The International Mathematical Olympiad (IMO) is an annually held high school mathematics competition. This year the contest is held in Japan. Will any contestant obtain a perfect score of 42 points?

Resolves according to the statistics that will appear shortly after the closing ceremony (12th of July) here: https://www.imo-official.org/year_info.aspx?year=2023. Trading closes when the closing ceremony starts.

For comparison and clarity, in 2022 there were 10 contestants who got full scores (see here) and the market would have resolved YES.

I thought that the results would appear only after the closing ceremony, but they are already up (https://www.imo-official.org/year_info.aspx?year=2023). Hence I've resolved the market.

Now that it's over, was @PC being overconfident or did he have a reason to buy that much?

bought Ṁ0 of YES

@jacksonpolack I was obviously betting on the brilliance of our next generation :) Feels like a decent way to lose money

haha - happy to share, but maybe it would be more fun in some market form :P

@PC Connected with @jacksonpolack , and wanted to share with everyone that I was making informed bets.

When I bid up to 97% on Sunday night (which is after the test was done but before any tests were marked), I was 99.5%+ sure that there was at least one perfect score. So, there was a chance that I was wrong, but I was pretty confident at that point. Apologies if people bet and lost money because they thought I was just gambling

bought Ṁ100 of NO

i'm currently in japan, do with that information what you will (many of my manifold followers can confirm this to be true)

bought Ṁ0 of YES

@Devansh LOL and yet you have put less than 1k in, where is your conviction?

my sense is PC has inside information / strong non-inside information so i'm not betting no. we'll see

bought Ṁ38 of YES

@jacksonpolack LOL if I had inside information I would be making money in other IMO markets

Interesting

bought Ṁ0 of YES

Why the vast overconfidence here? Out of the previous 20 IMO's, there have been 3 where nobody got a perfect score. That should put the base rate for this question at 85%

predicted NO

@sbares Well, I suppose if someone here participated and is quite confident in their performance...

bought Ṁ400 of YES

@sbares so little faith in our high schoolers and their increasing intelligence :P
