In the fiercely competitive world of American Biglaw, size is a badge of honor, and the 2026 National Law Journal's (NLJ) annual ranking, the NLJ 500, has just confirmed which firms are wielding the most clout. This year, Dentons continues to lead the pack, retaining its title as the largest law firm in the U.S. by headcount, a noteworthy achievement in an industry that measures success by every conceivable metric.

For those fascinated by the legal profession's titans, the NLJ 500 ranking provides a detailed look at firm sizes, shedding light on the giants of the legal field. This year’s top ten is a veritable who's who of the legal industry, featuring names like DLA Piper, Baker McKenzie, Kirkland & Ellis, and Latham & Watkins, among others. These firms are not only massive in scale but also reflect the dynamic shifts within the legal marketplace.

Despite economic and political pressures that have generally slowed growth across the sector, the NLJ report indicates an average increase in firm size, with headcounts growing by 2.5% from the previous year. This growth, however, comes with a shift in the structure of partnerships. While the number of nonequity partners has seen a rise of 5% in 2025, continuing a trend from 2024, equity partners have slightly declined by 0.2%.

This structural shift highlights an ongoing transformation in Biglaw, where the balance between equity and nonequity partners continues to adjust in response to broader market conditions. The growing number of nonequity partners suggests that firms might be preserving capital or managing risks more conservatively by offering fewer equity positions, which typically promise higher earnings and a share in decision-making.

The detailed rankings and insights from the NLJ 500 are not just numbers but paint a picture of an evolving industry where size and structure are closely managed to adapt to external pressures and internal strategies. The full list available on the NLJ website offers an in-depth look at how these firms stack up in their quest for growth and operational efficiency.

Congratulations are in order for Dentons and all the top 10 firms who continue to set benchmarks in the legal industry. Their ability to maintain and grow in a challenging environment is a testament to their strategic acumen and the hard-working professionals who make up their rosters. For the rest, the challenge remains: grow and adapt to join the ranks of these behemoths.
