## DataSnack's read

**A ceasefire hinges on who sets the sequence, not on who wants peace**

The gap between definitions shows how far a durable halt is from a partial pause. The model's case rests on time decay and crude oil, and it missed by 5.5 points on 2026-10-05 when talks news moved the number.

## The numbers

- The market's number (Polymarket) now: 70% ([the market](https://polymarket.com/event/russia-x-ukraine-ceasefire-agreement-by))
- DataSnack's model, seven days from now: 70%
- The market closes: 1 Jul 2027
- How it resolves: This market will resolve to “Yes” if there is a ceasefire agreement between Russia and Ukraine by the specified date, 11:59 PM ET. Otherwise, this market will resolve to “No”. A ceasefire agreement refers to any mutually-agreed suspension of direct military engagement between Russia and Ukraine, which is either officially announced by both countries or confirmed by a consensus of credible reporting to have been mutually agreed by both countries.

- Record: It has no graded forecasts yet; the first is graded on 12 Nov 2026.
- Replay on the last 52 days: off by 1.7 points against 1.7 points for standing still; closer on 0 of 52 days
- Fitted on 58 days of history

## How the model works

The chance of a ceasefire by the end date erodes as time runs out with no deal, after which a small adjustment follows the week's move in crude oil, which the scan found to be the strongest tracker of the market.

- With no deal this week, the chance of a ceasefire by the date decays at 0 of a constant-hazard pace as the window shortens. DataSnack's author expected 1; the data say 0, fitted on the same days the replay scores. A rough rule.
- Each $1 weekly rise in crude shifts the ceasefire chance by about 0 in log-odds in log-odds, a link the data show but that may reflect a shared driver. DataSnack's author expected 0.0067 in log-odds; the data say 0 in log-odds ± under 0.01, fitted on the same days the replay scores. A rough rule.
