Quick Summary

The article reports on the recent financial instability affecting companies in the neocloud sector, which provide computing power for AI training. Specifically, it highlights CoreWeave's significant share price drop by 15% and rising bond yields to 15%, along with similar issues facing other firms like Firmus. The piece argues that these problems stem from circular financing practices where companies rely heavily on long-term commitments from tech giants but face risks due to rapidly evolving GPU technology and market uncertainties around AI's future demand.

Story summary

Tech and AI-related stocks experienced significant sell-offs starting Friday, October 16, 2026, with fears mounting over debt-fueled spending on infrastructure. The Nasdaq and S&P 500 indices fell by 2.4% and 1.3%, respectively, setting the week for their worst performance since June. Shares of SanDisk, AMD, and Micron dropped by 6.7%, 5.9%, and 5.7%, while CoreWeave, an AI cloud provider, plummeted by 25% over five days. This sell-off reflects a growing crisis of confidence due to concerns about unrealistic valuations and the impact of rising interest rates on future profitability. Additionally, Firmus, an Australian data center operator, cancelled its planned $44 billion IPO after investors rejected high valuations based on speculative revenue projections, further indicating the fragility of the AI sector's financial foundations.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.

🔮 Given that the core issue in the election is affordability, the headline rise in the rate in September of 0.6 per cent – a material increase on the 0.4 per cent rise in August – and the year-on-year increase in prices of 3.7 per cent (3.4 per cent previously) couldn’t have come at a worse time for Donald Trump and the Republicans.
🔮 What would it look like if demand for government and corporate debt rose rapidly even as its cost surged?
🔮 When the latest inflation data is released on Wednesday morning in the US, it is expected to show that the inflation rate in the world’s largest economy rose again in September, adding to the cost-of-living pressures that are the key issue in the midterms.
🔮 Donald Trump announced a deal last Friday under which Russia will supply the US and the global market with diesel that Russia may not have and America doesn’t need.
🔮 A delegation of European Union trade negotiators is in Beijing, hoping to avert what could be a full-scale trade confrontation with China.
🔮 The equal weight index has risen 10.8 per cent this year and has actually fallen almost 3 per cent in the past month – the market might be at record levels, but its performance is very narrowly based. Indeed, only four stocks – Nvidia, Apple, Micron and AMD – account for roughly half the S&P 500’s rise this year.
🔮 Inflation rates are too high, growth rates are weak and there’s not the political will or ability to address the threat of a self-fuelling cycle of escalating debts and interest costs.

Narrative

With the bonds of neoclouds trading below their face value, and their shares imploding, that willingness is going to be tested, along with the sturdiness of the entire ASI sector’s foundations. Rising interest costs are changing the economics of AI, increasing the costs today, deferring to moment of hoped-for profitability further into the future and, by devaluing the net present value of the hoped-for future cash flows, lowering the value and appeal of their equity today. If the supply of that capital, however expensive, were to be throttled, however, it would be extremely destructive – fatal for many – for all companies with exposures to AI, with the probable exception of the stronger hyperscalers, which have their own legacy cash flows to fall back on.

Claims (32 extracted, 3 hedged)

