Global M&A hits $2.8 trillion in H1 2026, with mega-deals and AI infrastructure driving a concentrated surge

Global M&A announced value hit $2.8 trillion in the first half of 2026, up 48% year-on-year and the highest first-half total since LSEG records began in 1980, according to Reuters, citing LSEG data. Yet the number of individual deals fell 9% to roughly 24,000, a six-year low. The headline is clear: fewer, bigger transactions are doing almost all the work.

Forty-seven deals above $10 billion, totaling more than $1.3 trillion, accounted for nearly half of global deal volume, an all-time record for mega-deal concentration, per Reuters. Marquee transactions included NextEra Energy's $66.8 billion merger with Dominion Energy and SpaceX's roughly $60 billion acquisition of Cursor. For enterprise operators, the practical implication is not the deal ticker. It is what that concentration signals about where capital is flowing and how quickly the supplier and partner landscape can be reshuffled beneath them.

Industrial manufacturing leads the charge

Within the broader surge, industrial manufacturing is punching above its weight. PwC's 2026 midyear outlook, published in June, found that M&A activity in the sector climbed to $173 billion over the past year, a 28% increase over fiscal year 2025's $135 billion. Transactions above $5 billion now make up 56% of industrial manufacturing deal value, up sharply from 18% in fiscal year 2024, according to the report as covered by Manufacturing.net.

Even excluding those blockbusters, average transaction size in industrial manufacturing grew 31% from fiscal year 2024 to $169 million. PwC's data, as reported by Manufacturing.net, traces a steady climb: average deal values were $155 million in fiscal year 2024, $288 million in fiscal year 2025, and $375 million in the most recent annual period. That 139% rise over two years points to buyers paying for transformative capability, not just incremental scale.

Strategic acquirers, not private equity, are driving the bulk of this activity. According to PwC's findings as reported by Manufacturing.net, strategic buyers account for 86% of the last 12 months' industrial manufacturing deal value and 86% of year-to-date 2026 volume. Private equity remains active in the upper mid-market but is not setting the agenda at the top of the deal size range.

AI and convergence are reshaping which assets get acquired

The deal rationale is shifting. Boston Consulting Group's mid-2026 M&A analysis, authored by Jens Kengelbach, Daniel Friedman, and Dominik Degen, reports that AI is reshaping competitive dynamics faster than most companies can build capabilities organically, increasing the urgency of acquisition over internal development. BCG notes that global deal value in H1 2026 rose approximately 28% compared to the same period in 2025, reaching roughly $1.6 trillion in completed and announced transactions tracked by BCG, with 31 megadeals above $10 billion in H1 alone, up from 17 in the same period a year earlier.

BCG also identifies a sharp internal divide in the technology sector: AI infrastructure-layer assets, covering power infrastructure, frontier models, and data center components, continue to command strong valuations, while traditional software companies face mounting structural pressure. That divergence matters for operators evaluating technology partners or renegotiating platform contracts: the vendor landscape is bifurcating, and consolidation will accelerate on both ends.

PwC's analysis, reported by Manufacturing.net, makes the convergence case numerically: from 2021 to 2025, industrial manufacturing accounted for 155 convergence deals and $532 billion in transaction value, more than any other industrial subsector. Power equipment, thermal management, automation and controls, and advanced components are attracting premiums of 15% to 30% above sector medians, peaking in AI compute and data center-exposed assets. Buyers, PwC notes, are increasingly requiring evidence of AI impact directly in the income statement, through throughput improvements, labor cost offsets, and predictive maintenance savings, before paying those premiums.

Divestitures are generating a new supply of strategic assets

On the sell side, corporate simplification is creating opportunities at scale. Honeywell's three-way separation is the most cited example, with PwC's report, as covered by Manufacturing.net, describing it as emblematic of a broader conglomerate breakup trend that is releasing carve-outs across automotive-exposed, advanced materials, and non-core industrial assets. Among industrial companies executing acquisitions above $5 billion since 2021, nearly 69% have also divested, and that figure rises above 86% for serial acquirers.

Reuters noted a record level of corporate separation activity in H1 2026, citing Comcast's planned spinoff of NBCUniversal and Sky as one high-profile example. Bankers told Reuters that companies are adapting to shifting industry dynamics and using divestitures to fund focus. For procurement and supply chain leaders, that means established supplier relationships can change ownership with limited notice, and long-term contracts may be renegotiated as new strategic owners set priorities.

Cross-border activity adds another layer of complexity. PwC found that cross-border deal value has reached 56% of the last 12 months' industrial manufacturing total, up from 30% in fiscal year 2022, with U.S.-targeted deal value nearly doubling in fiscal year 2025 to $72 billion. Global supply chain reconfiguration and reshoring investments are the primary drivers, according to the report.

What operations and procurement teams should be tracking

BCG's mid-2026 analysis cautions that while strategic logic for M&A has strengthened, the window to acquire assets at reasonable valuations may already have closed in some sectors. The firm notes that BCG's M&A Sentiment Index currently stands at 84, below its long-term average of 100, suggesting deal practitioners remain cautious even as headline numbers climb. Volume for smaller deals is still subdued, and activity is concentrated in a limited number of sectors and regions rather than distributed broadly.

For the operator managing vendor relationships, supplier contracts, or technology platform decisions, the near-term signal is consistent across all three analyses: the industrial asset base is being actively reorganized. Companies that map their key dependencies against active divestiture pipelines, and that stress-test capability density rather than single-theme exposure in supplier evaluation, will be better positioned as ownership of critical components and services continues to shift.

Reuters reported that Morgan Stanley's Jan Weber described a growing pipeline of cross-border, strategic deals building momentum behind the scenes over recent weeks. Whether or not the market eclipses the 2021 post-pandemic peak, the structural forces, AI infrastructure demands, grid buildout, defense spending, and portfolio simplification, are not cyclical. They are the new operating context.
