Key data from Mergermarket reveals that the total value of global mergers and acquisitions in the first half of the year surged by 44% in US dollar terms, setting a new record for the period.
The surge in global M&A value has been propelled by several high-value artificial intelligence transactions and a concentrated rush by US companies to finalize deals.
Overview
The total value of global M&A deals in the first half of the year rose 44% year-on-year, surpassing $3 trillion and setting a new first-half record.
Mergermarket data shows that despite a slight decline in the total number of deals, major AI-related acquisitions and a wave of US companies rushing to complete transactions have collectively driven the global M&A total beyond $3 trillion for the first half.
Measured in US dollars, the scale of M&A activity from January to June increased by 44% compared to the same period last year, marking the highest first-half figure on record. Investment banks facilitating these deals have largely disregarded the impact of Middle East conflicts on energy prices and financing costs.
Lucinda Guthrie, Executive Editor at Mergermarket, commented: "In past years, a single event would have been enough to be considered a black swan, yet this year, despite a succession of various risk events, the market has remained unaffected and continued to push deals forward."
This wave of M&A activity has been driven by mega-deals valued over $10 billion, which collectively accounted for 42% of the total deal value. The report also notes that this year saw a record number of six deals exceeding $50 billion in value.
Large-scale mergers have predominantly centered on the artificial intelligence sector, with OpenAI's $122 billion financing round in February and NextEra Energy's proposed $67 billion acquisition of Dominion Energy being the most notable. The report points out that the AI boom has led to a surge in electricity demand for computing power, granting the energy sector M&A benefits comparable to those in the software industry.
The report states that the high deal values mask a polarized market landscape: the overall number of M&A transactions in the first half declined by 3%.
The current market is dominated by large corporations, which possess robust balance sheets enabling them to pursue significant acquisitions. Small and medium-sized enterprises, however, are struggling, with their management being more sensitive to macroeconomic volatility, high interest rates, and geopolitical risks.
Mergermarket suggests that the demand for AI-related M&A in the second half of the year remains uncertain. If interest rates remain high or increase further, the pace of M&A activity could cool. Guthrie added that there is growing market skepticism about whether technology companies can bear the high costs of AI infrastructure and translate them into substantial profits.
"Once a valuation correction occurs in the AI sector, the sustainability of the mega-deal wave will be called into question."
In the short term, a unique window exists in the US market: dealmakers are hurrying to utilize the current permissive regulatory environment for mergers. M&A deal value in the US soared by 72% in the first half. This momentum is expected to continue for the next six months, as large companies aim to complete transactions before the potential end of the Trump administration and a possible shift in regulatory stance.
Guthrie stated: "There is a widespread belief in the industry that if these transformative, industry-altering mergers do not happen now under the current administration, there may be little opportunity to execute them under a future government."
