For anyone trying to grow an Instagram presence from scratch, the first month appears to be everything — and smaller accounts are seeing the biggest relative gains. That’s the headline from new data released by Outfame, an AI-powered growth service that studied nearly a thousand customer accounts to quantify what early follower growth actually looks like.
Daily follower readings of Outfame customer accounts show 86 percent grew in their first month, with results broken down by account size and niche.
Outfame, which operates out of Los Angeles and offers AI-driven growth for Instagram and TikTok, published its Instagram Growth Statistics 2026 based on data drawn from its own customers. Across 981 accounts measured at the 30-day mark, the median account picked up 346 new followers — equivalent to 15.8 percent of its starting follower count. A striking 86 percent of those accounts saw positive growth in their first month on the service.

The underlying data comes from daily snapshots of each account’s public follower count. Outfame records those readings once per day while the account remains on an active paid plan, beginning the day growth is initiated. In total, the study draws on 164,963 daily readings across 7,271 Instagram accounts that started between Feb. 1 and May 31, 2026, with tracking continuing through Oct. 29, 2026.
Early gains dominated the timeline. Among accounts that grew over a full 90-day period, the typical account had already achieved 62 percent of its total 90-day increase by day 30, based on 264 such accounts. Looking at all 340 accounts with measurements at both day 30 and day 90, a full 78 percent of the combined net gain across 90 days came within those first 30 days. The median gain climbed to 483 followers by day 60 (across 577 accounts) and to 533 followers by day 90 (across 417 accounts).
But results varied considerably around those medians. The middle 50 percent of accounts gained between 73 and 549 followers in the first 30 days, showing that outcomes are far from uniform.
Starting account size had a much bigger impact on percentage growth than on raw follower numbers. Accounts that began with fewer than 1,000 followers gained a median of 341 followers — a massive 69.4 percent increase — and 94 percent of them grew. Those with 1,000 to 9,999 followers gained a median of 359, representing 12.5 percent growth, with 90 percent seeing gains. Accounts in the 10,000 to 99,999 range gained a median of 288, roughly 1 percent of their starting count, and 70 percent grew. Accounts above 100,000 followers were excluded because the sample size was too small.
Niche also played a role. Travel accounts posted the highest median first-30-day gain of the nine niches measured, at 379 followers across 138 accounts. Health and wellness followed closely at 361, with fitness at 346. Food reached 341, music 324 and fashion 310. Beauty accounts gained a median of 205, art 187 and business 130. Outfame’s AI assigned each niche based on the account’s public profile and posts, and niches with fewer than 40 measured accounts were not reported.
The study also contextualizes its customer data against figures Instagram and Meta have published. Instagram hit 3 billion monthly active users in September 2025, per TechCrunch. In April 2026, Instagram said 75 percent of its U.S. recommendations now come from original posts. Meta’s family of apps averaged 3.64 billion daily active people in September 2026, according to the company’s third-quarter results.
Gain at day 30, 60 or 90 is defined as the reading closest to that day (within three days) minus the first reading, and only accounts still on a plan that day are counted. Medians are used to prevent a few very large accounts from skewing the results. The study excluded 394 accounts whose count jumped above five times or fell below one-fifth of the starting count, typically due to a username change or a failed reading.

Why it matters: For creators and small businesses investing in Instagram growth, this data suggests that early momentum is critical and that the first month may disproportionately determine overall results. The sharp contrast in percentage gains between smaller and larger accounts also implies that growth strategies need to be tailored to account size — what works for a fledgling account may not move the needle for a mid-sized one.
