https://tontine.cash/ is a MSCHF game. On 2021-12-27, 7141 players each paid $10 into a central pot and have been required to check in at least once a day by midnight EST/EDT or else be eliminated. The last remaining player will win the pot. As of 2024-6-5, 250 players remain.

Each choice in this market resolves YES if the living count is 223 (1/32, 5 half-lives) or less as of 12:05 AM EST on its labelled date, and NO if the living count is 224 or more at that time. It resolves early to YES if the living population should fall to or below 223 before that time, and to N/A if the game is canceled for any reason. I reserve the right to extend the closing time and add new choices if I judge it necessary.
