Ceasefire expectations between the U.S. and Iran have increased significantly, according to BlockBeats. PolyBeats monitoring indicates that the probability of a ceasefire by the end of April has risen from 18% to 28%, by the end of May from 34% to 42%, and by the end of June to 53%. This surge in expectations is largely driven by U.S. President Donald Trump's ultimatum for peace talks with Iran, which has set a deadline for negotiations by Tuesday 8 p.m. Eastern Time (Wednesday 8 a.m. UTC+8). Additionally, various reports have bolstered ceasefire prospects, with sources revealing that the U.S., Iran, and regional mediators are discussing a potential 45-day ceasefire agreement that could lead to a permanent end to the conflict. Iran and Oman also held talks on Saturday to explore options for ensuring safe passage through the Strait of Hormuz.
