- CoreWeave debt concerns : AI demand is strong , but can the data centre major cash flow justify its spending ? Explained
Investor concern over debt financing for AI infrastructure is spreading into tech stocks. CoreWeave shares fell 15.5% on Wednesday, then recovered to close 5.94% higher on Thursday, while Nebius and Iren also came under pressure. Investors are questioning whether CoreWeave can generate enough operating cash flow to fund heavy chip and data centre spending, given its heavily negative free cash flow. CEO Mike Intrator said the backlog more than supports all debt obligations, and Deutsche Bank said it exceeds $100 billion, with about two-thirds from investment-grade customers, reiterating its buy rating. Oracle's five-year CDS spread reached 282 basis points, a roughly 10% rise in one week, and a CDS spread around 1,000 basis points is generally seen as a sign of credit distress.
- Why CoreWeave's troubles are rattling the AI boom
CoreWeave, which rents out computing power built on Nvidia chips to AI developers including Microsoft and OpenAI, carries about $50 billion in debt according to LSEG data and has never turned a profit. Yields on its 2031 bonds, rated junk, have jumped to about 16%, and the cost of insuring its debt against default has climbed to about 1,000 basis points. Analysts expect nearly $13 billion in revenue and a $2.13 billion loss this year, while the company raised its annual capex forecast to between $35 billion and $39 billion. CEO Mike Intrator said its $104.2 billion revenue backlog more than covers its debt obligations, and Nvidia has agreed to buy unsold capacity through April 2032. Gartner estimates about 80% of neoclouds could shut down by 2030, and rivals Nebius, Applied Digital and Iren have fallen in the recent selloff.
- AI Debt Warning Signs Are Piling Up : Why Bond Markets Are Getting Nervous About AI Infrastructure Spending
The cost to insure CoreWeave debt against default, measured by five-year CDS, hit a record of about 1,195 basis points, meaning $119,500 a year to insure $1 million of debt, while its October 2031 bond yield reached 16% and some bonds traded near 80% of face value. Oracle's five-year CDS neared 300 basis points, also a record, after S&P Global cut its rating to just one notch above junk. Bonds tied to Meta's Hyperion data-center project fell to around 91 cents on the dollar, and SoftBank's five-year CDS rose 24 basis points to 424. The pressure reflects a harsher macro backdrop, with oil prices climbing, inflation fears rising, and the 10-year Treasury yielding roughly 5%, while AI projects still face uncertainty over whether their revenue will cover heavy spending.
- CoreWeave shares, bonds headed for steep weekly losses as AI borrowing concerns mount
CoreWeave shares dipped 4.1% in premarket trading on Friday after jumping 5.9% in the previous session, and were down more than 15% for the week, on course for their biggest weekly decline in about two months. Its October 2031 dollar bond briefly yielded over 16% on Thursday and is set for a fifth straight weekly decline, while the cost of insuring its debt surged past 1,000 bps to record highs, according to S&P Global Market Intelligence data. The loss-making cloud company, which has about $50 billion in debt, has been hit as hot inflation data raised borrowing-cost worries, and BCA Research said its business model is a highly indebted bet on future data center demand. Shares of rival Nebius Group fell 1.5% on Friday morning.
- CoreWeave Stock Wipeout Exposes Divide Between AI Fear and Greed
CoreWeave shares fell 20% in the first three sessions of the week, including more than 15% on Wednesday, as its bonds slid to levels typically seen in distress amid rising Treasury yields. Credit default swaps on its bonds reached a record intraday high, pricing in more than a 60% chance of default within five years. The stock recovered to close up 5.9% on Thursday after Nvidia CEO Jensen Huang expressed confidence and Deutsche Bank called the selloff a buying opportunity. Still, the shares are down 62% from their June 2025 peak, and the article notes the company's heavy reliance on high-yield debt makes it one of the riskiest stocks in the AI trade.
- Jim Cramer Calls CoreWeave the "Real Deal," but the Stock Crashed 15% the Very Next Day. Should You Buy the Dip?
