Most recent verified filing: Q2 2026 Form 13F. EDGAR · filed as STATE OF WISCONSIN INVESTMENT BOARD
This is not assets under management. Form 13F covers US-listed equities and certain related instruments only — it excludes fixed income, real estate, direct stakes, private holdings and all non-US listings, and for most institutions it captures a minority of total assets. It is shown because it arrives quarterly, roughly 45 days after each quarter end, while the AUM figure above is annual. It tells you the record is live; it does not restate the ranking.
