The fall of the Iranian regime would be an extreme macro shock event. The most direct impact is on Crude Oil, as Iran is a major producer and instability in the Strait of Hormuz could sever global energy supplies, causing prices to spike. Gold would rally as a safe-haven asset due to geopolitical uncertainty. US 10Y Yields could fluctuate wildly due to 'flight to quality.' For equities (S&P 500), while the energy sector might benefit, overall uncertainty is generally negative.

The prediction market currently assigns a ~22.5% probability to regime change within the year, which significantly diverges from mainstream think tanks and intelligence consensus. Mainstream experts generally argue that unless there is a full-scale foreign invasion and occupation of the capital, highly organized authoritarian regimes backed by loyal military forces (like the IRGC) rarely collapse completely within a few months, even under extreme economic stress and localized conflicts (assessed probability usually <5%). The market premium largely stems from retail panic and speculative hedging against uncontrollable black swan events, rather than grounded political science modeling.
