Sprout Social’s platform analysis found that for Instagram Reels and posts, more than 50% of creators have audiences where 70%+ of viewers aren’t following them. Stories work differently (built for existing followers), where only 10% of creators see that same non-follower majority. It’s more evidence that on the biggest discovery formats, algorithmic distribution has become the real gatekeeper, not follower count.

What it means
The full breakdown by format: 60% of creators see a majority-non-follower audience (70%+ non-followers) on Reels, 50% see it on posts, and just 10% see it on Stories. That’s a six-fold difference between the format built for discovery (Reels) and the format built for retention (Stories).
The mechanism explains the gap.
Reels and feed posts are the formats algorithmic recommendation engines actively push to non-followers as part of discovery surfaces, while Stories are designed to be seen mainly by people who already follow an account.
Sprout Social notes the same dynamic shows up on TikTok, where the network’s own explanation of its algorithm treats “following an account” as one input among many, not the determining factor in what gets shown.
One caveat worth flagging: unlike the report’s survey-based stats, this reach analysis doesn’t disclose how many creator accounts it’s drawn from, so it should be read as directional, a real pattern Sprout Social observed on its platform, rather than a statistically representative sample the way the consumer and marketer survey numbers are.
Why it matters for B2B marketers
If you’re sizing expected campaign reach off a creator’s follower count, that math is increasingly wrong for the formats doing the heavy lifting.
A creator with a modest following can still post a Reel that reaches well beyond their followers, while a creator with a huge following can post a Story that barely leaves their existing audience. Before locking in a creator based on follower count alone, ask which format the campaign will run in, and consider testing mid-tier creators on Reels or feed-post content rather than assuming a bigger name guarantees bigger reach.
