Thank you to all forecasters who participated, and congratulations to all who earned medals. This tournament was part of Rethink Priorities’ research efforts to better understand the likelihood of nuclear conflict and key factors involved in nuclear conflict that could serve as valuable information for decision-makers. We’d like to thank Rethink Priorities for sponsoring this tournament.

The tournament featured a number of questions related to nuclear proliferation and geopolitical factors, like the questions below:

This tournament has ended, however a number of longer term questions on the topic of nuclear risk remain open for forecasting as part of the Nuclear Risk Horizons Project, also sponsored by Rethink Priorities.

Congratulations again to blednotik, MariaSh, and jowo!
