Kirkland & Ellis, Latham & Watkins lead M&A adviser rankings in 2026

Summary

Kirkland & Ellis has emerged as the top global M&A legal adviser by deal value in the first nine months of 2026, while Latham & Watkins led in the number of deals advised, according to new data from LSEG. Overall, M&A deals in this period reached $3.9 trillion, a 28% increase from the previous year, marking the strongest start for deal-making since 2021. However, the third quarter revealed significant challenges as aggregate deal value plummeted by 41% compared to the second quarter, falling below $1 trillion for the first time since mid-2025 due to factors such as stock market volatility, rising oil prices, and stubborn inflation. Looking ahead, industry leaders anticipate caution for larger transformational deals but expect ongoing activity in other M&A segments.
