Summarized by Rubicon Research · 3 min read

Bain & Company's 2026 midyear M&A report describes a global deal market running near record pace, led by very large transactions.

Key figures

  • Global M&A rose 41% year over year to $2.4 trillion in the first five months of 2026.
  • Bain projects full-year deal value above $5.3 trillion, close to the 2020 record of $5.6 trillion.
  • Deals worth more than $10 billion grew 52% in number and 53% in value.
  • Deal value from financial sponsors fell 9% through May, while venture capital deal value rose 206%.

The "winner's paradox"

Bain argues that acquirers now have to pursue an ambitious M&A agenda and an AI transformation at the same time, and that AI's effect on deals reaches well beyond the technology sector. Waiting on either, the report says, is not a practical option.

Rubicon's take

Bigger deals and faster timelines raise the stakes on what diligence misses. Bain's own earlier research found that poor diligence is the most common root cause of deal failure. Read our summary.
