headline: Is this the beginning of the end of the AI stock market boom?
dek: The world is holding its breath as it waits to find out whether this year’s estimated $US1tn investment in artificial intelligence is resting on a castle made of sand. Last week, the Nasdaq 100 – an index of the 100 biggest non-financial stocks on the American tech-heavy Nasdaq exchange – dropped by 5.5%, triggering the usual angst that the AI boom is about to go bust. The recent rot may have started with the failure of Firmus, an Australian datacentre company, to list on the ASX. The multi-billion dollar initia…

problem_reading: Debt-funded, circular AI infrastructure spending by US hyperscalers has made AI bond issuance a large part of credit markets, and the IMF ranks an AI investment bubble bursting as the top risk to the global economy.
problem_evidence: the IMF last week put the bursting of the AI investment bubble at the top of a trio of risks that could threaten the global economy | Corporate bonds issued by these companies now account for nearly 10% of the global investment-grade credit market, from 0.5% at the end of 2024
quick_read: The Nasdaq 100 fell 5.5% in a week, prompting fears that the AI boom is ending. The slide may have been triggered by the failure of Australian datacentre company Firmus to list on the ASX. Tech stocks rebounded on Wall Street on Monday night, and analysts disagreed on whether the drop is a bust or a reset.

The episode matters because AI spending is increasingly financed by debt and by circular deals between companies, which ties credit markets to AI demand. Whether returns justify current valuations is unresolved, with upcoming US quarterly earnings expected to offer the next test and no analyst willing to call a precise market top.
limitation: The source says analysts cannot time the market and that the recent drop may be a reset rather than a bust, so the outcome of the boom is still unresolved.
tag: Evidence-backed problem
key_points: The Nasdaq 100 fell 5.5% last week but is still worth nearly three times its level at the start of 2023. | The Magnificent Seven now make up 35% of the S&P 500, up from 12% a decade ago. | US hyperscalers spent $US425bn on AI capex in 2025 and are on track for $US800bn this year and over $US1.1tn next, according to Minack. | Analysts cited an open source model, possibly from China, and popular opposition to datacentres as potentially more meaningful threats. | CBA economists estimate $150bn of Australian datacentre investment by 2030.
rundown: Firmus, an Australian datacentre company, failed to list on the ASX after an IPO that at one stage was on track to value it above Telstra before it had delivered promised earnings. The article presents this as a possible start of the recent sell-off and a prompt for investors to reconsider similar businesses.

Views differ among the quoted experts. JP Morgan Asset Management's Raisah Rasid calls it a valuation reset rather than doubt about AI and says it differs from the dotcom bubble. Gerard Minack expects AI returns to disappoint but will not call the top, and NAB's Sally Auld notes that big new technologies tend to be overbuilt.

The article describes growing financialisation of AI through borrowing and circular financing, where a manufacturer helps pay for a datacentre in return for chip purchases. Auld said such deals are only as strong as their weakest link, and that an AI bust would matter far more for the US than for Australia.
