What's the difference between win probability and predicted win probability?

Win probability represents the likelihood (in percent form) of winning the opportunity. You manually set the win probability at the opportunity level for the sales stage.

If you don't want your sales stages to control opportunity win probability, make sure that no value exists in the win probability field. The predicted win probability displays the automated predicted win probability based on artificial intelligence (AI), system learning, and other data science capabilities. It provides a percentage of the predicted win probability in comparison to other opportunities from your sales organization or a prediction about the close date of the opportunity. For example, the artificial intelligent models might suggest a win probability for an opportunity that's significantly different to the salesperson's estimation. In that case, your sales application displays a warning icon on the Opportunities page.

You can hover over a warning indicator icon next to the Win Probability (%) field which is displayed only when the differences between the win probability percentage value and the predicted win probability percentage value is greater than the defined threshold. The text is read only and displays both win and AI predicted probability values as well as the Opportunity name.
