高利率撞上高杠杆：从今夜CPI到CoreWeave财报，AI牛市还能扛多久？
US October CPI will be released tonight at 21:30. The market expects headline and core month-over-month figures of 0.3% and 0.2%, respectively. Because no price data was collected during last October's shutdown, no official year-over-year reading will be published this time. Around 6 a.m. Beijing time tomorrow, CoreWeave will hold its Q3 earnings call. What the market really wants to see has shifted to another number: whether $860 million to $940 million in quarterly interest expense can be covered by $200 million to $260 million in adjusted operating income.
At 21:30 Beijing time tonight, CPI comes first. Around 6 a.m. Beijing time tomorrow, CoreWeave's earnings call will deliver its report card. What really matters is whether, once the two answers are put together, the valuation logic for AI assets will continue to tighten.
1. CPI Is Missing the Year-over-Year Figure; Tonight the Market Is Really Watching Core MoM
The biggest peculiarity of this CPI release is that it lacks the indicator the market is most familiar with: the year-over-year change.
In October 2025, the US federal government experienced a 43-day shutdown. The Bureau of Labor Statistics did not complete that month's CPI price collection and did not subsequently fill the gap. This October's CPI therefore lacks a real October 2025 baseline, and the BLS will not publish the 12-month year-over-year change for headline and core CPI. The latest official data for September remains headline CPI at 3.7% year over year and core CPI at 2.6% year over year. Tonight's report will move market pricing directly from the month-over-month data.
The market currently expects October headline CPI to rise 0.3% month over month and core CPI to rise 0.2%, a marked cooling from September's 0.6% and 0.3%. Falling gasoline prices will help slow headline CPI. For the Fed, what really matters remains core inflation excluding food and energy, especially whether housing, transportation services and other sticky services prices can continue to slow.
This is also where tonight's data could produce a disconnect: a figure below expectations does not necessarily mean interest-rate pressure has eased. A 0.2% core month-over-month reading is basically in line with expectations and may not be enough to loosen pricing for a December rate hike. What could truly drive a repricing in rates trading is core CPI clearly below 0.2%, or conversely a return above 0.3%. October nonfarm payrolls previously came in at 165,000, above market expectations, and a December rate hike has become the mainstream market pricing, with the latest market-implied probability at about 84% (CME data cited, November 9; 72.8% before the nonfarm payrolls release).
What tonight's CPI really affects is whether, beyond the December hike, the 2027 rate path can continue to be revised upward. Bank of America and Morgan Stanley currently expect one hike each in December and March, with a terminal rate of 4.25% to 4.5%. If core month-over-month is only 0.2% or even lower, long-end US Treasury yields, the dollar and high-valuation tech stocks all have room to catch their breath. If core inflation returns to 0.3% or higher, the market will again discuss keeping rates high for longer, and the AI sector is precisely one of the assets through which changes in funding costs transmit fastest.
In other words, CPI answers whether money is expensive. CoreWeave's earnings need to answer whether, even if money is expensive, AI infrastructure can still earn it back.
2. CoreWeave's Biggest Test Has Shifted from Revenue to Interest
CoreWeave's revenue growth can hardly remain the biggest suspense. The company reported Q2 revenue of $2.575 billion, up about 112.5% year over year. As of the end of June, revenue backlog stood at about $104 billion, and in early Q3 it added more than $25 billion in customer commitments. Active power capacity reached 1.5 GW, with contracted power capacity of about 3.7 GW. The demand-side story remains strong.
But what the market really cares about now is how much capital these orders will require to fulfill, and who bears the financing costs incurred before fulfillment.
The company's previous Q3 guidance was revenue of $3.45 billion to $3.6 billion, interest expense of $860 million to $940 million, and adjusted operating income of $200 million to $260 million. At the midpoint of the ranges, $900 million in interest corresponds to $230 million in adjusted operating income, or about 3.9x. That number alone is enough to illustrate the point: CoreWeave is in a phase of rapid revenue growth while financing costs simultaneously consume operating profit.
The actual Q2 data is even more direct. The company reported quarterly revenue of $2.575 billion, a GAAP operating loss of $49 million, and interest expense of $640 million. Adjusted operating income was $128 million, with interest nearly 5x that amount. Adjusted EBITDA reached $1.51 billion, which on the surface is enough to cover interest, but this does not solve the real problem: CoreWeave still needs to keep investing enormous capital to turn orders into computing power that can actually generate revenue.
This is also why looking only at EBITDA can easily understate risk. Q2 capital expenditure was about $9.4 billion, slightly above the upper end of guidance (disclosed on the company's earnings call). First-half capital expenditure was about $14.1 billion (cash flow statement), while operating cash flow over the same period was only about $3.66 billion. The company is capable of generating cash; it is just that the speed at which it generates cash is far behind the speed of capital required for expansion.
So the most worthwhile things to read in tomorrow morning's earnings report have shifted from revenue to three other things: where actual interest expense for the quarter lands, how much of the new capacity has come online and begun contributing revenue, and how prepared the company is to finance continued expansion in 2027.
The $104 billion order backlog is real, and 1.5 GW of active capacity is real, but orders are not cash, and capacity is not profit. Only if newly built data centers are delivered on schedule, customers pay according to contract, and operating cash flow begins to catch up with capital expenditure can CoreWeave's high leverage truly be called leverage.
3. Bonds Vote Before Stocks; What the Market Worries About Is the Financing Chain
Looking only at Monday's US stocks, it would be easy to conclude that last week's AI selloff is over. SOXX rose 7.49%, AMD rose 13.26%, Broadcom rose 8.78%, and CoreWeave rose 5.56%, a clear rebound after the selloff (market data interface, November 9 close).
