Global M&A Nears $4T as Megadeals Defy Geopolitics
Value up, volume down — megadeals carry a record-chasing M&A market through a year of geopolitical turmoil.
Global mergers and acquisitions are on track to reach roughly $4 trillion in total value in 2026. That’s up 13% from 2025 — only the second-highest spike to the pandemic-era peak of 2021 — that figure obscures a market increasingly defined by a handful of blockbuster transactions.
Deal volume data from PwC and LSEG projects an estimated 42,000 transactions for the full year, down 13% from 2025. Megadeals exceeding $5 billion account for roughly 48% of global deal value — up from 39% in 2025 and just 26% in 2024. Remove them from the equation, and overall deal value falls 4% year over year.
Headwinds likely stymied deal activity in specific sectors. The U.S.-Israeli military campaign against Iran, launched in late February, caused what the International Energy Agency called the largest oil supply disruption in the history of the global oil market, sending energy prices sharply higher.
Despite the recent U.S.-Iran memorandum of understanding to reopen the Strait of Hormuz, the conflict cast a pall over deal activity for much of the first half of the year, particularly for transactions with any exposure to energy, logistics, or the Gulf region.
Geographic Picture Remains Uneven
The U.S. has expanded its dominance, commanding 63% of global deal value in the first half of 2026, up from 54% a year earlier, even as deal volumes fell, according to Dealogic.
Europe’s share of value also increased by 88% ($733.6 billion), buoyed by large individual transactions. The Middle East and Africa, together, saw a 45% increase in deal value ($61.3 billion).
Asia Pacific moved in the opposite direction: its share of global deal value dropped to 29% — reflecting fewer megadeals and smaller average transaction sizes relative to the U.S. and EMEA.
On the advisory side, Goldman Sachs is leading the rankings by a wide margin — $1.161 trillion in deal value across more than 200 transactions so far this year. Among the firm’s marquee assignments: advising Dominion Energy on its $66.8 billion sale to NextEra Energy, counseling Unilever on its planned $65 billion food business merger with McCormick & Company, and serving as lead-left underwriter on the SpaceX IPO.
JPMorgan ranks second with $743 billion, up from $557.1 billion a year earlier — a performance the bank has attributed in part to M&A fees that nearly doubled year over year in the first quarter of 2026. Morgan Stanley rounds out the top three at $622.5 billion.
