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.
And the rumours have intensified this week after organisers confirmed when tickets would go on sale and how much they will cost - the answers being on October 1 and £408.
Here are the 11 most likely headliners on of the three nights on the Pyramid Stage, according to the bookies.

1. Harry Styles - 1/2
Harry Styles' 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 - something that's only been confirmed with his current 30-night residency at New York's Madison Square Gardens.

2. Sam Fender - 6/4
Sam Fender has already proven himself as a festival headliner and should have a new 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 6/4 second favourite to bag one of the three headline slots. | Getty Images
3. Taylor Swift - 2/1
Arguably the biggest artist on the planet at the moment, Taylor Swift has never played Glastonbury - her headline slot in 2020 was cancelled due to the pandemic. She's sure to be near the top of Emily Eavis' wishlist and is now the 2/1 third favourite to finally headline. | Getty Images
4. Sabrina Carpenter - 5/2
Sabrina Carpenter has never played Glastonbury and is certainly a big enough name following the huge success of her last album 'Man's Best Friend'. She's a 5/2 shot to take one of the top spots at the world's most famous music festival next year. | Getty Images for iHeartMedia
