Princeton’s investment office, Princo, maintains substantial exposure to equities and equity-like assets, which represented 94% of the portfolio in its fiscal 2025 disclosures.
Private equity accounted for more than $14 billion, including investments in private companies and venture capital. Another $8.7 billion was allocated to “independent return” strategies, including long/short equity and event-driven investments. The program also includes real estate and natural resources.
The university has not disclosed fiscal 2026 asset-class returns or an updated allocation, limiting conclusions about which strategies drove the gain.
Despite the strong year, Princeton continues to plan around an 8% long-term investment return. Endowment distributions are projected to cover 65% of Princeton’s fiscal 2027 net operating budget, making sustained performance central to funding teaching, research and financial aid while maintaining financial flexibility over time.
