Who is delivering?
Ranked by the furthest delivery stage T2C can verify — not by announced capacity or share price. Ties are broken by the earlier evidenced date, then by ticker.

Every megawatt now billing depended on materials, wafers, chips and optics that were certainly made — you cannot bill for compute that was never built. T2C maps the whole chain, 43 node types across 10 stages, and holds sourced supplier records at the delivery end: the optics, the operators, the sites and the billing. Upstream is mapped and described without a supplier record, and says so rather than claiming one. How the chain is tracked
Copper, substrates, rare earths and steel are mined and refined into the components everything downstream is built from.
Miners and refiners sell to component makers.
A foundry grows silicon ingots, slices them into wafers and prints circuits onto them, before they are cut into individual dies.
Foundries sell fabrication capacity to chip designers.
Dies are packaged with high-bandwidth memory stacked beside them, then assembled into accelerator boards. This is usually the headline bottleneck.
Chip designers and memory makers sell accelerators to server builders.
Lasers and optical transceivers move data between racks fast enough that thousands of accelerators behave as one machine.
Optics makers sell transceivers to network and server builders.
An operator secures power, builds the halls, energises them and installs the equipment. This takes years and is where most announced capacity stalls.
Operators sell capacity to the companies training and running models.
The customer tests the delivered capacity and formally accepts it under the contract. Acceptance is the milestone that normally starts the revenue clock.
The customer signs off; the operator has delivered.
Billing begins once the contract's conditions are met and the operator discloses it. Acceptance and billing are different stages and T2C never assumes one proves the other.
The operator is finally paid for the megawatts.

Different evidence stages or measurement bases. These figures are shown side by side and are not subtracted.
Delivery is the thing a contract cannot guarantee. T2C tracks each operator from announcement to billing and shows which gate the evidence actually supports, so a signed agreement is never mistaken for revenue.
The constraint on AI is no longer only chips. It is power, land, grid connections and the years it takes to turn any of them into a hall a customer will accept.
A data centre is an electrical project before it is a computing one. Securing power, connecting to a grid and energising a site are separate gates that can each take years, and T2C tracks them separately for that reason.
Choosing a lens changes the explanation only. It never changes, filters or recalculates a research figure.
