Trainers, a perfect storm is here. Now is the time to claim your final reward for achieving Spark’s Challenge during Chicago Go-Fest! Raikou Raid Day is upon us, and many trainers are rising to the challenge. The Thunder Pokémon Raikou will be available to challenge in raids for three hours from 4 PM- 7PM local time on June 29th. Lucky Trainers may even encounter a Shiny Raikou. The Silph Research Group is recording data to deduce the probability of encountering one of these orange and gold embodiments of the speed of lightning! Enjoy!

Raid days are over! Researchers collected data on 1937 Raikou, and were able to encounter 183 shinies in those total raids. Using these numbers we are able to determine that Raikou has a shiny rate of approximately:
1 in 10 (99% CI of 1 in 9 – 1 in 13)
These data lead us to conclude that the same shiny rate used for past Raid Days is in effect. Thanks for stopping by, and see you next time!
