This market helps us assess
1. Ambiguity in the question statement and descriptions of the major markets.
2. Unexpected scenarios that makes a clear resolve difficult.
3. Probability of event not happening in conditional markets

(In short, this market helps us assess the probability of a market resolving NA or any percentage other than 100%)

To give a few examples:
Will AI be a major topic during the 2024 presidential debates in the United States? (could resolve NA if whether AI is a major topic ends up being debatable, despite the clearly listed criteria by Matthew Barnett)
By end of 2028, will AI be considered a bigger x risk than climate change by the general US population? (could resolve NA or 50% if undecided)
Will GPT-5 be released before 2025? (ambiguity if GPT released a new version but changed its name)
Will the Meissner effect be confirmed near room temperature in copper-substituted lead apatite? (resolution unclear if the scientific strong but not overwhelming)



Each individual listed market resolves YES if the corresponding major market resolves YES.
Each individual listed market resolves NO if the corresponding major market resolves NO, NA or any percent less than 100%.
