I can't stand people posting this website on HN. Polymarket is a bunch of gambling addicts just throwing money at a wall - there's no market research or actual backing insight. It has such intellectual rhetoric as:
> if you look closely, you can see DUMFUQ Sucks-His-Balls BUYING HIGH, then SELLING LOW! Dumfuq SUCKS-HIS-BALLS must have confused this for a Ceasefire market to trade like shit!
I think you've shown Polymarket comments are crap. But I'd say that for every venue on the internet except, occasionally, HN.
While there is legitimate concern around manipulation given Polymarket's thin volumes [1], there is limited evidence that the broader value of prediction markets applies to them [2]. (I started taking it seriously after Nate Silver hitched up his wagon [3].)
I'm sceptical of political predictions. I have limited respect for crypto. But on the balance, once you account for manipulation risk, it has a good track record. More pointedly to OP's question, I don't see any controversy around its adjudication and ability to pay.
That's how the stock market works as well. The only people with actually valuable information are a very tiny fraction of the participants. And that's fine. Wisdom of crowds will still prevail.
Polymarket is, at least for tariffs [1].
