The stack,
by layer.

The public snapshot keeps each layer’s current signal tied to the same immutable payload. Read the component primitive and source-specific observation count before drawing a market conclusion.

These are index signals, not universal transaction totals or promises about any individual item. Explore the component records.

Four indices.
The whole physical stack.

Each index aggregates the components defined in its record. Collection windows, configured weights, effective weights, primitives, and counts are disclosed per index; no universal window or equal-weight claim is implied.

One email.
Every month.
One public deep dive.

Free, forever. The collection snapshot remains public and citable; the editorial email cadence is separate from the date of any underlying observation.

  • The collection snapshot

    Current values, comparisons when supplied, and immutable snapshot links for all four indices.

  • The public deep dive

    A focused look at a physical-AI bottleneck, geography, component, or market dynamic.

  • Methodology updates

    Changes to composition, source handling, or disclosures are dated and explained.

The physical AI buildout needs a reference language for the infrastructure beneath the headline. SpotWire makes the source and the uncertainty visible.
