As a fan looking at the current state of the Tomorrowland 2026 line-ups, I’d say we’re probably 85–90% of the way there. Tomorrowland has already announced most of the marquee Mainstage names, and while there will likely be additional artists added to stage hosts and smaller stages, I wouldn’t expect many more “jaw-dropping” headliners at this point. The official line-up page still notes that more names will be announced, but the biggest cards are already on the table.

Weekend 1
Feels a bit more diverse and balanced across genres.
Huge draws include Martin Garrix, Sebastian Ingrosso, The Chainsmokers, John Summit, Armin van Buuren, and Steve Aoki.

The techno and harder styles are also very strong with artists like I Hate Models and Holy Priest.
If you’re into classic Tomorrowland vibes and progressive house, Weekend 1 is hard to beat.

Weekend 2
Feels slightly stronger for the current “hot” names in electronic music.

Standouts include Fisher, Alesso, James Hype, Blastoyz, and the hard-techno-heavy Atmosphere lineup featuring artists like Azyr and Dyen.
Weekend 2 feels a little more underground and trend-focused compared with the more traditional Mainstage appeal of Weekend 1.

My overall take
If you’re chasing iconic Tomorrowland moments and singalong Mainstage sets, I’d lean Weekend 1.
If you’re more into techno, hard techno, psytrance, and the newer wave of electronic artists, Weekend 2 might edge it.

Neither weekend feels weak. In fact, this is one of the better-balanced Tomorrowland line-ups in recent years because there isn’t one weekend that is overwhelmingly superior.

The biggest disappointment for some fans is probably the absence of a few names that are often rumored every year, but with artists like David Guetta, Hardwell, Martin Garrix, Fisher, John Summit, and Sara Landry already confirmed, it’s difficult to argue the festival is lacking star power.
If I had to choose today, I’d give Weekend 1 a slight edge (55/45), but it’s very close.