The maths of the boom in artificial intelligence is starting to undermine its foundations, with the implosion in the share price of a leading neocloud last week, and soaring bond yields, highlighting the most vulnerable point in a fragile financial edifice. asserted
maths → start → edifice
Last week the share price of neocloud CoreWeave plummeted 15 per cent and the yield on its bonds – bonds it issued with a yield of 9.675 per cent in June – rocketed to 15 per cent, with the bonds trading at less than 80 per cent of their face value. asserted
bonds → plummet → value
The share prices and bonds of other neoclouds – companies that are built specifically to provide computing power to train AI models – were also ravaged. asserted
that → build → models
Earlier this month, Firmus, a data centre operator, yanked what would have been Australia’s second-largest initial public offering – after investors balked at the $44 billion valuation and the very pricey capitalisation of revenues and earnings from projects that are still on drawing boards. asserted
that → yank → boards
It probably wasn’t a coincidence that the plunge in the value of CoreWeave’s shares and bonds came in the wake of the Firmus debacle and accelerated as last week’s inflation data showed the US inflation rate is also accelerating, presaging higher US interest rates. asserted
rate → come → rates
They commit to building or leasing data centres and installing the massive computing power necessary for AI, using contracts to rent out that capacity to AI frontier labs and the hyperscalers as the backing for the equity and debt that they raise to fund the projects. asserted
they → commit → projects
In CoreWeave’s case – and this is a common and much questioned feature of the AI sector – it has committed to buying billions of dollars of high-end graphics processing units (GPUs) or chips, from Nvidia. asserted
it → question → Nvidia
In turn, Nvidia helped to buttress CoreWeave’s finances by investing $US2 billion in the company and providing a $US6.3 billion commitment to buy any unsold capacity through to 2032. asserted
Nvidia → help → 2032
In effect, Nvidia has helped fund the purchase of its own chips, a feature often described as “circular” financing and one rife throughout the sector. asserted
Nvidia → help → sector
CoreWeave has a not dissimilar arrangement with OpenAI, which has committed to pay CoreWeave more than $US22 billion for “compute” while taking up a $US350 million equity stake in the company. asserted
which → have → company
Those contracts with major AI players – there’s another with Meta – have enabled CoreWeave to raise the equity and debt – it has more than $US40 billion of debt and leases – to fund its data centres rollout. asserted
it → enable → rollout
Adding to the risk, such is the rate of development of the GPUs that the chips they are installing at increasingly exorbitant cost may be obsolete by the time their centres are operational. uncertain
centres → add → time
Moreover, thanks to a community backlash against data centres (no-one wants to live next to them and they can consume vast amounts of energy and water) and the inflation rate, the centres are taking longer than expected to be built and are more expensive than anticipated. asserted
centres → want → energy
As with AI more broadly, there is a significant mismatch between the timing of the capital expenditures and revenue growth which is widening because of the pace at which the sector is growing. asserted
sector → be → which
That yawning and ever-expanding gap has to be funded by ever-increasing amounts of equity and debt. asserted
gap → yawn → equity
Last month the global technology research and advisory firm, Gartner released an analysis that concluded that AI companies were unlikely to deliver enough revenue to cover the expected capital expenditure on IT infrastructure between now and 2030. asserted
companies → release → 2030
It said AI providers would spend nearly $US1 trillion of infrastructure this year and were forecast to spend another $US6 trillion by 2030. asserted
providers → say → 2030
Its research, however, indicated that enterprise and consumer revenues would be insufficient to support profitable returns on the spending. asserted
revenues → indicate → spending
The operators would need to generate $US8.5 trillion of revenue to cover the capital outlays and funding costs while generating a 12 per cent return on capital (which would be the minimum required, given the riskiness, uncertainty and protracted timelines of AI investments). asserted
which → need → investments
The total revenues Gartner forecasts for AI data centres through to 2032, however, only amount to $US3.6 trillion. asserted
Gartner → forecast → trillion
It said more than 80 per cent of the neocloud operators would cease operating independently by 2030. asserted
cent → say → 2030
They’ve been willing to supply vast amounts of cheap capital to all things AI-related in what have been blind acts of faith. asserted
what → supply → faith
As we know from the experience of the 19th century railways boom, and the dot-com boom of the 1990s, AI could transform the world as we know it and still be a poor – even disastrous – investment today. uncertain
we → know → it
The experience of Firmus and CoreWeave and their peers – and analyses like Gartner’s – suggests, some more questioning and scepticism is starting to surface and risk is starting to be priced in to equities and debt. uncertain
risk → suggest → equities
Even Nvidia’s share price has fallen by more than 10 per cent in the past fortnight. asserted
price → fall → fortnight
CoreWeave’s bond yields scream distress. asserted
yields → scream → distress
Its credit default swaps – it now costs almost US1.2 million to ensure $US10 million of its debt – are pricing in a more than 60 per cent chance that it will default within the next five years. asserted
it → cost → years
The company’s June quarter results highlight the challenge it confronts. asserted
it → highlight → challenge
It generated revenue of $US2.6 billion, had capital expenditures of $US9.4 billion and lost $US626 million. asserted
It → generate → million
Both CoreWeave and Nvidia have defended the group’s financials, with CoreWeave’s chief executive, Mike Intrator, saying the markets are acting “irrationally” and that he had confidence in the CoreWeave business model. asserted
he → defend → model
That confidence, however, revolves around the markets’ willingness to continue to supply the ever-swelling amounts of capital that fills in the widening gap between the company’s cash generation and its spending commitments. asserted
that → revolve → generation
With the bonds of neoclouds trading below their face value, and their shares imploding, that willingness is going to be tested, along with the sturdiness of the entire ASI sector’s foundations. Rising interest costs are changing the economics of AI, increasing the costs today, deferring to moment of hoped-for profitability further into the future and, by devaluing the net present value of the hoped-for future cash flows, lowering the value and appeal of their equity today. If the supply of that capital, however expensive, were to be throttled, however, it would be extremely destructive – fatal for many – for all companies with exposures to AI, with the probable exception of the stronger hyperscalers, which have their own legacy cash flows to fall back on. asserted
which → trade → flows
