Any contiguous 1 hour period before close where this market does not drop below 90% causes this to resolve YES. Otherwise it resolves NO.
Goes by the probability displayed on the graph, so 89.5% rounds up to 90%.
Similar, but with longer timeframe: https://manifold.markets/BenjaminIkuta/will-this-market-stay-at-or-above-9?r=QmVuamFtaW5Ja3V0YQ
@AllanLacy Technically Isaac didn't say it would resolve at market close. If the whale comes in 1 minute before end, and Isaac doesn't resolve until 2 hours later, then it would resolve yes
@NicoDelon Yes; hence the question. I have a good prediction of the joke now, though, if you don't want to explain.
I'm not sure why some people are still buying YES within 1 hour of close. The description says "Goes by the probability displayed on the graph", and the graph stops updating at close. Doesn't that imply that if it gets bet up to 90% at the last second, and Isaac waits (e.g.) 2 hours before resolving, it would still have to resolve NO?
