More than two months before the calendar turns, a meaningful share of 2027's touring business has already been sold. Oasis moved all 42 dates of its next reunion leg in a single weekend. Zach Bryan is adding stadiums a week after his onsale. Olivia Rodrigo is booked into double-digit residencies at three of the world's busiest arenas. And a 20-year-old British singer with one album out has sold more than 135,000 theater tickets.

What follows is a ranking of the five biggest 2027 tours in each of three venue tiers — stadiums, arenas and theaters — weighted toward runs that are already mostly sold out. Because none of these shows have played yet, there are no Boxscore grosses to lean on. The numbers here come from promoter announcements, onsale outcomes and, where 2027 data hasn't surfaced, the artist's most recent comparable leg. Where the evidence is thin, we say so.

Nothing in 2027 touches the Gallaghers. All 42 shows across the U.K., Ireland, Europe and the U.S. sold out during three days of onsales Sept. 25–27, and the band says no more dates will be added. The routing includes 11 nights at Manchester's Etihad Stadium and six at Knebworth, where capacity runs about 125,000 per night — roughly 750,000 tickets from that one field alone.

The ticketing design is as notable as the demand. There was no general onsale. Fans pre-registered, and randomly selected registrants received unique, non-transferable codes for one of nine onsale windows. Resale is limited to Ticketmaster and Twickets at the original price paid. At Gillette Stadium, seated tickets ranged from $122.65 to $541.05 all-in, with standing tickets at $328.25 and $388.65.
