Mergers and acquisitions (M&As) in the U.S. - statistics & facts
Mergers and acquisitions (M&As) have long been a key driver of corporate growth and market consolidation in the United States. This helps companies come together in a way that makes them more efficient, taking advantage of economies of scale and scope. From small startups to Fortune 500 companies, M&As have proven to be a versatile tool for growth and survival in a competitive business environment. In 2025, the value of M&A deals in the U.S. surpassed 2.5 trillion U.S. dollars, making it the second-highest annual total since 2006.
A sharp rebound after years of decline
The number of M&A deals in the U.S. stood at roughly 16,700 in 2025, well below the 2021 peak of more than 25,000 transactions. Yet total deal value rebounded sharply, global M&A value topped four trillion dollars in 2025, with North America accounting for the majority of this total. Among the biggest U.S.-targeted transactions were Paramount Skydance's acquisition of Warner Bros. Discovery and Union Pacific's takeover of Norfolk Southern.
Tech, pharma, and financial services at the forefront
Technology, media, and telecom (TMT) remained the top sector by both value and volume. Inbound U.S. TMT deal value exceeded one trillion U.S. dollars in 2025, while domestic U.S. TMT deals reached well over 864 billion U.S. dollars. The business services, pharma, and energy sectors also saw significant activity. Within financial services, capital markets captured roughly 61 percent of deal value, far outpacing banking and insurance. The largest financial services deal of 2025 was Global Payments' divestiture of its Worldpay unit.
Wall Street's go-to dealmakers
Many of the world's leading investment banks advise on M&A deals, which serve as a significant revenue stream. In 2025, the leading financial advisor to U.S. M&A deals was Goldman Sachs, which advised on transactions worth more than one trillion U.S. dollars. JPMorgan and Morgan Stanley rounded out the top three. The widening gap between fewer deals and higher aggregate value may suggest that consolidation is increasingly driven by blockbuster transactions rather than broad-based deal flow, a trend likely to intensify if regulatory conditions remain favorable.
What's next for U.S. dealmaking
The momentum behind large-scale consolidation shows no signs of slowing. North American M&A deal value nearly doubled between 2024 and 2025, jumping from roughly 1.9 trillion to 3.2 trillion U.S. dollars, accounting for the largest portion of global M&A deals. With trends including AI-driven acquisitions, ongoing fintech consolidation, and cross-sector plays such as the Union Pacific's rail deal, reshaping the landscape, the U.S. is well positioned to remain the world's most active M&A market. Whether deal volume catches up to deal value will depend largely on interest rate trajectories and regulatory clarity heading into 2027.
