Who Is Opening for Mumford & Sons on the 2026 Prizefighter Tour?
Updated August 24, 2026 with the fall leg openers, the added second Kia Forum night, and the new Shoreline Amphitheatre closer.
Mumford & Sons are touring North America in 2026 behind their album Prizefighter, and the support bill reads like a who's who of current folk and Americana. The run opened June 2 in Vancouver, and the North American headline dates now close October 8 at Shoreline Amphitheatre in Mountain View after the band added a second Kia Forum night and a Bay Area stop. Openers rotate by leg rather than one act carrying the whole tour. Here's who plays which stretch and what to expect.
How the Lineup Works
The Prizefighter Tour is split into seasonal legs, and each leg has its own opener or pair of openers. Dylan Gossett anchored the early-June run, with Sierra Ferrell, Caamp, and Lord Huron joining for specific dates. Medium Build covered the late-summer leg. For the fall, the Marcus King Band opens the September headline dates and Sierra Ferrell returns to close out the tour in October. Because the support changes from city to city, the opener is worth checking against your specific date.
Dylan Gossett
Dylan Gossett opens the bulk of the early-June dates, the longest single stretch of support on the tour. The Texas singer-songwriter broke out with "Coal" and has built a rugged, acoustic-driven sound that fits squarely in the Mumford & Sons lane. For most of the opening leg, he is the act warming up the room.
Sierra Ferrell
Sierra Ferrell joined for select early-June dates, including the Boulder show, and she returns to close the tour: she opens the final four headline dates, Albuquerque (October 3), both Kia Forum nights in Inglewood (October 6-7), and the Shoreline Amphitheatre closer in Mountain View (October 8). The West Virginia artist has become one of the most acclaimed names in modern Americana, with a vintage, genre-spanning style that pulls from old-time country, folk, and bluegrass. Her sets are a highlight wherever she lands on the schedule.
Caamp
Caamp support a pair of June dates, including Chicago and Toronto. The Ohio folk band built a devoted following on warm, banjo-forward indie-folk, and they are comfortable at the scale of these rooms after years of steady touring. They are one of the closest stylistic matches to the headliner on the whole bill.
Lord Huron
Lord Huron take the Hershey and Boston dates in June. The Los Angeles band trades in cinematic, reverb-soaked indie-folk and had a major resurgence on the back of "The Night We Met." On a Mumford & Sons stage, their atmospheric sound gives the early-evening slot real weight.
Medium Build
Medium Build covers the late-July and August leg, from Minneapolis through stops including Atlanta, Tampa, Charlotte, New York, and Gilford. The Alaska-raised, Atlanta-based artist has been one of the more talked-about rising indie names, and this run is among his largest stages to date.
Marcus King Band
The Marcus King Band open the September headline dates: Charlottesville (September 20), Grand Rapids (September 22), Madison (September 23), Birmingham (September 29), and The Woodlands (October 1). Marcus King is a blistering guitarist and soulful vocalist whose blues-rock pedigree adds a different texture to the bill, leaning heavier and groovier than the folk acts on the earlier legs.

| November 20 | Mexico City, Mexico | Corona Capital | Festival |
Four of the remaining stops are festival plays, Rock in Rio, Sea.Hear.Now, Bourbon & Beyond, and Oceans Calling, plus a Corona Capital slot in Mexico City on November 20, so those nights follow the festival's own lineup rather than the tour's support bill.
What to Expect
The Prizefighter Tour mixes the band's new material with the festival-ready singalongs that made Sigh No More and Babel arena staples. The routing included marquee stops at Madison Square Garden, Wrigley Field, and Fenway Park, and the added Kia Forum and Shoreline dates give the West Coast a proper sendoff. With a support bill this deep in folk and Americana talent, the opener is a real part of the night on every date, so it pays to arrive early.
