Which framing best protects shareholder value?

Option 72-h cap delta Confidence Dominant risk
Status quo −$10B to +$10B LOW Read as no AI strategy; slow bleed
Aggressive −$100B to −$150B MED Triggers “CapEx arms race”; tail goes deeper
Backlog-anchored −$20B to $0B HIGH Anchors spend to revenue visibility
Staged −$15B to $0B MED Read as lack of conviction

Pre-event verdict / post-event truth

When the world picked the rejected option.

Glasshouse said, 3 Feb 2025

Pick Backlog-anchored. Avoid Aggressive.

Aggressive framing forecast at −$100B to −$150B in 72 h, MED confidence, with “CapEx arms race” as the dominant destructive narrative.

The world did, 4–7 Feb 2025

~$215B erased in 90 minutes.

Alphabet shipped the Aggressive equivalent. Stock fell ~9 % after-hours; ~$165B gone by the next session close; conservative $150–$200B in the 72-h window.
