A limited Pokémon card was supposed to be a cheerful anniversary perk. Instead, it became a crowd-control problem in Seoul.
Pokémon Korea canceled an on-site giveaway at Pokémon Mega Festa 2026 on May 1 after an estimated 40,000 people gathered around Seoul Forest by midday, according to The Korea Times. The rush centered on a Korean-exclusive Magikarp promo card, available to fans who completed a Pokémon GO Stamp Rally during the event.
Why the crowd formed
Pokémon Mega Festa 2026 is part of Pokémon Korea’s month-long celebration tied to the franchise’s 30th anniversary. The event is being held around Seongsu-dong and Seoul Forest, alongside the Seoul International Garden Show.
One of the main draws was the Pokémon GO Stamp Rally. Fans who collected three stamps at designated locations were set to receive event items, including a rare Magikarp promo card exclusive to Korea.
That combination proved volatile: a public holiday, a limited physical collectible, and a card with immediate resale value. The Korea Times reported that the Magikarp card had already appeared on resale platform Kream for 286,000 won, about $194.
