The Pokémon GO May 2026 Raid Bosses rotation is one of the busiest the game has seen in quite some time, with multiple major Legendary Pokémon returning, new Mega content arriving, and players already preparing for Pokémon GO Fest 2026 Global later this season.
Between powerful raid attackers like Groudon and Kyogre returning to the spotlight, Shadow Landorus appearing through Team GO Rocket content, and Mega Evolutions continuing to dominate raid teams, May is shaping up to be a huge month for players focused on building stronger Pokémon.
If you are trying to work out which raids are worth prioritising in Pokémon GO during May 2026, here is the full breakdown of the current Pokémon GO May 2026 Raid Bosses, raid hours, shiny availability, and best raids worth spending passes on.
Current Pokémon GO May 2026 Raid Bosses – Five-Star Raids
Five-Star Raids continue to be the main attraction in Pokémon GO, especially with several meta-relevant Legendary Pokémon rotating throughout the month.
Current and Expected Five-Star Raid Bosses
Nihilego has already returned during early May rotations, while Groudon and Kyogre continue generating huge interest due to both Primal forms remaining among the strongest Pokémon in the entire game.
If you are planning raid teams this month, our full Groudon Pokémon GO raid guide and Kyogre Pokémon GO raid guide both cover the best counters, weaknesses, and whether they are still worth powering up in 2026.
Current Mega Raids in Pokémon GO
Mega Raids remain one of the best ways to collect powerful Mega Energy while also building teams for future raid content.
Current Mega Raid Bosses
- Mega Camerupt
- Rotating Mega Evolutions throughout May
Mega Camerupt is particularly interesting because of its Ground and Fire typing, giving players another option ahead of future Steel and Psychic-heavy raid content later this year.
Many trainers are also expecting Mega raid rotations to ramp up heavily as Pokémon GO Fest 2026 Global approaches, especially following the official reveal of Mega Mewtwo X and Mega Mewtwo Y.
Current Shadow Raids in Pokémon GO
Shadow Raids continue to be one of the most rewarding parts of Pokémon GO for players looking to build top-tier raid attackers.
Current Shadow Raid Highlights
- Shadow Landorus through Giovanni
- Weekend Shadow Raid rotations
- Rotating Shadow Legendary encounters
Shadow Pokémon receive a 20% damage boost compared to normal Pokémon, which is why many high-level players prioritise them so heavily for raid content.
Shadow Landorus in particular is becoming one of the strongest Ground-type attackers in the game.
If you are still trying to defeat Giovanni this month, our Pokémon GO Giovanni May 2026 guide covers the full lineup, weaknesses, and best counters.
Pokémon GO Raid Hours May 2026
Raid Hours continue taking place weekly in Pokémon GO and remain one of the best opportunities for farming:
- Legendary Candy
- XL Candy
- Shiny encounters
- High IV Pokémon
Raid Hour Time
- Wednesdays
- 6:00 PM to 7:00 PM local time
During Raid Hour events, nearly every gym becomes occupied by the featured Legendary Pokémon.
This is usually the easiest time to complete large numbers of raids quickly, especially in populated areas.
Best Raid Bosses Worth Doing in May 2026
Not every raid boss is worth spending Premium Battle Passes or Remote Raid Passes on.
Highest Priority Raid Bosses
Groudon
Still one of the strongest Ground-type Pokémon in the game.
Kyogre
Arguably the best Water-type attacker in Pokémon GO.
Shadow Landorus
One of the strongest Shadow Ground attackers available.
Mega Evolutions
Always worth farming if you still need Mega Energy.
The value of Ground and Water-type attackers may become even more important very soon as Pokémon GO Fest 2026 Global gets closer and Mega Mewtwo X and Mega Mewtwo Y prepare to enter Super Mega Raids for the first time.
Can Current Raid Bosses Be Shiny?
Most major Legendary raid bosses currently available in Pokémon GO can be shiny.
Current Shiny Raid Targets
- Groudon
- Kyogre
- Nihilego
- Various Mega Raid Pokémon
Legendary raid shiny rates are typically estimated around:
- 1 in 20
That makes Raid Hours especially valuable for players chasing shiny Legendaries.
Best Pokémon To Use in Raids Right Now
If you are trying to build strong raid teams with Pokémon GO May 2026 Raid Bosses, several Pokémon continue dominating overall performance charts.
Best Current Raid Attackers
- Primal Groudon
- Primal Kyogre
- Mega Rayquaza
- Kartana
- Shadow Mamoswine
- Mega Sceptile
- Shadow Metagross
Kartana remains particularly absurd thanks to its incredible Attack stat, while Shadow Mamoswine continues dominating Ice-type raid damage output.
Are Remote Raids Still Worth It – Pokémon GO May 2026 Raid Bosses?
Remote Raiding is still extremely useful, although many players now save Remote Raid Passes for:
- Exclusive Legendaries
- Shiny hunting
- Raid Hour farming
- Global event rotations
With GO Fest approaching, many trainers are already stockpiling raid passes in preparation for some of the biggest raid rotations Pokémon GO has ever seen.
What Raids Should Players Prepare For Next?
While current Pokémon GO May 2026 Raid Bosses are already strong, many players are looking ahead toward:
- Pokémon GO Fest 2026
- Mega Mewtwo X
- Mega Mewtwo Y
- Potential Ultra Beast returns
- Future Shadow Legendary rotations
Mega Mewtwo alone is expected to massively impact the raid meta due to its unbelievable stats and expected damage output.
That is one of the biggest reasons players are heavily investing into strong Ground, Dark, Ghost, and Bug-type attackers right now.
Why May 2026 Is a Huge Month for Pokémon GO Raids
The Pokémon GO May 2026 Raid Bosses lineup feels important because it is clearly setting the stage for larger content later in the season.
Between:
- Powerful Legendary returns
- Strong Mega Evolutions
- Shadow Legendary battles
- GO Fest preparation
- Mega Mewtwo hype
There is a genuine reason for players to actively build raid teams again.
For many trainers, May 2026 is less about single raid bosses and more about preparing for what could become one of the biggest Pokémon GO summers in years. Be sure to check our Pokémon Go Hub for more event and raid details as they happen.
