A Trading Habits Report
The AI Infrastructure Buildout Is Genuine. In An Original Simulation, Reacting To Every Headline Inside It Beat Simply Holding Just 37.4% Of The Time.
Microsoft, Alphabet, Amazon, and Meta have raised their own capital-spending guidance quarter after quarter through 2024 and 2025.
Multiple financial outlets reported their combined guided capex for 2025 above $300 billion.
That is a documented, reported pattern, not a rumor.
But the buildout is really four separate markets stacked on top of each other: compute demand, GPU supply, data-center construction, and the electric grid underneath all of it.
Each one has its own bottleneck.
Each one moves on its own catalysts.
And this report walks through exactly how they fit together, and what happens to an account that reacts to every headline inside the theme instead of just holding through it.
Read this report and you'll get the actual reported hyperscaler capex pattern and why guidance keeps moving one direction.
You'll get the documented power-grid constraint behind the buildout, including one dated case study of a power deal built specifically to solve it.
You'll get the exact point in the GPU supply chain reporting has identified as the actual bottleneck, and it isn't chip design.
And you'll get an original simulation, 8,000 runs, pricing out what chasing every theme-moving headline costs against simply holding a position.
Holding beat headline-chasing in roughly 63 percent of the 8,000 simulated runs.
The chasing account's median result finished more than $3,000 behind holding, on a simulated $10,000 start.
A genuine, well-documented buildout, and a costly way to trade it anyway, once the lag between a headline and a reaction gets priced in.

Behind The Report
Capex Guidance Kept Moving One Direction. Then We Simulated What Chasing It Costs.
The Pattern That Started It
Through 2024 and 2025, Microsoft, Alphabet, Amazon, and Meta each raised their own capital-spending guidance on successive quarterly earnings calls. Multiple financial outlets reported their combined guided capex for 2025 above $300 billion, a figure that moved up, not down, each time it was updated.
That pattern is genuine and well documented. It says nothing, on its own, about whether reacting to every headline inside the theme actually outperforms simply holding a position through it, which is exactly what this report tests directly.
What The Simulation Found
This report built an original simulation on top of that question: 8,000 runs, 10 simulated years each, comparing an account that holds a position through every theme-moving headline against one that reacts to each headline after a stated lag.
Holding's median result landed near $13,599 from a $10,000 start. The headline-chasing account's median result landed near $10,400, and it only beat holding in about 37.4 percent of the runs. Full method and assumptions are inside the report.
Holding Through Headlines vs. Reacting To Every One
A simplified rendering of the simulation discussed on pages 13 and 14 of the report. Background only. The report itself covers the full method and every stated assumption.
Try It: A Headline-Chasing Cost Calculator
A simplified version of the cost math behind the report's own Section 7 simulation, using the report's stated 9.3 percent illustrative annual drift and a fixed illustrative lag-cost figure per reaction. Not a forecast, not tied to any actual security, and not a recommendation. The full 8,000-run simulation, with its complete assumptions, is in the report.
Background only. Nothing on this page or in this report is a recommendation to buy, sell, or hold any security or instrument, or to trade around the AI infrastructure theme.
Common Questions
Is the AI infrastructure buildout backed by anything besides headlines?
Yes. The clearest evidence is each hyperscaler's own reported capital-spending guidance, which multiple financial outlets reported crossing $300 billion combined for 2025 across Microsoft, Alphabet, Amazon, and Meta, moving higher on successive quarterly calls rather than being set once. That documents the spending. It does not, by itself, tell you how to trade around it, which is what the rest of the report covers.
Does this report tell me which stocks to buy?
No, and it isn't trying to. Companies named in it, including Microsoft, Alphabet, Amazon, Meta, Nvidia, TSMC, and Constellation Energy, appear only because they are documented, publicly reported participants in the specific events, deals, or figures described. No stock list, no screen, and no price target appears anywhere in it.
What did the headline-chasing simulation actually find?
Eight thousand simulated 10-year runs, comparing an account that holds a position through every theme-moving headline against one that reacts to each headline after a stated lag, exiting on negative news and re-entering on positive news, with a stated switching cost applied each time. Holding's median result landed near $13,599 from a $10,000 start. The reactive account's median result landed near $10,400, and it only beat holding in about 37.4 percent of the runs. The full method and every assumption are on pages 13 and 14.
What's the actual bottleneck in the GPU supply chain?
Reporting through 2023 through 2025 pointed specifically at advanced-packaging capacity, the step that combines a finished chip with its memory, not chip design or raw wafer fabrication. Page 9 covers all three steps in the chain and why that distinction matters for reading GPU-supply headlines correctly.
