Global private equity M&A posted 614 transactions in the first quarter of 2026 — down 22% from 785 in Q1 2025 — while aggregate deal value climbed 12.6% to $154.6 billion. The math behind that combination is not complicated once you know where the money went. A record cluster of megadeals at the top of the market generated enough value to more than offset the decline in mid-market and small-cap activity.

Fewer Deals, Bigger Average

The arithmetic of Q1 PE is stark. With 171 fewer transactions but 12.6% more total value, the implied average deal size rose substantially. LSEG and Reuters confirm 22 individual transactions above $10 billion — a record for any quarter — and those deals alone represent a significant fraction of the $154.6 billion aggregate. The OpenAI and Anthropic equity rounds contributed to the total, as did a series of large industrial carveouts and software buyouts executed by the biggest PE sponsors.

Six of the eight largest PE sponsors by AUM expanded committed capital in Q1. Their deployment activity is concentrated in deals where competition is limited to a handful of global peers, underwriting timelines are longer, and the LP relationships sustaining those capital bases are with institutions that haven’t meaningfully reduced private markets exposure. That combination — deep capital, stable LP base, high entry prices — defines the winning formula at the megafund level in the current environment.

The Simple Reason Mid-Market Volume Is Down

In the middle of the market, the deal math does not work for buyers at seller-expected prices. Sellers bought or built assets during years of cheap debt and high exit multiples. Buyers today face floating loan rates above 6% on leveraged credit, public comparable multiples that have re-rated downward, and LP base return expectations that haven’t moved to accommodate a lower-return environment. Linklaters partner Florent Mazeron described the resulting bid-ask spread on an April analyst call as the widest since 2023.

Neither side is irrational. Both can wait. The transactions that did close at mid-market sizes in Q1 were cases where waiting was more expensive than transacting — corporate sellers with earnings pressure, funds approaching deployment deadlines, or tech companies facing competitive windows that would not stay open.

LP Behavior Adds a Capital Constraint

The mid-market PE slowdown has a capital dimension beyond valuation. Smaller institutional LPs — regional pension funds, community foundation endowments, sub-$5 billion family offices — reduced private markets allocations through 2025. Of the 20 PE sponsors by AUM below the top eight, only nine grew committed capital in Q1, and median check size fell. New fund formation at mid-market firms has slowed, compressing dry powder precisely where deal flow would otherwise require it.

What Rate Clarity Would Change

The Federal Reserve’s April 24 decision produced a split vote on H2 2026 rate cuts. Ambiguity about forward rates forces sponsors to build extra risk premium into every underwriting model, effectively reducing the price they can pay for any asset and widening the bid-ask gap further. M&A advisors consistently estimate 50 to 75 mid-market transactions in a holding pattern, waiting for a clean rate signal that would, within 90 days, close those deals. Five PE-backed IPOs priced above range in Q1; sustained exit performance through May and June would support a volume recovery in Q3, assuming the Fed provides the rate clarity the market needs.
