In short
The answer first
Win probability is a model's estimate of the chance of each match outcome at a particular moment. Models can use the score, time remaining, team strength, red cards and match events, but inputs differ by provider. A 70% estimate means similar model situations produce that outcome about seven times in ten; it does not mean the result is settled.
Key takeaways
Win probability is model-specific and changes as new information arrives.
Score and time usually have major influence.
Red cards and pre-match team strength may be included, depending on the provider.
A sudden chance can move an event-based model even when no goal is scored.
Calibration over many matches matters more than one surprising outcome.
A forecast for this moment
At kick-off, the estimate may reflect team strength and home advantage. After an early goal, the score and remaining time reshape the forecast. With five minutes left, the same one-goal lead normally carries more weight than it did in the first half.
The percentage is conditional on the information and assumptions inside that model.
Probability allows surprises
A team with a twenty per cent chance still wins sometimes. That outcome does not by itself prove the estimate was wrong. A useful model should be evaluated across many comparable predictions.
The number should therefore be read as uncertainty made visible, not as a live scoreboard of destiny.
Ask what moved the line
If the probability changes sharply, identify the event: a goal, dismissal, penalty, major chance or the simple loss of remaining time. Different providers may respond differently because their inputs and weighting differ.
The most useful display connects the movement to the football, allowing the viewer to understand why the match state changed.
