US x Iran Effective Ceasefire begins by...? (2 week pause)
Slight lean to No: the market already prices in a low chance, and with no fresh evidence of a 14-day pause starting and completing by Nov. 8, the deadline looks tight.
Analysis
As of 2026-11-08, there is no fresh reported evidence here of a new U.S. strike on Iran, but there is also no sign that a full 14-day qualifying pause has already been completed before the market deadline. That leaves the setup heavily dependent on the absence of a military action since the relevant start date, which is hard to confirm without official updates.
With the end date arriving today, the main question is timing: whether the market has already crossed the 14-day threshold in Iran Standard Time. In the absence of recent confirmation, the safer read is that the market’s No side remains favored, though the Yes chance is still real if no qualifying action occurred for two weeks.
Arguments
For
- A 14-day stretch without a qualifying U.S. air or missile strike against Iran is enough for Yes under the rules.
- The rules exclude intercepted munitions and many lower-level actions, which makes a qualifying reset less likely than a casual reading might suggest.
Against
- The end date is immediate, so any unresolved ambiguity about the start of the 14-day period works against Yes.
- A single qualifying U.S. air strike or surface-to-surface missile strike on Iranian territory during the window would force No.
Key drivers
- The market ends today, so there is limited remaining time for a full 14-day qualifying pause to be recognized.
- No fresh news in hand means there is no concrete sign that the required no-strike window has clearly been completed.
Risk factors
- If the most recent qualifying U.S. strike was more than 14 days ago in Iran Standard Time, the Yes outcome can lock in quickly.
- Official or consensus reporting could surface that no qualifying action occurred during the full window, which would push the result to Yes.
Scenarios
Best case
If it is confirmed that the 14-day period started by Oct. 25, 2026 and no qualifying U.S. strike occurred through Nov. 8, Yes rises to about 45%.
Most likely
Most likely, the market closes with no clean confirmation of a completed 14-day pause, and Yes ends around 23%.
Worst case
If a qualifying U.S. strike on Iran is reported on Nov. 8, 2026 or within the prior 14 days, Yes falls to about 5%.
