• CoreWeave shares plunge amid debt concerns: The stock has fallen more than 22% in a week and over 60% from its all-time high, as investors question the sustainability of the company's debt-driven expansion.
• Soaring borrowing costs raise financial risks: With debt exposure estimated at $50 billion and some bond yields exceeding 15–16%, CoreWeave faces growing refinancing challenges despite its $104 billion backlog of contracted future revenue.
• CoreWeave's troubles highlight broader risks in the AI boom: Rising financing costs and massive infrastructure investments are raising concerns about profitability across the AI sector, as investors increasingly question whether future revenues can justify today's enormous capital expenditures.

Shares of CoreWeave, a US-based provider of cloud infrastructure for artificial intelligence, have come under significant pressure. Investors are increasingly concerned that the company's heavy debt burden and rising financing costs could hamper further expansion of its data centers. Despite strong demand for computing power, the market is beginning to question the viability of an expansion strategy heavily dependent on borrowed capital.

CoreWeave Shares Plunge as Investors Question the Company's Financial Health

CoreWeave shares are experiencing one of their most difficult weeks since the company's stock market debut in March 2025. During the first three trading sessions of the week, the stock lost approximately 20% of its value, including a decline of more than 15% on Wednesday. Thursday's 5.9% rebound provided only temporary relief. On Friday, October 16, the shares came under renewed pressure, falling more than 8% in early trading.

As a result, the weekly decline exceeded 22%, putting CoreWeave on track for its worst weekly performance in more than 11 months. The scale of the sell-off becomes even more apparent when viewed over a longer period. Since reaching an all-time high in June 2025, CoreWeave shares have lost more than 60% of their value. Despite this steep correction, the stock remained above its initial public offering price.

Investor concerns, however, extend beyond the equity market. Even more troubling warning signs are emerging in the bond market, where a sharp increase in yields reflects a deteriorating assessment of the company's creditworthiness.

Rising borrowing costs become CoreWeave's biggest threat

CoreWeave's business model relies on substantial investments in data centers equipped with advanced graphics processing units (GPUs) used to train and run artificial intelligence models. Expanding this infrastructure requires enormous capital expenditures, which the company finances to a significant extent through loans and bond issuances. According to Reuters, CoreWeave's total debt exposure amounts to approximately $50 billion. In recent days, yields on some of the company's bonds have exceeded 15–16%, reaching levels typically associated with debt issued by companies facing severe financial stress.

Even more alarming signals have emerged from the credit default swap (CDS) market, where investors can purchase protection against a borrower's default. On Thursday, CDS prices implied a market-estimated probability of CoreWeave defaulting on its obligations within five years of more than 60%. This figure does not mean that the company's bankruptcy is inevitable. It represents a model-based assessment of credit risk that depends, among other factors, on CDS prices and the assumptions used in the calculations. Nevertheless, it illustrates how sharply investor perceptions of CoreWeave have deteriorated.

The broader macroeconomic environment is adding to these challenges. Higher-than-expected inflation in the United States has heightened concerns about further interest rate increases and, consequently, rising costs of raising capital. For a company that needs billions of additional dollars to expand its infrastructure, maintaining access to financing on acceptable terms is essential. Rising bond yields in the secondary market do not automatically increase interest payments on all existing debt, but they can translate into significantly higher costs for new debt issuances and refinancing.

Nvidia seeks to reassure investors

CoreWeave works with some of the world's largest companies developing artificial intelligence, including Microsoft, OpenAI, and Meta. Its backlog of contracted future revenue stands at approximately $104 billion, providing the company with considerable visibility into future sales.

Jensen Huang, CEO of Nvidia, which is both a shareholder and a key technology supplier to CoreWeave, has also sought to reinforce confidence in the company. Huang maintains that CoreWeave's financial position is steadily improving and that the company does not require emergency financial support from Nvidia. In his assessment, CoreWeave's cost of capital is actually declining.

These reassurances contrast sharply with signals from the bond market, where investors are demanding increasingly high risk premiums. This highlights the divergence between the assessment of CoreWeave's prospects by its business partners and the concerns of financial market participants.

Sell-Off spreads across the AI sector as concerns over investment returns grow

CoreWeave's difficulties are part of a broader wave of selling among artificial intelligence-related stocks. The Philadelphia Semiconductor Index (SOX), which tracks semiconductor companies, was down nearly 10% for the week. Shares of Dell and Hewlett Packard Enterprise also came under pressure, along with those of other companies involved in developing data center infrastructure.

