Claim LD11-HQ-C01 (v1.0)

Concentration claims in AI must identify the stack layer, market definition, metric, geography and period; concentration at one layer does not establish concentration or power at another.

Provenance and status

Claim type: Interpretation
Publication status: Eligible for publication
Verification state: SocioLens synthesis across the debate’s sources; there is no single primary source to check it against. Who checked this claim is not recorded for it; claim checks so far were AI-led, and no person has checked claims against their sources.
Does not license: A single “AI market share”, whole-stack oligopoly claim, or power inference from concentration alone
Limitations: Exact market definitions remain source-specific
Source (as cited): R06 HQ cross-batch synthesis
Source type: Several types of source (recorded as “Multiple source types”)
Institutional position: Mixed
Maturity of the evidence: Mature evidence
Recorded date: 25 September 2026
Currentness / correction: This is the current version. No correction or concern is recorded on its sources.
