Key Takeaways
- • MIT and Stanford lead Ivy returns at 14.8% and 14.3% respectively for FY2025, substantially outpacing their prior-year performance of 8.9% and 8.4%, driven primarily by strong public equity market performance and active management gains.
- • Eight of nine Ivy League endowments posted double-digit returns, with Columbia at 12.4%, Penn at 12.2%, Brown and Harvard tied at 11.9%, Yale at 11.1%, Princeton at 11%, and Dartmouth at 10.8%—representing meaningful year-over-year improvement across the cohort.
- • Private equity and illiquid assets remain a structural drag on overall endowment performance, with Columbia's investment chief explicitly noting that private investments "still lag public market performance" despite showing significant improvement versus prior years.
- • New federal endowment tax burdens have intensified operational pressures, with Harvard, Yale, Princeton, and Stanford now subject to an 8% tax rate, while Penn and Dartmouth face 4% rates, reducing capital available for reinvestment and compounding the drag from underperforming illiquid holdings.
- • The mismatch between liquid and illiquid asset returns exposes a fundamental portfolio construction challenge, with Yale's historical model of locking capital in private funds for extended periods no longer delivering the alpha premium that justified the illiquidity discount.
Summary
Ivy League endowments delivered solid investment returns for fiscal year 2025, with nearly all nine institutions posting double-digit performance driven by resilient public equity markets and successful active management execution. MIT and Stanford topped the peer group with net returns of 14.8% and 14.3% respectively, significantly ahead of their prior-year results. Columbia returned 12.4%, followed by the University of Pennsylvania at 12.2%, with Harvard and Brown each posting 11.9%. Yale, Princeton, and Dartmouth rounded out the cohort at 11.1%, 11.0%, and 10.8% respectively, while Cornell had not yet released its figures as of October 27, 2025.
Despite these headline returns exceeding prior-year performance across the board, endowment managers face a persistent structural headwind: the underperformance of private equity and other illiquid alternative assets relative to public markets. Columbia Investment Management Company President and CEO Kim Lew acknowledged this dynamic explicitly, noting that while "private investments saw a significant improvement versus the last few years … performance still lags public market performance." This divergence underscores a critical portfolio management challenge that has plagued Ivy League endowments throughout the extended period of private market underperformance.
Brad Conger, Chief Investment Officer at Hirtle Callaghan, characterized the operating environment as "a perfect storm of pinched operations and slower returns of capital than we thought," highlighting the dual pressures facing endowment portfolios. The private equity allocation remains the most acute concern for large institutional investors, as concentrated positions in illiquid funds continue to constrain overall returns despite the buoyant public market backdrop.
Adding to operational strain, newly implemented federal endowment taxation has materially increased cost structures. Harvard, Yale, Princeton, and Stanford now face an 8% tax rate on investment returns, while Penn and Dartmouth are subject to a 4% rate—a meaningful drag compared to the baseline 1.4% rate applicable to other Ivy institutions. These higher tax burdens directly reduce reinvestable capital and amplify the return headwind from private equity underperformance, limiting endowments' flexibility to rebalance away from struggling illiquid positions without triggering crystallized losses.
