Harvard's endowment closed out fiscal year 2026 at a record $68 billion, swelling by $11 billion after a blockbuster 27.1 percent investment return. The gains came even as the university faces a steeper federal tax bill that could start chipping away at those returns as soon as next year.
The endowment was valued at $68 billion on June 30, 2026, according to Harvard Management Company, which oversees the university's investment portfolio. As Bloomberg reported, the fund made successful bets on equities and venture capital and benefited from broad stock-market gains and its hedge-fund portfolio, pushing it to a new record. Harvard Management Company has managed the university's endowment portfolio since 1974 and oversees roughly 15,000 individual funds invested as a single entity, per the school's own financial office.
SpaceX Bet Stands Out Among Holdings
Among Harvard's disclosed public-equity positions, one stands well above the rest. Harvard disclosed a $2.2 billion stake in SpaceX as of June 30, 2026, making it the endowment's largest single public-equity holding, according to CB Insights. The fund's broader performance was also helped by what Bloomberg described as successful bets on equities and venture capital more generally, consistent with Harvard Management Company's generalist investment model and long-term outlook.
Harvard's endowment has posted an annualized return of approximately 11 percent per year since Harvard Management Company's founding, the firm says. That track record helps explain why the fund has become so central to the university's finances: in fiscal 2026, distributions from the endowment contributed nearly 40 percent of Harvard's operating revenue, per the same Harvard Management Company account. The $2.6 billion endowment distribution now makes up nearly 40 percent of operating revenue, the Crimson's reporting confirms, with Harvard also posting a $100 million operating surplus on $6.7 billion in revenue for the year.
How Harvard Stacks Up Against Peer Schools
Harvard's roughly 27 percent return was strong, but it wasn't the best among its peers. Stanford reported a 31.7 percent return, while the University of Pennsylvania returned 27.4 percent, according to the Crimson's review of fiscal 2026 results. MIT's endowment stood at $29.2 billion.
Princeton, which operates on a slightly different fiscal calendar, reported an 11 percent return on investments for its 2025 fiscal year, with its endowment reaching $36.4 billion, according to the Princeton Alumni Weekly. That Princeton figure sat close to the median for the 39 college and university endowments tracked by Pensions & Investments, which stood at 10.8 percent as of Oct. 24, per the same Princeton Alumni Weekly report.
A Tax Hike Could Reshape the Picture
None of this year's gains are guaranteed to stick around in their current form. Harvard's own finance office says a federal bill passed in 2025 raised the endowment excise tax rate from 1.4 percent to a tiered rate as high as 8 percent for affected institutions such as Harvard, according to the university's endowment tax FAQ page.
That increased rate is set to take effect in fiscal year 2027, the university states. The tax applies to investment income.
A Broader Slowdown in Gifts
Harvard's investment windfall arrives against a backdrop of softening charitable giving across higher education. New gifts for all participants in a national endowment study declined 9.2 percent to just under $14.0 billion in fiscal 2025, down from $15.4 billion the prior year, according to NACUBO. At the same time, participating institutions withdrew $33.4 billion from their endowments in fiscal 2025, an 11.0 percent year-over-year increase, and endowments funded an average of 15.2 percent of those schools' annual operating expenses, up from 14.0 percent a year earlier.
Private equity was the largest dollar-weighted allocation among those study participants at 16.8 percent, followed by marketable alternatives at 15.4 percent, NACUBO found. Harvard is navigating both a historic return and a less certain tax landscape ahead.
