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 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 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.
