Q4 2025: what happened

Global dealmaking ended 2025 with a megadeal-led surge. Multiple trackers put total 2025 M&A value around the mid-$4T range (roughly $4.5T–$4.8T), making it one of the strongest years on record by value.
S&P Global’s Q4 2025 review highlighted that large deals ($10B+) were the key driver of performance, with 51 deals totaling about $1.1T in 2025 and the most $10B+ activity since 2021.
The market dynamic was “top-end strong, broader volume mixed”: megadeals thrived while smaller-deal activity was comparatively weaker.

Early Q1 2026: what the market is signaling right now

Europe showed a softer start: S&P Global’s Europe Q4 2025 recap (published Feb 2026) reported year-over-year declines in both deal value and volume, reinforcing that the rebound is not uniform by region.
Bottom line: the market is open for well-positioned, strategic transactions, but execution certainty and deal quality are the differentiators.

2026 projections: where consensus is leaning

Most outlooks converge on “momentum continues, but selectively.” Bain’s 2026 outlook notes that a large majority of M&A executives expect to sustain or increase activity in 2026, with technology disruption, geopolitics, and portfolio reshaping as core drivers—and accelerating AI adoption inside deal processes.
Reuters reporting from early January 2026 describes a “bulging pipeline” narrative among top deal lawyers after a deal-crazed 2025, with optimism tied to financing conditions and continued appetite for complex, large transactions.

ALS framing

2026 is shaping into a conviction market: fewer, larger, more strategic deals; more complex structures; and a widening valuation gap between premium assets and everything else. Winners will be the buyers and sellers that engineer certainty—clean diligence, bankable financing, and clear strategic rationale.
