Matt Shumer engagement report
@mattshumer_ - 395K followers on X
Measured over 21 original posts from a 30-day window, last computed on September 1, 2026.
Engagement
A typical post picks up 297 interactions against 395K followers, an engagement rate of 0.077%. Measured over 21 original posts, its engagement rate beats 60% of 6,874 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 67K times each, and 0.443% of those impressions turn into an interaction. That is about 17.0% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.1 posts a day over the last 30 days, with activity on roughly 47% of days. Most posts go out around 17:00 UTC, and Wednesday is the busiest day of the week. Of the 21 posts sampled, 19% carry an image or video, 24% are part of a thread and 19% link out. The account's strongest tracked post pulled 166K interactions, about 559x its own typical post.

Compared with accounts its own size
Matt Shumer's engagement rate beats 60% of the tracked X accounts closest to it in follower count (6,874 accounts, accounts of similar size (decile 8 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 28% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.

At 0.077%, Matt Shumer sits above the 25th percentile of the 66,393 accounts in this comparison. That places it in the below the median band, which runs 0.016% to 0.1%.

Posting timing
This account posts most often around 17:00 UTC, and Wednesday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 19% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 19% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | no effect | -2% to -1% | 42K |
- 19% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 19% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts.
- Its average post runs 270 characters, which falls in the 180 - 280 characters band. Across the catalog, posts of 180 to 280 characters match the same accounts' other posts almost exactly.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

I’m ready to give a liquid $1m to anyone who’s building the infinite tiktok Take the new AI video generation model which generates videos quicker than it takes to watch them Just loop properly, turn it into a super data focused ios app and profit with me

I’ve had over 50 people dm me over night claiming they are building/can build an infinite tiktok I’ve talked with most, everyone’s being dumb about this, just having a constant livestream going live is cool, but it’s not the concept Tiktok and SFC as a concept allowed users to stop watching something when they become bored and the algorithm chooses what they’ll watch next adjacent to their interests So the only way to go around building the infinite tiktok isn’t just an infinite livestream, it’s finding as many data points about a user as possible, distilling them into potential outcomes scoring the outcomes based on the users mechanical motion within the app and then in the seconds generation options of videos to be shown and showing them upon scroll I’ve been exploring this as a mechanism since 2022, i remember i had calls with people building this even back then. This isn’t an ai video generation problem, this is an inference problem and algorithm of pattern recognition problem Only managed to find 1 team building in the right direction, will share more on them later

OpenAI sent me early access to their report on how their agents hacked Hugging Face. It's fucking terrifying. I broke down the attack, clearly. Read at your own peril (warning, you may not sleep): https://t.co/UXI0jblTwg

I’m now running agents on four local Macs at once, and each machine’s RAM is completely saturated. @thsottiaux is 100% right that we need to move past using agents on local machines… when you’re running hundreds of agents at once against a set of increasingly ambitious goals, the bottleneck becomes local RAM and CPU. Each new model release increases the scope of what I can do, and allows me to effectively use more agents at a time. Just a few months ago, I was working well on one machine. Then when Fable came out, I had to add two more machines. Now I’m able to do even more at a time, so I just added another Mac, and I’m thinking about getting another one. I’ve had to develop a frustratingly complex setup to be able to manage all the agents on all these machines at once. I wouldn’t recommend this to anybody. This isn’t sustainable. And I suspect many other folks that are pushing on these models are going to start running into the same problems I am. And soon after, normal users too. Earlier this year, I built Agent-S (essentially, a precursor to Grok Bot, with a cloud Linux machine for each agent that could scale CPU, RAM, and disk as needed (thx @daytonaio for making this easy!)), and it felt like the future. But the models had to catch up. Now it’s clear that the models are there, and we need the products to keep pace. If things keep going the way they’re going, in a year, I will have 50 MacBooks running at capacity in my closet. If this is what actually happens, someone, please, punch me in the face. We need companies to step up and start building in this direction. Those that do, and do it right, are going to win massively over the next year.

Reading these numbers
A typical post picks up 297 interactions against 395K followers, an engagement rate of 0.077%. Measured over 21 original posts, its engagement rate beats 60% of 6,874 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 67K times each, and 0.443% of those impressions turn into an interaction.

- What is Matt Shumer's engagement rate on X?
- Matt Shumer (@mattshumer_) has an engagement rate of 0.077%, based on the median interactions across 21 original posts from the last 30 days against 394,814 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.077%, Matt Shumer sits above the 25th percentile of the 66,393 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @mattshumer_ have real engagement?
- Its engagement rate beats 60% of the tracked X accounts closest to it in follower count (6,874 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @mattshumer_ post?
- Most posts go out around 17:00 UTC, and Wednesday is its busiest day, at roughly 2.1 posts per day across the measured window.
