# What Is Primary Fund Commitment?

> A primary fund commitment is an LP's pledged capital to a new venture or private equity fund—called over time via capital calls—rather than buying existing fund interests on the secondary market.

**Primary fund commitment** is capital an limited partner pledges to a newly raised fund vehicle—investing alongside the GP's fresh deployment period—distinct from secondary purchases of existing fund stakes.

### How it works

GPs fundraise by securing primary commitments in a [LPA](/glossary/lpa) framework. LPs commit amounts called over years as deals close. Fund size equals aggregate primary commitments (minus fees). Strong primary raises signal LP confidence and set [portfolio construction](/glossary/portfolio-construction) capacity.

Secondaries transfer LP interests in mature funds; primaries fund new company investments. Founders care indirectly: larger primary commitments enable bigger checks and reserves if strategy matches their stage.

### Why it matters

- **Founders:** Prefer funds actively deploying primary capital with dry powder—not secondary-only vehicles with different mandates.
- **Investors:** GPs track primary fundraising progress, LP mix (endowments, pensions, funds of funds), and re-up rates from prior funds.

### Common mistake

Assuming announced fund target equals committed capital—targets differ from final close until legal signing completes.

## FAQ

### What is primary fund commitment in simple terms?

It is money an LP promises to a brand-new fund that will invest in companies over the next years—not buying someone else's stake in an older fund.

### Why does primary fund commitment matter?

Fund size and LP base shape check sizes, follow-on capacity, and fund life. Founders benefit when GPs close strong primary commitments with aligned LPs.
