KATSEYE has a Sziget date. What can fans book?

The festival’s official lineup data places KATSEYE on August 11, the second day of Sziget’s five-day run from August 10 through 14. Separately, Yonhap and CHOSUNBIZ reported on November 11, 2026, that HYBE–Geffen Records had announced the group as a headliner. The date has direct festival support; the headline designation rests on those agency-attributed reports.⁠67⁠31⁠56⁠57

That moves our reporting beyond the first announcement. On November 10, HeyDay News reported KATSEYE’s inclusion among the opening names alongside Fontaines D.C., IDLES and Gogol Bordello, while leaving individual performance days and headline billing unestablished. This is more detail about an existing booking, not KATSEYE being newly added to the festival. Nor does our verification establish that Sziget has only just assigned the date.⁠66⁠67

Yonhap’s November 11 report explicitly attributes the headliner announcement to HYBE–Geffen Records and says KATSEYE will perform on the festival’s second day. CHOSUNBIZ gives the same agency attribution and August 11 date. The original agency statement was not available for direct inspection, so the distinction between reported billing and independently verified scheduling matters.⁠56⁠57

Sziget’s own lineup data confirms the appearance and Wednesday assignment, but does not identify KATSEYE’s slot as a headline performance. That is a limit on what the festival record establishes, not evidence contradicting the agency-attributed coverage. Equally, the group’s prominent position in an announcement was never sufficient on its own to establish headline status. Nothing here establishes that KATSEYE is the festival’s only headliner.⁠67⁠56⁠57

For a fan making travel decisions, the strongest practical development is the day itself. Sziget runs Tuesday through Saturday, with festivities continuing into Sunday morning, according to its FAQ. That wider window should not be mistaken for KATSEYE’s performance schedule: the group’s listed festival day is Wednesday.⁠32⁠67

The current August 11 listing also includes IDLES, Bicep live, Tove Lo, Rikas and an act displayed as CHRIS STASSY. Those names tell fans who is scheduled for the same day. They do not establish performance order, shared stages or whether any sets will overlap.⁠67

The spelling deserves a small caution rather than a confident correction. CHRIS STASSY is the festival’s display text, while the same artist record links to profiles using Chris Stussy. The record establishes that inconsistency, not which spelling the performer prefers.⁠67

Other first-wave dates are also identifiable: Nothing But Thieves is listed for August 10, while Fontaines D.C. and Lola Young are listed for Saturday, August 14. These are scheduling details for already announced artists, not a second batch of bookings.⁠67

The official roster also settles the earlier counting problem: there are 20 distinct acts, including Lola Young. The 19-name enumeration in 444’s November 10 report was incomplete; Lola Young was included in other same-day coverage and is in the official data. The difference was not evidence of a withdrawal or an empty booking slot.⁠2⁠61⁠67

What the listing still does not supply is a usable concert time. KATSEYE’s performance record explicitly hides times, and its matching start and end timestamps must not be read as a published set time. The available data contains no named stage records either. A day-by-day assignment is useful progress, but it is not a finished programme.⁠67

The advertised options checked on November 11 include a standard five-day pass at €349 plus €23 handling, for a ticket-and-fee total of €372. The 21&Under five-day pass is €279 plus €18 handling, totaling €297. Including those stated fees, the younger ticket costs €75 less.⁠31

Those are festival-pass prices, not the price of a KATSEYE-only ticket. No August 11 single-day price or sale availability was verified in the official material inspected. That does not mean day tickets will never be sold; it means fans cannot yet rely on a verified Wednesday-only purchase option from this evidence.⁠31⁠32

Travel, accommodation and food remain separate expenses. There is also no established cutoff date for the advertised pass prices, so an assumed deadline is no sound basis for rushing a purchase. The sensible distinction is between securing access to the five-day festival at the advertised rate and waiting for an admission option tailored to one day.⁠31

For now, fans have a clear day to keep free, but not every detail needed to turn that date into a narrowly planned trip. August 11 is supported. The exact hours, stage and cost of attending only that day still need answers.
