The acquisition combines SpaceX's rocket capabilities with xAI's technology to create what Musk in the statement called "the most ambitious, vertically-integrated innovation engine on (and off) Earth."

The merger comes as funding for the AI buildout embraced by big tech companies begins to show signs of tension.

Musk said SpaceX plans to launch a constellation of satellites that would function as orbital data centers, harnessing solar power in space to meet growing electricity demands for AI computing.

Musk said those needs cannot be met on Earth "without imposing hardship on communities and the environment."

"By directly harnessing near-constant solar power with little operating or maintenance costs, these satellites will transform our ability to scale compute," Musk wrote in the announcement.

SpaceX aims to launch one million satellites operating as data centers using its Starship rocket, which the company said will soon achieve launch rates of one flight per hour carrying 200 tons of payload.

The announcement did not disclose financial terms of the acquisition or provide a timeline for initial satellite deployments.

According to Bloomberg, the combined company would have a valuation of $1.25 trillion.

The deal further intertwines Musk's sprawling business empire, which already includes carmaker Tesla and social media platform X, formerly Twitter.

Musk merged X with xAI after acquiring Twitter in late 2022.

xAI, which operates the Grok chatbot, was valued at $230 billion in a January funding round.

The combined company would pool capital, computing resources and talent as Musk pursues his vision of placing data centers in space for AI computing.

SpaceX is reportedly targeting a mid-June initial public offering that could raise as much as $50 billion, according to US media.

The company dominates the space launch market with its reusable rockets and owns the largest satellite constellation through Starlink.

Musk had previously opposed an IPO for SpaceX because he had not enjoyed the required scrutiny of publicly traded Tesla.

He also argued that the market's desire for financial returns was at odds with his ultimate goal of settling Mars.

But the company's latest priorities will require significant investment.

These include developing Starship, the largest rocket ever built, for missions to the Moon and Mars.

Indonesia says it will restore access to Musk's Grok chatbot
Jakarta (AFP) Feb 1, 2026 - Indonesia will restore access to Elon Musk's AI chatbot Grok after the billionaire's social media platform X promised to comply with the country's laws, a government official said on Sunday.

Grok has faced a global backlash after it emerged that its image creation feature allowed users to sexualise pictures of women and children using simple text prompts.

Malaysia and the Philippines followed Indonesia in temporarily blocking access to the tool, which is integrated into X, over concerns about AI-generated sexual deepfakes.

Alexander Sabar, a senior official in Indonesia's communication and digital ministry, said access was being restored "conditionally" after X Corp gave "a written commitment containing concrete steps for service improvement and prevention of misuse".

Sabar said in a statement the ministry would continue to supervise and evaluate Grok and that it would take "corrective actions", including another suspension, if violations were found.

xAI, the Musk-owned startup that developed the AI tool, did not respond immediately to AFP's request for comment.

However, it told the Philippines last month that it would modify Grok to suit the local market, including the "total exclusion of pornographic content, particularly child sexual abuse material".

Malaysia also restored access to Grok after receiving similar promises from X that included "additional preventive and security measures".

The EU said in late January it had opened an investigation into Grok's sexualised deepfake images of women and minors.

Grok said in response it was restricting image generation and editing to paying subscribers.
