Strong M&A momentum through mid-2026, with global announced deal value on pace for roughly $4 trillion—the highest since 2021—has been propelled by megadeals exceeding $10 billion that now account for nearly half of total volume. AI infrastructure needs, energy demand for data centers, life-sciences patent cliffs, and corporate portfolio simplification are driving strategic buyers and private equity toward scale-enhancing acquisitions, supported by elevated equity markets, available balance-sheet capacity, and a relatively accommodative regulatory backdrop. Cross-border activity has risen sharply, particularly into the U.S. and EMEA. With the year-end window short and many announced transactions still pending regulatory or shareholder approvals, near-term closings will hinge on swift resolution of antitrust reviews and financing conditions amid ongoing volatility.
