The equity rounds for OpenAI and Anthropic — two of the largest private capital raises in technology history — were counted within the PE-adjacent deal universe for Q1 2026, and their scale helped push aggregate PE M&A value to $154.6 billion, a 12.6% increase year on year. Total transaction count fell from 785 to 614, a 22% decline. The quarter was simultaneously historic at the top and deeply quiet in the middle.
Why the AI Rounds Count as PE Activity
LSEG’s categorization of the OpenAI and Anthropic fundraises within the PE-adjacent bucket reflects a deliberate analytical judgment: the investors providing that capital — sovereign wealth funds, large institutional LPs, and several of the eight biggest PE sponsors by AUM — are treating these positions as core portfolio holdings, not sidecar bets. The return thesis, the hold period expectations, and the capital scale are consistent with private equity logic even if the deal structure differs from a traditional leveraged buyout.
That broadened definition of PE activity is one reason the aggregate value figure can tell a story of growth even when the traditional buyout count is declining. Reuters and LSEG confirmed 22 transactions above $10 billion in Q1 — a record — with AI, software, and large industrial carveouts filling the list alongside the technology equity rounds.
The AUM Data Tells the Distribution Story
S&P Global Market Intelligence AUM data for the quarter is precise about where capital is and isn’t flowing. Six of the eight largest PE sponsors by assets under management grew committed capital in Q1. Among the next 20 by AUM, only nine did, and the median check size in that cohort fell. Below those 28 firms, mid-market and lower-middle-market sponsors are running at deal volumes not seen since early 2020.
Florent Mazeron of Linklaters, speaking on an April analyst call, framed the standoff clearly. The bid-ask spread between PE buyers and sellers — the gap between what sellers will accept and what buyers can pay at required returns — is at a three-year high. Sellers set expectations during 2020–2022; buyers are underwriting to 2026 conditions. Both can wait. The deals that clear are the ones where waiting is more expensive than transacting.
Sectors Where the Market Didn’t Pause
AI infrastructure was the exception to the volume slowdown across all deal sizes. The strategic imperative driving AI acquisitions is partially disconnected from interest-rate math: buyers fear missing a window, not just paying too much. Several sub-$1 billion AI software and data infrastructure transactions closed in Q1 at multiples that would have been rejected in other categories, because the acquirers’ competitive logic overrode their return-threshold discipline.
The Second Half Depends on Two Variables
The Federal Reserve’s April 24 vote split on the pace of H2 2026 rate cuts, adding scenario risk to every LBO model and keeping the bid-ask spread wider than it would otherwise be. Deal-market advisors estimate 50 to 75 transactions are queued for rate clarity. A decisive cut would release them within a quarter.
Exit data from May and June will provide the complementary read. Five PE-backed listings priced above range in Q1. A continuation of that performance improves portfolio economics for mid-market GPs, creates LP confidence in private markets returns, and builds the conditions for a volume recovery in Q3. The bankers who told LPs to expect flat 2026 deal flow are not yet revising publicly — but several are adjusting their private scenarios.
