Private Market ETFs: Democratizing Access

Private markets were historically for institutional and ultra-high-net-worth investors. Today, that exclusivity is breaking down, as many retail investors realize the value behind private markets and advisors look for additional diversification tools. Outside of other structures like interval funds and feeder funds, ETFs remain a convenient and familiar choice.

What’s Driving the Push for Democratization?

Public markets have become more concentrated (just think about the technology tilt of broad equity indexes — the GICS technology is over 1/3 of the S&P 500), which makes owning the market feel less comprehensive than it used to. Private markets can offer exposure to diverse opportunities and the potential for excess returns. A key feature is the illiquidity premium. Illiquidity is not necessarily a bad thing if you have a tolerance for long-term time horizons. Markets often reward investors for locking up capital over long-term time horizons rather than panic selling before investment themes materialize.

The ETF Wrapper Is Still Crucial to Understand

Private markets aren’t just private versions of stocks and bonds. They come with different mechanics and valuation methods. Democratization is an attempt to translate those mechanics into something more accessible while still making sense for the wrapper.

That’s why the most common structures have been semi-liquid registered structures like interval funds rather than ETFs. Interval funds are designed to hold more illiquid assets. In exchange, they do not offer daily liquidity (instead, repurchases happen at preset intervals and in limited quantities). And that’s also why one of the biggest questions now is: How far can you push private assets into vehicles that investors expect to behave like ETFs?

Still, you can’t ignore ETFs as an important part of this industry. After all, many investors and advisors are more familiar and comfortable with the ETF structure. Several ETFs have taken indirect routes through equity investments of private managers or through ETFs of BDCs. Meanwhile, a milestone launch of the SPDR SSGA Apollo IG Public & Private Credit ETF (PRIV) in February 2025, due to the higher limit of private market securities, was made possible through a relationship with Apollo.
