Reza Pahlavi remains in exile without institutional ties to Iran's Supreme Leader, Guardian Council, or elected presidency, while the Islamic Republic's constitutional framework channels leadership transitions through domestic clerical and military structures. Ongoing domestic protests, opposition fragmentation, and external sanctions have produced no verifiable momentum or procedural openings for his assumption of power by the end of 2026. Trader consensus at 98.8% on "No" reflects these structural barriers and the absence of recent diplomatic or internal developments that would reposition him as a viable successor. Late regime instability, coordinated opposition breakthroughs, or unforeseen succession crises could still shift outcomes, though such scenarios lack current evidence.
