AI Procurement Authority Has Moved Out of KM — But KM Still Decides What AI Gets to See

The Legal Stack's Procurement Decision-Maker Shift Report 2026 (published August 10) documents a structural change directly relevant to KM operating models: procurement authority for legal AI tools has migrated from practice group partners and innovation leads to CIOs, CISOs, AI governance committees, and central procurement. At AmLaw 100–200 firms, tools priced above $50,000 annually require an average of 4.2 stakeholder approvals. Security review stalled or failed in 41% of legal AI pilots that did not convert to paid contracts. For KM directors, the strategic implication is a splitting of roles: KM is no longer the primary entry point for legal AI decisions, but remains the function that determines what governed knowledge the adopted tools can access. KM's leverage in the procurement process now comes through its authority over knowledge assets — precedent libraries, matter context, playbooks, and DMS permissions — rather than through deal initiation.
