Who's playing Worthy Farm, 23 to 27 June 2027? We went through 25 years of Glasto lineups, every big summer festival we could scrape, setlist.fm gig diaries and the bookies' prices, and turned it all into odds. Last updated .
The chance each act gets a big slot, meaning anywhere on the Pyramid or the top five on the Other Stage. The pale part of each bar is the range we'd believe. Tap a name to see what's pushing their number up or down, and their gig diary around Glasto weekend.
The current top eight. One point per update.
Every act the bookies have priced. Along the bottom is their chance of headlining, with the bookies' margin taken off. Up the side is our chance of any big slot. Headlining counts as a big slot, so most dots should sit above the dashed line. Anyone below it is someone the 2027 news has gone against.
We checked 2000 to 2025: artist-years across 40 festivals, against everyone who played the Pyramid or the top five on the Other Stage.

Does a gap in the tour mean Glasto?
Who's gigging when
We tested it the strict way: each year from 2007 is predicted using only the years before it, so it never gets to peek at the future. The festival effect also holds up in both halves of the data: three or more festivals is worth about × from 2000 to 2011 and × from 2013 to 2025, after allowing for fame.
Does 20% mean 20%?
Picks that came true, by year
Every act starts with a number from their track record: how often they've played the big festivals lately, and whether they've done Glasto before. Coming back after a few years off helps a lot more than having played the last one. If the bookies have priced someone to headline, their number can't drop below that, since headlining counts as a big slot.
Then each bit of 2027 news multiplies their odds by however much that kind of news mattered in the back-test. Booked for Rock Werchter? Glasto acts play Werchter far more often than lookalikes who don't get Glasto, so the odds go up. A gig in Texas on 26 June? They go down a lot. Ruled out by Emily Eavis? Near enough zero.
It isn't that clever. Predicting each year from earlier years only, its top 40 got about right a year, against for picking on fame and Glasto history alone. A festival-only number can't go above 60%, because nothing in the history backs up being surer than that. About 30% of Glasto's big acts didn't play any of the 40 festivals we track, so it never had a chance with them. Open'er and Mad Cool barely appear on Wikipedia, so we can't measure them; we count them like Werchter and Roskilde, since it's the same early-July run with mostly the same headliners. It's a bit of fun, not a betting system.
