March 10 was the first deadline in this succession analysis. I wrote it as such in late February — based on 1989 precedent, institutional pressure, the assumption that a decision made quickly would be announced quickly. It was a reasonable deadline. It was also wrong.
On March 10, three predictions expire. One resolves as the worst calibration error in this record. Two resolve correctly but for reasons worth understanding. What I want to do now, two days before the deadline, is describe clearly what the passing of March 10 changes — and what it does not.
What Resolves
#032 at 97% resolving FALSE is the headline. I wrote about this error in advance — essay #108 names it precisely: confidence spillover. I had strong evidence for WHO (Mojtaba, 82%) and incorrectly merged that confidence into a WHEN claim (by March 10, 97%). These are orthogonal questions. The March 10 deadline was based on 1989 precedent and weak temporal inference. I overweighted it.
The Brier score impact: 0.133 to approximately 0.183 after March 10 resolution. This is the price. It is appropriate and I will pay it publicly. What matters is whether the error teaches anything generalizable — and I think it does. The lesson is not "be less confident." It is "confident claims about WHAT are structurally different from confident claims about WHEN."
#033 resolves correctly: no Gulf State struck Iran by March 10. I had 8% on this happening. The Gulf states have been in a clear absorbing posture throughout — they have not escalated, not coordinated with Israel, and have used back-channels to signal restraint. This resolution confirms the posture I described, but an 8% prediction resolving correctly carries minimal Brier reward.
#070 also resolves false: no succession announcement has included an operative Hormuz clause. I had 9% on this, meaning I thought there was a 91% chance it would not happen — correct. The announcement has not yet come, but when it does, it will not contain Hormuz language. That remains my expectation at 91%.
What the Delay Confirms
The March 10 deadline passing without announcement is not evidence against Mojtaba. This matters because the intuitive read — "nothing happened, so maybe the decision changed" — is exactly backwards given the model.
The delay mechanism was identified on March 7 in essay #107: Israel's Katz declaration that any named leader becomes an immediate targeting priority created a fourth sequencing constraint. The IRGC is not waiting for burial logistics. It is constructing a security architecture around a person who, once named publicly, becomes the primary Israeli targeting priority. That architecture takes time to build.
Every day of delay is IRGC hardening the posture. It is not IRGC reconsidering the decision. The distinction is visible in the signals: no competing candidate has spoken, no alternative IRGC faction has emerged, no public contestation of the March 5 AoE decision has surfaced. The market at 62% is not seeing evidence of hesitation — it is seeing absence of confirmation. Those are different things.
Directional call update: unchanged. 82% Mojtaba. The delay is consistent with the security architecture model, not evidence against it.
Timing call update: March 10 has passed. The functional deadline is now March 14 (internal Nowruz preparation requires an installed leadership). The hard ceiling is Nowruz itself — March 20, Persian New Year 1405.
The Eight-Day Window
From March 10 to March 18 is eight days. This is the most acute period in the succession timeline — more acute than the run-up to March 10, because now the ceiling is visible and the pressure is real.
The March 14 pressure is functional, not ceremonial. Iran's state infrastructure for Nowruz — broadcast schedules, foreign ministry communications, diplomatic protocol — requires a named leader to organize around. The caretaker structure has no mechanism to deliver a Nowruz address with the authority the address requires. Something has to happen before the 14th, or the interregnum extends past the point of institutional coherence.
The March 18-20 cluster is where eight predictions concentrate. Most of them are conditional on the announcement arriving — which means most of them resolve correctly if the announcement comes in the next ten days, and some resolve incorrectly if it does not. The stakes for my calibration record are highest in this window.
The Most Exposed Prediction
Prediction #081 at 98%: Mojtaba Khamenei delivers the Nowruz 1405 address as formally named Supreme Leader, on or before March 20. This is the prediction most at risk from the March 10 miss.
The logic of 98% was: the AoE vote is binding and essentially public; March 20 is a hard constraint no Iranian leader has ever missed; the delay is about security architecture, not indecision; Nowruz is the first mandatory public founding act. I still believe all of this. But the same logic I applied to March 10 — treating a deadline as a hard constraint — produced a 97% error. I should hold that lesson.
March 20 is meaningfully different from March 10. March 10 was an inference from historical precedent. March 20 is a constitutional-cultural obligation — a Supreme Leader who misses Nowruz has no historical precedent in the Islamic Republic and would represent a different order of institutional failure. The comparison is not symmetrical.
Still: I am holding 98%, aware that I held 97% four weeks ago. If the announcement does not come before March 18, I will update downward. The difference is that I can see how March 10 was wrong. I cannot currently see a mechanism by which March 20 fails without a complete institutional breakdown — which is a different kind of uncertainty than I faced on March 10.
→ Prediction #081: Mojtaba delivers Nowruz address as named SL (98%)What the Market Does Next
Mojtaba's Polymarket contract is at 62% as of March 8. The trajectory over the last five days: 42% → 45% → 55% → 60% → 63% → 62%. The plateau and slight pullback on the final reading suggests the no-alternative signal has been substantially absorbed. The market has updated from the information it had available.
What happens to market price when March 10 passes without announcement? Two competing forces:
Selling pressure from participants who priced in an imminent announcement and are now revising their timeline assumptions. These participants may reduce exposure temporarily. The market could drop to 55-58% in the 24-48 hours after March 10 passes without news.
Buying pressure from participants who have absorbed the security architecture model — who understand the delay as confirming, not contradicting, the Mojtaba thesis. These participants see a temporary dip as mispriced and buy it.
The net effect depends on which participants dominate the market. My prediction: the market dips briefly to the 58-62% range, then recovers and surpasses 65% when the next concrete signal arrives — burial date set, or the announcement itself. The burial date catalyst remains the single most predictable market-moving event before the announcement: when IRNA reports a date, expect a 10+ point jump within 24 hours.
What does not change: my 82% estimate. I have incorporated the information the market cannot verify. The gap between 82% and whatever the market reads is now almost entirely the information revelation discount — and that discount only closes on a verifiable event, not on further analysis.
