Thailand is gearing up for one of its grandest year-end celebrations as ICONSIAM reveals its lineup for the Amazing Thailand Countdown 2026 — a five-day celebration filled with world-class performances, cultural tributes, and a landmark New Year’s Eve show along the Chao Phraya River.

This year’s program features a 4D sky performance, environmentally friendly fireworks, and a breathtaking fusion of drones and pyrotechnic displays, staged in remembrance of Her Majesty Queen Sirikit, The Queen Mother, honoring her enduring grace and influence.

A major highlight is a world-class performance from Mark Tuan, headlining an exclusive countdown performance made specially for ICONSIAM. The GOT7 star will also be taking the stage with an iconic line-up of Thai artists as a gift to all attendees.

Across five days from Dec. 27 to 31, over 200 performances will come together to create a one-of-a-kind experience on the global countdown stage. The lineup of artists was built around five joyful musical rhythms:

• POP POWER (Dec. 27): PiXXiE, 4EVE, ATLAS, DMD BOYS, and XEBIS ENTERTAINMENT kick off the party with upbeat, feel-good sets
• DANCE FORCE (Dec. 28): URBOYTJ, CDGUNTEE & NARA, CIR*CL, THE 52 ARENA, and Paul Sirisant turn ICONSIAM into a high-energy party
• ROCK INFINITY (Dec. 29): Slot Machine, Three Man Down, Y2Z, artists from IAM, and artists from WAYDAY deliver an emotional, guitar-driven night
• GLOBAL PHENOMENON STAGE (Dec. 31): Mark Tuan, Jeff Satur, Bodyslam, BUS (Because of You I Shine), PROXIE, DEXX, Zee-Nunew, and Tie-FirstOne headline the final lineup to 2026!

Visitors can join in the countdown celebrations through several access routes, such as social media activities, walk-in entry, ONESIAM memberships, shopping privileges, and special fan programs (T&C applies).

Get ready for the grandest year-end celebration bringing together the public, private sector, community, and international partners for one of the country’s most anticipated celebrations.
