The numbers are stated judgments. The record began on 12 October 2026 with starting confidences that a model set in a single reading, from its general knowledge and up to ten developments for each assessment retrieved in the three weeks before (some first reported earlier), and a published rule has made every change since. They are not measured probabilities. The question and the rule are fixed before the record begins, and each change shows its evidence and its reasons. The rule and what is not claimed are on the method page.

Through 2027, access to grid power and interconnection, rather than the supply of accelerators or the availability of capital, sets the pace of AI data centre buildout in the United States.
Status at the end of the week: Holds. The thesis holds when the main assessment stands at 60 per cent or more, the condition it rests on at 50 per cent or more, and no recent change has moved toward the alternative. It is inverted when the main assessment falls below 40 per cent or several recent changes have moved toward the alternative. Otherwise it is strained.

What the update loop read
In this week's 2 daily states, the update loop compared 159 new reports with the causal factors. 151 went to the relevance check, and 16 were linked to a causal factor. 2 linked reports repeated a development already reported and were counted once. It set aside 0 developments that fitted an assessment and each of its rival explanations equally. In the latest daily state, 7 developments were waiting for a second outlet.
12 reports were excluded for scope before anything read them, and only that count is published.
