Top 10 Law Firms in the USA: Best Proven Firms Like Baker McKenzie and DLA Piper

Picking from the top 10 law firms in the USA is a different exercise depending on who you are. A general counsel at a manufacturer needs a team that can handle a supply-chain dispute in three countries. A founder preparing for an acquisition wants deal lawyers who have closed hundreds of similar transactions. A law student wants to know where the training is strongest. All three are looking at the same short list of names, but for different reasons.

The leading law firms in the USA now operate at a scale that would have seemed unrealistic twenty years ago. In the 2026 Am Law 100, aggregate gross revenue reached about $178.95 billion, up 13 percent. Kirkland & Ellis, Latham & Watkins and DLA Piper kept the top three revenue spots, and firms with a global footprint, such as Baker McKenzie and DLA Piper, sit alongside the Wall Street and Chicago institutions that built American corporate law.

This guide covers ten firms that consistently appear at the top of revenue, headcount, and reputation rankings. For each one you will find its history, strengths, and the kind of client it suits best. The article also explains how the ranking was built, so you can judge the list for yourself.

How We Chose the Top 10 Law Firms in the USA

Any list of the best law firms in the USA involves judgment, so the method matters. The selection here draws on four measures:

1. Gross revenue, taken from the Am Law 100, the closest equivalent to a Fortune 500 list for American law firms.
2. Headcount and geographic reach, which matter for multinational work.
3. Practice depth: M&A, litigation, tax, intellectual property, regulatory, and finance.
4. Market reputation among clients, recruiters, and peer firms.

This is a curated shortlist, not a strict ranking by a single metric. Revenue figures differ by source and by year, so treat any number as a snapshot. For current data, check the original Am Law 100 coverage from the ABA Journal.

The Top 10 Law Firms in the USA at a Glance

1. Kirkland & Ellis: The Revenue Leader Among Top Law Firms in the USA

Founded in Chicago in 1909, Kirkland & Ellis has become the biggest name in American corporate law. The 2026 results made it the first firm to pass the $10 billion mark, with $10.556 billion in revenue, up nearly 20 percent from the prior year.

Why Kirkland Stands Out

• Private equity dominance: The firm acts for a large share of the major buyout sponsors, and that relationship drives a steady flow of deals.
• Restructuring and bankruptcy: Few firms match its bench in distressed situations.
• Litigation strength: Its trial team handles high-value commercial and intellectual property disputes.

Kirkland suits sponsors and portfolio companies that want transaction speed and a team that has seen the same structure many times before. It is also known for demanding hours and high pay for associates.

2. Latham & Watkins: A Global Powerhouse in Capital Markets

Latham & Watkins began in Los Angeles in 1934 and now sits firmly in second place. Its gross revenue is around $8.3 billion, and no other firm besides Kirkland has reached that level.

Core Strengths

• Capital markets: IPOs, debt offerings, and structured finance are signature work.
• Mergers and acquisitions: The firm has a strong record in cross-border and public-company deals.
• Environmental and energy law: A long-standing practice that has grown with the energy transition.

Latham works well for issuers and underwriters who need coordinated advice across New York, London, and Asian offices.

3. DLA Piper: Scale and Reach Among the Best Law Firms in the USA

DLA Piper is the third-largest firm by revenue, at roughly $4.58 billion. It formed in 2005 from a merger of firms in the US and UK. As one commentator notes, it operates as a verein, a Swiss structure that links separate national partnerships under one brand.

What Sets DLA Piper Apart

• Presence in over 40 countries, which makes it a practical choice when a client has operations in many jurisdictions.
• Breadth of services: Corporate, real estate, intellectual property, employment, data protection, and government affairs.
• Headcount: It ranks among the largest firms by lawyer count in the Am Law 100.

DLA Piper is a strong fit for mid-market and multinational clients who want one firm across many regions without paying elite-boutique rates for every matter. Its data protection and privacy group is also widely used by technology and healthcare companies.

4. Baker McKenzie: The Original Global Law Firm

Baker McKenzie was founded in Chicago in 1949 and is often described as the first truly global law firm. It reports roughly $3.39 billion in gross revenue and about 4,595 lawyers in the figures most recently listed on Wikipedia’s revenue table.

Strengths of Baker McKenzie

• Cross-border transactions: Few firms have been operating internationally for as long.
• Tax and trade: Transfer pricing, customs, and sanctions advice are consistent strengths.
• Employment and compliance: Multinationals use the firm to harmonize policies across dozens of countries.
• Emerging markets: Offices in Latin America, Africa, and Asia give it local credibility.

