This question is based on this post by Peter Wildeford, in which he outlines five possible outcomes of the Israel-Iran conflict by the end of 2025. Scroll down to see descriptions of the five scenarios, or click through to the post for more details.
Most likely, I will resolve this question to whichever of the five scenarios below comes closest to describing my sense of the conflict at the end of 2025.
If it feels to me like the actual thing that happens is equally similar to two of the scenarios below, then I may resolve two of the scenarios to 50/50 (and similarly if it feels equidistant from three of the scenarios, etc.). However, I will try to avoid this; I estimate a 75-80% chance that I will resolve this question 100% to one of the choices.
This is obviously subjective, so I will try to answer questions in the comments, so that market participants aren't blindsided by my eventual resolution.
Scenario 1: Deal by EOY2025 (25% probability)
Key elements:
Trump pushes through a deal allowing limited enrichment at Fordow under monitoring
Iran accepts caps at 20% enrichment with enhanced IAEA inspections, destroying their 60% enriched stockpile
Israel grudgingly accepts US security guarantees and enhanced defense cooperation
Europe holds back on snapback in exchange for Iranian concessions
Sanctions relief from the US is phased in over 2-3 years tied to compliance milestones
Scenario 2: Iran gets nuke by EOY2025 (10% probability)
Key elements:
European snapback triggers Iranian NPT withdrawal
Iran sprints to 90% enrichment using new IR-6 centrifuges at Fordow
First Iranian nuclear device assembled within 60 days
Israel launches desperate strikes including possible tactical nuclear use
US forced to choose between accepting nuclear Iran or direct military intervention
Regional nuclear cascade with Saudi program accelerating
Scenario 3: Large-scale war by EOY2025 (35% probability)
Key elements:
Israeli strikes expand to infrastructure targets across Iran
Iran activates Hezbollah's 50,000+ rockets and attempts Hormuz closure
US drawn in to protect Gulf shipping and US military bases
European forces deploy to secure energy supplies
Conflict potentially spreads to Iraq, Syria, and Lebanon
Potential global recession triggered by $150+ oil prices
Scenario 4: Managed Escalation - The New Normal (23% probability)
Key elements:
No deal reached but no war either
Israel conducts strikes every 3-4 months to “mow the grass”
Iran enriches steadily but strategically stays below 90%
Iran orders calibrated proxy attacks that avoid triggering full war
US and Europe provide just enough support to prevent collapse
Economic warfare continues with sanctions and sabotage
Scenario 5: Iran voluntarily gives up its nuclear ambitions by EOY2025 (7% probability)
Key elements:
Iran voluntarily gives up its nuclear ambitions, likely through regime change within Iran due to Khamenei dying or getting overthrown but possibly due to bowing to overwhelming pressure
No deal is necessary as Iran is no longer pursuing nuclear weapons, even at threshold status.
Iran potentially re-enters the international order
Iran potentially trades complete nuclear dismantlement for massive sanctions relief and security guarantees
