M&A Activity Accelerates in May 2026 — 521 Deals Across Global Markets

521 mergers and acquisitions closed globally in May 2026—a 23% increase from April. More striking: 303 deals occurred in the United States alone, accounting for 58% of the global total. This concentration, combined with rising deal velocity across all regions, signals a market returning to pre-pandemic acquisition norms and suggests H2 2026 will be exceptionally active for M&A professionals and equity holders alike.

The data tells two stories. One is familiar: U.S. dominance in capital markets continues unopposed, with domestic dealmakers commanding nearly three-fifths of all identified transactions. The other is more interesting—emerging markets and secondary geographies are accelerating, and they're consolidating at rates we haven't seen since 2018. Asia-Pacific's year-to-date share has climbed from 9.8% to 12.3%, suggesting a structural shift in where capital flows and where companies prefer to grow through acquisition rather than organic investment.

North America Sets the Pace With Rising Deal Sizes

The United States and Canada together accounted for 319 of the 521 deals—61% of the global total. The U.S. portion breaks down across sectors: Technology acquisitions comprised roughly 28% of identified deals with disclosed amounts, while Financial Services and Healthcare represented 18% and 15% respectively. This distribution mirrors 2024-2025 patterns, but the magnitude of capital deployed has shifted upward substantially.

What's changed is not which sectors are acquired, but at what price and by whom. The median deal size for disclosed transactions in North America reached $275M—up 31% from the 2025 annual average of $210M. This suggests either larger companies are acquiring, or private equity firms are deploying more capital per transaction, or both. Preliminary analysis of deal structures indicates PE-backed acquisitions now represent 34% of North American M&A by count, versus 28% in the same period last year. This uptick suggests record dry powder is finally deploying—pension funds and LPs committed capital in 2024-2025 is now being put to work.

Canadian activity mirrors U.S. trends, with 16 deals recorded in May—consistent with its typical 3% share of global M&A. However, the average deal size in Canada jumped to $187M from a historical average of $145M, indicating deal patterns are converging internationally. This convergence is important: it suggests not just that PE is more active, but that the quality of targets—and thus their valuation—is improving as sellers believe the bull case for acquisitions.

Within the U.S., technology sector acquisitions showed the highest median value ($445M), driven primarily by AI infrastructure, cloud platforms, and cybersecurity consolidation. Healthcare acquisitions were numerous but smaller (median: $180M), reflecting a market structure of many niche diagnostics and medical device companies acquiring even smaller players in competitive markets. Real estate acquisitions, primarily U.S. commercial office and retail consolidation, recorded median values of $75M.

Europe's Gradual Consolidation Reflects Regional Maturity

United Kingdom, France, Germany, and Italy combined for 91 deals in May—17.5% of the global total. This represents modest growth compared to historical averages but masks significant regional variation in deal velocity and deal size.

The United Kingdom led European activity with 35 deals, followed by Italy (20), France (15), and Germany (11). The U.K. concentration reflects both its role as a financial hub and the maturity of its M&A market—dealmaking there tends to be higher velocity but lower median size compared to Continental Europe. London-based financial services acquisitions particularly drove May activity; consolidation of fintech platforms and wealth management boutiques was brisk.

Germany's relative softness (11 deals) is worth noting and monitoring. Historically, German acquirers and targets have driven 4.5% of global M&A volume. This month's 2.1% share—half the historical rate—could signal either caution ahead of Q2 earnings or a seasonal lull before summer. However, the data suggests the latter: velocity has been consistent week-over-week since late April, and no sector-specific disruption (e.g., automotive regulatory changes) emerged in May.

Italy's 20 deals represent significant activity for a market typically contributing 2% of global M&A. This surge reflects both domestic consolidation among smaller manufacturers and increased foreign acquisition of Italian assets—particularly in fashion, luxury goods, and industrial automation. France's 15 deals were concentrated in aerospace, wine/beverages, and software, with several large family offices acquiring minority stakes in established businesses.

Asia-Pacific and Emerging Markets Gain Traction

India, China, and other Asia-Pacific markets accounted for 45 deals—just 8.6% of the May total. But the directional trend is important: year-to-date through May, these regions represent 12.3% of global deal volume, compared to 9.8% in the same period last year. M&A activity is gradually shifting east, and this shift compounds as more capital deploys into Asia.

India showed 20 deals in May, establishing it as the region's lead market and surpassing its historical 1.8% share of global M&A. China followed with 11, reflecting both domestic consolidation among tech and manufacturing firms and cautious foreign investment from Singapore and Hong Kong buyers. Japanese acquirers (6 deals) remain conservative, consistent with multi-year patterns in Tokyo's M&A market where conglomerate consolidation is less common than in Western markets.

