Yes, Instagram does show who viewed your story. To see who has viewed your Instagram Story, you can open your story and swipe up on the screen. This will display the number of viewers as well as the Instagram usernames of the people who have seen each photo or video in your story

. Only the person who posted the story can see this list of viewers. The viewer list updates in real-time while the story is active, which lasts for 24 hours, plus an additional 24 hours during which the list and view counts remain accessible

. Instagram does not show how many times someone viewed your story, only that they viewed it

. If you shared your story to Facebook, you can also see who viewed it on Facebook by scrolling down in the viewer list

. In summary:

• Open your Instagram Story.
• Swipe up on the screen.
• View the list of usernames who have seen your story.
• The list is visible only to you and updates in real-time during the story's active period.

This feature is built into Instagram to let users track engagement with their story content
