The decentralized social network Bluesky, once hailed as a significant beneficiary of user discontent with Elon Musk’s X following the U.S. elections in November 2024, is now grappling with a notable decline in its user engagement. Nearly two years after this initial surge, the platform, positioned as a potential competitor to X, is struggling to sustain its momentum, with key metrics indicating a significant year-over-year drop in active users.
According to comprehensive data compiled by digital intelligence provider Similarweb, Bluesky’s mobile application registered 10.4 million monthly active users globally in June 2026, marking a substantial decrease of 27.2% compared to the same period in the previous year. This downward trend extends to daily active users as well. In July 2026, the number of mobile daily active users continued its descent, falling by 25.6% year-over-year to approximately 3 million. These figures suggest a concerning pattern where, despite the potential for continued account registrations, a shrinking proportion of users are engaging with the platform on a regular basis via its mobile app. The data also strongly implies that a segment of the users who joined Bluesky out of dissatisfaction with X in the immediate aftermath of the 2024 elections have not remained long-term users.
The broader narrative emerging from these statistics is not merely a contraction of Bluesky’s post-election boom. A more significant concern is the platform’s sustained decline in app usage. Bluesky’s mobile app has shed over half of its monthly active users from its peak in late 2024. At its zenith, the platform recorded a quarterly average of approximately 22.1 million monthly active users in the fourth quarter of 2024. By the second quarter of 2026, this figure had dwindled to 10.7 million, representing a stark decline of around 52%. This substantial decrease indicates that even after the initial wave of post-election users subsided, Bluesky’s app usage continued to contract, suggesting underlying challenges in retaining its user base.
The Genesis of the Bluesky Surge
The November 2024 U.S. elections served as a pivotal moment for many social media platforms. Amidst heightened political discourse and concerns about content moderation and platform policies on X, a notable segment of users began seeking alternatives. Bluesky, with its promise of a decentralized, open-source social networking protocol (AT Protocol), emerged as a compelling option for those disillusioned with the prevailing social media landscape. The platform’s architecture, designed to foster greater user control and interoperability, resonated with a growing audience wary of centralized control and algorithmic manipulation.
This exodus from X saw Bluesky experience an unprecedented surge in sign-ups and user activity. Early adopters praised its clean interface, emphasis on chronological feeds, and a perceived more civil discourse compared to its larger counterparts. The platform’s development, initially incubated by Twitter but later spun off into an independent entity, was closely watched. The influx of users during this period presented Bluesky with a significant opportunity to establish itself as a viable alternative and a serious contender in the social media arena. However, as the initial excitement waned and the political landscape shifted, the challenge of long-term user retention became acutely apparent.
Sustaining Engagement: The Stickiness Factor
Despite the overall decline in active users, the data from Similarweb also offers a glimmer of hope, indicating that the users who have remained on Bluesky are demonstrably committed. In June 2026, the platform maintained a "stickiness rate" – the ratio of daily active users to monthly active users – of approximately 29%. This figure is noteworthy as it aligns with the stickiness rate observed on Meta’s Threads, another prominent competitor in the social media space. This suggests that while the total user base may be smaller, the core community on Bluesky exhibits a consistent level of engagement.
For Bluesky’s new CEO, Toni Schneider, who assumed the role of interim CEO and later transitioned to a permanent position, these engagement metrics may not necessarily be viewed as a crisis. The company’s strategic vision appears to extend beyond the singular success of the Bluesky application itself. Instead, the overarching objective is to foster the widespread adoption and utility of the underlying AT Protocol. This protocol is intended to serve as the foundational technology for a diverse ecosystem of social applications, services, and communities, moving beyond the confines of a single platform.
Building Beyond the App: The AT Protocol Ecosystem
The company’s long-term strategy hinges on the success of the AT Protocol as a versatile and extensible framework for decentralized social networking. This vision is beginning to manifest with the emergence of new projects built upon AT Proto. Platforms such as BlackSky and Eurosky are reportedly experiencing growth, indicating the protocol’s capability to support various niche communities and applications. Furthermore, video-focused applications like Skylight have demonstrated early traction, attracting a significant user base after the finalization of a major deal involving TikTok in the U.S. This suggests that the AT Protocol can indeed power diverse content formats and user experiences.
Bluesky has also been actively developing new products and features to enhance its ecosystem and attract a broader range of users. The recent launch of Attie, an AI-powered research tool, signifies an expansion into more specialized functionalities. Attie is designed to serve as an open social research platform, potentially offering new avenues for data analysis and community insights. Looking ahead, Bluesky is reportedly working on integrating support for private data within its platform. This development could be a significant catalyst for attracting a different demographic of users – those who are less inclined towards the public discourse of a traditional social media "town square" and more interested in private networking, encrypted communications, and exclusive communities. This move towards private data support could unlock new revenue streams and user acquisition channels, differentiating Bluesky from its more public-facing competitors.
Shifting User Flows and Competitive Landscape
Crucially, the declining user numbers on Bluesky do not necessarily indicate a mass return to X. Similarweb’s data reveals a more nuanced picture of the competitive landscape. In June 2026, X’s worldwide monthly active users on mobile saw a modest decline of approximately 3% year-over-year. In July, X’s mobile daily active users dropped by 7% to 123.7 million. While X remains a dominant force with around 302 million monthly active users on its app as of June 2026 and a growing number of web visits, its overall growth trajectory appears to be moderating. This suggests that the users leaving Bluesky are not predominantly migrating back to X.
The platform that appears to be gaining significant ground is Threads. It remains an open question whether Threads is directly benefiting from Bluesky’s disengagement, or if it is attracting a new cohort of users who have never previously engaged with Twitter-like services. Regardless of the exact dynamics, Meta-owned Threads has experienced remarkable growth. In July 2026, its daily active users surged by 21.3% year-over-year to 147 million. Concurrently, its website visits saw an explosive increase of 112% year-over-year, reaching 471.6 million. This rapid expansion positions Threads as a formidable contender, potentially absorbing users from various social media platforms seeking dynamic engagement and community interaction.
Bluesky’s Public Presence and Future Outlook
While Bluesky’s internal metrics for daily and monthly active users are not publicly disclosed, the company does provide statistics on registered users. According to its own public data, Bluesky has amassed nearly 46 million registered users. This figure, when contrasted with the Similarweb data on active users, underscores the challenge of converting registered accounts into consistent daily or monthly engagement. The platform’s own public statistics, available via its developer portal, highlight the growth in registered accounts, but the absence of detailed active usage data leaves room for interpretation regarding the true health of its user base.
The trajectory of Bluesky presents a compelling case study in the volatile nature of the social media landscape. Its initial surge, fueled by external events and user dissatisfaction with a dominant platform, demonstrated the potential for disruption. However, the subsequent decline in active users highlights the persistent challenge of sustained growth and retention in a highly competitive market. The company’s strategic pivot towards developing the AT Protocol as a foundational technology, rather than solely focusing on the Bluesky app, suggests a long-term vision aimed at building an interconnected ecosystem. The success of this strategy will depend on its ability to foster innovation within the AT Protocol community, attract developers, and ultimately deliver compelling user experiences across a variety of decentralized applications. As Bluesky navigates these challenges, its ability to foster meaningful engagement and demonstrate the tangible benefits of its decentralized approach will be critical in determining its future impact on the social media paradigm. The coming years will reveal whether the AT Protocol can truly empower a new generation of social networking, or if Bluesky will remain a cautionary tale of a promising platform that struggled to convert initial hype into enduring user loyalty.
