# US announces end of Iranian blockade by...? DataSnack's model puts this at 67% seven days from now (10 Nov 2026); the market's number (Polymarket) is 68%. It has no graded forecasts yet; the first is graded on 12 Nov 2026. ## DataSnack's read **The blockade is the price of any deal, so neither side wants to move first** An announced end to the blockade would be the clearest sign of a real US-Iran deal, with Hormuz transits about 65% below pre-conflict levels. The model's case rests on decay as the window shortens, plus talks progress and crude. ## The numbers - The market's number (Polymarket) now: 68% ([the market](https://polymarket.com/event/us-announces-end-of-iranian-blockade-byptptpt-20260713152715080)) - DataSnack's model, seven days from now: 67% - The market closes: 1 Jan 2027 - How it resolves: On July 13, 2026, Trump announced the United States would reinstate its naval blockade of Iran, targeting Iranian ships and customers. This market will resolve to “Yes” if the United States government, or an authorized representative of the United States government, publicly and officially announces the end, termination, lifting, or suspension of the United States’ naval blockade on Iranian ships and ships of Iranian customers, between market creation and the specified date, 11:59 PM ET.

It is nudged by reported progress in the Qatar-mediated talks, then by crude oil, which rises when Hormuz shipping tension rises and pushes the pressure to end the blockade. - With no announcement this week, the chance shrinks at about 0.68 times the pace of a constant hazard as the window to the date shortens. DataSnack's author expected 0.69; the data say 0.68, fitted on the same days the replay scores. Fits past data roughly. - Each 1.0 rise in the talks-progress reading over a week moves the chance by about 0.618 in log-odds in log-odds. DataSnack's estimate, not yet tested on data. - Each $1 rise in crude over two weeks, a sign of a tighter Hormuz and blockade standoff, moves the chance by about 0.016 in log-odds in log-odds. DataSnack's author expected 0.015 in log-odds; the data say 0.016 in log-odds ± 0.0066, fitted on the same days the replay scores.
