Global M&A Activity Hits Record $2.85 Trillion in H1 2026

$2.85 trillion in six months is not a recovery story. It is concentration. LSEG data cited by Investment Executive shows global M&A value hit a first-half record in 2026, up 50% year over year, while the number of transactions fell 9%. For founders, boards, and corporate development teams, the signal is blunt: capital is moving, but it is moving toward scale, control, and balance-sheet logic.

The market is bigger, not broader

The first-half total reached $2.85 trillion, the highest first-half figure on record, according to LSEG data reported by Investment Executive. The second quarter alone reached $1.6 trillion, up 31% from the first quarter and also described as a quarterly record.

The driver was not a flood of small deals. It was the opposite.

LSEG counted 48 mega deals — transactions valued at $10 billion or more — totaling $1.3 trillion in the first half. That is the real market structure. Fewer deals. Larger checks. More power in the hands of buyers that can finance size, absorb integration risk, and justify board-level strategic moves.

For startups, this matters because “M&A market is hot” is the wrong takeaway. The market is liquid at the top. That does not automatically improve exit odds for thinly differentiated companies, subscale software portfolios, or venture-backed teams still selling a growth narrative without margin evidence.

The useful question is narrower: can the asset become strategic enough to enter a buyer’s priority stack?

Tech is the main battlefield

Technology led sector activity, accounting for 24% of global M&A deal value in the first half, according to the same LSEG data. Tech M&A value rose 90% from 2025. Industrials rose 57%. Energy and power gained 41%.

That mix tells us where boards are allocating capital. Buyers are paying for technical capability, infrastructure, and operating leverage — not pitch-deck vocabulary.

The regional split is also clear. Deals involving U.S. targets accounted for $1.5 trillion, or 54% of global M&A value, up from 45% last year. U.S. dealmaking value rose 80% compared with the first half of 2025. European M&A reached $676 billion, more than double the same period last year. Asia Pacific was weaker, with dealmaking down 2% to $360 billion.

Korea is a useful micro-signal. Seoul Economic Daily reported that completed Korean M&A deals reached 244 transactions worth 46.9796 trillion won in the first half, up 65.5% from 28.3945 trillion won across 222 transactions a year earlier. The reported drivers were major conglomerates expanding into new businesses, divesting non-core operations, and global private equity funds moving into Korea’s AI-related value chain.

But even there, the caveat is material: on an announcement basis, first-half Korean deals totaled 57 transactions worth 20.0624 trillion won, which the report said could point to a softer second half. Completed deals and announced deals are not the same liquidity signal.

What operators should check now

This market rewards preparation, not hope. If a company expects M&A to be an exit route, the board should run a hard readiness review now:

• Buyer map: identify strategic acquirers with active capital allocation in tech, industrials, or energy and power. Generic “big tech may buy us” thinking is not a plan.
• Control logic: define what the buyer gets that it cannot build fast enough. Product overlap is not enough. Distribution, data, infrastructure, or regulated capability matters more.
• Financial hygiene: clean revenue quality, customer concentration, deferred revenue, retention, and cost structure before a process starts. Buyers punish mess.
• Integration risk: document systems, contracts, security posture, and technical debt. Large acquirers price friction.
• Timing discipline: do not confuse record aggregate value with broad exit availability. The deal count is down.

Advisor league tables also show where large mandates are clustering. Investment Executive, citing LSEG, reported Goldman Sachs at 38.4% global advisory market share, followed by Morgan Stanley at 24.2% and JP Morgan at 24.1%. That concentration is another signal: the largest transactions are being run through a narrow set of institutions.

Verdict: the first half of 2026 is a strong M&A tape, but not a forgiving one. Scaled strategic assets have leverage. Everyone else still needs proof.
