Bluesky crossed 43.5 million registered accounts in April 2026. That is the headline number, and it is the one that will appear in most coverage. It is also the least useful number for almost any decision you might be making.
Here is the fuller picture, updated from our March 2026 MAU report.
April 2026 at a Glance
| Metric | April 2026 | Change from March |
|---|---|---|
| Registered accounts | ~43.5 million | +~1.5 million |
| Monthly active users (estimate range) | 12–27 million | Roughly flat |
| Daily active users (estimate range) | 1.5–3 million | Roughly flat |
| DAU as % of registered | ~8–9% | Slightly down |
The Registration Number Keeps Climbing
Bluesky has added roughly 1.5 million registered accounts per month through the first third of 2026. From the 41.41 million the platform reported at the end of 2025, that puts April at approximately 43.5 million.
Consistent monthly growth of 1.5 million is genuinely healthy. It is also considerably slower than the 5-million-per-month peaks of the 2024 migration waves, and the composition has changed: fewer bulk arrivals from a single news event, more steady organic signup.
The Engagement Number Is Not Climbing
This is the part that matters and the part that headlines skip.
Daily active users peaked at roughly 4.1 million in June 2025. Mobile DAU then fell about 40% year over year through late 2025, bottoming near 3.5 million in October. Estimates through early 2026 put DAU somewhere in the 1.5 to 3 million range depending on whose panel you trust and whether web usage is counted.
So the two curves have decoupled. Registrations up and to the right; daily engagement flat to down. Every month that continues, the ratio between "users" and "people who will actually see your post" gets worse.
Why this happens
- Migration waves recruit tourists. A news event drives a million signups; most of them post twice and leave. The account stays on the ledger forever.
- Bots and automation. An open protocol with free registration accumulates automated accounts. They inflate registration counts and, depending on methodology, MAU too.
- No strong retention hook. Bluesky's Discover feed has historically underperformed the algorithmic feeds users are habituated to elsewhere – which is precisely why fixing it was the headline item on the platform's 2026 roadmap.
The Roadmap Bet
Bluesky's published 2026 plans are aimed almost entirely at this problem rather than at acquisition. The priorities:
- A substantially better Discover feed and improved follow recommendations – the core retention lever
- Real-time and "live moments" – making the platform the place to be during breaking news, sports and elections
- Core feature catch-up – post drafts, faster and longer video, more than four images per post
- Custom feed visibility – giving good curation a real distribution surface
That is a coherent read of the problem. Acquisition is not Bluesky's weak point; habit formation is. Whether it works will show up in DAU, not in the registration counter.
What to Do With These Numbers
For brands and creators
Model your reachable audience against DAU, not registrations. A realistic ceiling is a few million daily actives, heavily concentrated in the US, Japan, Brazil, the UK and Germany, skewing young and technical. That is a real audience – it is just not "43 million people."
For developers
Firehose volume follows activity. If you are sizing a service, model against posting rates. Our firehose guide has real throughput numbers and our rate limits guide covers what the API will actually let you do.
For anyone quoting the number
Say which metric you mean. "43.5 million registered accounts" is accurate. "43.5 million users" is not, in any sense a marketer would recognize.
Frequently Asked Questions
Does Bluesky publish MAU?
No. Registration totals and transparency reports only. Every MAU figure in circulation is a third-party estimate, and they disagree by more than 2x.
Why is the DAU range so wide?
Mobile analytics panels miss browser and third-party client usage. Network-side counts include bots. Neither is wrong; they measure different populations.
Is Bluesky dying?
No – it is adding 1.5 million accounts a month and has a stable core of a few million daily users. But it is not growing engagement, which is a real and acknowledged problem the platform is spending its 2026 roadmap on.
