The 91.5 percent trader consensus against Israel reopening its embassy in Iran in 2026 stems from the complete absence of diplomatic relations since the 1979 Iranian Revolution and the U.S.-Israel military campaign that began with nearly 900 strikes on Iranian targets on February 28, 2026. Recent developments have reinforced this outlook, including repeated violations of fragile ceasefires, continued Israeli airstrikes in Lebanon and against Iranian-linked positions, and President Trump’s May 11 rejection of Tehran’s latest proposal as unacceptable. These factors have left any path to normalization effectively blocked through year-end, with traders pricing in negligible odds absent a fundamental shift in bilateral posture or regime dynamics.
