When this applies
when deciding capital investment in scarce, long-lead-time capacity for a product whose demand correlates tightly with that capacity
The takeaway
When a resource's usage tightly correlates with available capacity, use that ratio to size forward investment, planning years ahead of the lead time required to build the resource.
Why it works
If observed usage/revenue tracks capacity 1:1 historically, the capacity figure becomes a leading indicator you can extrapolate forward, even though building that capacity requires multi-year lead time.
One level up
In supply-constrained markets, underinvestment is the larger strategic risk; use historical ratio evidence to justify aggressive forward capacity commitments.
Where it stops holding
This stops working when the correlation between capacity and revenue breaks down (e.g., demand saturates, substitutes emerge, or price elasticity hasn't been tested and turns out to be low).
Detail
procedure:- Track historical compute capacity against in-period revenue to find the ratio
- Confirm the ratio is accelerating/consistent across multiple years
- Use the ratio to size compute orders years ahead of actual need, since data center lead time is multi-year
- Cross-check against external signals: industry-wide hardware/chip spending growth
benchmarks: {"2023":"200MW compute, $2B ARR","2024":"600MW compute, $6B ARR","2025":"2GW compute, $20B+ ARR","industry hardware spend increase":"$220B","chip forecast increase":"$334B"}
rationale: Because compute lead times span multiple years, decisions must be made today for demand 3+ years out; using the historical compute-to-revenue ratio reduces guesswork.
In their words
We exited at 23 at 2 billion in ARR, so 200 megawatts, 2 billion. We exited at 24 at 6 billion, so 6 billion, 600 megawatts. And we exited last year a little over 20 billion, 20 billion, 2 gigawatts.
