CalPERS
California public employees
As of June 30, 2026 · $162–177B 13F sleeve
Largest U.S. public pension. VOO is the flag; NVIDIA, Apple, Microsoft, Amazon sit behind it.
Main Street Funds
Pensions, endowments & sovereigns
Asset owners — the money behind the Titans. Five names per kind to start. Open the rest of the ten. Each book shows five holdings; expand for the full sleeve we track.
These are asset owners — pensions, endowments, sovereigns, and foundations — not hedge-fund Titans. U.S. 13Fs (as of June 30, 2026) show public longs only, ~45 days late. Many books are mostly private markets; those names are labeled mix / notable stakes, not a full ticker tape.
Public pensions
Teachers, firefighters, and state workers. The public 13F is usually an index sleeve plus mega-caps — the real book also holds bonds, private equity, and real assets.
13F
CalSTRS
California teachers
As of June 30, 2026 · Large 13F · index-heavy
Second California giant. Same market-cap spine as CalPERS, run for teachers.

Florida SBA
Florida Retirement System
As of June 30, 2026 · State Board of Administration
Runs the Florida pension. Public equities look like the S&P.
University endowments
Yale, Harvard, Stanford. Most of the money is in private equity, venture, and outside managers. The 13F is a thin public window — if they file at all.
Harvard
Harvard Management Company
As of June 30, 2026 · $4.3B 13F · 19 lines
The public sleeve is concentrated: SpaceX (via the 13F line), TSMC, Cerebras, Amazon, Alphabet. The rest of the endowment is private.
Yale
Yale Investments Office
As of 2026 report · Mix · little public tape
The Swensen model: heavy alternatives. There is no Berkshire-style top-10 stock list.
Stanford
Stanford Management Company
As of June 30, 2026 · Endowment · thin 13F
Large venture and private book. Public names, when filed, look like mega-caps plus a few direct stakes.
Princeton
PRINCO
As of 2026 report · Endowment mix
High alternatives weight. Public equity is mostly through managers.
MIT

Sovereign wealth funds
Country money. Norway publishes almost everything. Singapore’s Temasek files a U.S. 13F. PIF, ADIA, GIC, and CIC mostly show up as mix, press stakes, and 13Ds.
Norway NBIM
Government Pension Fund Global
As of June 30, 2026 · ~$1.0T U.S. 13F · 7,200 companies worldwide
The gold standard. NVIDIA, Apple, Alphabet, Microsoft, TSMC, Amazon, Broadcom. Tiny slice of each — a market, not a bet.
Temasek
Singapore
As of June 30, 2026 · $37B U.S. 13F

ADIA
Abu Dhabi Investment Authority
As of 2026 report · Mix · few tickers
Among the largest SWFs. Almost no public ticker tape.
Corporate / union pensions
