StepStone Group has closed its infrastructure secondaries fund, raising a total of $1.7 billion across the fund and related separate accounts.
The closing adds substantial new capital to StepStone Group’s infrastructure secondaries strategy as institutional investors continue looking for opportunities to access mature private infrastructure assets through the secondary market.
Infrastructure secondaries involve purchasing existing interests in private infrastructure funds, portfolios, or individual assets from investors or sponsors seeking liquidity. Rather than committing capital exclusively to newly formed funds, secondary investors can acquire exposure to investments that are already partway through their holding periods.
That structure can provide investors with greater visibility into the underlying assets than may be available when committing to a traditional blind-pool fund at inception.
Infrastructure assets can include businesses and projects across areas such as transportation, energy, utilities, digital infrastructure, and other essential services, although StepStone did not disclose the specific sectors or assets the newly closed strategy will target.
The $1.7 billion total includes capital raised through the main infrastructure secondaries fund as well as related separate accounts.
Institutional investors may use secondary sales to generate liquidity, rebalance private market portfolios or reduce exposure to particular funds or vintages. At the same time, fund managers can use secondary structures to extend ownership periods or provide liquidity alternatives around existing investments.
For buyers, these transactions can create opportunities to acquire interests in established portfolios where more information is available regarding asset performance, capital deployment, and remaining investment duration.
Infrastructure can be particularly suited to secondary strategies because many assets are held for extended periods and can generate relatively long-duration investment exposure.
The latest closing expands the amount of capital StepStone Group has available to participate in this market and gives the firm additional flexibility to evaluate opportunities across fund interests and other infrastructure-related secondary transactions.
At $1.7 billion across the fund and related accounts, StepStone now has a sizable amount of fresh capital dedicated to infrastructure secondaries as private market investors increasingly look for liquidity solutions and alternative ways to gain exposure to established infrastructure portfolios.
The closing further strengthens StepStone Group’s position in the broader private markets ecosystem, where secondaries have become an increasingly important source of liquidity for investors holding otherwise long-duration private assets.
