MONSTA X "THE X : NEXUS" Concert: Dates, Tickets & Venue (Seoul)

A Seoul arena built for this

“THE X : NEXUS” brings Monsta X back to a stage they know. KSPO Dome sits inside Olympic Park in Songpa-gu. It opened as the gymnastics arena for the 1988 Seoul Olympics, and after its renovation it became one of the city’s main concert halls. It is a round bowl of tiered seating with a low domed roof, and most Seoul K-pop tours of this size play here.

The concert is a stop on the group’s 2026 tour. For many Monbebe, the fandom name, a Seoul show is the one that counts. Monsta X debuted under Starship Entertainment in 2015 after the survival show No.Mercy. A hometown arena date is where the group’s history and its newest material share one setlist.

Date, seats and the ticket picture

The concert takes place at KSPO Dome in 2026. The tour’s official announcements give the exact performance days and doors times, and this guide does not repeat them. No ticket prices appear here either: the official ticketing page lists every seat category with its current price.

Seoul K-pop concerts usually follow a familiar pattern:

• Fan club presale first, then a general sale for remaining seats
• Standing floor plus tiered seats, with the floor split into numbered blocks
• Entry order printed on standing tickets, so a low number means a spot nearer the stage
• Separate international allocations on some tours, sold through an English-language ticket page

Because the dome is a circle, the upper tiers stay fairly close to the stage. Seats at the sides often get a clearer view of the main stage than the far back of the floor.

Reaching KSPO Dome by subway

Driving is the slow option. On show days the roads around Olympic Park back up and parking fills fast. Nearly everyone comes by subway.

• Olympic Park Station (Line 5), Exit 3: the closest exit, a short walk to the dome’s plaza
• Mongchontoseong Station (Line 8): a walk through the park, often quieter after the show
• Hanseong Baekje Station (Line 9): on the park’s western edge, good if you are coming from Gangnam

After the encore, the Line 5 platforms at Olympic Park get very crowded. Fans staying in Jamsil or Gangnam often walk to Mongchontoseong or Hanseong Baekje to skip the crush. The walk takes around 15 minutes through the park.

Lightsticks, IDs and the merch line

Show day starts well before the music. The official merch booth is set up on the plaza outside the arena. Fans typically queue there for hours, and popular items run out. Many attendees head straight for the line and fit everything else around it.

Here is what Seoul concertgoers usually bring and do:

• Photo ID matching the ticket name. Staff at Korean arenas often check names, and an international visitor’s ID is a passport.
• The official Monsta X lightstick, paired by Bluetooth to the venue system. The whole dome then changes colour together.
• Fan chants learned in advance. Monbebe call out member names during intros, and the official chant guides go round fan communities before every tour.
• Phones away during the show. Filming is normally prohibited, and staff walk the aisles to enforce it.

Outside the arena, fans swap freebies: photocards, stickers and small printed goods handed out for free. Bringing a few to trade is the usual way to join in. Card and mobile payment work at the booth and at nearby convenience stores.

Olympic Park before and after the show

The concert sits inside one of Seoul’s largest green spaces, so there is plenty to do around it. The World Peace Gate near Olympic Park Station is the park’s best-known landmark and a popular meeting point. Further in, the grassy earthen walls of Mongchontoseong, a Baekje-era fortress, rise above walking paths and the “Lonely Tree” on its knoll.

For food, Bangi-dong’s restaurant alleys sit one stop away on Line 5 at Bangi Station. Their grill houses and pubs stay busy late. Jamsil is a short ride south, with Lotte World Tower and the lakeside paths of Seokchon Lake. Many fans visiting from abroad book hotels there for an easy trip home after the show.

The SOMA Museum of Art and the park’s sculpture garden fill a slow morning before the merch queue begins. A full day usually runs from the plaza around midday to the last trains after the encore.