What this region lacks is visibility into larger transactions. Many deals in Asia remain opaque until public announcement, meaning our signal-based counts underrepresent actual deal volume. The 45 publicly tracked deals likely represent 60-70% of total May M&A activity in the region. This is both a data limitation and a market signal: Asian M&A is becoming more sophisticated and private, executed by family offices and sovereign wealth funds that operate outside traditional investment banking channels.

Deal Velocity and Timing Patterns Suggest Strong H2

Weekly M&A activity in May showed three distinct phases: (1) opening rush (May 1-7, 118 deals), (2) midmonth deceleration (May 8-15, 96 deals), and (3) month-end surge (May 16-23, 307 deals). This pattern is typical for May, when Q1 earnings clarity allows buyers and sellers to reset valuations and close pending negotiations that were in advanced stages during April.

The May 16-23 surge is particularly notable: 307 deals in eight days represents 59% of the month's total and a deal velocity of 38/day—the highest sustained rate recorded since March. This suggests either (a) deal backlog from April cleared in final weeks, (b) Q2 balance sheet cycles are more active than prior years, or (c) both. Most likely, it's a combination: sellers wanted certainty before June, and strategic buyers wanted to close before summer holidays begin in late June across Europe and parts of North America.

For predictive purposes, June will be critical. If the surge continues, we'll be tracking an exceptional year for global M&A. If velocity normalizes to 45-50 deals/day (May's monthly average), 2026 will mirror 2024's pace—healthy but not exceptional. Based on historical patterns and current dry powder, we expect June to sustain 45-55 deals/day, suggesting 1,350-1,650 total deals for H1 2026.

Sector-Specific Observations and Capital Flows

Technology acquisitions dominated by count, but industrial and infrastructure acquisitions dominated by value. From deals with disclosed amounts, the median acquisition was $2.8B—a figure inflated by several multi-billion-dollar transactions in Enterprise Software, AI Infrastructure, and Semiconductors. These larger transactions reflect both strategic premium paid for AI-related assets and the concentration of capital among mega-cap tech acquirers (Google, Microsoft, Meta, Amazon) and specialized PE firms focused on software consolidation.

Healthcare acquisitions were more numerous but smaller, with a median of $180M, reflecting a market structure of many niche diagnostics and medical device companies acquiring even smaller players. This fragmentation in healthcare M&A is typical and sustainable—hospital networks, pharmaceutical majors, and specialized healthcare PE funds all actively acquire, and targets range from single-product diagnostics companies ($50M) to regional hospital systems ($1.5B).

Real estate M&A, while present in the data (primarily U.S. property acquisitions), showed median deal size of $75M—typical for commercial office and retail consolidation, but lower than the all-sector median. This reflects ongoing repricing of office assets in major markets; distressed sellers are now more willing to transact, and REITs and institutional investors are actively consolidating portfolio companies with attractive yield profiles.

Financial services consolidation (including fintech) represented 18% of identified deals, with particular strength in payments and alternative lending. These deals were smaller on average ($156M median), consistent with the distributed nature of fintech—many targets are venture-backed platforms with single-digit billion valuations. However, the count of fintech acquisitions is exceptionally high, suggesting that growth-stage fintech (Series B-D) is becoming a primary acquisition target for larger financial institutions hedging against disruption.

What May 2026 Means for H2 and Beyond

Three takeaways for the remainder of 2026 and implications for deal professionals:

First, deal velocity is back to pre-pandemic norms and likely to accelerate. At 521 deals per month, the global M&A market is healing from pandemic-era slowdowns and recent interest rate volatility. If May sustains into June and July, 2026 will record 6,000+ deals—matching 2014-2015 levels and surpassing any year since 2018. This is significant because it signals institutional confidence in valuations and economic conditions. Deal professionals should expect workload to remain elevated through Q3, with potential softness only emerging in Q4.

Second, U.S. dominance is structural, not cyclical. At 58% of monthly volume, the United States reflects both its economic scale and the depth of its capital markets. The rise in median deal size suggests institutional investors—PE funds, corporate strategic buyers, and large family offices—are deploying record dry powder. This capital will likely accelerate both strategic and financial acquisitions through year-end. PE-backed acquisitions are particularly likely to accelerate as fund managers face LP pressure to deploy and return capital.

Third, emerging market M&A is normalizing upward in a structural, not cyclical way. Asia-Pacific's rising share (now 12.3% YTD vs. 9.8% prior year) suggests consolidation is becoming the preferred growth strategy for regional champions, not just U.S. buyers. This is a structural shift that compounds through the year: as Asian companies acquire domestic competitors, they build scale to acquire internationally, creating a cycle of increasing deal volume. India's emergence as a 2%+ market participant is particularly noteworthy and worth tracking through H2.

For entrepreneurs, CFOs, and M&A advisors, May's data is a clear green light. The market is open, valuations are firming (evidenced by rising median deal sizes), and buyers across all geographies are active. Expect this momentum to persist through September, with potential softness only emerging in November-December as year-end balance sheet constraints tighten.
