AI bubble early-warning scorecard
Updated 11 Nov 2026. Readings are re-checked against their sources each Monday.
4 of 30 indicators have tripped and 14 are approaching their tripwire. Financing is under strain while end-demand still reads healthy, which points to a funding scare and not yet a demand failure.
What changed this week
No indicator changed status. 0 of 30 readings were updated.

How statuses and the headline are worked out
An indicator is Tripped when its reading has crossed its tripwire, Approaching when it is moving toward it or has met part of a two-part condition, and Clear otherwise. These are judgments recorded with each reading.
A pillar is Tripped when at least half its indicators have tripped. It is Approaching when any indicator has tripped or at least half are approaching. Otherwise it is Clear.
A deflation is called only when End-demand and at least one of Internal funding or Credit are Tripped together. Financing stress alone has produced false alarms, so it is reported as a funding scare.
Default-swap spreads have no free live feed, so those readings come from news reports. This page is a monitoring aid and not investment advice.
