What CMOs can expect from Cannes Lions 2025

Every June, the global marketing and advertising world descends on the French Riviera for Cannes Lions for a week of creativity, big ideas and even bigger conversations. And while the backdrop may be glamorous, for CMOs, the real value of Cannes goes far beyond the Croisette.

If you’re planning to attend this year (or just thinking about it), here’s a look at what you can expect, and why Cannes Lions continues to be one of the most important events on the calendar for senior marketing leaders.

One of the biggest reasons CMOs show up at Cannes? To get a sense of where the industry is going. 

This year’s agenda is packed with sessions that go deep on AI, creative effectiveness, brand purpose, media disruption and marketing accountability; all critical issues for marketing leaders today.

You’ll hear from a mix of global CMOs, creatives, tech executives and analysts who are shaping what marketing will look like in the next 12–18 months. So other than some great views, it’s a chance to get out of the weeds and think strategically.

Yes, the setting is gorgeous. But the connections you make at Cannes might be the most valuable part of the experience. 

Whether it’s a breakfast hosted by a major platform, a closed-door CMO roundtable or a chance meeting over drinks at the Ad Age Lawn Party, Cannes is a hub for authentic conversations with people who get your world.

Expect to meet other CMOs, agency leads, media partners and creative innovators — many of whom are navigating the same challenges (and opportunities) you are.

The Lions awards are more than just a show. They’re a showcase of what’s working in modern marketing. Categories like creative effectiveness, innovation and brand experience are especially useful for CMOs who want to see how bold ideas are driving real business results.

You’ll walk away with fresh inspiration (and likely a few case studies to bring back to your team).

Cannes is also a place where the latest and greatest in martech and media innovation is on display. Big players like Google, Meta and Amazon will be there, alongside emerging tech companies showcasing how AI, automation and personalization are reshaping the way we engage with consumers.

If you're thinking about your next big tech investment, or just want to see what’s coming around the corner, this is a great place to start.

Cannes isn’t just about learning; it’s also a stage. For CMOs looking to raise their profile or amplify their brand’s voice, there are plenty of opportunities to do just that. You might be speaking on a panel, co-hosting an invite-only dinner or partnering with your agency to activate something creative along the Croisette.

Being part of the Cannes conversation helps position your brand (and your leadership) at the forefront of creativity and innovation.

This year’s programming is organized around five big themes:

1. Innovation unwrapped – AI, emerging tech and business transformation

2. Insights and trends – Consumer behavior, culture shifts and what’s next

3. The creativity toolbox – Practical ideas and creative tactics you can apply now

4. Talent & culture – Building creative teams and inclusive workplaces

5. Creative impact – Measuring what matters and proving marketing’s value

A few standout sessions:

• Serena Williams joining Reckitt to talk about impact-driven innovation

• YouTube CEO Neal Mohan reflecting on 20 years of YouTube and its creative evolution

• Ad Age Lessons from young creatives (featuring past Cannes Lions winners!)

• “Future Gazers” with top creative and media thinkers predicting what’s next

• AI showcase with VaynerMedia 

And if you’re dropping by ADWEEK House at Le Majestic, expect deep dives on topics like retail media, the creator economy and omnichannel strategy — all especially relevant for brand-side marketers.

Even if you’re not planning to be on the ground in Cannes, there are still plenty of ways to engage. Many of the biggest sessions will be streamed or shared online. You’ll find real-time recaps on LinkedIn, newsletters from your agency partners and coverage across the trade press.

If you’ve got a team attending, make sure they’re bringing back key takeaways. And if not, keep an eye out for post-event briefings that translate festival insights into action.

At the end of the day, Cannes Lions is more than a festival. It’s a strategic moment. 

It’s where creativity meets business outcomes. Where CMOs step out of execution mode and reconnect with big-picture thinking. Where brands see what’s possible and learn what’s next.

Whether you’re attending in person or tuning in from afar, there’s a lot to take away. This year’s event promises not just inspiration, but real tools and ideas you can bring back to your team.
