Global mergers and acquisitions demonstrated strong performance in the first eight months of 2026, with aggregate deal value rising 15% year over year to $2.09 trillion, according to Boston Consulting Group (BCG). The gains were primarily concentrated at the upper end of the market, as transactions worth $10 billion or more climbed to 37 deals, up from 24 a year earlier, surpassing the 32 megadeals announced in the same period of 2021. However, total deal value has not fully recovered, remaining 28% lower than the $2.91 trillion recorded in 2021 despite the higher megadeal count. US deal value rose 25% in the first seven months of 2026 compared with the same period last year, outpacing the global increase of 19%, but deal volume fell 26% - a steeper decline than the 16% drop globally. This concentration pattern mirrors projections from consulting firm PwC, which in June predicted global M&A deal value would approach $4 trillion this year while deal counts fell 13%.
The M&A recovery shows clear segmentation, with deals between $250 million and $1 billion staying below average levels, as reported by BCG. Transactions under $250 million also failed to reach normal volumes when excluding inflation effects. Deal volumes in these segments remain below their longer-term averages, indicating that the global M&A market has not yet regained normal levels of breadth, according to the consulting firm's analysis. Transaction activity across the broader market dropped to its lowest level since the pandemic-disrupted first half of 2020, with BCG noting that transactions valued below $1 billion remain below longer-term norms even before adjusting for inflation. This concentration pattern mirrors projections from consulting firm PwC, which in June predicted global M&A deal value would approach $4 trillion this year while deal counts fell 13%.
Regional distribution showed significant variation, with North America accounting for more than half of aggregate deal value, while European value rose 43% to $541 billion and Asia-Pacific activity fell 27%, according to BCG data. Sector performance diverged sharply, with financial institutions and real estate scoring 108, health care reaching 100, technology coming in lowest at 52, and consumer at 64 on BCG's M&A Sentiment Index. European dealmaker sentiment, at 100 on the M&A Sentiment Index, is running well ahead of the Americas' reading of 73, suggesting US financial services dealmakers are more cautious about near-term conditions than their counterparts across the Atlantic. UK financial institutions and real estate deal value reached $67.4 billion - more than double the $31.5 billion recorded over the same period in 2025, with the Nuveen's proposed $12.9 billion acquisition of Schroders standing as the largest wealth management deal announced through July. European banking consolidation remained active, with UniCredit's ongoing pursuit of Germany's Commerzbank and Italy's Unipol Assicurazioni agreeing to acquire selected assets of Banca Monte dei Paschi di Siena for up to $4.0 billion.
Artificial intelligence is creating mixed effects on the M&A landscape, as noted by BCG's global leader of transactions and integrations Daniel Friedman. AI works on the market in two directions at once: it's a reason to do more deals and a reason some deals are harder to close, with companies that work out which effect applies to specific assets likely to gain competitive advantage. BCG cites a software valuation correction and private equity pullback as evidence of the second effect, while the firm's M&A Sentiment Index, which blends market fundamentals with AI-based analysis of corporate communications, rose to 83 from 79 at the start of the year. BCG frames deal executability around five tests: asset readiness, market-clearing economics, resilient financing, organizational capacity, and regulatory clearance, with asset availability and economics currently the most binding constraints on a broader recovery.
BCG global M&A leader Jens Kengelbach identified execution constraints rather than funding availability as the current market bottleneck. Capital and strategic appetite are available. The bottleneck has shifted to execution: finding transaction-ready assets, bridging valuation gaps, and clearing the operational and regulatory hurdles required to close, he explained. The crypto M&A sector has followed similar patterns, with disclosed crypto M&A deal value setting a record $9.66 billion in the first half of 2026, even as announced deals fell 25% to 87, demonstrating the ongoing concentration trend across different market segments. BCG also points to portfolio rotation as a potential catalyst for the next leg of activity, noting that a greater number of divestitures, carve-outs, and private equity exits could increase the supply of prepared assets and free up capital for higher-priority businesses.
