The AI Boom Looks Late Cycle, Not at a Confirmed Peak
In summary, the froth is fully lit, and cracks are starting to show in financing, credit, and rates. But the confirmation signals are clean. Chips are still selling out, data centers are still full, and Big Tech is still accelerating its spending.
That’s late-cycle behavior, not a confirmed peak. A late-cycle reading isn’t a sell signal either – some of a boom’s biggest gains historically come late. What it means is that we’re no longer flying blind.
What Moves the Board Next
We’ll update the Peak Watch Checklist every week – and the next two weeks should move it.
Microsoft, Alphabet, and Amazon report third-quarter earnings this week: a direct test of “capex growth slows.” The Fed also meets Oct. 27-28, though hike odds have collapsed to around 8% since the latest CPI report – good news for the “Fed tightens” signal. The Nscale and Lambda IPOs will tell us whether Firmus was a one-off or the start of something system-wide. And this week’s news split the difference: Meta’s plan to raise potentially hundreds of billions through a new share class nudges “record stock issuance” the wrong way, while Nebius (NBIS) closing a $3.5 billion facility at reasonable rates is a point for the bulls.
All of which raises the question sitting behind all 13 signals: will this spending ultimately pay off?
Our math says the odds favor yes. But patience is the price of that payoff.
A Long Payback Period Leaves Plenty of Room for Scares
In our base case, revenue doesn’t clear the required-return threshold until 2035, with full payback around 2039. That leaves nearly a decade of room for financing scares, disappointments, and sharp selloffs between here and there.
Which is exactly why this checklist exists. Late-cycle booms reward the investors who stay. Some of history’s biggest gains come in a boom’s final innings; but they go only to the investors who can suss out a shakeout from a top.
The AI trade has clearly moved beyond the clean early innings. Capital is getting more expensive, some investors are pushing back, and credit markets are separating strong borrowers from weak ones.
However, the signals that would confirm a fundamental peak have not arrived together. That’s why we’re watching instead of running.
We’re staying bullish and keeping our eyes on the scoreboard.
We update the full Peak Watch checklist – every signal, rating, and tripwire – each week inside Innovation Investor and Early Stage Investor. The easiest way to start getting it is through my free XPANSE briefing. It lays out the Musk-centered buildout we believe drives this boom’s next leg, the three moves I’d make today, and one lesser-known stock I believe sits at the center of it all. It also shows you how to join us as a member, so the Peak Watch Score lands in your inbox every week before the crowd notices the music changed.
Nobody rings a bell at the top. We built the next best thing.
