Glastonbury – the UK’s wild, muddy, soul-stirring festival that’s been a brand-free haven for decades. Or at least, it was, writes Kaitlyn Gronek, director of communications at Sprout Social.

This year, something shifted.

Social media exploded with festival content, and brands found a way in, capturing the Glastonbury vibe without triggering the authenticity alarm.

How? Influencer marketing, the not-so-secret weapon that’s rewriting the rules for marketers who want to connect in more genuine, relatable ways.

Influencer marketing isn’t just a buzzword anymore, it’s a powerhouse for brands.

Our data shows 90% of marketers agree that influencer content outperforms organic brand content in engagement, while a further 83% say it drives better conversions.

So, it’s no surprise that brands saw Glastonbury, the pinnacle of UK festivals, as a prime opportunity to ride the wave of influencer hype and tap into a cultural moment.

Glastonbury’s anti-brand roots vs the influencer effect

Glastonbury ass always been the rebel kid, turning away from corporate messaging with strict no-brand zones and no free passes for influencers.

It’s been about the music, not logos.

But this year the social feeds told a different story. Influencers were everywhere, and brands were right there with them, weaving their way into the festival’s story without stepping on its soul.

We dug into the Instagram data from influencers that attended Glastonbury, along with brands posting sponsored content tied to the festival.

The results speak volumes.

The earned media value (EMV) from Glastonbury-related content makes it clear that brands are ramping up their presence at the festival, using influencers to resonate with consumers and produce content that feels authentic.

Sustainable backpack brand, Roka, understood the assignment showing up subtly without disrupting festival goers experience.

They partnered with fitness influencer Mary McCarthy for a “pack with me” video before Glastonbury’s gates even opened.

Roka’s festival-ready bags blended into Mary’s content so smoothly, you’d think they were just part of her prep. No hard sell, just a subtle flex that lets fans discover the brand organically.

Sprout’s 2025 Q2 Pulse Survey shows authenticity as the number one driver of online engagement, especially among younger generations.

In fact, 19% of Gen Z are more likely to call out brands for inauthentic influencer campaigns, which means that brands looking to work with influencers need to make sure they are activating the right partners to build trust and connection with audiences.

Burberry led the way on this by leaning into the nostalgia and spirit of the festival with its Instagram post featuring Alexa Chung wearing Burberry wellies, a nod to Kate Moss’s iconic 2005 Glastonbury look.

It wasn’t just a post, it was a moment that resulted in an estimated $100,389.34 (£74,076) in media value, which is the equivalent of nearly 200 Glastonbury tickets.

Learning from Coachella’s billion-dollar playbook

If Glastonbury’s dipping its toes into the influencer pool, Coachella’s already diving in headfirst. In April 2025, brands like Revolve racked up $1.4 billion (£1bn) in EMV across Coachella’s two weekends. That’s the kind of potential brands are looking to tap into at Glastonbury. It’s not just about slapping a logo on a festival wristband—it’s about creating content that feels like it belongs, through influencers who get the crowd.

With Glastonbury taking a fallow year in 2026, brands have time to plan for 2027. But this isn’t just about jumping on the bandwagon because everyone else is.

Sprout’s research shows 95% of UK social media users want brands to keep up with online culture.

Free People got this right at Glastonbury’s VIP pop-up hotel, dressing festivalgoers in their boho-chic fits that screamed the quintessential free-spirited vibe of Glastonbury.

If you’re a marketer eyeing Glastonbury 2027, here’s the real talk:

• Pick the right influencers. They need to align with your brand and the festival’s ethos. A mismatch will land you in deep waters.
• Give your team some creative freedom. Let them move fast and adapt to the moment, Glastonbury is too dynamic for rigid playbooks.
• Stay authentic. If your brand doesn’t fit the festival’s soul, you’ll quickly be called out. You don’t have to have a presence if it doesn’t feel authentic to your brand.

Influencer marketing could be your key to breaking through at Glastonbury, but it’s not a free pass.

Done right, it’s a powerful way to connect with fans, spark conversations, and make your brand part of a cultural moment.

Done wrong? You’re just another brand trying too hard. So, start planning now, 2027’s going to be a wild ride.
