The largest pension funds hold a different mix from family offices and answer to different constraints. Among top-20 pension funds with available data, alternatives formed 23.9% of the simple-average portfolio and 17.3% on an asset-weighted basis, according to the Thinking Ahead Institute and Pensions & Investments Global Top 300 Pension Funds study, September 2026. The two populations stay separate: pension portfolios start from liabilities.
How large and concentrated are the top 300 pension funds?
The top 300 pension funds in the Thinking Ahead Institute and Pensions & Investments study held $27.694 trillion, with reported AUM rising 13.4% in 2025. AUM growth is not investment performance. The top 20 held $11.856 trillion, or 42.8% of ranked assets, and the top 50 approximately 59%. [1]
| Type | Funds | Reported assets | Approximate share |
|---|---|---|---|
| Public sector | 127 | $11.108 trillion | 40% |
| Sovereign pension | 24 | $8.590 trillion | 31% |
| Private independent | 67 | $4.489 trillion | 16% |
| Corporate | 82 | $3.508 trillion | 13% |

Public-sector and sovereign pension funds together represent 151 funds and 71.1% of assets. Sovereign pension funds are established to meet pension liabilities and differ from the wider sovereign-wealth-fund category. [1]
How do the largest pension funds allocate?
Four of the top 20 funds lacked allocation data. The study therefore presents the remaining funds using both simple and asset-weighted averages, and the difference is material. [1]
| Asset class | Simple average | Asset-weighted average |
|---|---|---|
| Equities | 46.2% | 51.2% |
| Bonds | 27.6% | 28.8% |
| Alternatives | 23.9% | 17.3% |
| Cash | 2.2% | 2.7% |

A simple average describes the typical disclosed fund. An asset-weighted average gives more influence to the largest funds. The 23.9% figure is not the share of all pension assets in alternatives.
How does allocation vary by domicile and size?
| Asset class | North America | Europe | Asia-Pacific |
|---|---|---|---|
| Equities | 42.6% | 48.3% | 51.4% |
| Bonds | 17.0% | 36.2% | 36.4% |
| Alternatives | 36.3% | 14.7% | 10.5% |
| Cash | 4.1% | 0.9% | 1.7% |
Source: Thinking Ahead Institute / Pensions & Investments, Global Top 300 Pension Funds, September 2026, p. 41. 183 funds with complete disclosure, covering 74% of ranked assets.
North American funds in the disclosed sample hold a much larger alternatives share. Region identifies where the fund is domiciled, not where its alternatives are invested. The study does not break alternatives into private equity, private credit, real estate, infrastructure or hedge funds. [1]
| Group | Equities | Bonds | Alternatives | Cash | Alternatives, simple |
|---|---|---|---|---|---|
| Top 20 | 51.2% | 28.8% | 17.3% | 2.7% | 23.9% |
| 21 to 50 | 44.1% | 22.6% | 31.7% | 1.6% | 31.0% |
| 51 to 150 | 42.4% | 27.2% | 28.0% | 2.4% | 28.4% |
| 151 to 300 | 39.4% | 32.7% | 25.5% | 2.4% | 25.4% |

The largest funds are not the most alternatives-heavy. Funds ranked 21 to 50 report the highest weighted alternatives share, at 31.7%. [1]
Where are the pension funds based?
North America holds 44.7% of top-300 AUM, Asia-Pacific 26.6%, Europe 24.6%, and Latin America and Africa 4.2%. The United States accounts for 149 of the 300 funds and 38.9% of AUM. Other major domiciles include Japan (9.5%), Norway (7.9%), Canada (5.8%), Australia (5.2%), the Netherlands (5.1%) and South Korea (3.9%). [1]
How do pension funds compare with family offices?
The populations differ, so the figures stay side by side rather than combined. Citi Wealth's 2026/27 Global Family Office Report records 30% public equities, 16% fixed income and 12% cash for its family-office sample, alongside detailed alternative categories such as 4% hedge funds and 2% private credit. [2]
Three differences limit comparison. The surveys use different categories: the pension study reports a single alternatives bucket, while Citi reports separate private-market and hedge-fund lines. The dates differ: pension assets are mainly 2025, while Citi's survey began in June 2026. The weighting methods differ too. No pooled investor average is meaningful. Our article on the family-office portfolio covers Citi's data in full.
Why do liabilities change the picture?
Among 277 funds disclosing plan type, representing 94% of ranked AUM, defined-benefit plans account for 57.8% of disclosed AUM, defined-contribution 28.5%, reserve funds 12.8% and hybrid plans 0.9%. Defined-contribution assets grew 15.8% in 2025, against 9.4% for defined-benefit assets. [1]
The report links maturing pension systems with benefit payments, cash-flow planning and liquidity management. Its discussion of a Total Portfolio Approach and closer integration of investment teams is the authors' industry commentary, not a measured commitment across all ranked funds. [1]
A pension fund is not a family office with a larger portfolio. Its alternatives decisions relate to liabilities, cash requirements, governance and implementation capacity. See our article on liquidity in a diversified portfolio. Gnosis introduces institutional allocators to investment managers regulated in their home jurisdiction and evaluates those managers through Allocator IQ (AIQ). It does not advise on allocations, manage assets, hold custody or execute orders.
Frequently asked questions
What share of pension assets sits in alternatives?
The study does not give one figure for all pension assets. Among top-20 funds with available data, alternatives formed 23.9% of the simple-average portfolio and 17.3% on an asset-weighted basis.
Why do simple and asset-weighted averages differ?
A simple average treats each disclosed fund equally. An asset-weighted average gives more influence to the largest funds, which in the top 20 hold relatively less in alternatives.
Do North American pension funds hold more alternatives?
In the disclosed sample, North America-domiciled funds hold 36.3% in alternatives on an asset-weighted basis, against 14.7% in Europe and 10.5% in Asia-Pacific. Region refers to fund domicile.
Are pension and family-office allocations directly comparable?
No. The surveys use different categories, dates and weighting methods, and pension funds invest against liabilities. The figures are best read separately.
