This market focuses on the increase in the world population, defined as the total number of humans alive. The resolution date will shift based on market odds: it will move closer as the odds increase and further away as the odds decrease. Initially, with 50% odds, the resolution date is set 50 years in the future. If the odds rise to 60%, the resolution date changes to 40 years in the future. Conversely, if the odds drop to 40%, the resolution date moves to 60 years in the future. Each 1% change in odds adjusts the resolution date accordingly by one year. The market will resolve to YES when it trades at 99% and the resolution date one year ahead is reached. It will resolve to NO when it trades at 1% and the resolution date 98 years ahead is reached.
