Elon Musk says xAI has acquired X, the social media platform formerly known as Twitter, in an all-stock transaction. The deal ties one of Musk’s most visible consumer platforms directly to his artificial intelligence startup.
In his post on X Friday, Musk said, “xAI has acquired X in an all-stock transaction.” He added that “The combination values xAI at $80 billion and X at $33 billion ($45B less $12B debt).”
The deal brings two Musk companies together
The acquisition places X under the umbrella of xAI, the AI startup Musk founded in 2023 to compete with OpenAI. X had already been closely connected to xAI’s products, including the chatbot Grok, but the transaction makes the relationship more formal.
Musk described the future of the two companies as “intertwined.” He also said, “Today, we officially take the step to combine the data, models, compute, distribution and talent.”
That short list explains why the transaction matters. X gives xAI a major consumer platform, while xAI brings AI models and infrastructure into closer alignment with X. The result is a combined operation built around both social distribution and artificial intelligence development.
Valuations show how much is at stake
Musk said the transaction values xAI at $80 billion and X at $33 billion. The X figure reflects a $45B enterprise value reduced by $12B debt, according to Musk’s post.
Those numbers stand out because X’s valuation has changed sharply since Musk purchased the platform for $44 billion in October 2022 and took it private. At one point, Fidelity valued X at less than $10 billion.
The source article says X’s valuation has risen in the months since the inauguration of President Donald Trump, for whom Musk aggressively campaigned and for whom Musk now serves under as a special adviser leading DOGE. The reason given is that investors believe the platform is more influential now.
Musk also said X has more than 600 million active users. For an AI company, that kind of distribution can matter as much as technical infrastructure, because it creates a direct path to people who may use or encounter AI products inside a familiar app.
A new holding company is expected
According to publications including The Wall Street Journal, shares of X and xAI will be exchanged for shares of a new holding company called xAI Holdings Corp. The Wall Street Journal also reports that executives at both companies believed it would be easier to raise money for a combined entity.
That financing logic fits the broader picture described in the source article. xAI has been trying to catch up with other frontier AI developers, and that effort requires researchers, data centers, models and capital.
Musk launched xAI in 2023 and has added AI researchers from Google DeepMind, Microsoft, and OpenAI. The company has also built out the massive AI data centers needed to compete with other frontier AI developers.
In December, xAI raised $6 billion in a funding round that valued the startup at $45 billion. According to Musk, xAI’s valuation is now $80 billion.
Grok and X are now even more closely linked
xAI’s products were already integrated into X before the acquisition. Grok, xAI’s AI chatbot, has been one of the clearest examples of that connection.
In February, xAI released Grok 3, described in the source article as a frontier AI model that is competitive with leading AI models on benchmarks measuring math, science, and coding. The acquisition gives that AI work a larger and more direct connection to X’s user base.
The source article identifies X as one of xAI’s major advantages over OpenAI and other startups. The platform has accumulated a large body of posts over the years, giving xAI a significant advantage in the race for AI training data.
X also gives xAI a consumer app for reaching users. That combination helps explain why the platform’s value may extend beyond advertising or social media influence. In Musk’s AI strategy, X can serve as data source, distribution channel and product surface at the same time.
The OpenAI rivalry remains part of the backdrop
The acquisition comes as Musk continues to challenge OpenAI, a startup he co-founded with Sam Altman. The source article says Musk is trying to thwart OpenAI’s for-profit transition, which OpenAI needs to complete to secure future funding.
That effort includes Musk’s lawsuit against OpenAI, where OpenAI’s for-profit transition is described as the centerpiece. Musk also submitted a $97 billion takeover bid for Altman’s startup in February.
OpenAI’s board rejected that bid, but the source article says it may already have driven up the market price for OpenAI’s assets. Against that backdrop, combining xAI and X sharpens the competition between Musk’s AI ambitions and the companies he is trying to catch.
Musk also leads Tesla, SpaceX, and Neuralink, and the source article notes that he has a history of blurring the lines between his companies, which has landed him in legal trouble before. With xAI acquiring X, the two companies are now effectively one, and X’s role in Musk’s broader AI plans is clearer than ever.
