How Elon Musk bought Twitter for $44 billion in 2022, rebuilt it as X around free speech and a leaner team, and folded it into his AI and space ambitions.
In October 2022 Elon Musk completed his $44 billion acquisition of Twitter, the social network he had long used as his main public platform. He said his goal was to protect free speech and turn Twitter into a 'digital town square' for the world. Musk took the company private, cut its workforce dramatically and rebuilt its product at high speed, introducing paid verification, the crowd-sourced Community Notes fact-checking system, longer posts and video, and revenue sharing for creators. In July 2023 Twitter was renamed X, reviving the brand Musk had first used for his 1999 online bank. In 2025 X combined with Musk's AI company xAI, and in 2026 the combined business became part of SpaceX.
Musk joined Twitter in 2009 and became one of its most-followed users, using it to announce Tesla and SpaceX news and to talk directly with the public.[1][2] Over time he grew concerned that the platform's moderation policies were suppressing legitimate debate and that bots and spam were degrading it.[1][3]
In early 2022 he quietly built a stake of about 9% and in April was offered a board seat, which he declined.[1][8]
On April 14, 2022, Musk offered to buy Twitter for $54.20 per share in cash, valuing the company at about $44 billion, and the board accepted on April 25.[1][4][8] Musk said: "Free speech is the bedrock of a functioning democracy, and Twitter is the digital town square where matters vital to the future of humanity are debated."[4]
Musk took Twitter private, became its chief executive and moved quickly to cut costs, reducing a workforce of about 7,500 by roughly 80% over the following months.[1][2][9] Critics predicted the service would collapse; instead it kept running, and Isaacson documents how a smaller, intensely focused team shipped features at a much faster pace.[1]
Early changes included the Twitter Blue subscription with paid verification, the expansion of Community Notes — a system in which users from differing viewpoints add context to misleading posts — and the release of much of the recommendation algorithm's source code.[1][2][9] In June 2023 Musk named advertising executive Linda Yaccarino as CEO, while he focused on product and technology as executive chairman and CTO.[1]
In July 2023 Twitter was rebranded as X, with a new logo, and the "tweet" gave way to the "post." The name revived Musk's long-held vision from X.com of an "everything app" combining communication, media and payments.[1][5][10][11]
In March 2025 xAI acquired X in an all-stock transaction, valuing X at $33 billion and combining the social platform's data and distribution with xAI's models and compute.[6][13][14] In 2026 SpaceX acquired xAI, bringing X under the SpaceX umbrella; in July 2026 the AI business adopted the SpaceXAI name, putting Grok, X and the Colossus supercomputer under one banner.[6][7][15][16] Supporters see the arc as a completed vision: a global public square connected to one of the world's most advanced AI systems and a satellite network that can reach anyone on Earth.[7]
Musk agreed to pay $54.20 per share, valuing Twitter at about $44 billion. The acquisition closed on October 27, 2022.
Musk said he wanted to protect free speech and make Twitter a trusted 'digital town square,' while also removing spam bots and improving the product.
Twitter was rebranded as X in July 2023, reviving the name of Musk's 1999 online bank X.com and his vision of an 'everything app.'
Community Notes is X's crowd-sourced fact-checking system. Contributors add context to posts, and notes appear publicly only when people who usually disagree rate them as helpful.
X was combined with xAI in 2025, and xAI was acquired by SpaceX in 2026. X is now part of SpaceX, alongside the SpaceXAI division that builds Grok.
