I've been keeping an eye on them ever since tha Augur days which I believe is the original one (it never went anywhere from what I can tell). For me, these 'prediction markets' always felt more like a gimmick as a way to mainly bet and get exposure on elections with size and as a way to check proper estimations on certain outcomes.

I guess polymarket has won this race but I don't think they have a token yet. I've always wanted to actually test it out but I never got that far. Unless one of these prediction markets present themselves like a normal bookie/exchange with solid odds, I don't think it will ever be something that I would use. I might give it a go and test some out though. I know that Winr is also planning to explore prediction markets.