The shift in sentiment suggests that investors are beginning to focus not only on revenue growth but also on the costs and sources of financing for future investments.

Until recently, enormous demand for AI infrastructure allowed many companies to justify exceptionally high capital expenditures based on expectations of future profits. However, as capital becomes more expensive, this approach is becoming increasingly risky.

The investment cycle associated with artificial intelligence is still in its early stages. Rising interest rates could make it more difficult to finance new projects, but they are unlikely to halt the long-term growth in demand for computing power.

The key question, however, is whether future corporate revenues will be sufficient to justify the scale of current spending and enable companies to service their debt obligations on schedule.

CoreWeave exposes one of the biggest risks of the Artificial Intelligence boom

CoreWeave's situation highlights one of the most significant challenges associated with the rapid expansion of artificial intelligence infrastructure. Even companies operating in markets with exceptionally strong demand can face financial pressure if the costs of expansion and debt servicing rise faster than their ability to generate cash. CoreWeave has a substantial backlog of contracts and maintains relationships with some of the technology industry's largest players. However, this does not eliminate the risks associated with financing further investments before the infrastructure being built begins generating its full expected revenue.

CoreWeave's most pressing challenge is no longer simply attracting customers. It is sustaining a growth model in which future cash inflows must cover enormous current capital expenditures as well as the costs of servicing debt. The company's future prospects will depend on its ability to convert contracted orders into actual cash flow, maintain access to financing, and reduce credit risk. CoreWeave's situation could also serve as an important test for the entire artificial intelligence sector. It demonstrates that even sustained strong demand for AI technologies does not guarantee success for companies whose continued expansion requires ever-increasing levels of debt.

• Persistent core inflation strengthens the case for further Fed tightening.
• December appears the more likely timing for another US rate increase.
• Hawkish ECB comments also point towards another hike before year-end.
• EUR/USD may depend on differences in the expected scale of tightening.

Persistent inflation is strengthening the case for further monetary tightening in both the United States and the euro area. December remains the more likely timing for the next rate increases, although the October meetings could provide clearer signals about future decisions.

September’s US data showed that price pressures extend beyond rising energy costs. Core CPI inflation exceeded forecasts, with its annual rate increasing by 0.2 percentage points to 2.6%. Having stood at 2.5% at the beginning of the year, it shows little evidence of sustained progress towards lower inflation.

The Fed’s preferred inflation measure, the personal consumption expenditures price index, paints a similar picture. Core PCE inflation remains close to its level at the start of the year, at 3%, above the corresponding CPI measure.

The dollar initially strengthened following the release of the latest inflation data, pushing EUR/USD close to 1.11. The pair subsequently rebounded sharply, moving back above 1.12. Such a swift reversal of the dollar’s gains may suggest that future rate hikes are already largely priced in. It could also signal scope for an upward correction in EUR/USD in the near term, particularly as no meaningful technical rebound has emerged since the latest downward move began.

For the Federal Reserve, the inflation trend is crucial, and it still offers insufficient grounds to end the tightening cycle. Kevin Warsh emphasises that decisions should reflect the broader economic picture rather than individual data releases.

However, core inflation holding at elevated levels suggests that the tightening delivered so far may be insufficient to restore price stability. A late October increase, shortly before the congressional elections, appears less likely, while December looks like the more probable window for another move.

Increasingly hawkish signals are also emerging from the European Central Bank’s policy debate. Former Dutch central bank governor Klaas Knot argues that economic and geopolitical changes may require a moderate tightening bias.

Pierre Wunsch believes another rate increase will probably be necessary. Gediminas Simkus has expressed a similar view, saying that the case for a more restrictive monetary policy stance has strengthened since September.

Simkus highlights the importance of the December meeting, when policymakers will have a broader set of data available, while also stressing the relevance of the October meeting. These comments reinforce expectations of one more ECB rate increase this year, most likely in December.

With rate increases potentially approaching on both sides of the Atlantic, hawkish Fed rhetoric alone may not give the dollar a lasting advantage. What matters more is which central bank signals a need for greater cumulative tightening.

If expectations for the Fed and the ECB move in the same direction, the impact of monetary policy on EUR/USD could remain limited.

