Global M&A Falls Below $1 Trillion in Q3, Annual Record at Risk
nashnova research
Global M&A dropped to $986 billion in Q3 2026, the first sub-trillion quarter since the trade war began, effectively ending hopes of a full-year record. High interest rates and AI uncertainty are squeezing mega-deal appetite simultaneously.
How steep was the drop?
Q3 global M&A totaled $986 billion, down sharply from last quarter's near-record $1.7 trillion and 13% lower year-on-year.
The first three quarters sum to $3.9 trillion, below the ~$4.2 trillion logged over the same period in 2021. This means → even a strong Q4 cannot close the gap to a new annual record.
Mega-deals above $10 billion fell to just 10, down from 26 last quarter. In plain terms = dealmakers still want to transact, but the biggest deals are stalling.
What is holding deals back?
High interest rates are the first constraint. Post-Iran-war inflation-fighting rates have pushed up financing costs for large acquisitions.
AI disruption is the second. Rapid adoption is reshaping business models, making it harder for buyers to price a target's future. This means → acquirers are not walking away — they cannot agree on what anything is worth.
Aaron Gruber, co-head of global M&A at Cravath, put it this way: "Boards and management teams are spending more time assessing risk, which slows deal pace — but they still lean toward action."
Which marquee deals landed — and which collapsed?
Notable Q3 closings: Aon acquired KKR-backed insurance broker USI for $17 billion; Uber bought Germany's Delivery Hero for €13 billion; former Disney CEO Bob Iger and investor Josh Kushner paid $12.5 billion for the NBA's Los Angeles Lakers.
Notable Q3 collapses: AstraZeneca scrapped a $400 billion merger plan with Bristol Myers Squibb; Honeywell spinoff Solstice Advanced Materials withdrew a $14.5 billion cash-and-stock bid for Element Solutions after lukewarm investor response.
This reflects the quarter's defining pattern — as Lorenzo Corte, head of global deals at Skadden, noted: "Fewer deals, bigger checks — this is not a market where you spend casually."
What comes next?
The November U.S. midterm elections are now the key variable for deal pace. A Democratic win in one or both chambers could tighten antitrust enforcement.
This means → some companies may rush to close deals while the current, relatively permissive window remains open. Ian Nussbaum, partner at Latham & Watkins, said: "There is a willingness to capitalize on what is perceived as a more M&A-friendly U.S. environment."
Jefferies global investment-banking head Raphael Bejarano offered an alternative view: a divided-government outcome could actually support economic stability and accelerate M&A activity in 2027–2028.
