The timing on this is ridiculous - my first ever larger size polymarket bet, and that just so happens to be seconds before someone comes in with almost $1M to shift that market 4% in the other direction, in an (unsuccessful) attempt to win a secondary market… https://x.com/jon_charb/status/1832112496968171679

Polymarket should ban self-referential markets > creates too much upside for manipulators.

Not sure I agree actually! These types of temporary market inefficiencies just provide incentives for actors to come in and bring them back to the true equilibrium. E.g. in my case I bought some more (cheaper) shares once I noticed the drop. Given that my underlying conviction didn't change, that was free money.

In general my guiding principle in these questions is "don't solve via rule enforcement what can be solved via markets", even if those markets sometimes need some time to mature and become efficient.

Right, but take the extreme case: “Trump <50% to win as of midnight, start of (date)”. This market is manipulable with a single large order in the last polygon block of the day. Polymarket can’t stop another exchange from making this dumb market, but no reason to feed it their own distribution.
