Digital Backbone covers the full connectivity stack — data centers, power grids, terrestrial fiber, and the low Earth orbit networks being built above it all.

Six themes. One thesis.
Every piece of analysis fits one of six themes — from orbital networks above to the power grid below. Together they map the full physical layer.
Orbital Infrastructure
SpaceX and Amazon build their own satellites. A dozen sovereign constellations can't. Who builds the hardware for everyone else — and what is that worth?
The Power Problem
The AI buildout needs 80+ GW of new capacity. Energizing a site takes 3–5 years. The grid can't keep up — and that gap is the entire thesis.
AI Infrastructure Demand
The market tracks chips. We track what's underneath — the land, the power interconnects, the fiber, and the capital structures behind every new data center.
Deal Flow & Valuation
Fiber keeps getting bought out of public markets at premiums. Miners are converting to AI compute at a fraction of greenfield cost. We track the deals that reveal mispricing.
Sector Scorecards
Company-level deep dives on SpaceX, MDA Space, Rocket Lab, CoreWeave, Uniti, and the operators building the physical layer. KPIs, competitive dynamics, and bear cases.
Picks-and-Shovels Blind Spot
Operators grab headlines. We find who builds the infrastructure behind them — the satellite manufacturers, the retrofit specialists, the spectrum holders nobody's underwriting.
