There is so much that is unprecedented about the current AI capital expenditure wave that I'm going to break from my usual format and collate it, with some (mostly amazed) analysis. Consider this an update to my two recent pieces on this topic, here and here.
By way of preamble, the overarching point is that AI spending is eating everything, like a golden retriever left unsupervised in a room full of food bowls. You can shout LEAVE IT! all you want, and the food will still be gone before you can get the door open.
Why did the WSJ think the report so strange? Because imports collapsed (tariffs), exports picked up (tariffs), some capital spending went nowhere (rates smashed real estate), and other capital spending jumped (IT). It was a mess of conflicting forces that somehow worked out, like a tornado passing over a junk yard and whirling out a reasonable facsimile of the Kohinoor diamond. How did that happen?
I'm going to focus on one weird detail of the report, but ignore tariffs, which had a huge impact, but about which I wrote at length earlier this week. The key data point is IT spending, as the following table shows.

The topic of capital expenditure on AI infrastructure has emerged over the past month largely as a warning signal. In an earlier article, Paul Kedrosky notes that current AI datacenter spending is already larger than peak telecom spending (as a percentage of GDP) during the dot-com era, essentially acting as a massive private sector stimulus program, masking weaker sectors of the US economy (flat consumption, weak job growth, declining housebuilding). Other sources have pointed out that AI capex (information processing equipment plus software) has added more to GDP growth than consumers’ spending over the first two quarters of 2025. And Nvidia, arguably the largest beneficiary of this massive spending, now has the biggest weight in the S&P 500 of any individual stock since 1981 and the highest P/E as the index’s top stock since Microsoft in 1999.
