SpaceX engagement report
@SpaceX - 42M followers on X
Measured over 68 original posts from a 30-day window, last computed on August 31, 2026.
Engagement
A typical post picks up 9.6K interactions against 42M followers, an engagement rate of 0.023%. Measured over 68 original posts, its engagement rate beats 60% of 3,739 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 1.3M times each, and 0.753% of those impressions turn into an interaction. That is about 3.06% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.8 posts a day over the last 30 days, with activity on roughly 73% of days. Most posts go out around 16:00 UTC, and Tuesday is the busiest day of the week. Of the 68 posts sampled, 63% carry an image or video, 9% are part of a thread and 34% link out. The account's strongest tracked post pulled 159K interactions, about 16x its own typical post.

Compared with accounts its own size
SpaceX's engagement rate beats 60% of the tracked X accounts closest to it in follower count (3,739 accounts, accounts of similar size (decile 10 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 49% 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 0.023%, SpaceX sits above the 25th percentile of the 36,261 accounts in this comparison. That places it in the below the median band, which runs 0.012% to 0.08%.

Posting timing
This account posts most often around 16:00 UTC, and Tuesday 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.

Terafab will be built in Grimes County, Texas In April, we broke ground on our research fab on the North Campus of Giga Texas – the precursor to Terafab. Both Tesla & SpaceX will need far more chips than current & future global production can supply. This is why we're building the largest chip manufacturing facility ever, with the goal of producing over 1 terawatt of compute per year The future is built in Texas https://t.co/RQPNlAasdP

View of Starship in space from a Starlink V3 satellite on Flight 13. This composite is made of imagery from four separate cameras on a single satellite. Six of the satellites were equipped with cameras to scan Starship’s heat shield and transmit imagery down to operators to continue testing methods of analyzing Starship’s heat shield readiness for return to launch site on future missions

Reading these numbers
A typical post picks up 9.6K interactions against 42M followers, an engagement rate of 0.023%. Measured over 68 original posts, its engagement rate beats 60% of 3,739 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 1.3M times each, and 0.753% of those impressions turn into an interaction. That is about 3.06% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.8 posts a day over the last 30 days, with activity on roughly 73% of days. Most posts go out around 16:00 UTC, and Tuesday is the busiest day of the week. Of the 68 posts sampled, 63% carry an image or video, 9% are part of a thread and 34% link out. The account's strongest tracked post pulled 159K interactions, about 16x its own typical post.
- What is SpaceX's engagement rate on X?
- SpaceX (@SpaceX) has an engagement rate of 0.023%, based on the median interactions across 68 original posts from the last 30 days against 41,900,661 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.023%, SpaceX sits above the 25th percentile of the 36,261 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 @SpaceX have real engagement?
- Its engagement rate beats 60% of the tracked X accounts closest to it in follower count (3,739 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 @SpaceX post?
- Most posts go out around 16:00 UTC, and Tuesday is its busiest day, at roughly 2.83 posts per day across the measured window.
