A version of that probably happened last night with Lk-99, the “Iris” replication claim. Why do think it’s such a problem? Those are the risks of speculating and the market adjusted back downwards in very short order. If Iris was a manipulator the gains were minimal and fleeting. The anti-markets comments all over this are so unfortunate and misguided. By your own logic don’t you just prove that a real lab is now pot…
The base prior (the market price) is that this will not replicate. This scenario is a way to make a quick buck claiming the opposite without doing any actual hard work. In regular markets you can't just say "we increased our sales 1000%" and a week later "oops, sorry, misplaced decimal dot". You can do that in prediction markets.
I don’t understand what you think is different with other markets. Information must be assessed for it’s accuracy and acted on by participants.
In this case I’d even argue the prediction market helped focus attention and resulted in rapid counter analysis that questioned the claims.
Perhaps without the LK-99 markets effects the false information would have had wider and longer reach? The losses of the unskilled participants are a perfectly acceptable cost and in fact beneficial in the long term.
