It's no longer just skeptical analysts and short-sellers calling the AI capex boom a bubble -- the Bank for International Settlements, effectively the central bank for the world's central banks, published a report this week comparing the current AI investment surge to historical financial manias including the dot-com bubble, warning that a collapse could damage the broader global economy, according to The Register's July 6 coverage.
The numbers underpinning the warning are real and large. Amazon, Microsoft, Google and Meta have committed a combined total exceeding $700 billion in AI infrastructure capex this year alone -- Amazon at over $200 billion, Microsoft at $190 billion, Google at $180 billion and Meta at $140 billion. The BIS's core critique isn't that AI lacks real value, it's that, in the report's own framing, 'all these things shared a common trait, which is that they attracted a lot more capital than the resulting industry could actually produce' -- a description that applies as easily to AI infrastructure today as it did to fiber-optic cable in 1999.
“Oracle is the sharpest live example of the risk materializing.”
Oracle is the sharpest live example of the risk materializing. The company's stock has fallen more than 40% over the past month following its Q4 earnings, driven substantially by investor doubts about whether OpenAI can actually make good on its committed $300 billion share of the broader $500 billion Stargate compute project -- a lease-payment obligation that assumes OpenAI's revenue growth continues at a pace it hasn't yet proven durable at that scale. As one analyst bluntly put it, 'OpenAI, in case anybody's forgotten, can't pay its own bills' without continuing to raise fresh capital.
The demand-side risk compounds the capital risk: enterprises reportedly don't need a frontier-grade model for more than about 25% of their actual queries, meaning a meaningful share of AI infrastructure spend is being built for peak-capability workloads that represent a minority of real usage -- with cheaper open-source and mid-tier models increasingly able to serve the rest.
For VCs and LPs, this is the most credible version of the AI-bubble warning to date precisely because it's coming from an institution with no short position and no content-marketing incentive -- the BIS's job is financial stability, not clicks. What to watch: whether Oracle's stock stabilizes or continues sliding as more detail emerges on Stargate's actual payment schedule, and whether other hyperscalers face similar scrutiny on their own AI capex commitments in upcoming earnings calls.
