Engagement
A typical post picks up 43 interactions against 819K followers, an engagement rate of 0.005%. Measured over 27 original posts, its engagement rate beats 26% of 3,758 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 29K times each, and 0.149% of those impressions turn into an interaction. That is about 3.51% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.9 posts a day over the last 30 days, with activity on roughly 60% of days. Most posts go out around 13:00 UTC, and Monday is the busiest day of the week. Of the 27 posts sampled, 44% carry an image or video, 11% are part of a thread and 44% link out. The account's strongest tracked post pulled 2.3K interactions, about 53x its own typical post.

Compared with accounts its own size
ARK Invest's engagement rate beats 26% of the tracked X accounts closest to it in follower count (3,758 accounts, accounts of similar size (decile 9 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 12% 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.
Where this sits in the catalog
At 0.005%, ARK Invest sits above the 10th percentile of the 36,521 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.012%.

Posting timing
This account posts most often around 13:00 UTC, and Monday 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.

A cancer vaccine that may cut deaths in half is real, and the same process could theoretically be pointed at any solid tumor. The catch: every dose has to be built from scratch for one specific person. @GrousARK, @skorusARK, and @wintonARK on why that's both the breakthrough and the bottleneck. https://t.co/D8UuKA3Tue

Cathie Wood says the US should measure its debt against national wealth, not gross domestic product (GDP). Do you agree this is the better way to look at it, or is GDP still the right gauge? Share your thoughts. ⬇️

Things from the August “In The Know” to keep an eye on before the September episode: • Will core consumer price index (CPI) fall below 2% by December? • Will the US Dollar Index climb toward 102.6 as ARK's Kalshi-powered forecast suggests? • Will oil prices keep falling as the United Arab Emirates (UAE)-led supply glut grows? • Will unemployment among 16-24 year olds drop below 7.5% this year? • Will Michigan consumer sentiment climb back above 65? We'll be watching. https://t.co/ftcfGPNt0B

Reading these numbers
A typical post picks up 43 interactions against 819K followers, an engagement rate of 0.005%. Measured over 27 original posts, its engagement rate beats 26% of 3,758 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end.

- What is ARK Invest's engagement rate on X?
- ARK Invest (@ARKInvest) has an engagement rate of 0.005%, based on the median interactions across 27 original posts from the last 30 days against 819,452 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.005%, ARK Invest sits above the 10th percentile of the 36,521 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 @ARKInvest have real engagement?
- Its engagement rate beats 26% of the tracked X accounts closest to it in follower count (3,758 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 @ARKInvest post?
- Most posts go out around 13:00 UTC, and Monday is its busiest day, at roughly 2.87 posts per day across the measured window.
