Will Iran withdraw from the NPT before 2027?
What the market is pricing
The market is pricing Iran's withdrawal as unlikely, with odds in the teens reflecting a low baseline probability of such a formal diplomatic move. The probability rose slightly over the past day, suggesting modest recent shifts in sentiment, though the overall assessment remains that withdrawal before the end of 2026 is a long shot. The modest trading volume indicates moderate but not intense market interest in this outcome.

What could move it
- Official Iranian government announcements or UN notifications would directly trigger or rule out resolution; the mechanism is binary and requires formal written notice.
- Roughly two years remain until the deadline — enough time for geopolitical developments to shift odds, but a formal withdrawal would be a significant and deliberate state action, not a routine occurrence.
