Top Antitrust Defense Lawyer Catie Ventura Joins Quinn Emanuel to Help Power Dynamic Practice

August 31, 2026
Firm News

Catie Ventura is a top litigator specializing in civil antitrust defense, fresh off a triumphant dismissal in a sprawling wage-fixing case against every nuclear power generation company in the U.S.  

Quinn Emanuel is supercharging its successful antitrust practice, an increasingly important part of the world’s biggest disputes-only law firm. 

It was a match made in Washington. 

Ventura, acclaimed for tackling complex litigation often involving novel questions of law, has now walked across the street from Kirkland & Ellis to join Mike Bonanno, Chair of Quinn Emanuel’s Antitrust Investigations Practice and Co-Chair of its Antitrust Defense group. Catie told us she’s excited to help Mike and the firm take the bustling practice to the next level.  

Here’s a taste of Catie’s big wins and ambitions, and how her focus on the human element in legal disputes has helped her serve her clients so well. 

Groundbreaking Cases and a Trend to Watch 

Welcome, Catie! You’re in the middle of a distinguished career. Any way we could get a veteran litigator to talk about a win or two?

Well, in addition to our recent win in the nuclear power wage-fixing case, I represented the very first company ever criminally indicted for a no-poach conspiracy [in which companies secretly agree not to recruit and hire each other’s employees], in a case brought by the Department of Justice in 2021. That case was ultimately voluntarily dismissed by the DOJ. In another criminal no-poach case, we helped get one of the first directed verdicts against the DOJ in decades. 

What’s the most important trend you’ve seen in the government’s pursuit of competition cases in the past couple of years, and where do you see it going? 

I think the biggest change right now is that state AGs are getting much more active, filling what they view as a gap in federal enforcement. A unique aspect of state AGs is the local political motivations driving their enforcement actions. You have to ask: Why are they doing this? In part, they see an antitrust problem and they want to solve it. But what’s the political why – how is this problem impacting their constituents in a unique way, and how can you address it? That will be a crucial piece of the puzzle when resolving state AG matters. 

Cutting to the Core 

You’re known for your ability to master highly complex matters and to explain them to clients and courts. What was your most memorable challenge in that area?  

Our motion-to-dismiss win in the nuclear wage-fixing class action is a great example of this. The complaint was 100-plus pages, against more than 20 defendants, based on more than 20 confidential witness statements – it was an enormously complex complaint. And our job was: How do we simplify this and get to the two or three key points the judge needs to know to give us the win here? Working with the team from Quinn Emanuel (who represented a different defendant), I was a key architect of that strategy and that brief. 

How do you find those two to three crucial winning points? 

You’ve got to really understand the nuances of antitrust law. There are 10 legal arguments you could make, but which are the winners, where you’re going to focus your time and energy? You know, judges are super smart people, but they don't all have experience in antitrust law. So how can I explain this to them in a way that’s teaching them the law and giving them the tools they need to dismiss a case or give us a win on class certification or summary judgment? 

Next Big Thing 

What’s the biggest thing in antitrust right now?

Cases based on alleged information exchanges between competitors in an industry are very active right now. The challenge with these cases is that information exchanges are often pro-competitive. While the DOJ recently reached a settlement with Agri Stats that provides some guidance on this topic, there’s still a lot of law to be developed in this area, and vagueness that plaintiffs’ lawyers are trying to capitalize on right now. It’s a great opportunity as a defense lawyer to help craft that new law so companies understand where the line between pro-competitive information exchanges and anticompetitive information exchanges lies.  

$3 Billion and the Humans Behind It 

Quinn Emanuel has beefed up its pro bono program. You did some pro bono work early in your career. What did you take away from that work? 

It’s how I learned so many crucial skills that make me the lawyer I am today. I think I took my first deposition, presented at my first hearing, and had my first trial in a pro bono case. But the biggest takeaway from these matters is they bring you much closer to the human element of being a lawyer.  

With the multi-billion-dollar cases we handle, it’s obviously very different, but you still have to remember, who are the humans we’re dealing with? How does this case affect people on a personal level? You can’t forget the stresses that in-house counsel and clients are going through, especially when they are facing cases with risks in the hundreds of millions, if not billions, of dollars.  

Quinn Emanuel represents so many clients in bet-the-company cases. In addition to the dollars and cents, the emotional stakes are high. Somebody could lose the business they built, and all the employees working for them. So keeping that human element top of mind is so important to being a strong lawyer and helping our clients work through these complex matters.  

We’re so happy you’re here, Catie. To leave it on an antitrust note, what are you thinking about the firm and the practice right now? 

What drew me to Quinn Emanuel was the team’s enthusiasm and excitement about growing the antitrust defense practice and making sure they were a leader in the industry, able to get and win the best, most complex and challenging cases. I want to help make us the most formidable go-to firm for antitrust defense litigation.
