Should universities prioritize high-growth, risky investments for their endowments to fund local academic programs?

Washington University intends to sell its SpaceX holdings, which currently represent 10 percent of the school's total endowment, over the next several years. The move follows a surge in the university's endowment value to $17.7 billion in fiscal year 2026.

Why it matters

The divestment strategy aims to achieve a more diversified portfolio while generating liquidity to increase spending on academic priorities like scholarships and professorships. The university must also manage the financial impact of a new federal excise tax on its net investment income.

Washington University's endowment grew to $17.7 billion in fiscal year 2026, with 63 percent of funds being donor-restricted. The institution faces a 4 percent excise tax rate on net investment income under the One Big Beautiful Bill Act.

The players

Washington University

A prominent private research institution located in St. Louis that manages a multibillion-dollar endowment to support academic operations.

SpaceX

A major aerospace manufacturer and space transportation company that went public in June 2026.

The details

The university originally invested approximately $50 million in SpaceX in 2017, and the company later went public in June 2026 at $135 per share. Most of the stake is held through a fund managed by external partners, and the university employs a hedging strategy to safeguard gains.

SpaceX completed its initial public offering in June 2026 at $135 per share.
The university endowment reached a value of $17.7 billion during fiscal year 2026.

Market Dynamics

The university's decision to offload its large SpaceX position reflects a necessary adjustment to the tax landscape created by the One Big Beautiful Bill Act. By rebalancing away from a concentrated asset, the institution aligns its investment strategy with new federal excise tax realities.

The shift in endowment strategy may impact future academic resources and scholarship funding availability for the university community. Investors tracking the university's moves may monitor how large institutional holders react to tax policy changes under the One Big Beautiful Bill Act.

The takeaway

Large institutional investors often use hedging strategies to manage risks when holding concentrated positions in public companies. Diversification remains a key tool for institutions looking to protect gains while meeting rising regulatory and operational financial obligations.
