AI’s ‘picks and shovels’ stocks have lost $4.2tn, the FT reports

Shares in data centre construction companies have lost $4.2tn in value as the boom in the AI trade unravels, the Financial Times reported today. In its public summary, the paper says the so-called “picks and shovels” companies were hit hard by the tech sell-off.

What the FT has made public so far

The FT article is behind a paywall, so only its headline and standfirst can be read. They give the loss figure and name the group affected: the companies that supply the AI build-out, rather than the developers of the AI models themselves. The public text does not say over what period the losses were measured, which companies are counted, or how much each lost. Aiholics has not independently verified the figure, and the company-level details in the full article are not covered here.

Why suppliers feel the sell-off first

“Picks and shovels” is the label investors use for businesses that earn money from the AI build-out whether or not any single AI product succeeds: builders of data centres, makers of chips and providers of power and cooling. That position was seen as safer than backing the model developers. The FT headline suggests the sell-off has now reached them too.

Earlier Reuters coverage of the wider market rout, carried by Devdiscourse, listed several pressures on infrastructure stocks. Reuters cited investor fears that the Democrats’ midterm victory could slow data centre expansion, along with local opposition over power and water use, higher interest rates and doubts about returns on AI spending. Those are Reuters’ reported explanations, not findings of the FT piece.

Borrowed money raises the stakes for builders

Much of the build-out is financed with debt, which is why a fall in share prices matters beyond paper losses. Aiholics reported earlier this week that CoreWeave was turning to chip-backed debt and customer pre-payments to fund its expansion. Our explainer on GPU-backed debt describes how AI chips and customer contracts became loan collateral. That kind of financing depends on lenders and investors staying willing to fund new capacity, so weaker equity markets can make it harder to arrange.

The sell-off also sits close to the AI labs. Aiholics covered Anthropic’s IPO price range, with chipmakers among the buyers. Reuters noted that some analysts wondered whether the sell-off could delay that listing. None of the sources read for this report says that any listing plan has changed.

What the headline number does not settle

A paper loss of this size says how far prices have fallen, not whether data centre projects are being cancelled or delayed. The FT’s public text does not claim either. It is also unclear how much of the loss is a lasting repricing and how much could reverse if the market recovers. The full FT analysis may address this, but its details are not public. Aiholics will update this report if the paper’s figures or any company responses become available.
