From Supply Chain to Chokepoint
A supply chain becomes a chokepoint when one link is both scarce and hard to widen, and every buyer must pass through it. The modular integrator tier is becoming that link. Component supply below it is fragmenting outward; construction above it is a commodity; but the assembly-and-test layer in the middle is consolidating, because scale, component allocation, and a production learning curve all reward the largest player and punish the small one. The flywheel is self-reinforcing: more volume buys more allocation and lower cost, which wins more volume. Buyers who fail to see the pipe narrowing will find, one order too late, that the delivery date is no longer theirs to set.

What conditions turn the modular integrator tier from an ordinary supplier into a strategic chokepoint?
Show the answer
Three conditions in combination. First, scarcity that is slow to relieve: new factories, skilled crews, and long-lead components such as large transformers and switchgear cannot be expanded quickly, so output lags demand. Second, a self-reinforcing scale advantage: larger integrators secure more component allocation and ride a production learning curve to lower cost and higher reliability, winning still more volume. Third, unavoidability: every buyer needing fast, de-risked power and cooling must pass through this single assembly-and-test layer. When one slow-to-widen link is unavoidable, it sets the schedule and the price.
