Global mergers and acquisitions reached a record $3.16 trillion during the first six months of 2026, driven by an unprecedented wave of multibillion-dollar takeovers as companies raced to gain scale in an increasingly competitive global economy. According to a July 8 report from Mergermarket, the deal-tracking arm of ION, worldwide M&A value jumped 44 percent from $2.19 trillion during the same period last year, marking the strongest opening half ever recorded despite a slight decline in the total number of transactions.
Rather than a broad-based surge in acquisitions, the record reflected the growing dominance of massive corporate combinations. Total deal count slipped to 21,340 from 21,978 a year earlier, underscoring that fewer—but significantly larger—transactions fueled the market’s expansion.
“The quest for scale has pushed M&A into gigadeal territory,” said Lucinda Guthrie, head of Mergermarket.
The first half produced 48 megadeals valued at more than $10 billion, another record. Together those transactions were worth $1.32 trillion, accounting for 42 percent of all announced global M&A activity. Six transactions exceeded $50 billion, prompting Mergermarket to describe the current environment as the beginning of a new “gigadeal” era. Those six transactions alone represented 16 percent of all global deal value.
Momentum accelerated throughout the spring. Three of the five largest acquisitions were announced in May, helping the month set its own record with $664 billion in announced transactions.
Technology remained the dominant sector for the tenth consecutive quarter, with deal value soaring 76 percent from a year earlier. The surge was led by OpenAI’s $122 billion funding round, one of the largest capital raises ever completed by a private technology company.
Artificial intelligence also reshaped activity in other industries. Utilities and energy reached a record $328 billion across 177 transactions as companies moved aggressively to secure electricity generation, transmission assets, and data-center infrastructure needed to support expanding AI operations.
Among the headline transactions were McCormick’s $42.7 billion acquisition of Unilever’s foods business and SpaceX’s $60 billion agreement to acquire AI coding startup Cursor, highlighting the continuing convergence of consumer products, infrastructure, and artificial intelligence.
Corporate buyers—not private equity firms—continued to dominate the market.
Strategic acquirers accounted for 76 percent of global M&A activity, while financial sponsors remained constrained by elevated borrowing costs and a difficult fundraising environment. Mergermarket reported private equity investment declined 6 percent to $333.2 billion from $354.5 billion a year earlier, although sponsor exits increased 7 percent to $386.7 billion as firms returned capital to investors.
Ivan Farman, co-head of global mergers and acquisitions at Bank of America, said the growing preference for very large deals reflects a practical reality inside corporate boardrooms.
Companies increasingly believe that completing a mid-sized acquisition often requires nearly as much executive time, legal work, financing, and regulatory effort as completing a much larger transaction, making transformational acquisitions more attractive when the right opportunity becomes available.
The strength was not evenly distributed across every segment of the market.
Mitch Berlin, vice chair of EY Americas, recently said chief executives continue viewing acquisitions as one of the fastest ways to reposition businesses around artificial intelligence despite ongoing trade uncertainty. He expects strategic deal activity to remain strong while private equity continues taking a more cautious approach.
That caution was evident in the middle market. Transactions valued between $250 million and $1 billion increased 16 percent year over year to $404 billion, but activity slowed compared with the second half of 2025.
North America remained the center of global dealmaking, generating $1.78 trillion, or 56 percent of worldwide transaction value, representing a 66 percent increase and the strongest first half ever recorded for the region.
Europe, the Middle East and Africa posted an even larger percentage increase, climbing 87 percent to $847.5 billion, the best opening half since 2007.
Asia-Pacific moved in the opposite direction, with activity falling 24 percent to $474.1 billion as weaker Chinese dealmaking weighed on the region.
The surge also produced another busy period for Wall Street’s advisory firms. Goldman Sachs, JPMorgan, and Morgan Stanley topped the global league tables, with each advising on more than $500 billion worth of announced transactions during the first half.
With the report covering activity through July 1, the second half of 2026 will determine whether corporations can maintain the pace. For now, the message from boardrooms is clear: companies continue betting that greater scale, stronger balance sheets, and artificial intelligence-driven growth outweigh economic uncertainty, keeping the global merger boom firmly intact.
