The am law 100 is one of the most recognized rankings in the U.S. legal industry. It identifies 100 major American law firms based primarily on their annual gross revenue. Lawyers, law students, recruiters, businesses, and legal professionals often use the ranking to understand the size and financial strength of leading firms.
The American Lawyer publishes the ranking each year and provides more than a simple list of firms. Its data covers revenue, lawyer productivity, partner profitability, compensation, and headcount. The 2026 ranking reflects financial performance during 2025 and shows another strong year for many large U.S. law firms.
What Is the Am Law 100?
The am law 100 is an annual ranking published by The American Lawyer, which is part of ALM. The ranking focuses on the 100 highest-grossing law firms in the United States and gives readers a useful view of the business side of the legal profession.
Gross revenue determines the main ranking position. However, the report also provides several financial measures that help readers compare firms beyond their total size.
These figures are important because two firms with similar revenue may have very different levels of profitability, lawyer productivity, or partner compensation.
| Metric | What It Shows |
|---|---|
| Gross Revenue | Total annual revenue generated by the firm |
| Revenue Per Lawyer | Revenue compared with lawyer headcount |
| Profits Per Equity Partner | Average profit allocated per equity partner |
| Profits Per Lawyer | Profit compared with lawyer headcount |
| Lawyer Headcount | Average number of lawyers working at the firm |
| Partner Compensation | Financial performance across the partnership |
How the Am Law 100 Ranking Works
The main ranking places firms according to gross revenue. Therefore, a firm with higher annual revenue generally receives a higher overall position than a firm with lower revenue.
The American Lawyer also studies other financial and operational information. These additional measurements allow readers to understand how efficiently a firm converts legal work into revenue and profit.
The am law 100 should therefore not be viewed as a simple measure of legal quality. A high position shows enormous financial scale, but it does not automatically mean that a firm is the best choice for every client or every type of legal matter.
Am Law 100 in 2026
The 2026 edition was published on April 14, 2026, and covers law firms’ 2025 financial results. The latest data showed significant growth across many of America’s largest firms.
According to published ranking data, profits per equity partner across the group increased by about 14% during 2025. Revenue per lawyer also rose by approximately 8.7%, while 92 of the 100 firms recorded an increase in that measurement.
These results suggest that leading firms did more than simply add lawyers. Many firms also improved productivity, pricing power, and profitability during the year.
Why the Am Law 100 Matters
The am law 100 matters because large law firms operate as major businesses as well as professional organizations. They employ thousands of attorneys and handle important corporate transactions, lawsuits, regulatory matters, and international business issues.
Law students may examine the rankings while researching potential employers. Experienced lawyers may use the information when considering lateral career moves. Recruiters can study financial performance when evaluating the strength of different firms.
Companies can also use the information to understand the scale and resources of firms competing for sophisticated legal work.
However, financial rankings should always form only one part of a wider evaluation. Practice strength, client service, geographic coverage, lawyer experience, and industry knowledge can matter just as much.

Gross Revenue and Why It Matters
Gross revenue represents the total revenue a law firm generates before expenses and profit distributions. It remains one of the easiest ways to measure the overall financial scale of a firm.
In the 2026 results, Kirkland & Ellis remained the largest firm by gross revenue, reporting approximately $10.56 billion for 2025. Latham & Watkins followed with approximately $8.30 billion.
Large revenue numbers often reflect a combination of extensive lawyer headcount, premium billing rates, major corporate clients, and strong demand across valuable practice areas.
Still, revenue alone does not reveal how efficiently a firm operates. That is why other measurements remain important.
Understanding Revenue Per Lawyer
Revenue per lawyer, commonly called RPL, measures how much revenue a firm generates relative to its average lawyer headcount.
For example, two firms could each produce billions of dollars in annual revenue. If one firm uses far fewer lawyers to produce its revenue, it may report significantly higher RPL.
This metric can provide useful information about productivity, billing rates, workload, and the type of matters handled by the firm.
The 2026 am law 100 results showed broad improvement in this area. With 92 firms reporting RPL growth, the numbers indicate that higher productivity contributed to the strong financial year.

Profits Per Equity Partner Explained
Profits per equity partner, usually shortened to PEP or PPEP, receives considerable attention whenever the rankings appear.
