AI & Markets - David Groch
Two markets are now pricing two different revolutions.
The equity market is pricing demand, and on the evidence it is right. South Korea's September exports rose 83.5% year over year to a record $120.9 billion, with semiconductor shipments up 263% to more than $60 billion in a single month. That is not a narrative. That is customs data. Somebody is buying every chip Asia can make.
The credit market is pricing the bill, and on the evidence it is also right. Five-year credit default swaps hit records across the AI complex this month: Oracle at 322 basis points, up from 144 in January; Broadcom at 136; Nvidia at 101; Meta at 108; SpaceX at 226; CoreWeave near 1,090, which is distressed territory by any definition. Converted into the market's own arithmetic, Oracle's spread implies roughly a 23% five-year default probability, Broadcom's about 12%, Nvidia's about 8%. AI-linked companies have issued an estimated $466 billion of debt in 2026, against $101 billion in the same period of 2025. Weekly trading in CDS on the seven biggest AI names went from under $2 billion in July to over $9 billion in September.
One honest caveat before the calendar: an implied default probability is not a forecast. Part of the widening is mechanical, because equity managers buy CDS as a cheap hedge and hedging demand widens spreads on its own. Oracle is not going bankrupt at a 23% rate in any world a credit analyst would sign. What the spreads actually say is narrower and more useful: the price of insuring the buildout has multiplied, the marginal buyer of AI debt now demands to be paid for duration and doubt, and the next round of funding will not be priced like the last one. That is the story. And unlike most market stories, this one has dates.
Next week: the pincer
Monday, October 26. Celestica reports after the close, with its investor day on Tuesday. This is the margin canary. Celestica is a contract manufacturer with thin EMS margins and enormous hyperscaler exposure, and the one serious bear case on the name is simple: when AI hardware margins compress, they compress for the assembler first. The Street is unanimously bullish (average target near $474 against a $262 stock), which means the print has to be clean, not good. A margin wobble here is the first company-level confirmation that the buildout's economics are squeezing the supply chain. The same morning, the first big SpaceX lockup tranche (up to 328 million shares) becomes tradable, a week after the stock rose 8% on earnings and fell 9% on profit-taking and unlock fears. Supply meets a story stock.
Wednesday, October 28. The week's hinge, and it is a pincer. At 2:00 p.m. ET the FOMC decides. The Reuters poll of 100 economists is as close to unanimous as polls get: 94 expect a hold at 3.75% to 4.00%, and all 100 expect a hike in December. The risk is not the decision, it is the language, because Chair Warsh has dropped forward guidance and publicly distanced himself from the committee's own projections. Two hours later, Microsoft and Alphabet report. Their earnings are no longer really about earnings. Meta already showed the template: beat on revenue, guide above consensus, and lose 7% anyway because the capex line moved. What Microsoft and Alphabet say about 2027 spending is the referendum on whether Meta's repricing was one company's problem or the sector's.
Thursday, October 29. September PCE and the first Q3 GDP print land before the open (consensus: core PCE 3.1% year over year, headline 3.6%), and Amazon reports after the close. A hot core print with a December hike already unanimous is the stagflation-lite combination: it validates the CDS move and pushes the terminal-rate debate from one more hike to two. A soft print is the only scheduled event all week that can actually relieve the credit market.
Next month: the report cards
November 3 brings the US midterms, which matter here for one reason: energy and industrial policy are now market variables, and oil above $110 with the Strategic Petroleum Reserve at its lowest since 1982 (282.7 million barrels) is a political fact as much as an economic one.
November 2 to 12 is the cluster that decides whether the CDS story stays a hedge or becomes a verdict. The leveraged end of the buildout reports in a ten-day window: Cipher Mining on November 2, Core Scientific on November 5, CoreWeave around November 9, Nebius around November 10, TeraWulf in the same stretch. Read these reports for one line only: the funding line. Bank of America's preview of CoreWeave is the template of the whole moment. The bank rates the stock a buy with a $140 target, forecasts Q3 revenue of $3.66 billion (up 168%), cites a $129 billion backlog, and then estimates the company needs roughly $20 billion of additional funding, with $12.5 billion of capex in the quarter alone. Even the bull case is now written as a financing story. Backlog is not the question anymore. The coupon is.
November 18 is Nvidia, the last and largest report of the season, and throughout the month Meta's $25 billion New Mexico judgment accrues interest at 15% a year, roughly $10 million a day, which is its own kind of calendar: every week of appeal is a week the settlement price argument changes.
Just past the horizon, December holds the two dates that could close the loop: the FOMC meeting where 100 of 100 economists expect the hike, and December 9, when Micron's $35 billion buyback authorization becomes usable. The largest memory maker becoming a structural buyer of its own stock is the equity market's best scheduled answer to the credit market's question.
Three ways this resolves
The bill gets paid quietly. Microsoft, Alphabet and Amazon hold or trim their capex guides to something the cash flow can carry, the neoclouds fund at tolerable rates, and CDS spreads tighten into year-end. Signpost: Oracle CDS back under 250 basis points and a CoreWeave funding deal at single-digit rates. In this world the October repricing was a tantrum.
The slow bleed. Guides go up again, the Fed hikes in December with two more on the table, and equities de-rate gradually toward where credit already is. No crash, no capitulation, just a multiple that shrinks while the spending does not. Signpost: bank stocks, already on their longest losing streak since 2008 (six straight weeks for the KBW index), keep sliding while the indexes hold up on a narrowing group of names.
Something breaks at the weak end. A funding deal fails, or prices at the mid-teens yields where CoreWeave's bonds already flirt, and the question stops being about one neocloud's balance sheet and becomes about who else financed the same way. Signpost: any postponement or pulled deal in the November cluster, or CoreWeave CDS pushing through 1,200 basis points. This is the only scenario where the Asia story and the credit story collide, because the chip demand is real, and real demand financed badly is exactly how the last buildout ended: the fiber got lit, the carriers did not survive it, and the cables outlived the companies that laid them.
The demand is not the debate. The price of money is. And for once, the market has published the schedule on which it will argue: October 28 for rates, October 28 and 29 for capex, November 2 to 12 for the leveraged end, December for the bill itself. Watch the calendar, not the commentary.