Jim Cramer called CoreWeave (CRWV) the “real deal” on Mad Money, but the stock fell about 15% less than 24 hours later, on Oct. 14. The immediate catalyst was an essay by Chamath Palihapitiya noting that CoreWeave’s $1.25 billion bond due 2032 briefly yielded 15% in the secondary market, versus 9.6% at issue in June. Investors are worried about debt, which stood at about $35.1 billion at the end of Q2 2026, or $51.6 billion including leases. In the first half of 2026, operating cash flow was about $3.7 billion against $6.2 billion in principal and interest payments, and consensus expects negative free cash flow of $25 billion in 2026. The author considers the stock too speculative for most long-term investors and would not rush to buy the dip.

- Irish central bank fines Coinbase Ireland $3.6 million over fund safeguarding failures
Ireland's central bank fined Coinbase Ireland 3.25 million euros ($3.6 million) for alleged failures to safeguard customer funds and oversee outsourced services, saying the unit relied excessively on its U.S. parent and lacked adequate systems and controls. The regulator cited a 2023 episode in which Coinbase directed 30 customers to deposit funds into an alternate account at another U.S. bank when Silvergate neared collapse, holding them alongside funds of another Coinbase entity's customers, and coding errors left a safeguarding account underfunded by an average of 0.54% in 2023 and the first half of 2024. Coinbase said no customer lost money or was unable to access funds. The penalty follows a 21.4 million-euro fine on Coinbase Europe in 2025 for anti-money laundering failures.
- XRP Is 63% Below Its All-Time High and Ethereum 51%. Which Reclaims their ATH First?
XRP trades at $1.33, 63.5% below its all-time high of $3.65 set in July 2025, while Ethereum is at $2,403, 51.4% below its August 2025 peak of $4,946, and both fell over the past month. Reclaiming those highs would require gains of 174.4% for XRP and 105.9% for Ethereum, and the article concludes Ethereum has the edge, citing JPM Coin's integration onto its network on October 19 and a sizeable ETF asset base. XRP ETFs held $1.57 billion in net assets, but inflows slowed to $708,500 on October 21, while Ethereum's cumulative ETF net inflows fell to $12.83 billion amid outflows. Other news includes Germany's Sparkassen savings banks offering XRP trading and Ethereum's Glamsterdam upgrade entering the Hoodi test network on October 26.
- Tech stocks fall as Nvidia boss warns of AI funding slowdown
US stocks fell sharply on Thursday after Nvidia CEO Jensen Huang warned that a “scarcity of capital” was holding back AI rollout, fuelling worries about the cost of sustaining the AI boom. The Nasdaq 100 dropped 1.5% and the S&P fell nearly 1%. Meta shares slid 5% after it raised the lower bound of its capex guidance from $130 billion to $135 billion and issued new non-voting stock, while Tesla fell 2% after cutting its proposed AI spending from $25 billion to $20 billion. Oil added to the sell-off, with Brent rising 2.5% to $111.60 per barrel, its first move above $110 since May, after Aramco evacuated staff from its Dhahran headquarters over a warning of Houthi attacks.
- Musk: People Are "Buying FSD With a Car Attached." There's Only One Problem.
Tesla said 75% of its new North American deliveries in the third quarter came with an FSD subscription, up from 55% in the second quarter, and active FSD subscriptions rose 67% to 1.74 million. Tesla has not disclosed how many subscribers pay, since the first month is free. When an RBC analyst asked whether the paid rate was closer to 30% to 40%, CFO Vaibhav Taneja did not give a clear answer. The article also notes that Tesla's overall gross margin fell from 25.6% in fiscal 2022 to 18% in fiscal 2025, while the stock trades at 185x forward earnings. It argues the paid attach rate is the key figure to watch, as paid FSD revenue remains small relative to Tesla's total sales.
- Producer of 'Say Hi' Shows to Be Listed on HoSE

This year, DatVietVAC targets revenue of 3,382 billion dong and after-tax profit of 420 billion dong, growth of about 6% and 11%.
- TeraFab's $16.8 billion bet to start producing 100K chips a month
Host Ejaaz Ahamadeen comments on Elon Musk's proposed $16.8 billion investment in his TeraFab semiconductor manufacturing project. He argues that chips are a key bottleneck for AI, humanoid robots and cars, and that vertical integration would reduce reliance on suppliers such as Nvidia. The first phase involves $16.8 billion to reach 100,000 wafers a month before 2030, with a peak of 1 million wafers a month within 10 years and more than 3,000 jobs. The host also stresses that the project carries many potential risks.
