My bad JJG, I meant 2027 (edited the OP).
then that certainty level of the claim could make it more bettable - including taking sides and potentially figuring out odds
The bet is set up by negotiating the rates (and therefore the ticket amount) between the two sides - they need not be equal in the general case (40/60 easy to do etc). Winner takes all.
Even if we correct the date to your original intention, I have difficulties finding it sufficiently controversial in order to be bettable, and yeah, maybe someone would be willing to take one side or the other of the bet.
Let me see if I understand the bet. You are saying that the price would have to be $200k or greater on January 1, 2027? How is that different than proposing whether it would be over or under?
To me, it does not really seem any different than WatChe's original proposal, except for specifying the date to be January 1, 2027 rather than being January 2027.
