If 50% or more of bettors bet Yes, then the market will resolve Yes. Otherwise, it will resolve No.

If everyone picks one side and sticks to it, everyone wins. If there is any divide at all, someone will lose money

This is somewhat related to the Red button / Blue button debate.

The amounts individuals bet do not matter

If there are 13 bettors, then 50% would be 6.5 bettors. If there are 6 bettors on Yes, the market would resolve No since 6 is less than 6.5. if there were 7 bettors, it would resolve Yes since 7 is more than 6.5

If there is an equal split of bettors on both sides (if the number of bettors on both sides are equal), then the market resolves N/A

No coinflip will be used to decide the tie-breaker since the point of this market is to see how well people can work together
