Will the Iranian regime fall before 2027?

Platform comparison

Market context

Polymarket prices this contract at **7% YES**, implying traders think the Islamic Republic is far more likely to survive than to lose effective control by 31 December 2026. The market settles on whether the current ruling system is overthrown, collapses, or otherwise ceases to govern, so the relevant question is not simply whether unrest persists, but whether the Supreme Leader’s office, the Guardian Council and the IRGC-backed security state lose core governing power over Iran.

That low probability fits the recent historical pattern. After the 2025–26 protest wave, Johns Hopkins notes there are no signs of imminent collapse, including no defections in the military or broader political system, while the International Institute for Strategic Studies has argued that the regime has re-established control after mass protests.[1] The broader academic and policy literature on Iran repeatedly treats regime survival as the default unless security institutions split; even sources that describe severe strain generally still see institutional cohesion as the key barrier to regime change.[2][3] That matters for a prediction market: price action here is less about street anger than about whether coercive institutions actually fragment.

For traders on Polygon, the practical catalysts are succession and security signals, not rhetoric alone. Watch for any credible reporting on elite defections, unusual IRGC redeployments, a change in Supreme Leader succession handling, or a breakdown in state payroll, communications and command chains; those are the sorts of developments that could move a USDC-settled conditional token sharply before expiry. Reuters, BBC and other major outlets have all framed the regime as intact but under pressure, which means the next meaningful repricing would likely require a concrete institutional shock rather than another round of sanctions, protests or inflation headlines.[4][6]
