tartoranA prediction market user made $436k betting on Maduro's downfall
can i bet on when prediction markets will collapse due to rampant insider bets?
How? Then why would non-insiders bet? The classic prediction market is guessing the weight of an elephant (or some animal) at a circus. The average guess of the crowd will actually get very close. But if someone knows the actual weight, no one would play.
The entire idea of a prediction market is to aggregate insider information. If you don't have insiders, you're not doing predictions, you're just doing gambling.
Granted: that's what almost every Polymarket user is actually doing. But that's a bad thing. The insider whales are the only ones actually using it for its intended purpose.
It's not 'predicting' when the outcome/answer is known. From the wiki entry on prediction markets "The main purpose of prediction markets are eliciting aggregating beliefs about an unknown future event."
I think you should probably read more about the background of prediction markets. Robin Hanson is a useful place to start. The whole concept of a prediction market is to convert private information into prices. That only works with "insider" information.
I don't know much, but I can't see why betting on a known outcome is good? Why not just ask the knower? Also, just because Robin Hanson says "it's about aggregating insider information" makes it true. He writes some stuff.....
The idea is that people have all sorts of fragmentary information about future events that they can't directly reveal, due to confidentiality or trade obligations (among other things), and that a prediction market effectively liberates the directional content of that information by converting it into prices.
Robin Hanson can credibly claim to have invented prediction markets as we understand them today.
"that a prediction market effectively liberates the directional content of that information by converting it into prices."
I can see this, and I guess maybe my issue is with the phrasing of "aggregating" insider information. Because you aren't just aggregating insider info, you are also aggregating non-insider information, but no one (but the insider) knows what is right.
Is there different types of prediction markets then? One where there is a true insider and one without? For example, you could take bets on weather it will rain on Saturday. People can make educated guesses, but no one really knows (no insider). On the flip side, Kanye could create a bet on whether he will run for president. He would be the only insider, so again, aggregating insider and non insider information.
I would argue that a "market" in whether it will rain on Saturday isn't really a prediction market, or even a market, at all. It's just a bookmaking operation. The core function of any market, in anything, is price discovery.
What's the difference between a "Monday it will rain" market and a NCAAF prop bet on a team's rushing yards? I could argue that DraftKings prop bets are actually more like prediction markets than these "will it rain" bets. People actually do have directional information to contribute to sports propositions!
(I think online sports betting is evil.)
