The World's Largest Pension Funds (2025)
Last updated: 25 May 2026
The world's largest pension funds are among the most powerful investors on earth, collectively managing tens of trillions of dollars on behalf of hundreds of millions of beneficiaries. This page sets out the largest funds by assets, the methodology and sources behind the figures, and the caveats that anyone citing a pension-fund ranking should keep in mind. For how these institutions actually invest, see the Canadian pension model and total portfolio approach; reporters can request comment via pension fund expert comment.
The headline: Norway overtakes Japan
The defining change in the 2025 ranking is at the very top. According to the Thinking Ahead Institute's World's Largest Pension Funds 2025 study (compiled with Pensions & Investments, using data to the end of 2024), Norway's Government Pension Fund has overtaken Japan's Government Pension Investment Fund (GPIF) as the world's largest pension fund — ending more than two decades of Japanese leadership. The Norwegian fund was reported at roughly US$1.77 trillion, around 7% larger than GPIF. Treat both figures as approximate: they move with markets and currencies and vary by source.
Methodology and sources
The ranking below follows the Thinking Ahead Institute / WTW World's Largest Pension Funds 2025 (the "Top 300"), which measures assets under management to the end of 2024 and is the most widely cited cross-country pension league table. A few rules matter for interpretation: figures are converted to US dollars (so currency moves affect rank); compilers decide what counts as a single "fund" versus a broader system; and the as-of date is end-2024, so more recent market moves are not captured. We report the figures we can source with confidence and treat all others as approximate, directing readers to the primary report for exact numbers.
The largest pension funds
| Rank | Fund | Country | Notes |
|---|---|---|---|
| 1 | Government Pension Fund | Norway | ~US$1.77tn; newly the world's largest (see classification note below) |
| 2 | Government Pension Investment Fund (GPIF) | Japan | ~US$1.66tn; former long-standing leader |
| 3 | National Pension Service | South Korea | Among the largest globally |
| 4 | Federal Retirement Thrift | United States | The federal employees' defined-contribution plan |
| 5 | ABP | Netherlands | Civil-service and education scheme |
| 6 | California Public Employees (CalPERS) | United States | Largest US public pension |
| 7 | Canada Pension Plan (CPP Investments) | Canada | Flagship of the Canadian model |
| 8 | Central Provident Fund | Singapore | National savings scheme |
Ranks 3 through 8 reflect the well-established membership of the global top tier; exact ordering and figures below the top two shift year to year and should be verified against the Thinking Ahead Institute report before publication. Other funds consistently near the top include CalSTRS, the Dutch fund PFZW, Canada's other large plans, and several large Asian national schemes.
The scale of the top tier
The aggregate numbers are as striking as the individual ranks. The Thinking Ahead Institute reported that the top 300 pension funds reached a record of about US$24.4 trillion at the end of 2024, growing 7.8% over the year. The top 20 funds alone managed more than US$10.3 trillion — about 42% of the entire top-300 total — underlining how concentrated long-term pension capital has become. This concentration is part of why the largest funds increasingly behave as universal owners: at this scale, a fund effectively holds a slice of the whole economy.
A classification caveat that matters
Norway's fund illustrates a trap that catches even experienced reporters. The Government Pension Fund Global is funded by petroleum revenue and holds no individual member accounts, so by structure it resembles a sovereign wealth fund — indeed it tops sovereign-fund league tables too, where its manager NBIM is reported at around US$1.76 trillion. Because the capital is earmarked for long-term public and pension obligations, pension-fund compilers include it among pension funds. The same institution can therefore legitimately appear at the top of two different rankings. When citing any figure, name the source and the category it used.
What is driving the growth
Several forces lifted pension assets to records: strong public-equity markets through 2024, continued contributions, and a long-running shift into private markets — private equity, infrastructure, and increasingly private credit — in pursuit of returns and diversification. Notably, the Thinking Ahead Institute also reported that many of the largest funds are now treating artificial intelligence as a strategic priority, both as an investment theme and as a tool in portfolio management. For how these allocation choices are framed, see global asset owners.

Beyond the headline figures
Three further points help anyone using this ranking. First, the gap between defined-benefit and defined-contribution giants matters: some of the largest entries (such as the US Federal Retirement Thrift) are defined-contribution vehicles where members bear investment risk, while others are defined-benefit plans promising set payouts — they are not strictly like-for-like even when their assets are similar. Second, several of the largest "funds" are really systems or reserve funds with national mandates rather than conventional occupational pensions, which is why the same name can move between sovereign-fund and pension-fund tables. Third, geography is concentrating: North America, Japan, South Korea, the Netherlands, and the Nordics dominate the top tier, while fast-growing systems in emerging markets are climbing but not yet at the very top.
Why pension-fund scale matters now
The scale captured in this ranking is not just a curiosity. Because the largest pension funds now hold a meaningful slice of global public and private markets, their allocation decisions move asset classes, set norms for governance and stewardship, and increasingly shape the financing of infrastructure, housing, and the energy transition. When the top funds collectively tilt toward private credit, infrastructure, or AI, they reprice those markets for everyone. That is why pension-fund rankings are read closely not only by the funds themselves but by asset managers, policymakers, and the companies that depend on long-term capital — and why a single year's change at the top, like Norway overtaking Japan, is treated as genuine news rather than trivia.
We maintain this ranking as a living reference and update it as new editions of the underlying studies are published and as major funds report fresh figures. If you are a reporter on deadline, we can talk you through how any specific fund on this list is positioned, how its assets compare with peers on a like-for-like basis, and what its recent allocation moves signal for the wider market — all on a sourced, public-information basis. If you are a researcher, you are welcome to cite the page with a link while verifying the underlying numbers against the primary studies and the funds' own annual reports.
