Signs of an extraordinary mega-powered week are beginning to appear.

Mega Ascension runs from Monday, August 31 at 10:00 a.m. to Friday, September 4, 2026, at 11:59 p.m. local time — the lead-up to Pokémon GO Fest 2026: Mega Finale. Prepare with a week of Mega Raids, Kalos first partner Pokémon, and GO Pass: Mega Finale.

Pokémon caught from Mega Raids during Mega Ascension may have a Mega Evolution–themed Special Background. Starting during this event, when a Pokémon with that background Mega Evolves, its background gains additional effects for the duration of the Mega Evolution.

Daily Discoveries, Seasonal Mega Raids, Seasonal Five-Star Raids, Seasonal Shadow Raids, Seasonal Raid Hours and Seasonal Spotlight Hours will not take place during Mega Ascension and Pokémon GO Fest 2026: Mega Finale. Mega Ascension and Mega Finale Raids take their place from Monday, August 31 at 12:01 a.m. to Sunday, September 6, 2026, at 11:59 p.m. local time.
