What are the pro arguments? Isn't this like letting a boxing judge place a bet before they say who won? If it's at all objective it shouldn't be allowed for integrity imo

Creators are allowed to trade on their markets in general, right now.

@jacksonpolack I get that and maybe at launch that was necessary to get people to participate but if anyone is to actually take this as a true market place it has to be at least less corrupt than Wall Street 😆.

Seriously it's all for fun and play money but a rigged game gets old fast.

it is not in practice rigged

It seems to me that doing so has outsized influence on league leaderboards, making "make-and-then-resolve lots of markets" an excessively-dominant strategy for leaderboard-climbing without producing any corresponding value-add to Manifold-as-a-whole. (Given the value-add from the market's existence being covered already by its associated trader bonuses.) So I'm currently against it. (Although open to argument regarding why I'm wrong about this.)

@Tulip I agree that’s part of the problem. To be fair, creating markets is part of what makes Manifold work. But market creators already have bonuses for each trader, and those bonuses provide an incentive that is aligned with the value they provide (creating markets that users want to trade in).

The “bet before resolve” just provides terrible incentives to market resolution in most markets, which have a non-objective aspect.

Does it? I don't think it does in masters, I'm not sure about lower leagues.

I think the problem isn't market creators doing it, it's people trading right before resolution in general.

Help us understand what people think about this.

A bit more context and some arguments here:

I think market creators already have incentives to market creation. Betting on your own market right before resolving introduces a significant conflict of interest for the market creator.

I'm meh on this, don't really care but it's apparently a bit of a contentious issue. Curious to see what people think!
