Recent diplomatic momentum between Washington and Tehran, mediated by Qatar, has led President Trump to signal that major U.S. combat operations against Iran are unnecessary for now, following Republican midterm losses tied to the conflict's economic costs. Trump has described the war as "effectively" ending and cited appeals from Gulf states to maintain the status quo of limited strikes and a naval blockade rather than escalation. Iranian officials continue to insist on preconditions including sanctions relief and an end to the blockade before broader talks, while both sides reject full-scale ground operations. With no verified plans for an invasion and traders viewing the current trajectory as one of stalemate or negotiated de-escalation before year-end, the implied probability of "No" reflects consensus that a large-scale U.S. ground campaign remains unlikely in the brief window before 2027.
