Overwatch – When Are Loot Boxes Populated?

overwatch

Are the contents of a loot box determined at the time it is awarded or when it is opened?

For example, if you collect multiple loot boxes before a special event but opened them during the special event, would they have the potential of spawning rewards from that event?

From the Overwatch Wiki

Loot Box's contents are generated when players earn or buy them, not when Loot Box is opened[1]. For example, any Loot Box acquired before installing July 19, 2016 patch will not contain any of Ana's items.

Loot Box items are decided once they are obtained, meaning that you cannot save Loot Boxes until new items (highlight intros, skins, etc.) come out, as you will only get what was available at the time.

To summarize, the loot is determined when the box is earned/purchased. This is likely to discourage hording loot boxes until a special event or new items come out and then opening all your loot boxes in hopes of getting a special event item/new item.
