Trader consensus on Polymarket assigns low probabilities to major powers joining the Board of Peace by March 31, driven by the absence of formal diplomatic commitments or treaty negotiations from key nations like the US, China, or Russia. Recent developments include exploratory talks at the UN General Assembly in September, where neutral countries such as Switzerland and Norway expressed interest but stopped short of endorsements, amid geopolitical tensions in Ukraine and the Middle East stalling broader participation. No primary announcements have materialized, heightening uncertainty. Traders eye upcoming G20 foreign ministers' meetings in February as a potential catalyst, though historical base rates for new international boards suggest slow adoption without superpower buy-in.
