## Microsoft

**Type:** large diversified tech firm — the **positive example** of a diversified firm engineering credible commitment.

Microsoft is cited as a prime case of a diversified firm *successfully* solving the [[concept-commitment-paradox]] via [[concept-structural-separation-commitment]]. By backing [[entity-openai-d1]] as a legally separate entity, Microsoft ensured its AI engineers and IP could not be easily redeployed to other Microsoft businesses — signaling absolute determination in the winner-take-all AI race and neutralizing the redeployment tell ([[concept-resource-redeployability]]). This is the worked example behind action [[action-structural-separation]].

**Enrichment:** OpenAI has its own board, governance, and capped-profit structure; Microsoft is a major investor/partner but does not fully own it — a real legal and governance separation consistent with the commitment-device framing.
