Bluesky has jumped to 40 million users, driven by spikes from events. Learn how its decentralized model and audience profile affect brand strategy.
Bluesky, the decentralized social network built on the AT Protocol, has surged to roughly 40 million users, a growth spurt that began after its public launch in early 2024 and accelerated through cultural and geopolitical events [2]. The platform’s unique architecture lets users move their social graph across apps, positioning it as both a standalone service and an emerging infrastructure for future social experiences [1].
Key takeaways
Bluesky opened to the public in February 2024 after an invite‑only phase, attracting nearly 800 000 new users in a single day [2]. Subsequent spikes were tied to external events: Brazil’s temporary ban on X in September 2024 drove 2.6 million sign‑ups in a week, and the U.S. presidential election in November 2024 lifted the user count from 15 million to 22.5 million within twelve days [2]. By August 2025 the platform reached 38 million users, stabilizing growth at roughly 1.6 million per month, and by November 2025 it topped 40.2 million [2].
These surges reflect a broader desire for spaces where participants can control their data and community standards. Bluesky’s AT Protocol, an open technical standard, allows posts and followers to migrate across apps without losing the social graph, distinguishing it from “walled‑garden” networks where a single company controls servers and data [1]. CEO Jay Graber describes Bluesky as a “collective organism” that could outlive any single app built on the protocol [1].
Jay Graber, who became CEO after joining the project in 2021, insisted that Bluesky remain legally independent from Twitter—a condition that proved prescient when Twitter’s ownership changed in 2022 and the service agreement was cancelled [1]. Under Graber’s “high agency, low ego” philosophy, a small team of about 30 employees operates without a formal headquarters, collaborating from a Seattle co‑working space [1]. This decentralized internal structure mirrors the platform’s external ethos, encouraging users to shape their own communities rather than conform to a monolithic algorithm [1].
For brands, Bluesky presents a niche but highly engaged audience, with average session times of over ten minutes indicating active participation rather than passive scrolling [2]. The platform’s community‑driven discovery model—relying on custom feeds instead of hashtags—means that traditional mass‑reach tactics may be less effective, while targeted, value‑adding content could resonate strongly [2]. As Bluesky continues to expand, especially in the U.S., Japan, and Brazil, marketers must decide whether to allocate resources to this emerging decentralized space or focus on established platforms with broader reach. The network’s growth trajectory suggests that user interest in decentralized social experiences is rising, and brands that experiment early may gain a foothold in a potentially enduring infrastructure [1][2].

Group chats are currently limited to 50 participants and do not yet support media sharing due to ongoing development of safety and moderation systems.
Communities will be smaller, interest-based spaces within the platform that feature their own handles, which serve as URLs, and can be set to public, invite-only, or private.
The shift is a strategic response to growth challenges, aiming to offer a different value proposition by providing user-owned spaces where moderation is handled by the community rather than the platform.
