AI Holders Summary · Q2 2026

COST registers 4,060 institutional filers with roughly $293B in aggregate 13F value. The register is structurally passive-led and notably thin on active discretionary conviction: BlackRock, Vanguard Capital Management, State Street, and FMR dominate the top tier, while active names like Capital Research and Invesco carry far smaller stakes than they do in peer consumer-discretionary or consumer-staples registers. That scarcity of active-manager overlay is itself the defining Costco signal.

The top tier is passive by design. BlackRock leads with roughly $34.8B, Vanguard Capital Management carries roughly $28.7B, and State Street rounds out the top three at roughly $18.1B. FMR/Fidelity appears at roughly $10.7B, followed by Geode Capital Management and Vanguard Portfolio Management. These positions scale with benchmark and ETF-asset growth.

The active-manager layer is thin, and that thinness is informative. Capital Research Global Investors and Invesco Ltd. appear in the active tier at materially smaller stakes than they maintain in Walmart or Target registers. The absence of large active-manager overweights is not a negative signal on Costco business quality; it reflects the reality that Costco membership model produces unusually predictable cash flows that do not reward bottom-up research differentiation.
