Score breakdown

A · Speed17 / 25Revenue re-accelerated to +17.8% at $331.8B scale; Azure +41% with Q4 at +43% — real speed, capped by sheer size
B · Moat47 / 60Installed base + workload gravity + distribution (Windows · M365 · GitHub · LinkedIn): a composite lock-in, the deepest in the index after Alphabet
C · Creative destruction10 / 15Copilot paid seats passed 30M and work is being delegated to AI — the behavior change is real but early against a base of hundreds of millions
D · BlitzFailing−3Light demerits (−3): antitrust scrutiny and the OpenAI structure. The watch item is capex discipline, not governance

Radar axes (0–100): Moat 78.3 · Speed 68 · Creative 66.7.