• Dow Jones turns outperformer: DJIA gained 2.46% in October through 15 October, beating the Nasdaq 100 (-1.86%) by 4.32 percentage points.
• AI rotation drives Dow strength: Investors shift toward healthcare and consumer stocks as AI financing concerns and semiconductor weakness weigh on the Nasdaq-100.
• Bullish breakout targets 53,100: US Wall Street 30 CFD holds above 51,950 pivotal support; a break above 52,390 could expose 52,687 and 53,100.

The Dow Jones Industrial Average (DJIA) has undergone a shift in performance over the past six weeks, from a laggard to an outperformer among major US benchmark stock indices.

In September 2026, the DJIA recorded a monthly loss of 3.53%, underperforming the S&P 500 (+0.26%) and the high-flying Nasdaq 100 (+4.58%), driven by AI-linked semiconductor stocks, with the PHLX Semiconductor Index surging 11.87% (see Fig. 1).

In contrast, from the start of October 2026 through Thursday, 15 October 2026, the DJIA reversed higher and recorded a gain of 2.46%, outperforming the tech-centric Nasdaq 100 (-1.86%) by 4.32 percentage points, heavily triggered by the weakness seen in the PHLX Semiconductor Index, which shed 9.73% amid fears of elevated AI optimism (see Fig. 2).

The DJIA’s October recovery has gained traction this week, with a clearer rotation towards healthcare and consumer stocks as the AI trade comes under pressure. Through Thursday, 15 October 2026, after the close of the US session, the Dow gained 1.0% for the week to 52,183, while the S&P 500 and Nasdaq 100 declined 0.9% and 3.1%, respectively.

The drivers of recovery have shifted since early October. The primary driver of the current Dow’s outperformance is rotation away from debt-sensitive AI infrastructure stocks towards businesses with more established earnings.

Concerns over AI financing costs intensified, while TSMC’s cautious 2027 commentary tempered enthusiasm despite another record quarterly profit. The Philadelphia Semiconductor Index fell for a seventh consecutive session on Thursday, 15 October 2026.

Healthcare and consumer stocks attracted buying, helping the Dow outperform its technology-heavy peers. This suggests its relative strength increasingly reflects a change in market leadership.

UnitedHealth has provided company-specific support. Its third-quarter earnings beat expectations, management raised its outlook, and comments pointed to tentative moderation in government healthcare programme costs. That gives the Dow’s healthcare exposure a fundamental earnings catalyst alongside the broader rotation.

The macro backdrop also remains difficult. September core CPI continued its climb to 2.7% year-on-year, while core CPI rose 0.3% month-on-month; both came in above the 2.5% and 0.2% forecasts, respectively.

Following Wednesday’s release, October’s Fed rate-hike expectations increased to around 30%, from approximately 20% according to the CME FedWatch tool.

The Dow’s resilience despite this repricing strengthens the rotation argument, but persistent inflation remains a threat to valuations and consumer demand.

The near-term view is more constructive on the Dow’s relative performance. Sustained healthcare and consumer leadership, followed by improving participation from financials and industrials, would strengthen the bullish catch-up case.

If leadership remains concentrated while inflation and financing costs rise, the Dow could continue outperforming the Nasdaq 100.

Let us now focus on the near-term technicals on the US Wall Street 30 CFD (a proxy of the Dow Jones Industrial Average futures).

The current price action in the US Wall Street 30, as of Friday’s Asia session on 16 October, has staged a significant bullish breakout from a medium-term (multi-month) descending channel, with resistance running from the current all-time intraday high set on 5 August 2026 (see Fig. 3).

Prior to the current descending channel’s bullish breakout, its price action shaped a bullish breakout above its 20-day moving average last Friday, 9 October 2026, and it retested and reversed bullishly on the 20-day moving average on Thursday, 15 October.

These observations suggest that the prior medium-term corrective decline phase of 7.65% from the 5 August 2026 all-time intraday high to the 1 October 2026 low is likely to have ended, with the US Wall Street 30 now undergoing a potential fresh bullish impulsive up move sequence.

Watch the 51,950 key short-term pivotal support to maintain the bullish momentum. A break above the 52,390 near-term resistance (also near the 50-day moving average) targets the next intermediate resistances at 52,687 and 53,100.

However, a failure to hold and an hourly close below 51,950 negates the bullish tone, suggesting a potential minor corrective decline to retest the 20-day moving average, which confluences with the next intermediate support at 51,550.
