Global M&A is rising in 2026, but don’t think of it as a repeat of the 2021 frenzy.
Early data shows deal value climbing sharply while deal count remains under pressure. The market is moving, but not evenly, and for corp dev teams, that distinction matters more than the headline number.
Is M&A activity rising in 2026?
Yes. Q1 2026 global M&A exceeded $1.2 trillion, up 26% year over year, even as the number of deals fell 17%, according to LSEG data reported by Reuters. That split reveals something critical: successful deals are bigger and more strategic, not more frequent.
This follows a record-setting 2025, when total deal value surged nearly 40% to $4.9 trillion, surpassing the previous high set in 2021, according to PitchBook data cited by CNBC. The rebound many dealmakers expected in 2023 and 2024 finally arrived, and it arrived with scale.
But BCG's M&A Sentiment Index, while improved, remains below long-term historical averages. Confidence is returning, but has not fully recovered. That tension is shaping how boards and corp dev teams are approaching the current cycle.
Why M&A is rising again
Five structural forces are driving the current wave of deal activity, and we’ll explore them in detail below. Understanding these structural forces can help corporate development teams anticipate where competition for assets will intensify, refine their acquisition strategy, and position themselves ahead of shifting market dynamics.
AI and technology are forcing capability-driven acquisitions
AI is a forcing function for acquisitions across industries. Companies that can’t build AI capabilities fast enough? Well, they’re buying them. Four of the six largest deals in Q1 2026 involved companies that investors consider positioned to win the AI race, according to Reuters and LSEG.
This is accelerating deals in software, data infrastructure, cybersecurity, semiconductors, and cloud-adjacent services. It’s also creating a new category of target: the AI-vulnerable company. Here, investors are watching valuations fall before acquirers move. Corporate development teams that understand the AI threat to their own sector are moving first. The ones waiting for clarity are moving second.
Large companies are reshaping portfolios
The post-pandemic era produced a wave of diversification deals that many companies are only now unwinding. Strategics are divesting non-core businesses and using the proceeds to double down on areas of competitive strength. That creates sellers and buyers simultaneously, and it means the M&A process involves just as much disciplined divestiture thinking as it does acquisition strategy.
For corporate development teams, this reinforces the importance of a clear deal thesis before entering any process. When the market is full of assets coming available for strategic reasons, the teams with the tightest criteria close the right deals. The teams without criteria? They close the easy deals.
Private equity needs liquidity and new deployment
PE firms entered 2026 with a significant backlog of portfolio companies needing exits and capital that needed to be deployed. The combination of improving valuations, lower interest rates (following a Fed cut in December 2025), and a more permissive regulatory environment created the right conditions for a deployment and liquidity cycle to run simultaneously.
That means corporates are competing with well-capitalized financial buyers more often than they were in 2023 or 2024. And remember: speed of process and certainty of close matter more when PE is in the room.
Cross-border activity is hitting record levels
Cross-border M&A rose 47% year over year to a record $454.7 billion in Q1 2026, according to LSEG. European companies facing slowing domestic growth are moving into the U.S. market, and U.S. companies are pursuing global consolidation in sectors where scale matters.
For corporate development teams, this raises diligence complexity. Cross-border deals introduce regulatory, cultural, and operational integration variables that purely domestic transactions don’t. For this reason, the teams that handle them best are those that have built repeatable diligence systems that account for jurisdictional variance.
Megadeals are carrying the market
Deal count is down 17%, but deal value is up 26%. That math only works if the deals getting done are substantially larger than average, and they are. Megadeals ( transactions valued above $5 billion) accounted for more than 73% of the increase in deal value in 2025, according to Bain & Company.
This concentration has implications for how mid-market corporate development teams perceive the market. The headline numbers suggest a hot market, but the deal count numbers tell a very different story: competition for quality assets is intense, processes are rigorous, and the margin for error in diligence and deal thesis validation is smaller.
Why 2026 is different from the 2021 boom
The 2021 M&A boom was driven by cheap capital, optimism about pandemic recovery, compressed timelines, and high asset valuations that many acquirers paid for without adequate scrutiny. SPAC activity was at a peak, and speed was a competitive advantage, sometimes at the expense of diligence quality.
