- Public equities have repriced the future while private equity is still monetizing the past. Since the October 2022 trough, the S&P 500 has compounded at more than 20% a year for three straight years, while Private Equity buyout portfolios assembled at the 2020-2021 peak, and now carrying more expensive debt into a thin exit market, have lagged on every benchmark and horizon. At this point in time, the gap between liquid and illiquid equity returns seems to be the widest in two decades.
- The rally that opened the gap is narrow and earnings-led, not a liquidity melt up. The Magnificent Seven alone delivered more than half the S&P 500's three-year total return, strip them out and the index is an ordinary performer, and the equal weighted version has compounded at about half the pace, a gap unseen since the late 1990s. But the move rests on delivered earnings and a real AI capex super cycle rather than multiple expansion, so the premium looks more durable than the dot-com peak.
- Yet private equity's long-run premium is real, this cycle has just interrupted it. On a like for like basis, matched to public indices for geography, size, sector and leverage and net of fees and carry, buyout has beaten public markets over three decades, with MSCI estimating pooled direct alpha of roughly 400bps a year since 1994. The exception is the 2021-2023 vintages, which currently show a negative direct alpha of about ~800bps against the MSCI ACWI, the first consecutive run to trail public markets in the series. Consequently, the data points to rough PE performance ahead even allowing for the fact that these vintages are still young and J-curve distorted.
- Private equity can no longer count on rising valuations and must now drive returns by growing the underlying business. For over a decade, buyout returns came mostly from rising valuations, selling companies for a higher multiple than was paid. That is mostly gone as borrowing costs have roughly doubled and exit valuations have stopped climbing, so returns now come from growing the business. The contrast on the financing side is also large, with the largest listed companies still holding more cash than debt, so benefiting from higher rates, while buyout owned companies sit on floating rate debt due to be refinanced in 2026-2028, where higher rates only add to their interest bill.
- As capital drains from private equity, private debt is catching the outflows. The same jump in interest rates that made buyout deals more expensive made lending the more attractive trade. Big long term investors continue to like senior private credit because it pays a steady, contractual cash yield, its value barely moves and losses have been low, none of which buyout has delivered lately. So new money is rotating out of private equity and into private debt.
- 2026 will decide whether the public-private gap was a passing extreme or a lasting regime change. Our central case assumes an economic mix that keeps returns positive but well below the post-Covid peaks with public equity settling in the low teens, while buyout follows in the mid-teens through 2027-2028. All in all, the way forward for private equity seems to be less about how much to own and more about how to own it. This means favoring managers and vintages with a demonstrable edge over generic exposure, treating liquidity and valuation discipline as features to be tested rather than assumed and resisting the temptation to buy the label without the underlying skill.
