## DataSnack's read

**A deal waits on the blockade, and neither side will move first**

A Hormuz deal decides whether shipping through the strait, down about 65% from pre-conflict levels, normalizes. The model's 38% in seven days rests on window decay, talks news and the 10-year yield, against 34% now.

## The numbers

- The market's number (Polymarket) now: 34% ([the market](https://polymarket.com/event/us-iran-hormuz-agreement-byptptpt-20260803235957575))
- DataSnack's model, seven days from now: 37%
- The market closes: 1 Jan 2027
- How it resolves: This market will resolve to “Yes” if a diplomatic agreement between the United States and Iran over traffic in the strait of Hormuz is announced by the specified date, 11:59 PM ET.

## How the model works

The chance of a by-date deal shrinks as the window closes. The talks reading adds news that can lift it, and the 10-year Treasury yield, which the scan found moves against the market's number, is read over 14 days to temper it.

- With no deal this week, the chance of an agreement by year-end shrinks as the window closes, at 0.18 of a constant-hazard pace. DataSnack's author expected 0.17; the data say 0.18, fitted on the same days the replay scores. A rough rule.
- Each unit rise in the reading of Qatar-mediated talks progress moves the chance by 0.506 in log-odds in log-odds. DataSnack's estimate, not yet tested on data.
- Each percentage point rise in the 10-year Treasury yield over two weeks moves the chance by -0.39 in the following week. DataSnack's author expected -0.3; the data say -0.39 ± 0.26, fitted on the same days the replay scores. Fits past data roughly.
