TIAA was created in 1918 with funding from Andrew Carnegie to give college teachers a pension, and still serves about five million people at academic, medical, cultural and research institutions.

CalPERS (California Public Employees' Retirement System)

CalPERS manages approximately $500 billion in assets as the largest US public pension fund, yet it holds just 38% of the assets of the top-ranked TIAA.

The Teacher Retirement System of Texas was established in 1937 and manages retirement and health benefits for around 1.9 million current and former Texas educators, making it one of the largest public pension funds in the United States.

Washington State Investment Board (WSIB)

State of Wisconsin Investment Board (SWIB)

SWIB manages the Wisconsin Retirement System, one of the very few US public pension plans that is essentially fully funded. The reason is structural rather than lucky: WRS shares investment risk with its retirees, so annuity payments can be adjusted downward as well as upward with investment results, which stops the liability outrunning the assets.

Florida State Board of Administration (SBA)

Florida SBA's $220 billion asset base makes it one of the largest U.S. public pension funds. It serves over 1 million members across state, county, and municipal workers, and delivered a 7.9% net return in fiscal 2023. In 2023 Florida enacted a law barring ESG considerations from state investment decisions, reflecting political tensions around pension mandates.

Ohio State Teachers Retirement System (STRS)

Ohio STRS manages roughly $96 billion for about 500,000 active and retired public school educators and was founded in 1920. In an unusual governance fight, reform candidates backed by retired teachers won seats on the board and staff bonus payments became a public controversy that drew in the Ohio Attorney General.
