AI investments and an explosion of megadeals are creating a K-shaped M&A market

Diegem, 29 January 2026 - Momentum heading into 2026 suggests that global M&A is entering a new phase, shaped less by cyclical recovery and more by structural change. In its latest Global M&A Industry Trends - Outlook 2026, PwC reports a resurgence of megadeals, combined with accelerating investment in AI and enabling infrastructure, driving higher deal values even as volumes remain muted. “This divergence highlights the emergence of a K-shaped M&A market, where activity is increasingly concentrated among large, well-capitalised buyers and select markets and sectors,” says Veronique Gilles, Partner PwC Belgium.
The semi-annual publication PwC’s Global M&A industry trends gives some clear insights on how the multitrillion-dollar AI capital expenditure supercycle is reshaping capital allocation decisions. In the near term, this wave of investment may divert funding away from some acquisitions. Over the medium term, however, PwC reports AI’s potential to drive productivity and innovation is expected to reignite dealmaking, as companies use M&A to accelerate transformation, acquire capabilities and reposition portfolios, according to PwC. For dealmakers, the implication is clear: M&A is reopening, but unevenly. Success in 2026 will depend on conviction, capital access and strategic clarity rather than waiting for perfect conditions.
Megadeals are driving value in a polarised market
Global M&A values rose 36% in 2025, driven by a sharp increase in megadeals. PwC is seeing the same trend in Belgium: Belgian M&A values rose approximately 90% in 2025, after a fallback in 2024, driven by a few megadeals. Global and local deal values are being lifted by a relatively small number of large transactions, while mid-market activity remains constrained by valuation gaps, execution risk and uncertainty—reinforcing a K-shaped M&A recovery.
Veronique Gillis, Partner and Deals Leader, PwC Belgium says:
“As we head into 2026, the resurgence of megadeals is signalling a renewed sense of confidence across global M&A. With valuation gaps narrowing, capital re‑engaging and rates trending positively, momentum should continue to build. Decisive dealmakers, rather than those waiting for ideal conditions, will be best placed to capture opportunities.”
