Mega deals are back and driving M&A to a five year high

Global M&A value has surged to a five-year high of $438 billion in the first quarter of 2026. Driven by a historic return of $10 billion "mega-deals," corporate boardrooms are finally shaking off geopolitical noise to prioritize strategic scale and AI integration.

If the last few years of M&A felt like a long, cautious winter, the first quarter of 2026 just delivered a sudden, loud spring.

We’ve all been watching the same headwinds: high volatility, geopolitical tension, and a general sense of “wait and see.” But according to the latest data from WTW’s Quarterly Deal Performance Monitor (QDPM), the “wait” is officially over. Global deal value didn’t just tick upward; it skyrocketed to a five-year high of $438 billion.

For those of us in the C-suite, the most telling metric isn’t the total dollar amount, it’s the return of the “mega-deal.”

The $10 Billion Comeback

In the first three months of this year, 12 deals valued at over $10 billion crossed the finish line. To put that in perspective, we haven’t seen a quarter that active for mega-deals since before the 2008 financial crisis. Compare that to the mere two mega-deals we saw in the previous quarter, and the shift in sentiment becomes clear: the “animal spirits” have reawakened.

Jana Mercereau, WTW’s Head of Europe M&A Consulting, puts it bluntly: “Mega transactions have re-emerged with a vengeance”. Companies aren’t just sitting on their cash anymore; they are moving aggressively to bridge capability gaps and secure the AI infrastructure they need to survive the next decade.

A Market That Finally Rewards Risk

Perhaps the most encouraging news for CFOs is that the market is finally nodding in approval.

Late last year, companies engaging in M&A were getting hammered, underperforming the MSCI World Index by nearly 14 points. This quarter, that flipped. Acquirers actually outclassed the wider market by +2.5pp.

The Bottom Line: Strategic Scaling vs. Geopolitical Noise

So, what’s actually changed? It’s not that the world got safer. Mercereau points out that the ongoing conflict in the Middle East still has the potential to throw a wrench in the works, likely forcing us to “stretch timelines and deepen due diligence”.

The real change is in the boardroom. CFOs and CEOs seem to have normalized the noise. With healthy balance sheets and a more favorable regulatory environment, the focus has shifted from “surviving the volatility” to “strategic scaling”.

Confidence is a fragile thing in finance, but for the first time in five years, the data suggests that dealmakers are no longer afraid of the dark. They’re resolved to ride through the bumps and persist with the deals that will define their future.
