Global mergers and acquisitions reached a record $2.84 trillion in the first half of 2026, surpassing the previous record set in the first half of 2021. This surge represents a 49% increase from the same period last year, driven by U.S. tech companies' aggressive pursuit of dominance in artificial intelligence and related sectors.
Mega-deals, defined as those worth $10 billion or more, saw a significant increase, with 47 such transactions announced, a 62% rise from the prior year. Despite this, the total number of deals declined by 9%, indicating a market led by large-scale transactions rather than a broad increase in deal volume.
Regionally, the United States and Europe led the M&A activity, with U.S. deal volume up 77% and Europe up 105% year-on-year. In contrast, the Asia-Pacific region experienced a 2.4% decline in deal volume.
Analysts attribute the boom to a combination of factors, including the U.S. government's easing of antitrust regulations and the transformative impact of AI on industrial structures. The current "risk-on" environment is also seen as conducive to deal-making, with corporate boards actively exploring strategic options, including large-scale mergers.
Notable deals include NextEra Energy's acquisition of Dominion, driven by the surge in data center power demand due to AI proliferation, and SpaceX's $60 billion stock swap acquisition of AI coding startup Cursor. Industry officials emphasize a growing corporate recognition that strategic action is necessary to avoid the risks associated with inaction in a rapidly evolving landscape.