But the signal from credit markets is not so optimistic: CoreWeave's 8.5% coupon dollar bonds maturing in 2032 had fallen to about 71 cents, down about 8.5 points in a single week. Unsecured bond yields have risen from around 10% previously to around 15%, and the five-year CDS spread has breached 1,100 basis points. This pricing is not saying that AI has no demand. It is saying that the market has begun to demand that AI infrastructure companies pay a higher price for high leverage, high capital expenditure and refinancing risk.
A more important signal is that this pressure is spreading to other parts of the industry chain. A recent Goldman Sachs credit market observation showed that the chip sector's CDS spread overtook that of large cloud providers for the first time in three months. The market previously tended to understand AI financing risk as cloud providers needing to borrow to build data centers. Now it is asking further: if cloud providers themselves control capital expenditure, how fast can Neocloud orders still grow? If financing costs continue to rise, will credit risk across chipmakers, data center operators and GPU clouds rise at the same time?
Microsoft's actions also make this question more concrete. According to a CNBC report on November 6, Microsoft is reassessing its list of Neocloud partners and tends to prioritize its own data center resources. Microsoft has not yet decided which supplier to eliminate, but it has abandoned a site with UK-based Nscale and did not renew related contracts in Texas.
This does not mean Microsoft is abandoning Neocloud, still less that AI demand has suddenly disappeared. The real change is that customers are beginning to examine more carefully than before the economics of buying compute from third parties versus building it themselves. For companies like CoreWeave, how large an order customers are willing to sign is one thing; whether orders can be delivered on schedule, whether customers will continue to add orders, and whether financing institutions are willing to provide funds for the next batch of data centers are another.
Therefore, the valuation logic for AI infrastructure is changing, with the focus shifting from how strong demand is to whether demand, financing and cash recovery can all hold at the same time.
4. After Tonight, What Should the AI Trade Watch?
Putting CPI and CoreWeave together, tonight is actually a very clear stress test, with outcomes falling roughly into four combinations.
CPI below expectations and CoreWeave's earnings steady is the most comfortable combination for AI assets. Core CPI below expectations would bring long-end yields down. If CoreWeave simultaneously reports lower interest expense, smoothly commissioned capacity and a clear financing arrangement, the market will again believe that high capital expenditure is only a temporary phenomenon of the expansion phase. Under such a combination, a continued rebound in CoreWeave, AMD, Broadcom, data centers and other high-beta AI assets cannot be ruled out.
CPI above expectations while CoreWeave's earnings remain steady: the market will begin to diverge. With rates still elevated, companies that truly have cash flow, customer quality and financing capacity may continue to attract capital, while the valuation recovery of highly leveraged Neoclouds will be constrained. The AI rally will not end because of this, but the strategy of buying the AI sector wholesale will become increasingly difficult, and the market will place more emphasis on who can truly convert orders into cash.
The real cause for caution is CPI above expectations while CoreWeave simultaneously exposes financing pressure. If core inflation returns to 0.3% or higher, long-end rates continue to rise, and CoreWeave's interest expense exceeds the upper end of guidance, capacity delivery is delayed, or management cannot give a sufficiently clear answer on 2027 financing arrangements, last week's AI selloff could exceed the scope of position clearing, and the valuation framework would begin to contract further.
Conversely, CPI below expectations but CoreWeave's earnings weak cannot simply be interpreted as broadly positive for the AI sector. Lower rates can ease valuation pressure, but they cannot solve the company's cash flow and debt problems. In this case, capital is more likely to rotate from highly leveraged AI infrastructure to AI beneficiaries with healthier balance sheets and stronger free cash flow.
This is also what is most worth watching tonight: CPI determines the cost of capital, and CoreWeave determines whether AI expansion can still hold at a high cost of capital. The former affects the valuation denominator for the entire market; the latter directly tests whether AI infrastructure companies' earnings and cash flow can cover this expansion model.
Monday's rebound shows that the market is willing to buy back AI assets that were sold off, but whether the rebound can turn into a trend recovery cannot be judged by stock prices alone. At 21:30 tonight, watch core CPI first; tomorrow morning, watch CoreWeave's interest, capacity and financing. For high-beta AI assets, these two sets of numbers together are more meaningful than a single earnings report or a single macroeconomic data point.
5. Final Thoughts: AI Demand Has Not Disappeared; What Is Expensive Is the Money to Pay for AI
What is most worth being alert to at CoreWeave right now is not that the $104 billion order backlog suddenly disappears, nor that AI demand is disproven. The real problem is that realizing revenue from AI infrastructure takes time, while debt interest and capital expenditure must be paid now.
Q2's $640 million in interest corresponded to $128 million in adjusted operating income, and the company's own Q3 guidance pushes that ratio to nearly 4x. First-half capital expenditure of about $14.1 billion corresponded to about $3.66 billion in operating cash flow. As long as capital expenditure continues to grow rapidly, the company will need to keep entering debt and equity financing markets. Once financing costs continue to rise, a valuation built on high growth will depend increasingly on whether cash flow can be smoothly realized in the coming years.
So tonight's reading is not just whether CPI is 0.2% or 0.3%, nor just CoreWeave's after-hours move. What really needs to be checked is whether the four variables of rates, interest, capacity and financing can all hold at the same time.
If CPI cools and CoreWeave's financing capacity remains stable, the AI trade may shift from last week's panic deleveraging back to fundamentals-driven trading. If CPI continues to come in above expectations while CoreWeave's financing pressure is further exposed, the market will need to reprice highly leveraged AI infrastructure.
This time, the market has to answer another, more realistic question: how much money does AI's prosperity actually need to continue?
