The main question is driven by whether the Gulf war remains active (raising spillover/accident hazard near Omani waters) and whether Trump's threats convert into deliberate action, which requires a concrete relationship breakdown; sub-question probabilities are blended as correlated contributing factors, with the accidental/spillover path weighted heaviest since it is the most plausible route to YES given the strict physical-impact and attribution criteria.

Sub-questions (4)

sq1
Will the US deliberately conduct a military strike on Omani territory or Omani military forces (e.g., in retaliation for Oman 'interfering' or aiding Iran) before January 1, 2027?
This is the scenario Trump's rhetoric points to, but deliberate strikes on a long-standing partner hosting US access agreements would be an extraordinary escalation; rhetoric-to-action conversion for such threats is historically very low.
w=0.25
sq2
Will an accidental or spillover US strike (misfire, interdiction, or strike on Iranian assets/vessels) physically affect Omani territory, territorial waters, or Omani forces before January 1, 2027, with credible-source consensus or a US/Oman claim that it occurred within Oman?
Given active US-Iran combat around the Strait of Hormuz, where Omani territorial waters (Musandam exclave) abut Iranian waters and shipping lanes, accidental or spillover incidents are the most plausible YES path; resolution requires physical impact and attribution consensus.
w=0.40
sq3
Will active US-Iran hostilities in/around the Strait of Hormuz continue (no durable ceasefire) through at least November 2026?
The underlying driver of both deliberate and accidental risk is ongoing war in the Gulf; a ceasefire would sharply reduce the hazard rate for the remaining window.
w=0.20
sq4
Will US-Oman relations deteriorate to concrete hostile actions (Oman denying US basing/overflight, interdicting US operations, or the US imposing sanctions/withdrawing personnel) before the end of 2026?
A measurable breakdown in relations beyond rhetoric would be a leading indicator that a deliberate US attack becomes conceivable; absent this, threats are likely bluster in a negotiation context.
w=0.15

Rationale

(a) Roughly four months remain (late August 2026 to January 1, 2027). (b) Status quo: six months of active US-Iran combat around Hormuz, including strikes on Larak Island adjacent to Musandam, have produced no credible report of US fire physically affecting Omani territory or forces; Trump's threats against Oman (May and August) have gone unfulfilled, and Oman remains a US basing partner and designated dialogue channel. (c) NO scenario: the war winds down or continues at similar intensity, the US keeps strikes focused on Iranian assets, Oman's Strait-toll diplomacy irritates Washington but only rhetorically, and any ambiguous projectile incidents near Khasab are attributed to Iran or 'unidentified' sources. (d) YES scenario: Oman finalizes a Strait administration deal with Iran that Trump views as sabotaging his talks, leading to a punitive strike on an Omani coastal facility, or more plausibly a US interdiction or strike on Iranian vessels/launchers in the crowded Musandam waters hits an Omani patrol boat or lands inside Oman's 12nm limit with Oman publicly claiming it. The accidental path dominates the risk, but the long record without such an incident implies a low monthly hazard.

What would change my mind

A confirmed report (US or Omani statement) of US ordnance landing in Omani waters or damaging an Omani vessel, or Oman revoking US basing rights after finalizing a Strait deal with Iran, would push me above 70%; a durable US-Iran ceasefire ending Hormuz combat operations would push me toward 2-3%.

## Question
Will the United States attack Oman before 2027?

## Description / Resolution Criteria
## Description
On August 17, 2026, it was reported that [US President Trump spoke to Fox News](https://www.foxnews.com/world/trump-confirms-irgc-backchannel-calls-irans-white-flag-surrender) about the ongoing challenges negotiating with Iran in the ongoing war surrounding the Strait of Hormuz.

> If Oman gets in the way, we’ll bomb the s--- out of them.

This is not the first time that the US President has threatened the Gulf nation. Back in May 2026, it was reported that [he warned Oman](https://edition.cnn.com/2026/05/27/world/live-news/iran-war-us-news#cmpoc4ge900003b6u9s3zjw35) not to interfere in the US negotiations with Iran. 

> Oman will behave just like everybody else or we’ll have to blow ‘em up.

Despite [long-standing economic and military US-Oman ties](https://www.aspistrategist.org.au/how-to-lose-friends-and-alienate-allies-trumps-approach-to-oman/), Oman's intermediary role in the US-Israel war with Iran has strained recent relations. 

## Resolution Criteria
This question will resolve as **Yes** if, before January 1, 2027, the United States carries out a military attack against Oman's territory or military forces. This can be purposefully or accidentally.

## Fine Print
Oman's territory includes territorial waters.

To qualify for this question, the attack must physically affect Oman's territory or military forces: cyberattacks, warning shots in international waters, or other actions without immediate physical impact will not count.

If it is disputed whether the United States is responsible for an attack, this question will refer to credible sources or may resolve as **ambiguous**. In case of an attack where there is no credible source consensus that it occurred within Oman's territory and neither the US nor Oman claims that it did, this question will not resolve based on that incident.

## Sub-question decomposition

## Required pre-forecast walkthrough

Before giving probabilities, walk through these explicitly:
  (a) The time left until the question resolves.
  (b) The status quo outcome — what happens if nothing changes from today.
  (c) A brief scenario that results in NO.
  (d) A brief scenario that results in YES.

## Calibration guidance

- **Estimate each sub-question in isolation.** Do not let your answer to one sub-question anchor your answer to another. This is the core of Fermi decomposition — independence forces more careful reasoning per factor.
- **Anchor on the status quo.** Require strong specific evidence to move far from it.
- 0.05 / 0.95 require strong, multi-source evidence. Avoid >0.97 or <0.03 unless the outcome is already settled or near-tautological — overconfident misses are punished heavily by the log score.
- **Anchor on prediction markets.** If liquid market prices (Polymarket / Kalshi) or a community forecast appear in the evidence, treat them as a strong, well-calibrated prior. Your final estimate should rarely sit more than ~15 percentage points from a liquid market on the SAME question — move further only with specific evidence the market lacks.
- **Treat research as fallible, not ground truth.** A single-source or "very recent" claim — especially one the evidence flags as unverified, possibly AI-generated, or low-credibility — must not drive you to near-certainty. When a load-bearing fact is unverified, keep at least 10-15% on the chance it is wrong.
- **Also provide a holistic estimate** — your overall gut feeling about the main question, BEFORE you see the mathematical combination. This serves as a sanity check: if the Fermi result and holistic estimate diverge wildly, something is wrong.
