Quick Summary

Heather Stewart discusses concerns over the potential financial instability within the AI industry. While warnings about AI's existential risks are prevalent, Stewart highlights the economic vulnerabilities of major tech firms like Google and Amazon, which have issued $132 billion in debt this year alone. She points out that rising interest rates and questionable unit economics—where prices for AI services are declining while costs remain high—could trigger a market correction. The article suggests that fears over an impending collapse of the AI bubble may be as immediate a concern as the existential risks posed by unchecked technological advancement.

Story summary

Warnings about uncontrolled AI technology dominating headlines recently raise concerns not just about the potential dangers of AI but also its financial stability. Tech giants like Google, Chinese firms, Meta, Amazon, and Microsoft are investing heavily in AI, with some calling for regulation to ensure safe development. Proposals such as independent analysis of AI models aim to mitigate risks. However, there's a growing worry that the rapid expansion might be unsustainable due to high debts accumulated by these megafirms. A potential collapse of the current AI financial bubble could have significant global economic repercussions beyond just the technology sector.

🔮 More than 2.3m UK households face a sharp rise in mortgage payments as they come off fixed-rate deals in 2027, with the Bank of England expected to begin raising interest rates this week.
🔮 John Healey’s debut budget was far from a blockbuster, but it may come to be remembered for the birth of a plucky new character in the tax and spend universe – little PDEL.
🔮 From Friday, as part of Labour’s Employment Rights Act, unions will have the right to enter workplaces or communicate with staff electronically.
🔮 Hilary Osborne, the Guardian’s money and consumer editor will be joining economics editor Heather Stewart from 3pm (GMT) today to answer your questions on the outlook for our economy.

🔮 Andy Burnham has promised that local leaders in England will no longer have to come “cap in hand to Westminster” ahead of a fresh drive to devolve spending power in next week’s budget.
🔮 Recent dramatic moves in government bond markets have been driven by international factors, but will increase the pressure on John Healey ahead of his first budget as chancellor on 28 October.
🔮 The JRF predicts that, after housing costs, average household incomes will be between £440 and £770 lower in real terms in 2029-30 than when Labour came to power two years ago.
🔮 She said governments could not rely on rapid economic growth to lift the burden of debt – and instead would have to make “very tough political choices”.
🔮 In his speech at Labour’s conference in Liverpool this week, the chancellor warned that the government had limited resources to cushion the worldwide economic shocks hitting Britain, while arguing his budget would have fiscal discipline at its core.

Narrative

Some of the suggestions currently being mooted, including independent analysis of AI models, seem important improvements on the ungoverned status quo. But we should also be alert to the risk that a small number of intricately linked megafirms that have racked up multibillion-dollar debts are hoping the state will throw a regulatory moat around them.

🔮 It will hardly be our most pressing concern if the bots are poised to take over the world, but a collapse of the AI bubble would have repercussions far beyond the US.

Claims (30 extracted, 9 hedged)

