Resolution criteria
This market will resolve to "Yes" if the S&P 500 Index's closing value on Oct 31, 2025, is within 1% of its all-time high.
If the market reaches a new all time high, that will be what the market must be within 1% of for the market to resolve to "Yes." If the closing value falls outside this range, the market will resolve to "No.". If the market closes exactly 1% below all time high this will resolve to 50%
Update 2025-10-13 (PST) (AI summary of creator comment): "Within 1%" means: closing value > 0.99 × all-time high
(Not: 1.01 × closing value > all-time high)
@Magnify does "within 1%" mean:
A: close > 0.99*ATH, or
B: 1.01*close > ATH
it's less than a point of difference, but worth clarifying just in case. thanks!
if it's exactly at 1% [edit: I see this was in description]
