Short answer: if you want the safest “top brand” shortlist for U.S. corporate law, start with Wachtell, Cravath, Skadden, Latham, Kirkland, Sullivan & Cromwell, Davis Polk, Simpson Thacher, Paul Weiss, Gibson Dunn, Cooley, Wilson Sonsini, Fenwick, Goodwin, and Gunderson Dettmer — then choose based on the type of corporate work. Law-firm quality is very practice/partner-specific, so the “best firm” for a Fortune 100 merger is not always the best firm for a startup financing.

Best overall U.S. corporate-law brands

My top “actually used” recommendations

1. Wachtell, Lipton, Rosen & Katz — the classic boardroom / high-stakes M&A brand. Best when the matter is strategic, sensitive, or existential.
2. Cravath, Swaine & Moore — elite Wall Street corporate, M&A, governance, securities, and financing work; also the No. 1 Vault prestige firm in 2026–2027. (prnewswire.com)
3. Skadden — one of the most recognizable corporate/M&A and capital-markets brands; strong for large public-company deals and complex transactions.
4. Latham & Watkins — arguably the best “one firm for everything” corporate platform: M&A, capital markets, finance, PE, restructuring, tech, life sciences, and cross-border scale. Vault says Latham is No. 1 in Securities/Capital Markets for 2026–2027, and GlobalData reported Latham as the top 2025 M&A legal adviser by deal value. (prnewswire.com)
5. Kirkland & Ellis — the dominant private-equity / sponsor-side brand and one of the most used corporate firms by sheer market volume. It ranked No. 1 in Am Law by gross revenue and No. 6 in Vault, and Vault lists it as No. 1 in Private Equity, Bankruptcy/Restructuring, and Banking & Financial Services for 2026–2027. (counselcontacts.com)
6. Sullivan & Cromwell — elite public-company M&A, capital markets, governance, banking, and regulatory-adjacent corporate work.
7. Davis Polk & Wardwell — top-tier for capital markets, public-company work, M&A, and financial institutions.
8. Simpson Thacher & Bartlett — elite for private equity, M&A, fund sponsors, credit, and capital markets.
9. Paul, Weiss — excellent for large-cap public M&A, private equity, activism/defense, and board-level matters.
10. Gibson Dunn — broad national corporate platform with particularly strong regulatory/litigation backup for complex transactions.

Chambers’ current U.S. nationwide Corporate/M&A: The Elite Band 1 list includes Cravath, Davis Polk, Kirkland, Latham, Paul Weiss, Simpson Thacher, Skadden, Sullivan & Cromwell, and Wachtell, which is a strong validation of the core “elite corporate” shortlist. (chambers.com)

If you’re a startup or growth company

Do not automatically hire Wachtell/Cravath/Skadden for routine startup work. For formation, SAFEs, preferred-stock financings, option plans, VC rounds, startup M&A, and IPO prep, the firms people actually use are usually:

• Cooley
• Wilson Sonsini
• Fenwick
• Goodwin
• Gunderson Dettmer

Chambers’ nationwide Startups & Emerging Companies Band 1 group includes Cooley, Fenwick, Goodwin, Wilson Sonsini, and Gunderson Dettmer. (chambers.com) Cooley also reports being the No. 1 firm for companies raising venture capital in the U.S. and globally in PitchBook’s 2025 league tables, while Gunderson reports being the most active VC law firm globally in PitchBook’s 2025 tables.

• For private equity: call Kirkland, Simpson, Latham, Ropes, Weil, Debevoise, Goodwin.
• For startup / VC: call Cooley, Wilson Sonsini, Fenwick, Goodwin, Gunderson.

The "best" corporate law firms in the US are typically elite "BigLaw" practices strong in M&A, securities/capital markets, private equity, corporate governance, and related transactional work. These are evaluated via prestige (Vault associate surveys), client/peer rankings (Chambers), revenue/profitability (Am Law 100), and real-world usage by Fortune 500 companies, private equity firms, and other major clients.

Rankings are subjective and can shift yearly, but consistent standouts emerge from 2025–2026 data (reflecting 2025 performance). "Top brands people actually use" refers to firms frequently retained for high-stakes deals—often the most prestigious or largest by revenue/headcount, as they handle the biggest transactions.

Recommendations depend on your needs (e.g., deal size, industry like tech/PE/energy, location, or budget). Elite firms like Wachtell or Cravath command premium rates and selectivity; larger ones like Kirkland or Latham offer scale and breadth. Check current Chambers/Vault profiles or consult in-house counsel networks for fit, as client relationships drive most hires. Rankings evolve—review the latest Vault, Chambers USA, or Am Law reports for updates. For specific matters, peer referrals or direct outreach are common.
