Hyperscaler capex flags the compression — three of four guide down on Q2.
The AI margin compression thesis stops being a forecast and becomes the line item. The grid is the new GPU constraint.

Three of the four hyperscalers cut Q2 operating-margin guidance on the same week. Each cited GPU lead times widening past nine months and power-siting delays in three of the most active inference geographies. The fourth held guidance but flagged "elevated build risk." That is now the band.
The AI margin compression thesis Palanor has carried since 2025 is no longer a forecast about what could happen. It is the data point you see in the guidance language. Read the Capital Tightness reading alongside the AI Margin Compression Index — the second is the funding side of the first.
The Council's read: the compression has a second binding variable now beyond chips. The grid is the constraint that won't yield to a fab-build the way GPU supply eventually will.
