I was wondering if anyone know how many levels your trainer can become in Pokermon Go?
According to this article the maximum Level is 40. They found the information with datamining, there is no official statement about this.
You need 5 million experience points to reach from level 39 to 40.
Afaik at the moment (20.07) the highest level players reached is level 30 and they need 500k xp for level 31
