U.S. x Russia nuclear arms control deal confirmed by...?

This set of markets tracks whether the United States and the Russian Federation reach an official agreement on nuclear arms control or strategic nuclear weapons limitation, across multiple deadlines. Each market resolves to "Yes" if a qualifying agreement is publicly announced as concluded and acknowledged by both governments on or before its deadline. The markets resolve independently: an agreement reached before an earlier deadline also resolves all later-deadline markets to "Yes". See individual market rules for full resolution criteria.
