Gotcha risk — resolution-rule assessment

Show full assessmentShow less

This market resolves based on whether conclusive proof is published before the specified deadline, defaulting to a negative outcome otherwise. The primary risk stems from the lack of a named official scientific body or specific evidentiary standard, relying instead on decider judgment regarding what constitutes conclusive proof and what qualifies as a consensus of credible reporting. While the deadline is clear and the default outcome is standard, the criteria for acceptable proof remain subjective.