Warnings about powerful and uncontrolled AI have dominated the headlines this past week. asserted
Warnings → dominate → headlines
But even amid the omens of apocalypse, it is still worth asking if the entire AI-industrial complex is sailing towards a financial iceberg. asserted
complex → ask → iceberg
It will hardly be our most pressing concern if the bots are poised to take over the world, but a collapse of the AI bubble would have repercussions far beyond the US. asserted
collapse → poise → US
AI bosses have united in recent days to warn us the immensely powerful product they have sunk billions into creating may or may not destroy the human race. uncertain
they → unite → race
Some are also calling for limits on how rapidly the technologies should be allowed to progress, and how they can be used. asserted
they → call → limits
There is ample evidence that AI urgently needs regulating – from the ability of Meta’s pervert glasses (sorry, smart glasses) to film us without consent to the lack of adequate safeguards that allowed swarms of chatbots to go on a hacking spree. asserted
swarms → be → spree
Some of the suggestions currently being mooted, including independent analysis of AI models, seem important improvements on the ungoverned status quo. But we should also be alert to the risk that a small number of intricately linked megafirms that have racked up multibillion-dollar debts are hoping the state will throw a regulatory moat around them. asserted
state → moot → them
Perhaps a government-backed AI “pause” could prevent cheaper Chinese options from encroaching on Silicon Valley’s market dominance, for example. uncertain
pause → back → example
Away from the risk that their product might obliterate human life, there are more old-fashioned reasons for tech bosses to be fearful – including the fundamental one of whether the economics of their businesses work. uncertain
economics → obliterate → businesses
The first worry is the sheer scale of debt issuance being used to fund the hectic pace of the datacentre rollout by the hyperscalers building them – Google, Amazon, Microsoft, Meta and Oracle – $132bn (£99bn) this year alone on one estimate. asserted
worry → use → estimate
In a world of fragile bond markets with yields on 10-year US treasuries, a global benchmark for borrowing costs, hovering at about 5%, the size of these debt piles could be one potential trigger for a market rethink. uncertain
size → hover → rethink
That is especially true given the second reason for concern: the fact that the “unit economics” of AI continue to be questionable and aren’t moving in the right direction. asserted
economics → give → direction
As a recent Bloomberg report put it: “The price of AI is collapsing, while the cost of building it is not.” asserted
cost → put → it
It pointed out that OpenAI has repeatedly cut its fees to hang on to customers, for example. asserted
OpenAI → point → example
An index by the research company Silicon Data that aims to track how much customers are paying for a million tokens – the units of data processed by large language models – shows it more than halving since June, to less than $1. asserted
it → aim → 1
Yet at the same time, frenzied demand for the real-world components of datacentres – semiconductors, for example – is keeping costs elevated. asserted
demand → keep → costs
The maths only works, it seems, on the assumption of epic revenue growth. asserted
it → work → growth
Anthropic apparently told investors recently that its “adjusted operating income” was positive – the only problem being that this measure effectively excludes many of its costs. asserted
measure → tell → costs
As the digital rights campaigner Cory Doctorow puts it: “These companies are claiming that they are so cool that their profitability can only be measured using a novel, secret form of mathematics.” asserted
profitability → put → mathematics
Some aspects of this edifice may seem familiar to veterans of the global financial crisis: masters of the universe, with a business model that is so clever mere mortals can’t be expected to understand it, all propped up with ample dollops of leverage. uncertain
mortals → seem → leverage
A frankly terrifying recent research note from the financial analyst Groundbreaker made this analogy clear, by unearthing a third reason to worry – just totting up debt underrepresents the financial promises underpinning the boom. asserted
totting → make → boom
It sets out the $1.5tn “compute commencement wall” faced by the AI labs over the next couple of years, drawing a comparison with the moment when cut-price “teaser” mortgage rates began to run out in 2007 and 2008. asserted
rates → set → 2007
When those rates ended, flipping low income homeowners on to much higher rates, borrowers began defaulting in their droves, lighting the touchpaper on what became the global financial crisis. According to Groundbreaker’s analysis, in many cases datacentres are being built and kitted out on “take or pay” contracts, with not a dollar due until a deadline is hit (often two to three years), and they hum into life. In the interim, the hyperscaler building the datacentre books the value of the contract as expected future revenue, and shareholders cheer. uncertain
shareholders → end → revenue
Meanwhile, the buyer, (a frontier lab such as OpenAI or Anthropic) doesn’t yet have to account for the costs it will have to pay, once it starts using it. asserted
it → have → it
The analysis suggests the abrupt jump in costs, as contracts mature and datacentres come online, could be an eye-watering $700bn next year and more than $800bn in 2027. uncertain
datacentres → suggest → 2027
That could all be just fine if revenue continues to rocket. uncertain
revenue → continue → ?
Or perhaps not so much, if AI’s end users aren’t prepared to pay enough to cover the costs – perhaps because cheaper options arise. asserted
options → pay → costs
This isn’t, technically, debt – but the impact, if obligations can’t be met in full, would shake the foundations of the entire edifice. asserted
obligations → meet → edifice
Given the spate of recent revelations about revolting bots, the focus on AI safety and the risks to humanity may well be justified, and should be tackled. uncertain
focus → give → humanity
But that should not prevent us from fretting about the delicate, interlinked financial structures that underpin the AI boom, and the risks for us all if they crumble. asserted
they → prevent → us
