TRNSMT has taken place in Glasgow since 2017, when Radiohead, Kasabian and Biffy Clyro topped the bill.
It was a replacement for the much-missed T in the Park, bringing the music into the city centre to negate the need for camping.
Since then the likes of Queen, Arctic Monkeys, The Strokes, and Pulp have graced the stage - with local heroes Lewis Capaldi and Gerry Cinnamon cutting their teeth on the smaller stages.
This year saw 50 Cent, Biffy Clyro and Snow Patrol headline, but no dates have yet been revealed for the 2026 event, although the event website does say: “See you at TRNSMT 2026”.
It’s led to specualtion about the future of the event, and even rumours that T in the Park could return in its place at an as-yet-unspecified location.
If it does return - with the dates expected to be July 10-12 - then speculation is growing as to who could headline.
Here are 13 rumoured names for 2026.
5. The XX
It's been nearly a decade since The XX released their last album 'I See You' and played live. Since then they have been on haitus with various solo projects (often featuring each other) but have reportedly been working on a new album, recently performed on stage together at the LIDO Festival in London as part of Jamie xx's headline set, and have been confirmed for both Coachella and Primavera 2026. They are clearly taking festival bookings and so TRNSMT could be the perfect place for their return to Scotland. | Getty Images
6. Muse
It has been 15 years since Muse headlined T in the Park 2020 - the third time they had played the festival. The timings for a debut at TRMSMT could work for 2026 - they revealed new single 'Unravelling' in June and are expected to release their tenth studio album in the first half of next year. It'd certainly promise to be a spectacular show, with Matt Bellamy not known for his low-key performances. There will be drones. | Getty Images for iHeartRadio
7. Sabrina Carpenter
If the TRNSMT bookers want to have an all-out pop headliner then there are few bigger names in the world of music at the moment than superstar Sabrina Carpenter. She headlined Primavera last year, has a new album out in the shape of 'Man's Best Friend' and has already confirmed for Coachella 2026. She's yet to play an outdoor gig in Scotland so next year could just be the year. | Gareth Cattermole/Getty Images
8. Deftones
Fearsome rock band Deftones already have a Glasgow date set for next year at the OVO Hydro but that doesn't mean they can't also play TRNSMT - both Fontaines DC and Snow Patrol played both veunues in 2025. They have a well-received new album in 'Private Music' and have proven that they can headline by taking top billing at the Download Festival. | Getty Images
