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.
13. Frank Ocean
It's been four years since Frank Ocean released 'Blonde' and it's heavily rumoured that his followup, perhaps titled 'FO5', will be released at the end of 2025. He'll be presumably touring it and may favour festival slots over a solo tour in Europe. He's never played TRNSMT, but was at T in the Park way back in 2013. | Getty Images