If your legal problem crosses borders, Baker McKenzie belongs near the top of the list. Like DLA Piper, it operates under a verein structure.

5. Skadden, Arps, Slate, Meagher & Flom

Skadden helped invent the modern merger practice in New York during the 1970s and 1980s. It remains a first call for the largest, most complicated public-company deals.

• Mega-mergers and takeover defense: Boards facing hostile bids often hire Skadden.
• Regulatory and antitrust: Deep experience before federal agencies.
• White-collar defense: Investigations and enforcement actions are a major strength.

Skadden consistently ranks near the top of the Am Law 100 by revenue, and it is one of the most selective firms for new associates.

6. White & Case: International Arbitration and Project Finance

White & Case, headquartered in New York, was founded in 1901 and is built around international work. Wikipedia’s table lists it near $3.32 billion in revenue with about 2,598 lawyers, which gives it a very high revenue-per-lawyer figure.

• International arbitration: Regularly ranked among the leading practices in the world.
• Project and energy finance: Pipelines, power plants, and infrastructure deals.
• Sovereign and emerging-market clients: Governments and state-owned companies hire the firm for sensitive matters.

White & Case is the better choice when the other side is a foreign state or when a dispute will be heard in an international tribunal.

7. Sidley Austin: Regulatory and Financial Services Expertise

Sidley Austin, based in Chicago, is among the firms that hold a place in the Am Law 100’s top 10 for gross revenue. It is particularly respected for work in banking and securities regulation.

• Financial services: Advice for banks, asset managers, and insurers.
• Appellate and Supreme Court practice: A reputation built over decades.
• Life sciences and healthcare: Regulatory and transactional support for pharmaceutical companies.

Sidley suits regulated businesses that need counsel who understand supervision from the inside.

8. Ropes & Gray: Healthcare, Life Sciences, and Private Equity

Boston-founded Ropes & Gray reports approximately $3.4 billion in revenue, placing it just ahead of Baker McKenzie in the table cited above.

• Life sciences: Patent litigation and licensing for biotech and pharma companies.
• Private equity and asset management: A leading practice on both fund formation and deals.
• Healthcare: Compliance, transactions, and government investigations.

For a pharmaceutical or medical-device company, Ropes & Gray is often the first name suggested.

9. Morgan Lewis & Bockius: Labor, Energy, and Technology

Morgan Lewis, founded in Philadelphia in 1873, is among the largest law firms in the USA by lawyer count. It has built its reputation on practical, business-minded advice.

• Labor and employment: One of the largest teams in the country.
• Energy and infrastructure: Strong in regulation and transactions.
• Technology and outsourcing: Contracting and intellectual property for software and platform companies.

It is a sensible choice for employers dealing with workforce issues across many states.

10. Jones Day: Litigation and Government Relations

Jones Day, headquartered in Cleveland and Washington, operates as a single integrated partnership, which is unusual for a firm of its size. That structure lets it staff matters across offices with little friction.

• Complex litigation: Class actions, securities, and commercial disputes.
• M&A and capital markets: A deep transactional bench.
• Government and regulatory: Strong ties in Washington and in state capitals.

Jones Day often appeals to clients that want a single point of accountability across many offices.

What the Top Law Firms in the USA Have in Common

Despite different histories, the top law firms in the USA share several traits:

• Premium pricing backed by results: Clients pay high rates because the firms deliver on high-stakes work.
• Talent investment: Rising associate and partner pay competes for the best graduates.
• Technology adoption: Many firms now use AI tools for document review, research, and contract analysis, a trend noted in coverage of pressure from AI-driven efficiency tools on the industry.
• Concentration at the top: Revenue and profit are gathering at a small group of firms.

How to Choose Among the Best Law Firms in the USA

A famous name is not always the right match. Use this checklist:

1. Match the matter to the firm. A patent case, a cross-border tax issue, and a leveraged buyout need different teams.
2. Check the individual lawyers, not just the brand. The partner who will run your matter is what counts.
3. Compare billing models. Hourly rates, capped fees, and fixed fees can change total cost significantly.
4. Look at conflicts. Large firms may already act for a competitor or counterparty.
5. Consider geography. A global issue favors Baker McKenzie or DLA Piper, while a Wall Street transaction may favor Skadden or Kirkland.
6. Ask for references from clients with similar problems.

Large Firm or Boutique?

Many clients use a large firm for a broad program and a boutique for a single high-stakes matter. The two approaches complement each other.
