How big is MIT's endowment in 2026?

MIT's endowment funds totaled $29.2 billion, excluding pledges, at the end of fiscal 2026 on June 30, 2026, according to MIT News (Oct. 2, 2026). That is a record and up from $27.4 billion a year earlier. MIT remains one of the largest university endowments in the United States.

What return did MIT's endowment earn in fiscal 2026?

MIT reported a 10.3% investment return for the year ending June 30, 2026, down from 14.8% in fiscal 2025. Bloomberg noted that this trailed the 18.9% median return before fees for large endowments tracked by Wilshire TUCS, and well behind Harvard's 27.1% and Stanford's 31.7% for the same period.

Why did MIT's endowment trail its peers in 2026?

MIT has not said. Bloomberg reported on October 2, 2026 that MIT declined to provide details on what drove its fiscal 2026 performance. Without a published asset-class breakdown, any explanation is speculation; the peer pattern suggests that portfolios with larger venture and growth-equity weights captured more of the year's gains.

What is MIT's long-term endowment return?

Over the 10 years ending June 30, 2026, MIT generated an annualized return of 11.7%, up from 10.7% for the decade to June 2025, per MIT News. That compares with a 10-year figure of 12.5% for Stanford's Merged Pool and 9.4% for Yale's endowment to June 2025, keeping MIT near the top of the long-run table.

Who manages the MIT endowment?

The endowment is managed by the MIT Investment Management Company (MITIMCo), which MIT describes as a unit of MIT created to manage and oversee the investment of the Institute's endowment, retirement and operating funds. MIT publishes little detail about portfolio holdings in its annual release, so outside analysis of its returns is limited.

What does MIT's endowment pay for?

MIT says it uses the bulk of the income its endowed gifts generate for financial aid, research and education. In its fiscal 2025 release MIT said the endowment supports 50% of undergraduate tuition. MIT does not publish its distribution amount in the annual endowment release; detail is in the Treasurer's Report.

MIT Endowment 2026: Size, Return and Peer Comparison

Answer

MIT's endowment reached a record $29.2 billion (excluding pledges) at June 30, 2026, after a 10.3% return for fiscal 2026. That was well behind Harvard's 27.1% and Stanford's 31.7%, and below the 18.9% median for large endowments. But MIT's 10-year annualized return improved to 11.7%, one of the best long-run records among US universities. One weak year next to peers does not undo a strong decade.
