The Am Law 100 is ALM/The American Lawyer's law firm ranking — per ALM's published description, a ranking of the 100 largest U.S. law firms by gross revenue.
Because the metric is revenue, the list measures firm size and business scale — not prestige, and not what any individual lawyer is paid.
Here is what the ranking measures, how it relates to the Am Law 200 and Vault's prestige list, and how to use rankings in your job search.
What does the Am Law 100 measure?
Per ALM's published description, the Am Law 100 is the American Lawyer's ranking of the 100 largest U.S. law firms by gross revenue.
Alongside the ranking, ALM says it reports two related figures for the firms on the list: revenue per lawyer and profits per equity partner (PEP).
Because the metric is gross revenue, an Am Law 100 position is a statement about scale — how much money the firm brought in across the whole firm.
It is not a statement about prestige, and it is not a pay figure for any lawyer at the firm.
When a firm describes itself as an "Am Law 100 firm," the claim is about its revenue rank.
Read that way, the label tells you something real — on ALM's description, the firm is one of the 100 largest U.S. firms by revenue — while saying nothing on its own about culture, practice depth or pay.
One transparency note: ALM's Am Law data sits behind law.com's paywall, so this page describes how the ranking works rather than reproducing its figures.
You won't find revenue cut-offs, firm-by-firm dollar figures or a ranked list here — for the current data, go to ALM's own Am Law coverage.
How this page treats ALM's data
Am Law 100 vs Am Law 200 vs Global 200
Start with what the name already tells you: the Am Law 100 is a list of 100 firms.
Search around the ranking and two sibling names appear — the Am Law 200 and the Global 200.
The names are easy to find; what each list measures is a separate question.
Here this page's research reaches its limit.
What it found for the Am Law 100 is ALM's own description — the 100 largest U.S. law firms by gross revenue — which it could not check against the paywalled data.
It found nothing on how the Am Law 200 or the Global 200 are constructed — what size range each covers, whether the scope is U.S. or worldwide, or how the criteria differ from the 100's.
The practical consequence: don't treat the three names as interchangeable tiers.
"Am Law 200 firm" and "Global 200 firm" are different claims from "Am Law 100 firm," and without the criteria in hand you can't tell exactly what either sibling list measures.
Check ALM's site for each list's current methodology before you compare firms across lists.
What revenue and PEP tell a job seeker
The figures behind the ranking answer different questions.
Gross revenue says how big the firm's business is.
Revenue per lawyer spreads that revenue across the firm's lawyers.
Profits per equity partner is the partner-level figure — profit per equity partner, not a salary any associate or staff member receives.
For a job seeker, the key is what these numbers do not say.
None of them is your offer, and none of them measures prestige — that is a different measurement entirely.
Vault's 2026–2027 prestige rankings surveyed more than 20,000 U.S. associates between October 22, 2025 and January 23, 2026, having them rate firms other than their own on a 1–10 prestige scale, with firms ranked by average score.
Vault's list measures perceived prestige, not profits or size — the mirror image of a revenue ranking.
And none of the ranking figures sets associate pay.
Pay comes from the market and each firm's own scale, and it moves.
NALP's 2025 Associate Salary Survey found a median first-year associate base salary of $200,000 as of January 1, 2025, and $215,000 at firms of more than 700 lawyers; at firms of 250 or fewer lawyers, the most common reported first-year salary was $150,000 or less (44% of offices).
Those are survey figures with their date attached — not a current scale.
One update since that survey: legal press reported that Milbank set a new market base scale by memo on June 2, 2026, effective July 1, 2026, starting at $235,000 for first-year associates, and that other large firms matched it.
Those reports are secondary, so treat the scale as press-reported market context and check a specific firm's current terms.
How the large-firm pay structure fits together is its own subject: see our BigLaw guide.
How to use rankings when choosing a firm
"Top law firms" means different things to different people: the biggest law firms by revenue, the firms peers rate most prestigious, the firms that pay the most.
Those are three different measurements, and matching the list to your question is the whole skill.
Rankings are one input into a longer attorney careers decision — use a revenue ranking for a read on scale, a prestige survey for a read on peer perception, and pay data for a read on compensation.
A few habits make the lists more useful:
- Decide what you are screening for first — scale, prestige, practice fit or pay — and pick the measure that matches.
- Read the metric behind a rank, and its date, before you read the position.
- Check the publisher's current methodology — Vault describes its survey, and ALM's details sit behind its paywall.
- Weigh what no ranking measures — practice area, office, team, training and the work itself — which you learn from the posting and the interviews.
Remember what a ranking excludes.
Per ALM's description, the Am Law 100 ranks 100 firms by revenue; a revenue rank is not a judgment of any firm — on the list or off it — on culture, training or the quality of its work.
Treat a rank as one data point about scale or prestige, and let the posting, the interview and your own priorities decide the rest.
Ranking editions are dated, too — the Vault edition this research read is 2026–2027 — and publishers may update their methods.
Before you compare a firm's rank across years or across lists, check the publisher's site for the current edition.
