Many trainers have been eager to try out Raid Battles, a new co-op feature in Pokemon GO. Today, the bar has been lowered even further – if you’re at least level 20 in Pokemon GO, you can now participate in Raid Battles.
Trainers level 20 and above: You can now participate in Raid Battles at a wide variety of Gyms around the world.

At this rate, everyone should be able to participate in Raid Battles by the end of the month. So if you’re below level 20, hang in there for a few more days!
