Bluesky Reaches 1 Million Accounts
Bluesky, the decentralized social network launched by Twitter founder Jack Dorsey, has surpassed 1 million registered users. The platform remains invite-only but plans to open to more users soon. Bluesky reports 2–3 million additional potential users on its waiting list. After open-sourcing the app in May 2023 and releasing a paid version in July 2023, Bluesky is accelerating growth and preparing for broader access. The Bluesky team says the next phase focuses on enabling more users by enhancing moderation and curation through expanded staffing and tooling, scaling the infrastructure, and federating the network to support growth, while iterating on the app experience. The development is framed against the backdrop of ongoing friction on X, which Bluesky could serve as an alternative to for users seeking a different experience.
Moderate industry relevance due to open sourcing and growth of Bluesky as a decentralized platform.

Bluesky: Super Bowl spike and drafts rollout
Bluesky, an open social network, continues to grow but remains smaller than rivals. In 2025 Bluesky’s user base rose from 25 million to 42 million, while Threads reportedly surpasses 400 million monthly active users. Growth is aided by high-profile accounts and events, including media outlets and figures such as Alexandria Ocasio-Cortez, Stephen King, and the New York Times, plus major events like the Super Bowl with Bad Bunny, which boosted Bluesky activity by about 70% during the game. The platform also rolled out version v1.116, introducing a Drafts feature in the Post Composer to create and save posts for later. A welcome-screen refresh accompanied the release, featuring artwork by @odpomery.bsky.social with light and dark theme variants.
Bluesky pivots toward Reddit-style community model
Bluesky, the social network that originated inside Twitter, is shifting its strategy away from trying to mirror X or Threads and toward community-driven, Reddit-style spaces, Bluesky COO Rose Wang told CNBC at SXSW London. The platform, built on the open-source AT Protocol, has significantly fewer users and lower engagement than X — roughly 43 million global users as of March and about 10% of X’s estimated global audience. Bluesky raised $100 million in a Series B in April 2025, but daily active posters reportedly fell from a late-2024 peak of 1.4 million to roughly 600,000. Wang said Bluesky will prioritise discovery and community features and needs to modernize video capabilities (upload speeds and longer video length). The company has not ruled out advertising, though it does not view ads as a foregone conclusion.
