The cost to protect against a debt default at Amazon, Alphabet, Microsoft, Meta and Oracle widened over the past month to the highest levels going back to 2021, The Wall Street Journal reported on 1 November, citing the bond data provider Solve.
“There were no exceptions, suggesting broad market concern about the sector rather than idiosyncratic credit events at individual companies,” Solve co-founder Eugene Grinberg told the Journal. By our arithmetic, the hedges the story describes on CoreWeave shares and Nvidia B300 rental prices pay out only after falls of about 36% and 47%.
Short explainer · Big Tech debt insurance at highest since 2021
A vertical news Short summarising this story. Figures come from The Wall Street Journal, citing Solve, Cboe and Silicon Data; our arithmetic is labelled.
Business Pill · Financial Conditions
A short explainer on financial conditions: how credit spreads and borrowing costs feed through the economy. It teaches the general idea only and says nothing about the companies in this piece.
The key insight: As we read the report, default protection on all five hyperscalers reached its highest since 2021 with no exceptions, according to Solve, and the same story shows hedges reaching CoreWeave shares and the hourly rental price of Nvidia B300 chips.
The Journal reported that “the recalibration in Oracle credit-default spreads was especially stark, widening by more than 1 percentage point” over the past month. It did not give spread levels for the five companies.
For context, the Financial Times reported on 20 October that Oracle’s CDS was quoted at 322 basis points that Monday, up from 144 at the start of the year, as we reported. By our arithmetic, that is 178 basis points wider, or about 2.2 times, in under ten months. Reuters had reported a then-record 288 basis points on 15 October, citing S&P Global Market Intelligence.
CoreWeave shares at around $55 vs the $35 level at which popular 2028 put options pay out, and the Silicon Data B300 rental index at $7.56 an hour vs the $4 level in Jump Trading’s example, as reported by The Wall Street Journal on 1 November 2026; the falls of about 36% and 47% and the implied start-of-year level of about $4.85 are our arithmetic.
Hedges on CoreWeave Shares
Put option contracts tied to CoreWeave “surged to the highest level on record this month and have stayed elevated”, Cboe Global Markets data show, according to the Journal.
The paper said some of the most popular CoreWeave bets have been put options expiring in 2028 that pay out “if the shares plunged to $35”, with the shares at around $55 this week. By our arithmetic, that is a fall of about 36% before those puts pay out at expiry.
A Market for Hedging Compute Prices
The cost to rent Nvidia B300 chips has risen around 56% this year to $7.56 an hour, according to a Silicon Data index cited by the Journal. By our arithmetic, that puts the index at about $4.85 at the start of the year.
Quant firm Jump Trading recently launched a trading desk for computing power, the paper reported. In October, Bloomberg reported that Jump had hired the founding team of Ito, a startup that trades access to computing power, as we covered. In the Journal’s example, Jump could agree to buy if B300 prices fell to $4 an hour: by our arithmetic about 47% below the current index and about 17% below its implied level at the start of the year.
“People are drilling deeper into the economic models,” said Dave Olsen, president of Jump. Susquehanna International Group has fielded interest from data centers and privately held neoclouds seeking to hedge their exposure to chips, said Nick Volbi, its head of institutional prediction markets.
The Business Lever: Pricing the Downside of the Build-Out
As we read the report, the hedging is reaching three layers at once: the debt of the five biggest spenders, the shares of a heavy borrower such as CoreWeave, and the hourly rental price of the chips that lenders finance.
As we read the Oracle figures, the Journal reports a spread more than 1 percentage point wider over the past month; separately, the FT reported on 20 October that Oracle’s CDS was quoted at 322 basis points on Monday 19 October, against 144 at the start of the year.
As we read the CoreWeave options, the popular 2028 puts pay out only below $35, about 36% under the roughly $55 share price, by our arithmetic.
As we read the compute example, Jump’s $4 an hour level sits about 47% below the $7.56 index and about 17% below its implied level at the start of the year, by our arithmetic.

Three Implications
FOR HYPERSCALER BONDHOLDERS The Journal reported that default protection on Amazon, Alphabet, Microsoft, Meta and Oracle widened to the highest levels going back to 2021, according to Solve.
FOR NEOCLOUDS AND THEIR LENDERS Susquehanna’s Nick Volbi described compute put options as a form of insurance that a borrower could show a lender when asking for financing.
FOR COMPUTE PRICES The Journal cited a Silicon Data index putting B300 rent at $7.56 an hour, up around 56% this year, and reported that Jump Trading has launched a compute trading desk.
The framework says “It is a sovereign-scale financing problem dressed in tech-company clothing โ and the financial architecture is starting to invert.”
As we read it, the price of default protection on the biggest spenders is one place where that financing problem shows up. The framework predates the Journal report and does not discuss these spreads.
The Journal does not give the spread levels for the five companies, the size of the CoreWeave put positions, or the volume Jump or Susquehanna has traded. Olsen said hedging strategies as a whole are still dwarfed by the AI trade. The 36%, 47%, 17%, $4.85 and 2.2 times figures are our arithmetic.
This Week In The AI Supercycle
Anthropic’s Reality Check, The Capital Squeeze, & The New World Order
This week’s issue: for two years the AI build-out was priced as a growthstory. This week it started being priced as a credit story.
Default protection on all five hyperscalers is at its highest since 2021, according to Solve via the Journal, with Oracle’s spread more than 1 percentage point wider in a month. The CoreWeave puts and the B300 compute hedge in the same story pay out only after falls of about 36% and 47%, by our arithmetic.
A note on sourcing. The credit, options and compute-hedging details and all quotations come from The Wall Street Journal article by Gunjan Banerji of 1 November 2026, which we read in full in a verbatim repost because the Journal blocks our reader; the Journal cites Solve, Cboe Global Markets and Silicon Data, whose data we did not see. The FT and Reuters Oracle levels come from our earlier reporting. The 36%, 47%, 17%, $4.85, 178-basis-point and 2.2-times figures are our arithmetic.
