The surge in private‑equity and private‑credit funds since the 2008 crisis has shifted $4 trillion of assets from banks to specialist “alternative” managers. The five largest U.S. alts—Blackstone, Apollo, KKR, Ares and Carlyle—now hold roughly $4 trillion in AUM, a five‑fold rise from $900 billion in 2015, challenging the $25 trillion US banking system benchmark.

Retail‑focused evergreen funds promise perpetual exposure to illiquid assets but limit quarterly redemptions to 5 percent, a rule that recent heavy withdrawal requests have tested. While disclosures can be thin, the liquidity caps are disclosed upfront, meaning investors can assess the trade‑off between access to private markets and reduced flexibility.

Cost remains the biggest hurdle. Public‑market fees have fallen to fractions of a percent, yet Blackstone’s B‑Cred charges 1.25 % management and 12.5 % performance fees, while KKR’s retail private‑equity product levies 1.5 % and 15 % respectively. These premium structures make private assets unattractive unless they deliver markedly higher returns.

If fee compression spreads across the alt sector, retail participation could rise, offering diversification beyond stocks and bonds. Until then, the market will likely remain dominated by institutional investors, and regulators will need to balance investor protection with access to this growing asset class.
