The 2025 Lawdragon 500 Leading Global Antitrust & Competition Lawyers

Mike Bonanno of Quinn Emanuel, Stacey Slaughter of Robins Kaplan and Leslie Overton of Axinn.

We’re thrilled to introduce our inaugural guide to the elite lawyers parrying for an equal playing field for corporates and consumers worldwide – The 2025 Lawdragon 500 Leading Global Antitrust & Competition Lawyers.

These lawyers excel in crafting transaction terms that will pass muster with global regulatory bodies. They know how to navigate a growing array of worldwide authorities who examine the impact of a deal in hotly contested industries. Their clients regularly face investigations that threaten a deal – and when they fail, a merger can be killed. And, of course, they know how to go to court for damages or to protect a faltering merger.

It’s a truly global practice with the world’s largest corporations facing a boggling array of seemingly contradictory demands in important markets worldwide. What’s OK in Washington, D.C., may not pass the EU standards in Brussels; these lawyers make sense of a global approach to corporate regulation that is inconsistent, at best. And certainly evolving.

It is, of course, subject to political winds. And, in the U.S. – where most of this inaugural guide is based – you don’t need a weatherman to anticipate a shift in oversight, especially of the industry most in the crosshairs: Big Tech.

We created this guide through our time-honed process combining nominations with journalistic research into the lawyers and firms leading the way in antitrust and competition. Honorees who are also in our esteemed Hall of Fame are noted with an asterisk. It is our first of 23 practice-focused guides we will publish this year. We are proud to offer this expanding array of our guides, with an ever-fresh take on leading lawyers.
