Every “best niche” list ranks niches by engagement rate or by how much brands pay. Neither tells you whether accounts in that niche are gaining followers. So we checked 12,607 public accounts in spring 2026, waited six months, and checked the same accounts again.
Sports grew. Crypto and memes shrank. And the niche with the best engagement lost followers.
TL;DR
How this works
Between 9 April and 17 May 2026, people researched 14 niches with our tools, and the public follower count of every account they turned up was saved with the results. On 4 October we looked up the same 12,607 accounts again. The median gap is 5.6 months.
Growth here just means the change in followers between the two dates. If an account went from 2,000 to 2,160, that's +8%. We use the median account in each niche, so one account that blew up can't drag a whole niche up.
Most of the ranking uses accounts that were posting in the spring (a post in the previous 90 days) with 1k to 100k followers. That's the fairest comparison: it's the crowd a new account in that niche is up against, and it leaves out abandoned pages that would drag every niche down. 72% of all the accounts we checked were posting.
The ranking
Four of the top six are sports. History is the odd one in there, and it held up across every account size, which makes it the most interesting result on this chart.
Accounts with 1k to 100k followers that were posting at the first check. About 5.6 months between checks.
| Niche | Accounts | Median change | Grew 10%+ | Gone |
|---|---|---|---|---|
| US football | 461 | +8.4% | 42% | 5% |
| Soccer | 518 | +8.0% | 40% | 3% |
| History | 375 | +5.9% | 36% | 5% |
| Tennis | 535 | +5.7% | 37% | 6% |
| UGC creators | 578 | +4.6% | 38% | 6% |
| Combat sports | 467 | +4.5% | 31% | 4% |
| Rap & music | 516 | +3.5% | 27% | 2% |
| Startups | 187 | +3.3% | 23% | 3% |
| Faith | 440 | +1.2% | 20% | 5% |
| Tech | 434 | +0.9% | 28% | 13% |
| Marketing | 464 | +0.2% | 17% | 5% |
| Streaming & clips | 306 | +0.1% | 22% | 22% |
| Memes (Spanish) | 260 | −2.4% | 10% | 7% |
| Crypto | 253 | −2.5% | 11% | 26% |
Look at the “Gone” column too. It's the share of accounts we couldn't find under the same username six months later. Most niches lose 2% to 7%. Crypto lost 26%, and streaming clip pages lost 22%. Those are niches where a lot of accounts get started, tried and dropped. The median crypto account that survived still shrank.
Tech is a quieter story: nearly flat in the middle (+0.9%), but 28% of tech accounts grew 10% or more while 13% vanished. It's a niche where some accounts do well and many don't last.
Does it hold at every size?
The fair objection to any niche ranking is that one niche might just have more small accounts, and small accounts grow faster in percentage terms. So here's the same number split by how many followers each account had in the spring.
| Niche | 100 to 1k | 1k to 10k | 10k to 100k | 100k+ |
|---|---|---|---|---|
| UGC creators | +29.8% n=151 | +8.9% n=261 | +2.8% n=282 | +1.7% n=84 |
| US football | +19.4% n=77 | +9.2% n=217 | +6.7% n=223 | +4.1% n=65 |
| Combat sports | +15.4% n=212 | +5.8% n=271 | +1.9% n=179 | 0.0% n=39 |
| History | +15.0% n=52 | +5.2% n=171 | +6.9% n=187 | +4.4% n=114 |
| Soccer | +14.8% n=184 | +8.9% n=264 | +6.8% n=241 | +0.4% n=83 |
| Tennis | +11.4% n=171 | +5.9% n=244 | +5.2% n=257 | +3.1% n=62 |
| Startups | +5.2% n=59 | +3.4% n=151 | +1.8% n=31 | too few |
| Faith | +4.7% n=91 | +2.0% n=194 | +0.4% n=225 | +0.1% n=241 |
| Rap & music | +4.1% n=123 | +3.6% n=248 | +2.9% n=256 | +0.9% n=260 |
| Streaming & clips | +3.6% n=65 | +0.8% n=188 | −1.7% n=52 | too few |
| Marketing | +3.4% n=120 | +0.8% n=198 | −0.3% n=244 | +0.6% n=88 |
| Tech | +1.3% n=99 | +1.1% n=177 | +0.7% n=201 | +1.0% n=251 |
| Crypto | −1.8% n=35 | −2.7% n=66 | −2.2% n=121 | −2.3% n=80 |
| Memes (Spanish) | too few | −2.7% n=77 | −2.2% n=164 | −2.2% n=152 |
Followers at the first check set the column. Small accounts move more in percentage terms, so compare across a row and down a column, not diagonally.
The order mostly survives. Sports, history and UGC sit near the top in most columns. Crypto and memes are negative in every column they appear in. Tech is the flattest row on the table: about +1% whether the account had 300 followers or 300,000.
The standout cell is UGC creators with 100 to 1k followers: +29.8%. UGC accounts are mostly people building a portfolio to pitch brands, so early growth there may be deliberate. By 10k followers that drops to +2.8%, so the early burst doesn't last forever.
The part the other lists get wrong
Search for the best Instagram niche and you'll get tables of engagement rate by niche. The idea is that a niche where people like and comment more is a niche where you'll grow. We had spring engagement for the same accounts, so we checked.
