You can usually see who voted on your Instagram Story poll by opening the Story, swiping up, or tapping the activity/viewers area to view the poll results list. Instagram shows the voters, but not necessarily which exact option each person picked in every view.

How to check

  • Open the Story that has the poll.
  • Swipe up on the Story, or tap the activity/viewers area.
  • Look for the poll results or voter list.
  • Tap an option if Instagram shows the breakdown by choice.

Important note

Some tutorials say you can see the names of people who voted, while others note that you may not always see which answer each person selected. Availability can vary by Instagram version and poll format.

If you do not see it

  • Make sure you are checking the original Story that contains the poll.
  • Try updating Instagram.
  • Check right after posting, since Story interactions are tied to the Story viewer panel.