PEP generally represents the firm’s net income attributable to equity partners divided by its number of equity partners. It provides a useful way to compare partnership economics among firms.
However, PEP does not mean that every equity partner receives exactly that amount. Individual compensation can vary because firms use different compensation systems, ownership structures, performance standards, and profit-sharing arrangements.
The average PEP across the 100 firms reached approximately $3.59 million for 2025, according to published summaries of the 2026 rankings.
Most Profitable Firms by PEP
Several elite firms recorded exceptionally high profits per equity partner in the latest results.
| Firm | Approx. 2025 PEP |
|---|---|
| Wachtell, Lipton, Rosen & Katz | $12.15 million |
| Kirkland & Ellis | $11.12 million |
| Davis Polk & Wardwell | $9.80 million |
| Quinn Emanuel | $9.55 million |
| Gibson Dunn | $8.89 million |
| Latham & Watkins | $8.65 million |
| Paul, Weiss | $8.63 million |
| Simpson Thacher | $8.57 million |
| Paul Hastings | $8.33 million |
| Milbank | $7.62 million |
These numbers show why revenue ranking and profitability ranking can produce very different results. A smaller firm can generate less total revenue but still produce exceptional profits for its equity partners.
Am Law 100 vs. Am Law 200
People sometimes confuse the am law 100 with the Am Law 200. The difference mainly involves the number and revenue ranking of firms included.
The first group covers the 100 highest-grossing U.S. law firms. The Am Law 200 extends the coverage to include firms ranked through 200, with firms ranked 101 through 200 often described as the “Second Hundred.”
This distinction allows legal professionals to compare the largest firms with other substantial national and regional practices.
The Second Hundred remains financially important, but its average revenue and profitability figures are generally below those of the first 100 firms.
What Makes a Law Firm Financially Successful?
Size alone does not guarantee strong financial performance. A large firm can generate enormous revenue while carrying equally large operating expenses.
Highly profitable firms often combine premium legal work with strong demand and disciplined management. They may concentrate on areas such as private equity, mergers and acquisitions, litigation, restructuring, finance, intellectual property, or complex regulatory matters.
Billing rates, client relationships, lawyer productivity, staffing structures, office expenses, and technology can all affect profitability.
A firm that manages these areas efficiently may achieve strong profits without having the largest lawyer headcount.
The Role of Technology and Artificial Intelligence
Technology continues to change the business model of major law firms. Generative artificial intelligence has become an especially important topic because firms are exploring ways to improve research, document review, drafting, knowledge management, and administrative work.
The 2026 ranking analysis highlighted continued interest in AI-driven changes across Big Law. Firms now face the challenge of using technology to increase efficiency while maintaining accuracy, confidentiality, and professional responsibility.
AI may also influence traditional measurements such as revenue per lawyer. If technology allows lawyers to complete some tasks faster, firms may reconsider staffing structures, pricing models, and the way they measure productivity.
Why Law Students Pay Attention to the Rankings
Law students often research large firms before applying for internships, summer associate programs, and permanent positions.
The rankings can help students identify financially strong employers and understand the competitive Big Law market. However, students should not select an employer based only on revenue or PEP.
Office location, practice area, training, work culture, promotion opportunities, working hours, and long-term career goals deserve equal attention.
A lower-ranked firm may provide a much better career opportunity for a particular lawyer if it specializes in that person’s preferred field.
Limitations of the Rankings
Financial rankings provide valuable information, but they cannot measure every feature of a law firm.
For example, a revenue ranking does not directly measure client satisfaction, workplace culture, legal skill, diversity, employee happiness, or the quality of mentorship available to junior lawyers.
PEP also requires careful interpretation. It represents an average financial measurement rather than the guaranteed income of every partner.
Readers should therefore combine ranking data with independent research when comparing firms.
Future of the Am Law 100
The legal market continues to change as firms compete for major clients and experienced lawyers. Mergers, technology adoption, higher billing rates, and competition for top partners can reshape the rankings from one year to another.
Generative AI may become particularly important as firms search for new ways to increase efficiency. At the same time, clients may demand greater value and clearer pricing for sophisticated legal services.
The am law 100 will remain an important benchmark because it provides a yearly picture of how the largest U.S. law firms perform financially.
