Strait of Hormuz

From the reporting ledger · newest report 29 Oct 2026

The ledger holds 3,369 sentences about the strait. Grouped by the event they report, they make 2,111 events: 16 corroborated, 67 reported by two, 2,028 single source. The ledger also holds 1,078 sentences the event rule could not place; each counts on its own sources. 62 of those events were carried by several reports that all ran in one outlet or in the same words; repeated is not corroborated, so each counts by its separate sources. No claim on this record sits beside a live report that gives a different answer about the same incident. That counts live claims only, after any replacement, and only pairs our test could match incident for incident. 2 claims were replaced by a later report since 3 Sep; they are kept, marked, and not counted here. The newest of the best-supported are below.

The Hormuz record, as it stands today

The record is rebuilt from our data on every deploy. News reporting, our own coverage count and prediction-market prices are kept as separate layers, each with its source. Software reads the same record over MCP.

How long we’ve kept it

158 days

Tracked as an event since 2026-05-24

In our daily read of 2026-10-29, it came up 130 times across 34 of the subject areas we cover.

Our coverage right now

steady

Today: 5% below its 3-week baseline in how much our sources wrote about it, not whether passage is safer.

That measures our attention, meaning how much our sources write about the strait, not the strait’s condition.

Prediction markets on it

33 markets

Questions we have cited since 2026-05-24. Their prices are the markets’ own, never our estimate.

Replaced, never erased

When a later report replaces a claim, the record keeps the first one, marked, with the date and the reason.

See every claim in the Hormuz record

The ledger keeps 2 replaced claims, each marked, and none is about the strait’s own reporting, so none is shown here. The record’s change log counts every replacement and shows the newest.

Returns the same record this page is built from: its claims, their sources and dates, and how fresh each part is.

Who it serves

Who reads it

The same record answers different questions. Three people who read the Hormuz record, and what each one asks of it:

  • A maritime operator asks: Is passage through the Strait of Hormuz becoming more or less available, safe or costly, and why?

  • An energy desk asks: Is Gulf oil and gas supply at risk this month, and why?

  • An escalation analyst asks: Is the conflict between the United States and Iran escalating or easing?

AI systems & agents

Current entity and event state over MCP and REST. Every published claim names where it came from; where a direct link to the source exists, the record carries it. No key for reads.

Analysts & desks

Daily briefs, the wire, and grounded answers. On the Hormuz record, 10 of 10 published claims link straight to the source they came from, measured 29 Oct. That rate covers the record's published summary only; the reporting ledger behind it holds 3,369 sentences and is not part of this count.

We keep a source-traced record. The market prices in it are one labeled sensor: quoted as the markets’ own and graded in public against how events resolve: the calibration record.

The entity count is a published cut of the most-covered names. The full set we track is larger. The daily record lists what we read each day.

How a reading is made

  1. Sources. News, filings and official notices are read every day. See what we read.
  2. Relate. Each report is tied to who did what, where and when.
  3. The record. Each claim is kept with every source that carried it.
  4. Readings. A Watch shows the part of the record you asked about, newest first, with how well each claim is supported.
  5. Corrections. A replaced claim is marked, never erased.
