If an intelligence explosion occurs, this market resolves N/A. Otherwise:
Shortly after market close, I will post a Yes/No poll in this market's comments, in the Manifold discord, and/or in whatever other appropriate Manifold-related spaces exist at that time. It will ask:
Do you believe that a rapid AI intelligence explosion poses a significant existential risk to humanity before 2075?
This market resolves to the percentage of Yes votes in the poll, rounded to the nearest integer.
The poll will be limited to one response per Manifold account, and the way everyone voted will be public.
All markets for each year:
Theoretically, all these markets ought to predict the same probability if people's beliefs are rational, right?
Any difference would imply that the markets predict that the polls will make exploitable under or over confident predictions, which would be rather interesting.
(They might trade at slightly different prices due to discounting, but I don't think that should make a huge difference.)
Technically you could have someone who believes it's not a concern up until 2073, but is a concern in 2074, so they'd rationally answer no on next year's poll and yes on the year after that.
But realistically, yes, I created these markets to see if people's updates are predictable.
They're also implicitly forecasting what clusters of people end up becoming Manifold users. If at some point Manifold suddenly catches on in the AI-capabilities research community, the next year's poll may skew downwards, even if no individual person ever changed their mind.
Good points, the questions are asking about different end dates. The experiment would probably work better if they all asked about intelligence explosion before 2100, for example. And yeah, changes to the poll respondents are likely an important consideration.
Metaculus has noticed this possibility as well and there's some discussions on it here:

Ok, both changes made. If anyone had placed a bet based upon the earlier descriptions, let me know and I'll reimburse you.
