Welcome to this week's Pokémon news roundup for August 17, 2026. With the highly anticipated 2026 World Championships in San Francisco just around the corner, trainers have a packed schedule of events to tackle. From fresh debuts in Pokémon GO to a challenging Tera Raid in Pokémon Scarlet and Violet, and exciting updates across physical and digital trading card games, here is everything you need to know to stay ahead this week.
Pokémon GO Water Festival and Weekly Events
The Ultra Unlock: Water Festival event kicks off on Tuesday, August 18, and runs through August 24, 2026. This event marks the exciting in-game debuts of Arrokuda and Cramorant. Before that starts, players can jump into Max Monday on August 17 featuring Dynamax Magikarp in One-Star Max Battles. Later in the week, look forward to a Magikarp Spotlight Hour on August 20 and a Starmie Super Mega Raid Day on Saturday, August 22.
Defeat 7-Star Ghost Tera Annihilape
In Pokémon Scarlet and Violet, time is running out to challenge the Level 100 Ghost Tera Type Annihilape. This formidable opponent carries the Mightiest Mark and the Defiant Ability, and the event concludes on August 20, 2026. While you can only catch this special Annihilape once per save file, you can repeatedly complete the 7-star Tera Raid to farm valuable rewards like Ghost Tera Shards, Exp. Candy, and Protein.
Digital and Physical TCG Updates
Pokémon TCG Pocket is currently hosting the Pachirisu and Beldum Wonder Pick Event until August 25, 2026. Players can obtain exclusive Promo-B series cards, including Pachirisu and Beldum featuring a special Chansey promo stamp. These can be pulled via random Bonus Picks, Chansey Picks, or by completing event missions. For physical collectors, the First Partner Illustration Collection Series 3 is now available, and the Mega Evolution Ascended Heroes Tin will drop on August 28, featuring Mega Meganium ex, Mega Emboar ex, or Mega Feraligatr ex.
Road to the 2026 World Championships
The 2026 World Championships and PokémonXP convention will take over the Moscone Center in San Francisco from August 28 to August 30. To celebrate, the San Francisco Giants are hosting a Pokémon Worlds Night at Oracle Park on August 27, featuring a custom drone show and exclusive Pokémon GO experiences, including special Raid Battles for a Location Background Pikachu. Additionally, PSA will offer exclusive, shifting Mega Charizard X and Y magazine covers at their event booth.
To make the most of this week, boot up Scarlet or Violet immediately to defeat Annihilape before August 20. Remember to check your TCG Pocket app every few hours for the Chansey Pick to secure Pachirisu and Beldum. Finally, stock up on Poké Balls and Raid Passes for the Pokémon GO Water Festival, and prepare your viewing schedule for the World Championships starting August 28.
