The AI Margin Compression Index v2 reads four manual-entry signals — Microsoft, Alphabet, Meta, and Amazon AWS AI capex. Each quarter, after the four file their 10-Qs, an admin enters the new values in Palanor and the Index recomputes against the fresh data.
Where to enter the values
The entry page lives at /amc-capex and is gated to Palanor employees. It is also linked from the admin side rail under Clients.
The page shows the current Index reading at the top, then a card per signal with the most recent quarterly value and an input box for the new one. Below each input you can expand a History dropdown showing the last twelve quarters of recorded values for that signal.
The quarter selector
At the top of the form is a date picker. Palanor defaults it to the next quarter-end after your latest recorded observation — typically the quarter that just finished. Adjust the date if you are backfilling an older quarter or correcting a previous entry. Observations are upserted on the (signal, observed_at) key, so entering a value for an existing quarter overwrites the prior value cleanly.
What to type
For each hyperscaler, find the AI infrastructure capex figure from their most recent 10-Q. Type the number in billions of US dollars — so if Microsoft reports $27 billion in AI capex for the quarter, type 27. Decimals are fine (27.5).
You can leave any signal blank. The form only writes values you actually entered. If only Microsoft and Alphabet have filed and Meta and Amazon are still pending, enter those two now and come back when the other two file.
What happens on save
Save writes one row per entered value into signal_observations, then triggers a recompute of the AMC Index. The new reading appears in a confirmation banner at the bottom of the form. The Index page on the public catalog reflects the new value as soon as Vercel deploys the next request.
A note on data integrity
Manual entry means the Index is exactly as honest as the admin doing the entering. The expectation is that the value comes from the official 10-Q — not an analyst report, not a press release headline that may differ slightly. Keep the source filing open in a tab while you type, and the values stay defensible.
Future versions of this Index (v3, planned) will automate the ingestion via SEC EDGAR filing parsers. Until then, this manual surface is the system of record.
