18,980 supply-chain records from licensed corporate databases and CSET ETO. Relationships identify suppliers and customers, with product or service descriptions where available. The cascade model uses the recorded criticality and supply share; missing values default to 5 out of 10 and 30%, respectively. Sole-source relationships have a minimum criticality of 9. These assumptions affect the simulated disruption.
36 programs, with separate amounts for announced funding, commitments and disbursements. Country records identify the disclosures behind these amounts and distinguish government funding from private investment included in a headline pledge. Facility and chip-allocation records provide evidence of implementation where available.
3,435 BIS Entity List designations, linked to their published sources. Company matching combines names with recorded ownership relationships. An ownership connection can identify a company for further review; the applicable restrictions depend on the rule and its effective date.
GPU rental prices divided by dense BF16 throughput, expressed in dollars per petaFLOP-day. Daily refreshes cover AWS, Azure and Oracle pricing; GCP, CoreWeave and Lambda prices are checked manually against published price pages. Each observation carries its retrieval date. Hardware throughput comes from Epoch AI's ML Hardware database; prices on this basis exclude the extra throughput available from structured sparsity.
Simulates disruption through supplier and customer relationships, with adjustable severity and propagation assumptions. Downstream effects depend on supply share and criticality; upstream effects use a customer's share of the supplier's weighted relationships. In historical checks, the ASML blanket-halt scenario did not reproduce the selective 2020 restrictions, and the CoWoS comparison used parameters calibrated after the event. A comparison labelled ‘Russia helium 2022’ used a Qatar–Hormuz helium scenario unrelated to the 2022 disruption of Ukraine’s neon supply.
Compares model training budgets and estimated facility throughput with published compute thresholds. Facility calculations use recorded hardware where available and convert power capacity to throughput otherwise. Training duration and utilization are assumptions; the threshold descriptions state the associated legal conditions and whether the instrument remains in force.
Attributes data-center capacity to its host country and to the jurisdiction identified through corporate ownership. A separate ownership-transparency assessment classifies facilities by the available sources for their corporate ownership. The two assessments use their own stated facility populations and capacity totals.
Examines facilities whose host country and corporate ownership connect different export-control jurisdictions. Ownership chains are assessed against a versioned classification of national regimes. A documented connection to a jurisdiction outside the coordinated group remains visible when a later part of the ownership chain is unknown.
Documents the formulas and source definitions behind the analysis, including default values and uncertainty. The capacity and cascade calculators allow researchers to change assumptions and inspect the resulting estimates.