2026 is being shaped by different forces:
- Strategic urgency — AI disruption and portfolio rationalization are creating genuine business pressure to act, not just financial opportunity
- Selective capital — The proportion of capital allocated to M&A hit a 30-year low in 2025, according to Bain, as companies prioritized buybacks, dividends, and capex. The capital going into M&A now is more considered
- Regulatory complexity — Cross-border deals and AI-related acquisitions face heightened scrutiny in multiple jurisdictions
- PE discipline — PE buyers in 2026 are more selective than in 2021, prioritizing quality over volume
- Integration accountability — Boards and investors are asking harder questions about integration track records before approving deals
The acquirers that struggled through the 2021-2023 period of overpriced deals, integration failures, and unrealized value are informing how boards think about the current cycle. The market is more active, but also more skeptical of deals lacking a rigorous operating rationale.
What this market means for corporate development teams
A rising M&A market does not automatically mean easier deals. And for corporate development teams, it can actually mean the opposite.
More deals being done in parallel means more competition for high-quality assets, faster processes, and less tolerance among sellers for unprepared buyers. When deal activity concentrates in megadeals and strategic transactions, the pressure on each deal to be right increases.
Several patterns show up consistently when M&A markets get more active:
- Teams that lack a shared M&A operating language slow down at exactly the wrong moments. A deal moving at the pace of a competitive process leaves little room for internal disagreement over what diligence should cover or how integration should begin. The teams that move fast and stay disciplined have done the alignment work before live deal pressure hits.
- Diligence quality suffers when teams run multiple processes simultaneously. Without standardized diligence questions by deal type, corporate development teams either over-invest in diligence cycles that do not result in closes or under-invest in deals that do close, only to surface problems post-LOI.
- Integration planning that starts at LOI outperforms that which starts at close. A rising deal market exposes teams that treat integration as a post-close activity. The window between LOI and close is where the integration thesis either gets built properly or gets improvised. The improvised versions cost more and take longer.
How buyers should prepare for the 2026 deal cycle
The teams that will perform well in the current cycle are the ones building their operating capability now, before the next deal appears. That means:
Build a deal thesis framework before diligence expands.
Every deal should have a thesis that can survive challenges. What is the strategic rationale? What is the value capture plan? What integration assumptions is the thesis dependent on? Answering these before diligence expands prevents teams from continuing down the wrong path because of sunk costs.
Standardize diligence questions by deal type.
Not every deal requires the same depth in every workstream. Teams that have built diligence frameworks by deal type (capability acquisition, market entry, platform build, bolt-on) move faster and miss fewer critical issues.
Create decision checkpoints before IOI and LOI.
The most expensive place to change your mind is after LOI. The decision framework should have clear go/no-go criteria at each gate: initial screen, IOI, management presentation, LOI, and confirmatory diligence.
Train newer team members before live deal pressure hits.
Corporate development teams typically learn M&A by doing it. That works when deal volume is low and timelines are loose. In a more active cycle, newer team members without a foundational operating framework slow the team down at critical moments.
Build integration playbooks from real deals, not theory.
Generic integration checklists create false confidence. The teams that integrate well have built playbooks from their own deal history — what went wrong, what they would do differently, what the integration kickoff should cover.

Frequently asked questions about M&A activity in 2026
Is M&A activity increasing in 2026? Yes. Global M&A exceeded $1.2 trillion in Q1 2026, up 26% year over year, according to LSEG data. Deal value is rising significantly even as the total number of transactions has declined, indicating a more concentrated, strategic market.
Why is M&A activity rising again? Several forces are converging: AI is driving capability-driven acquisitions across industries; large companies are rationalizing portfolios; private equity is deploying capital after a slow 2023 and 2024; cross-border activity is at record levels; and improved financing conditions are supporting large-scale transactions.
How is 2026 different from the 2021 M&A boom? The 2021 boom was fueled by cheap capital, pandemic-recovery optimism, and inflated valuations, all of which led to overpriced deals and integration problems at many companies. The 2026 cycle is being driven by strategic urgency, AI disruption, portfolio simplification, and more selective capital deployment. Boards are applying more scrutiny before approving deals.
What industries are driving M&A in 2026? Technology, financial services, healthcare, and energy are leading deal activity, according to BCG. AI-adjacent sectors (data infrastructure, cybersecurity, semiconductors, software) are particularly active. Cross-border deals and media consolidation are also prominent features of the current cycle.
Why are deal values rising while deal count is falling? The deals getting done are larger and more strategic. Megadeals above $5 billion accounted for more than 73% of the increase in deal value in 2025. Boards and corporate development teams are being more selective about which processes to enter, but when they do move, it is for significant transactions.
How should corporate development teams prepare for more M&A activity? Teams that perform well in active markets have done the foundational work before deal pressure hits: a clear deal thesis framework, standardized diligence by deal type, decision checkpoints before LOI, and integration playbooks built from real deal experience. Teams that lack these systems slow down when deals move fast.