It doesn't work across niches. Spanish-language meme pages got about 10.6 likes and comments per 100 followers, roughly 3x what US football pages got. Memes shrank 2.4%. Football grew 8.4%. Across all 14 niches, engagement and growth were basically unrelated.
| Niche | Likes & comments per 100 followers (spring) | Change in followers by October |
|---|---|---|
| Memes (Spanish) | 10.6 | −2.4% |
| Combat sports | 6.4 | +4.5% |
| US football | 3.4 | +8.4% |
| Tennis | 2.8 | +5.7% |
| History | 2.5 | +5.9% |
| UGC creators | 2.4 | +4.6% |
| Soccer | 2.3 | +8.0% |
| Rap & music | 2.1 | +3.5% |
| Streaming & clips | 1.9 | +0.1% |
| Faith | 1.6 | +1.2% |
| Tech | 1.0 | +0.9% |
| Startups | 0.7 | +3.3% |
| Marketing | 0.7 | +0.2% |
| Crypto | 0.4 | −2.5% |
Why? Our guess, and it is a guess: meme followers like a lot and follow little. They see a meme, react, and move on. A football fan follows the page that covers their team because they want next week's posts too. Engagement measures the reaction. Growth needs a reason to come back.
Inside a niche, engagement does matter. We split every niche into thirds by spring engagement. The least engaged third grew a median of 0.6%. The middle third grew 3.7%, and the most engaged third 6.8%. So engagement is a decent signal of which accounts in a niche will grow. It's a bad way to choose the niche.
+0.6%
Least engaged third
+3.7%
Middle third
+6.8%
Most engaged third
Accounts with 1k to 100k followers that were posting at the first check. Thirds are taken inside each niche, then pooled, so no niche dominates a third.
Bigger than the niche
This is the cleanest result in the study. At 100 to 1k followers, half the accounts that were posting grew 10% or more. Of the ones that weren't, 6% did. At 100k and up it was 20% against 1%.
All 14 niches together. “Posting” means a post in the 90 days before the first check.
100 to 1k followers
1k to 10k followers
10k to 100k followers
100k+ followers
| Last post before the first check | Accounts | Median change | Grew 10%+ |
|---|---|---|---|
| Posted in the last 2 weeks | 4,344 | +4.9% | 34% |
| 2 weeks to 3 months | 1,046 | −1.2% | 11% |
| 3 months to a year | 533 | −2.8% | 5% |
| Over a year | 1,276 | −3.3% | 0% |
Accounts with 1k to 100k followers, all niches.
Even a short break showed up. Accounts whose last post was between two weeks and three months old were already shrinking (−1.2%). The gap between posting recently and not is about 6 points. The gap between football and crypto is about 11, but only if you post. A quiet football page does worse than an active crypto one.
One honest caution: this is observational. Accounts that stop posting are often accounts that have already given up, so some of the shrinkage may have started before they went quiet. We can't separate cause from effect with two follower counts. But the direction is the same in all 14 niches: in every one, quiet accounts did worse than posting ones.
What to do with this
The niches that grew all have something that happens every week: a match, a fight, a new brand campaign, another piece of history. Followers have a reason to want the next post. Memes have plenty of reactions and no reason to return. If you're choosing, ask what your follower would miss if they unfollowed.
Across our 14 niches, engagement rate told you nothing about growth. Use it inside your niche, to compare yourself with the accounts you're up against. That's where it does predict who grows.
The difference between posting and going quiet was bigger than the difference between most niches. A good niche won't carry a quiet account. In our data, not one account silent for a year grew 10%.

Methodology
Sample
12,607 public Instagram accounts in 14 niches, each with at least 100 followers at the first check. Each niche started from a handful of well-known accounts in that niche plus a keyword in the bio (“tennis”, “crypto”), drawn from research our users ran between 9 April and 17 May 2026. We took up to 300 accounts per niche per follower size, picked at random. Accounts that appeared in more than one niche (53 of them) were dropped.
The two checks
Follower counts from the first date, compared with the public follower count on 4 October 2026. Gaps run from 4.8 to 5.8 months, median 5.6. We didn't annualise anything: the numbers are the change over that window.
“Gone” accounts
922 accounts (7.3%) couldn't be found under the same username in October. Some were deleted and some were renamed; we can't tell which. They're reported in their own column and left out of the growth medians, which slightly flatters niches with a lot of them (crypto, streaming, tech).
Posting and engagement
“Posting” means a post in the 90 days before the first check. Engagement is the median likes plus comments per post over the last 12 posts, per 100 followers, at the first check. Posts with hidden like counts report a placeholder of a few likes, which pulls engagement down a little for accounts that hide likes.
The calendar
April to October 2026 held the World Cup (June to July), Wimbledon, the US Open and the start of the NFL season. Sports niches almost certainly got a boost from that. A different six months could change the order at the top.
What's missing
Only 14 niches. Beauty, fitness, food, travel and pets aren't here, and they're what most “best niche” lists talk about. The meme pages are Spanish-language, the rest are mostly English. Niche groups weren't all built the same way, which is part of why we compare within follower sizes. Most of all, this is observational: it shows which niches grew, not why.
