the middle (economist David Rosenberg calls it the "canary in the coal mine"), and the megacaps still low but drifting higher.
What's confirmed and what isn't: The volume and spread figures come from Morgan Stanley Research, Bloomberg, S&P Global and LSEG data, as reported by the FT, Reuters and CNBC. A wider spread is the market price of a hedge, not a forecast that a company will default. Part of the volume is lenders protecting loans they already hold, and Bloomberg has reported that the sheer volume of AI debt, more than any weakening in the megacaps' finances, is behind much of the move. For the riskiest name the signal is starker: Reuters calculated that CoreWeave's spread above 1,000bp implies about a 64% chance of default within five years, up from about 30% a year earlier.
Why it matters: The cost of capital for the AI build-out is now set as much in credit markets as in venture rounds. When protection on Meta and Nvidia trades at records, lenders get more selective about neoclouds, data-centre developers and the long compute contracts behind the labs, and new deals pay more. Semafor reported last week that a debt deal for Volta Infrastructure faltered as investors demanded higher yields.
