Bluesky in Mid-2026: Mobile Users Halved as CEO Toni Schneider Bets Everything on the AT Protocol

Bluesky was the toast of the social media world in late 2024, riding a massive wave of users fleeing X after the U.S. election. By mid-2026, the picture has dramatically changed: the mobile app has lost over half its peak active users, and the company has a new CEO executing a radical strategic pivot from the app to the underlying AT Protocol. Here's a comprehensive look at the numbers, the reasons behind the decline, and Bluesky's bet on becoming the open infrastructure for the social web.

User Engagement: A Sharp Decline from a Post-Election Spike

Bluesky's mobile app has seen a sustained pullback from the surge it experienced around the US 2024 election. The user engagement metrics from Similarweb, reported by multiple outlets in August 2026, paint a stark picture .

• Monthly Active Users (MAU): The mobile app had 10.4 million MAUs globally in June 2026, down 27.2% year-over-year . The Q2 2026 quarterly average was 10.7 million, a devastating 52% drop from the all-time peak of 22.1 million in Q4 2024 .
• Daily Active Users (DAU): Mobile DAUs fell 25.6% year-over-year in July 2026 to approximately 3 million . This decline was underway even earlier; the DAU figure was down 40% year-over-year by October 2025 .
• Total Registered Accounts vs. Active Usage: Bluesky's overall registered user base still grew in 2025, reaching 41.4 million total accounts by year-end, a nearly 60% increase . But active engagement on the mobile app contracted sharply, meaning many new signups from the 2024 wave did not become regular users . This divergence between total signups and daily engagement is a key sign of waning user retention .

Why Users Dropped Off

Several factors explain the post-peak decline, none of which are a single cause but rather a combination of external pressure and internal strategic choices .

• Event-driven surge exhaustion. The Q4 2024 spike was largely a one-time migration of users unhappy with X after the US election. A significant portion of those new users did not stick around once the news cycle cooled .
• Competition from Threads. Meta's Threads has grown steadily, pulling attention—especially from casual social media users—and making it harder for Bluesky to retain its less-engaged cohort .
• Strategic deprioritization of the app itself. Bluesky's leadership has openly shifted focus from growing the main Bluesky app to building the AT Protocol ecosystem, which signals to users and the market that the flagship app is no longer the company's sole priority .

Strategy Shift: From App to Protocol

Bluesky's new CEO Toni Schneider (appointed permanent CEO in July 2026 after serving as interim since March) is leading a deliberate and openly stated pivot . Schneider, the former CEO of Automattic, has laid out a "decade-long vision" that de-emphasizes competing directly with X and Threads as a single app and instead focuses on becoming the open infrastructure for a federated social web .

Key strategic moves under Schneider:

• AT Protocol as the centerpiece. Schneider's core goal is to make the AT Protocol the open infrastructure for a federated social web, not just to run Bluesky's own app. He has stated the 10-year ambition is for 1 billion people to use the AT Protocol . The protocol spec has been submitted to the IETF as an official standards track, and SDK downloads have tripled .
• Ecosystem of Independent Apps (The Atmosphere). Bluesky is now positioning itself as one app within the broader "Atmosphere" ecosystem—a thriving network of over a thousand interoperable apps and services running on the AT Protocol . Key projects include:
  • BlackSky — An independent AT Protocol social network built by a separate team (BlackSky Algorithms) using a Rust-based implementation called "rsky." It interoperates with Bluesky's network but runs its own independent infrastructure, including its own relay, demonstrating true decentralization .
  • Eurosky — A project focused on building European infrastructure for the open social web atop the AT Protocol. It aims to provide a GDPR-compliant, Europe-governed identity for users, giving them an alternative to US-controlled platforms .
  • Skylight — A video-focused AT Protocol app that has already attracted around 380,000 users .
  • Flashes — A photo-focused app (often described as an Instagram alternative) that uses the same AT Protocol and allows users to bring their social graph with them .
• New Products and Features:
  • Attie — An AI assistant app launched in March 2026 that lets users design custom algorithms, build custom feeds, and eventually "vibe-code" their own apps using Anthropic's Claude under the hood .
  • Private data and community support. Bluesky has shipped a "permissioned data spec" (allowing private/closed data on the open protocol), group chats, and a roadmap for private communities and smaller social spaces—the thing Schneider cited as likely to "unlock the next wave of growth" .
• Funding and Business Model: Bluesky secured a $100 million Series B round in July 2026, led by Alumni Ventures, True Ventures, Anthos Capital, Bloomberg Beta, and the Knight Foundation . To become self-sustaining, Bluesky plans to launch monetization this year using an affiliate-style revenue sharing model rather than traditional advertising .

Note on X and Threads contrasting performance: Reports consistently note that Meta's Threads continued to grow its active user base during this period, while Bluesky has fallen behind both X and Threads in daily active usage .

The Core Tradeoff

Bluesky is knowingly trading short-term app-user metrics for long-term protocol adoption. Schneider has framed the mobile MAU decline as an acceptable cost of building a wider "Atmosphere" ecosystem, arguing that Bluesky's ultimate success will be measured by the number of people using AT Protocol-powered services—not just the Bluesky app . Whether that bet pays off will depend on whether projects like BlackSky, Eurosky, Skylight, and Attie can attract and retain users at scale, and whether the developer community embraces the protocol as the go-to open standard for social media.
