Any situation where you can make bets on the market that pay off larger than the cost of the market it will lead to manipulation. This is no different than paying off the referee or the star players etc ... The only thing keeping this from happening is the threat of the law really or any adversarial change in incentives. But once a player or collective of players gets big enough, it seems likely this is happening even if it is not coordinated centrally.
It would be interesting if more people started to get interested in this problem.
I have seen defi stuff that literally bakes in the cost of moving price into the smart contract "market" which is interesting too but at the time of reading (a few years ago) I didn't see direct discussion of the boundaries of manipulation incentives in that domain. Would be interested to hear if anyone is deep in that rabbit hole recently.
