Practice Overview

Antitrust Litigation, Regulatory Clearance and Advisory

Clients turn to Cravath to handle their most important antitrust work based on the Firm’s exceptional experience and long track record of success in high‑stakes, complex and precedent‑setting matters. Our antitrust practice covers regulatory, litigation and investigations work, and we have played a central role in many of the most significant, industry‑shaping antitrust matters in recent history, including U.S. v. IBM, U.S. v. AT&T and U.S. v. American Express.

Merger Clearance

We handle regulatory clearance for some of the world’s largest transactions, including in recent years advising on Anheuser‑Busch InBev’s $123 billion acquisition of SABMiller and British American Tobacco’s $97 billion merger with Reynolds American. We regularly interface with competition agencies and recognize that advisory work can present some of the most complicated and unusual antitrust issues for a company. We work closely with clients to develop a deep understanding of their business, positioning us not only to provide the “answer,” but also to assist each client in finding the right and workable business solution.


Our antitrust litigation practice brings to bear courtroom excellence and government experience to deliver the most comprehensive, innovative and tactical antitrust advice to our clients around the world—from initial investigation through final appeal. We handle antitrust litigation covering the entire spectrum, from managing class actions spread across the country to handling individual actions in a single jurisdiction. We also excel at bet‑the‑company enforcement actions, trying and winning cases against the government. Trained as generalists, our litigators see the broader picture and are able to navigate the intersection between antitrust law and other areas, including securities and intellectual property, to devise and deliver creative solutions for our clients.


In addition, we handle a variety of public and non‑public antitrust‑related governmental investigations in the United States and around the world, including investigations related to transactions and allegations of price fixing, coordination in output, monopolization and industry‑wide conspiracy.


Named Chambers USA’s “Antitrust Law Firm of the Year” in 2019, Cravath’s antitrust practice is regularly recognized by leading industry publications, including Chambers USA, Chambers Global and The Legal 500 US. We were recognized as a Law360 “Competition Practice Group of the Year” for 2019 and the Financial Times recognized Cravath in 2018 as “Most Innovative in Dispute Resolution” for our work on Ohio v. American Express. Our team has earned repeated praise from clients, the market and the press, including:

  • “They handle ‘cutting‑edge matters at the forefront of antitrust.’” Chambers USA
  • “[T]he cream of the crop. This is the firm to use if you are faced with high‑stakes antitrust litigation.” Client, U.S. News–Best Lawyers “Best Law Firms”
  • “Cravath, Swaine & Moore is one of the best antitrust firms in the US, with outstanding understanding of the relationship between IP and antitrust.” Qualcomm Head of Global Antitrust, U.S. News–Best Lawyers “Best Law Firms”
  • An “impressive and varied group that advises and litigates on antitrust matters, often with an international flavor,” whose “practitioners are well versed in the overlap between antitrust and other areas, such as securities and IP law.” Chambers USA
  • Cravath “combines a quick and thorough grasp of clients’ issues with the ability to communicate simply, clearly and completely.” Client, The Legal 500 US
  • “The U.S. Supreme Court decision in Ohio v. American Express offered more than redemption to one of America’s iconic companies, as well as to the team of trial lawyers from Cravath who took a 10‑year journey with their client to taste sweet victory. For AmEx, the case was a gutsy validation of its business model and of CEO Kenneth Chenault’s belief – not only in its exclusive card – but also in his Cravath team.” Lawdragon
  • “The two-sided markets theory the Cravath team persevered to wed with established antitrust law will likely change antitrust enforcement and competition in ways we can’t now envision. It’s certain to reverberate far beyond the credit-card industry.” Lawdragon
  • “It’s never easy to take on a long, costly battle with the government, but what’s at stake are some important issues: consumer choice, free market competition and the ability to deliver superior products and services to our customers. This is a fight worth fighting.” Kenneth Chenault, CEO of American Express, The Washington Post (emphasis added)
