## DataSnack's read

**Israel's airspace odds hinge on Lebanon escalation, not the calendar**

A closure order would signal a regional escalation that reaches aviation, insurance and shipping decisions. The model's case rests on reporting of a possible Beirut strike lifting the odds, with 27% in seven days.

## The numbers

- The market's number (Polymarket) now: 24% ([the market](https://polymarket.com/event/israeli-airspace-closed-by))
- DataSnack's model, seven days from now: 24%
- The market closes: 1 Jan 2027
- How it resolves: This market will resolve to “Yes” if Israeli Airspace (The Tel Aviv Flight Information Region (FIR)/LLLL) is closed between market creation and the specified date, 11:59 PM ET. Otherwise, this market will resolve to “No”.

- Replay on the last 40 days: off by 2.9 points against 3.2 points for standing still; closer on 20 of 40 days
- Fitted on 45 days of history

## How the model works

With no closure this week, the chance of closure by the end of December decays as the window shortens. A rise in reporting that Israel will strike Beirut nudges the odds up.

- With no closure this week, the chance shrinks as the window shortens, at 0 of the pace of a constant hazard. DataSnack's author expected 1; the data say 0, fitted on the same days the replay scores. A rough rule.
- Each point of rise in the Beirut strike reading over 3 days moves the closure odds by 0.287 in log-odds in log-odds. DataSnack's author expected 0.25 in log-odds; the data say 0.287 in log-odds ± 0.29, fitted on the same days the replay scores. A rough rule.
