Mergers and acquisitions (M&As) worldwide - statistics & facts
The global mergers and acquisitions (M&A) market staged a rebound in 2025, with the total value of M&A transactions having reached over four trillion U.S. dollars, making it the highest year on record since the previous peak in 2021. This upturn was fueled by falling interest rates, a more relaxed regulatory environment in the United States, and a wave of mega-deals that reshaped entire industries.
Technology and media lead the deal landscape
The technology, media, and telecommunications (TMT) sector dominated M&A activity in 2025, leading both in the number of deals and in total deal value. More than double the value recorded by the second-ranked sector, industrials and chemicals. Several of reflected the growing appetite for digital infrastructure and media assets, including the 40 billion U.S. dollar acquisition of Aligned Data Centers by a consortium featuring BlackRock, Microsoft, and NVIDIA, as well as Paramount's headline-grabbing takeover of Skydance's Warner Bros. Discovery. Beyond TMT, financial services, energy, and pharma each generated deal values well above half a trillion U.S. dollars, rounding out the most active sectors.
North America drives the mega-deal wave
North America remained the focus point of global dealmaking in 2025. Total M&A transaction value in the region reached roughly 3.2 trillion U.S. dollars. The top ten largest inbound deals in the U.S. accounted for a notable percentage of the regions overall value. Led by Paramount Skydance's acquisition of Warner Bros Discovery, this acquisition alone accounted for almost 82 billion U.S. dollars. Union Pacific's takeover of Norfolk Southern ranked second, generating a deal value of 71.4 billion U.S. dollars. On the advisory side, Goldman Sachs maintained its position as the top financial advisor by value of deals announced.
Regional dynamics and the road ahead
Beyond North America, the Asia-Pacific region saw M&A transaction values climb to nearly two trillion U.S. dollars. Europe saw an increase, up from the previous year, driven by strategic plays in financial services and consumer goods, generating some of the largest European inbound deals. Looking into 2026 and beyond, the M&A market appears increasingly "K-shaped," favoring large, technology-led transactions. With trillions of dollars expected to flow into Artificial Intelligence (AI) infrastructure over the coming years and private equity firms sitting on considerable dry powder, the conditions for continued mega-deal activity remain firmly in place, even as rising geopolitical tensions and regulatory scrutiny add complexity to cross-border transactions.
