What are the chances of finding a Gigantamax Den?

Question

I found a random Gmax Snorlax Den in the Crown Tundra and now I'm curious.

Asking for offline play.

Answer 1

Without increasing odds for Wild Area News events, the odds are 5% per Gigantamax form for each specific raid den it can be in. Each form has one den in the Wild Area, IOA, and CT.

So the odds of finding one in a form's specific Gigantamax Den are 5%.
