Post Malone will be the final headliner at the 2026 March Madness Music Festival, Billboard can exclusively reveal.
The genre-bending superstar will close the night at Capitol One JamFest on Sunday (April 5) during Final Four weekend of the men’s college basketball tournament at American Legion Mall in Indianapolis, the NCAA, TNT Sports and CBS Sports announced.
Post joins previously announced headliners Twenty One Pilots and Zac Brown Band for the free, three-day festival. Russell Dickerson has also been added to the bill, joining Saturday’s Coca-Cola LIVE! lineup headlined by fellow country hitmakers Zac Brown Band.
Also just announced: the new after-hours event Madness After Dark, a Saturday night (April 4) party from 10 p.m. to 2 a.m. that will feature a performance by The Chainsmokers at the Indiana Roof Ballroom. (Capitol One cardholders will have access to priority registration for Madness After Dark GA tickets starting Wednesday at 10 a.m. ET.)
If you’re not in Indy for Final Four weekend, fans can stream live performances from the festival Friday, Saturday and Sunday on NCAA.com. Most fans might not know yet whether they’ll be in town, as the March Madness pool got down to its Sweet 16 teams as of Sunday night. After next weekend’s games, the 2026 Final Four will emerge.
Below, find the full lineups for all three days of the March Madness Music Festival, also including previously announced performers Megan Moroney, Ravyn Lenae, Dominic Fike, BRELAND, keshi and Joey Valence & Brae.
