Key Takeaways

  • Institutional pension funds currently allocate 8% to 15% of their capital to private equity, while retail investors sit between 0% and 1%.
  • Opening 401(k) and ERISA accounts to private markets introduces an individual investor capital pool larger than the entire institutional market.
  • Private credit can absorb massive capital expansions because lenders can scale from 1% to 10% of a large debt tranche without adding headcount.
  • Private equity faces strict structural capacity limits because underwriting, governance, and operational execution require human bandwidth per deal.
  • American Securities has maintained an average check size of $350 million to $400 million per deal for 15 years to stay inside its operational sweet spot.

The Liquidity Mismatch in Private Markets

Institutional investors have largely hit their target private equity allocations. Pension funds and sovereign wealth funds typically run between 8% and 15% of their total assets in private equity, averaging around 12%. Because these institutional balance sheets are mature, the next wave of capital is coming from retail investors, 401(k) accounts, and individual wealth platforms.

Michael Fisch calls this retail pool an incoming wave that dwarfs existing institutional assets: “This whole new set which is at zero and it's bigger than the entire institutional market, the individual investor market. So yes, it's a tsunami.”

Yet private equity is physically ill-equipped to absorb that scale of liquidity without breaking its investment models. While money can enter private market vehicles overnight, the supply of buyout deals that can generate target returns does not expand on demand.

Private Credit Scales with Capital; Buyouts Scale with People

The fundamental difference lies in asset class mechanics. Private credit managers can deploy larger pools of cash simply by taking bigger slices of existing corporate debt facilities. A debt fund can double its assets under management without doubling its headcount or changing its risk profile.

Fisch points out the contrast directly: “Whereas in private credit or debt, there's infinite amounts of debt out there in the world. There's companies that are issuing tons of debt and instead of being 1%, you can be two or five or 10% if you have more money. It's still 1% of your funds, but there's it's easy. The same people can invest a lot more money. Private equity is harder that way.”

Private equity buyouts cannot scale by writing larger checks into the exact same assets. In buyouts, control brings governance requirements, board seats, operating team involvement, and complex integration work. A buyout sponsor cannot double fund size without either moving up-market into fewer, larger auctions or hiring massive teams to execute more deals simultaneously.

American Securities has resisted that creep. The firm has kept its equity check size pegged to an average of $350 million to $400 million per transaction for fifteen years. Fisch targets the $200 million to $500 million equity segment because deal flow in that middle-market bracket remains deep and replenishable. Stepping above that tier forces firms to compete in hyper-efficient mega-cap auctions where alpha shrinks.

“As a general rule, private equity really different than private credit and some other things,” Fisch notes. “It can only grow so fast. You just can't add lots of assets in private equity.”

Why It Matters

Retail capital inflows will flood private credit and mega-cap infrastructure vehicles first because those products offer the liquidity and deployment velocity needed to absorb billions. Middle-market buyout funds that attempt to capture this retail wave face severe style drift, asset bloat, and compressed net IRRs. The firms that preserve top-quartile performance will protect their check sizes, cap fund growth, and leave excess retail demand to yield strategies.
