$100 Million, $1 Billion or $10 Billion Portfolios: How Much Should Institutions Allocate to Venture Capital?
Yale's FY2025 endowment update shows how large institutional pools can support long-duration investment plans. Very large endowments combine long-term investing with recurring institutional spending. Venture allocations should be reviewed against the whole institution, rather than the return target alone.
Yale reported a $44.1 billion endowment value at June 30, 2025, after $2.1 billion of budget distributions.
A sample institutional portfolio shows venture capital at ten percent and all other assets at ninety percent.
A 10% Venture Target in Context
A 10% policy target may look modest, but at institutional scale it can represent a full venture programme.

| Portfolio segment | Share | How to read it |
|---|---|---|
| Venture capital | 10% | Target allocation that becomes materially different at larger portfolio sizes. |
| Other portfolio assets | 90% | Public markets, credit, real assets, cash, and other alternatives. |
Scale Changes the Routes Available
Portfolio size affects how an institution can build venture, but it does not produce one correct percentage. A $100 million portfolio may need a small number of pooled relationships. A $1 billion portfolio can diversify across managers and vintages. A $10 billion portfolio may add separate mandates, co-investments, and internal staff. The target should come from liquidity, return needs, minimum commitment sizes, and the institution's ability to select and monitor managers.
Scale Changes the Available Routes
| Portfolio size | Likely access routes | Main constraint |
|---|---|---|
| $100M | Fund of funds, pooled vehicle, or a small set of direct funds | Minimum commitments and staff time |
| $1B | Direct funds across vintages, selective co-investments, and specialist mandates | Building enough manager depth without overdiversifying |
| $10B | Multiple managers, separate accounts where available, co-investments, and secondaries | Deploying meaningful dollars without lowering selection quality |
Percentages Can Hide the Dollar Problem
A 5% target equals $5 million in a $100 million portfolio and $500 million in a $10 billion portfolio. The smaller investor may struggle to meet manager minimums. The larger investor may struggle to find enough high-quality capacity without owning too much of any fund. The institution should therefore model commitment sizes, expected calls, and look-through company exposure. The same percentage creates a very different programme at each scale.
Build Gradually
A new programme should not reach its long-term target in one year. Commitments take time to call, and vintage diversification takes several years to build. Rushing can concentrate the portfolio in one pricing and fundraising cycle. A pacing plan should state the annual commitment range, number of new and re-up managers, and conditions that would slow or increase commitments.
Scale Should Improve, Not Weaken, Selection
Large investors may receive co-investment access and stronger information rights, but larger cheques can also push them toward bigger funds. The institution should test whether those funds still offer the stage, ownership, and return profile the allocation is meant to provide. Small investors may gain broader access through a fund of funds but pay an extra fee layer. The comparison should be net of all costs and include the internal resources saved.
What the Policy Should Cover
- Target and range: Allow the allocation to move with markets.
- Set commitments by vintage rather than only a final percentage.
- Limit dependence on one firm or strategy.
- Identify the assets that cover capital calls.
- Access routes: Explain the roles of funds, co-investments, secondaries, and pooled vehicles.
The useful question is not how much a portfolio of a certain size should allocate. It is which programme can use that amount well and continue funding it through a weak market.
Translate Percentages Into Dollars
A 10% venture allocation equals $10 million on a $100 million portfolio, $100 million on a $1 billion portfolio, and $1 billion on a $10 billion portfolio.
Mercer noted that FY25 NACUBO/Commonfund respondents targeting nominal returns averaged 7.3%, with the largest institutions targeting 8.1%. Venture sizing should be tied to the role the allocation plays in reaching the total portfolio target.
Implementation Capacity Matters
A $100 million portfolio with a 10% venture allocation has a $10 million allocation, enough for one focused institutional commitment before reserves. A $1 billion portfolio at the same 10% target has $100 million and can support 10 equal $10 million manager relationships.
Five, ten, and fifteen percent venture allocations produce very different dollar exposures across $100 million, $1 billion, and $10 billion portfolios.
Allocation Dollars by Portfolio Size
The same policy percentage can imply a small allocation, a full portfolio, or an institution-scale venture platform.
| Portfolio size | 5% venture | 10% venture | 15% venture |
|---|---|---|---|
| $100M | $5M | $10M | $15M |
| $1B | $50M | $100M | $150M |
| $10B | $500M | $1B | $1.5B |

Frequently Asked Questions
Should a smaller institution avoid venture?
No, but it should be selective: A smaller portfolio may need fewer relationships, a specialist fund of funds, or a slower build-out.
Can a large institution allocate too little to venture?
Yes: If the dollar amount is too small to quality of access managers or influence total portfolio outcomes, the allocation may add complexity without enough impact.
