For years, a $1 billion transaction was one of the clearest signals of a major M&A market. It represented scale, confidence, and access to significant capital. Today, however, the more interesting story is what is happening around that threshold: buyers are doing fewer deals, but putting more capital behind the ones they truly believe in.
Global M&A value is expected to approach $4 trillion in 2026, even as transaction volumes decline. At the same time, deals above $5 billion are accounting for a much larger share of overall deal value than they did just a few years ago. The market is not necessarily getting quieter; capital is becoming more concentrated.
That concentration reflects a more selective approach to dealmaking. Buyers are looking for businesses that can make a meaningful difference to their long-term strategy, whether that means entering a new market, strengthening a supply chain, adding critical technology, increasing recurring revenues or creating meaningful operating synergies.
For buyers, the question is increasingly not simply whether they can afford a transaction, but whether the opportunity is compelling enough to justify the capital required.
This shift is putting particular pressure on the middle market. Higher financing costs and continued valuation gaps are making some $100 million to $1 billion transactions harder to execute. Buyers are taking longer to commit, while sellers are increasingly having to reconsider their expectations around price and timing.
Yet a more selective market does not mean good businesses are being overlooked. In some cases, the opposite is true.
Companies with strong cash generation, resilient margins and clear strategic value can still attract significant interest. With buyers pursuing fewer opportunities, competition can become even stronger for the assets that genuinely stand out.
Strategic buyers may have an additional advantage. They can sometimes justify paying more than a financial buyer because they can capture synergies, expand distribution or gain access to new customers and markets. Those benefits may not be visible in the target’s standalone financials, but they can materially change the economics of a transaction for the right buyer.
For dealmakers, this changes how the M&A market needs to be read. Total deal value may tell one story, while transaction volumes tell another. The more useful question is increasingly where capital is concentrating, and what is giving buyers the confidence to deploy it.
The $1 billion deal is not disappearing. But its size alone tells us less than it once did.
In today’s M&A market, the most important number may not be the size of the cheque, but the strength of the reason behind it.
