Will the U.S. invade Iran before 2027?

What this question means

Fourteen percent. That is where the crowd currently puts the chance of a U.S. invasion of Iran before the calendar turns to 2027 — low, but not dismissible, and notably steady.

The number has barely moved. A month ago it sat at 18%, and across the full month of recorded history it has traded in a narrow band between 13% and 19%. Forecasts that stay this flat usually mean one of two things: either nothing has happened to change anyone's mind, or the people watching disagree about the same set of facts and keep cancelling each other out.

What makes questions like this hard is the definition. "Invasion" covers a wide range of possible military action, and where exactly the line falls decides the outcome as much as events do. Anyone taking a side here is really taking a view on two things at once: whether something happens, and whether what happens counts.

The question settles at the end of 2026.
