Iran leadership change by 2026?

Platform comparison

Market context

Mojtaba Khamenei stops being the effective decision-maker in Tehran only if he is formally removed, detained, or otherwise prevented from acting, so the key variable is not rhetoric but an observable transfer or interruption of authority. The current 11% implied probability is modest, but it is not detached from the wider market picture: prediction-market pricing elsewhere has treated a Khamenei exit as a live 2026 risk, while a separate forecast report still described forced regime change in Iran as highly unlikely over short horizons and only 4-9% over one year.[2][3][12]

For a power-user building a workflow around this market, the useful angle is to treat it as an event-driven contract rather than a slow macro bet. Historical comparables suggest that succession in Iran normally moves through the Assembly of Experts and the clerical-security network, so the highest-signal inputs are any official announcement, state-media confirmation, detentions of senior clerics or Guards figures, or credible reporting that a replacement has been chosen or that Mojtaba can no longer exercise authority.[1][9][15] Programmatically, that means watching structured news feeds, Farsi-language state output, and calendar-dependent triggers around major religious, security, or parliamentary dates, because markets can reprice sharply on a single verified transition cue.[1][9][16]

The main catalyst set is therefore narrower than broad anti-regime unrest: a succession statement, a health or absence report that is formally acknowledged, or a visible shift in the Assembly of Experts’ role. Recent reporting has highlighted how opaque the succession process remains, with analysts noting that the formal mechanism exists but real power still sits inside established clerical and security networks, which makes surprise announcements the most important trigger for any automated alerting or conditional-order logic.[9][16]
