Will any binary market reach NaN%?

Although /cloudprism/will-any-market-reach-nan resolved YES, we still have not learned whether it is actually possible to bet so much on a market that the probability displays as NaN%, since that market resolved due to a deprecated market type displaying "Resolved NaN", which is a distinct glitch.

The glitch I'm talking about is this one:

This market will resolve YES if the probability of any market of the "Yes / No" market type displays as NaN% as a result of the glitch above (a large amount of mana being bet on one option and somehow destroying the probability calculation), and I receive evidence of this before close. Other glitches that cause it to display NaN% will not count.

Clarifications:

  • If this has already happened, I will count it as a YES if I find out about it before close.

  • All binary markets count for this, including delisted or private ones, but I have to receive proof that they really do say NaN% before close.

  • It still counts even if the probability only says NaN (rather than NaN%) or some equivalent. If it displays a non-numerical probability like "Error%" or just "%", I will also count it as long as it's clear that it was caused by the glitch in the image above.

  • In reference to the point above: If there is significant doubt as to whether it is caused by the glitch above, I may resolve to a probability or N/A.

  • It must display on the main page for the market itself to qualify for a YES resolution. However, I will resolve to 50% if a market's probability is displayed as NaN% in search or embeddings, but not on its main page.

  • This is about whether the actual probability is displayed as NaN%, not whether the betting interface says that it hypothetically would be NaN% if you bet enough. The latter is already the case, since that's the glitch in question.

https://manifold.markets/Joshua/will-kevin-mccarthy-get-into-a-phys said "Trade too large for current liquidity pool", so highly likely this will be NO.

predicted NO

@AnT Well, that actually answers the question I created this market to answer. I wanted to know if it was even possible to trade that much and if so what percentage would be displayed.

predicted YES

not quite a match, since it's from one of the new unlinked free responses and was due to resolution not betting, but I've seen some of these:

predicted NO

@Stralor I think this happens for all multiple choice markets. It wouldn't count even if it was a binary market, though, since it doesn't actually display that probability anywhere on the market's page.

But someone has to actually do it for this market to resolve yes, right?

And it has now closed.

predicted NO

@JohnSmithcf7b Did anyone actually bet 6358 mana and cause it to display NaN%?

predicted YES

.

predicted NO

@JohnSmithcf7b Then it does not resolve YES.

predicted NO

@JohnSmithcf7b The question is about whether a market will actually display a nan as the probability, not whether the betting interface will display it as a hypothetical probability. We already know that the betting interface can do that - if we didn't, then the picture in the description wouldn't exist.

It seems that the bug has been fixed. I am no longer seeing new prob NaN% on any market when I bet max yes.

bought แน€20 of NO

@ShadowyZephyr I'll still leave it open, since the bug could resurface, but this is looking like an even safer NO bet now.

predicted NO

The old market was at 1%, what gives?

Is a single answer on a multi-binary market considered a binary market?

predicted NO

@Mira I assume not

predicted NO
