First held in 1970 as the Pop, Blues & Folk Festival - when just 1,500 people attended - Glastonbury has grown to become a major event in the British cultural calendar, with most of the biggest names in music having played it at least once.
Last year over 200,000 enjoyed headline sets from Neil Young, Olivia Rodrigo and The 1975, along with hundreds of other bands playing countless stages of all sizes - and millions watched the extensive television coverage.
As part of the green ethos of organisers Michael and Emily Evis, the event taking a break every five years to give the working farm some time to rejuvenate from the inevitable wear and tear caused - and this year was one such ‘fallow year’.
The resultant gap in 2026’s music festival has, if anything, only increased speculation as to who will be topping the bill in 2027.
The tickets went on sale earlier this month and sold out immediately - despite not a single act being announced.
If you managed to bag your spot at Worthy Farm, here are the artists you are most likely to see, with the bookies now seemingly pretty certain of all three acts that will top the bill.

1. Harry Styles - 1/5
Former One Direction singer Harry Styles is now the 1/5 favourite to headline Glastonbury. His record-breaking 12-night residency at London's Wembley Stadium proved that he is one of the biggest live acts in the world at the moment - and he's now repeating the trick with a string of shows at Madison Square Gardens in New York. He'd certainly be a popular choice. | Gareth Cattermole/Getty Images
2. Sam Fender - 1/3
Sam Fender has already proven himself as a festival headliner and should have at least one more album under his belt by the time Glastonbury 2027 comes around. If his career projectory continues at the current rate he'll be a huge hit on Worthy Farm. He's the 1/3 second favourite to bag one of the three headline slots. | Getty Images
3. Billie Eilish - 1/2
Last time Billie Eilish topped the bill at Glastonbury in 2022, at the age of 20, she became the festival's youngest headliner in history (with Sir Paul McCartney becoming the oldest the same year). She's expected to release a new album in the next few months and, with odds of 1/2, is strongly rumoured to be the third Pyramid Stage headliner. | Getty Images
4. Muse - 3/1
When it comes to dramatic live shows, few can beat the sci-fi rock stylings of Muse. They have already headlined Glastonbury on three occasions, in 2004, 2010 and 2014. They're 3/1 shots to return for a fourth time. | Getty Images
