In the mobile game Pokémon GO, a ‘Mega Ascension’ event was held from August 31 to September 4, 2026. This event featured the return of Mega Evolution Pokémon, such as Mega Victreebel, Mega Dragonite, and Mega Liepard, appearing in standard 4-star Mega Raids. Expanding into the trading card game, The Pokémon Company announced the ‘Mega Evolution – Delta Domain’ expansion for a global release on November 6, 2026. The set includes the return of Mega Rayquaza-ex alongside new cards like Mega Golurk-ex, Mega Malamar-ex, and Mega Golisopod-ex. The expansion also introduces ‘Legendary Stadium’ cards, which are pairs of cards that form a single, larger illustration when played together. Recent market activity surrounding the 30th Anniversary expansion and the upcoming Delta Domain set has caused significant disruption. In the United States, retail environments have faced intense competition for stock, resulting in long queues and physical altercations. Notably, police intervened at a Target in Connecticut after a fight involving a reseller resulted in an injury to a child. Conversely, the secondary market has seen a shift in dynamics. Due to increased product availability and higher pull rates for rare cards, resale prices for most high-end cards have remained below 200 euros, which is significantly lower than previous sets. While specific Mew-themed cards still command prices in the thousands of dollars, the current trend appears to favor collectors by making rare cards more accessible and reducing profit margins for resellers. ## Timeline ### 2026-09-22: Pokémon TCG 30th Anniversary expansion disrupts retail and resale markets The Pokémon TCG 30th Anniversary expansion is causing retail chaos and physical altercations in the US, while simultaneously undermining scalpers through higher card availability and better pull rates. 10 sources. https://clstr.news/cluster/the-pokmon-company-announces-mega-evolution-delta-domain-expansion ### 2026-08-31: Pokémon GO hosts Mega Ascension event with returning Mega Evolution Pokémon Pokémon GO is holding a ‘Mega Ascension’ event from August 31 to September 4, featuring Mega Victreebel, Mega Dragonite, and Mega Liepard in standard 4-star Mega Raids. 7 sources. https://clstr.news/cluster/pokmon-go-hosts-mega-ascension-event-with-returning-mega-evolution-pokmon --- Cite as: Pokémon Mega Evolution and TCG market developments.
