The Boston startup uses AI to translate and verify legacy software for defense contractors, arguing modernization can't come at the cost of new bugs. Code Metal, a Boston-based startup that uses AI to write code and translate it into other programming languages, just closed a $125 million Series B funding round from new and existing investors. The news comes just a few months after the startup raised $36 million in series A financing led by Accel. Code Metal is part of a new wave of startups aiming to modernize the tech industry by using AI to generate code and translate it across programming languages. One of the questions that persists about AI-assisted code, though, is whether the output is any good--and what the consequences might be if it's not.

The Morning After: Elon Musk's SpaceX is buying his AI company, xAI Like some sort of corporate Russian doll, SpaceX has announced its acquisition of xAI. The merger will "form the most ambitious, vertically integrated innovation engine on (and off) Earth," according to, well, owner Elon Musk. The AI company, arguably best known for its ongoing CSAM-generating chatbot controversy, might seem like a strange fit for a rocket company. But SpaceX is apparently key to Musk's latest scheme to build AI data centers in space. There might be an argument for moving the resource-intensive operations to space -- but Musk continued.

Elon Musk's SpaceX has acquired his AI company xAI as part of an ambitious scheme to build space-based data centres to power the future of artificial intelligence. The billionaire, who is also the CEO of Tesla, announced the merger in a statement on Tuesday on the SpaceX website. AI demand will require "immense amounts of power and cooling" that are not sustainable on Earth without "imposing hardship on communities and the environment," he said. Space-based data centres that harness the power of the Sun are the only long-term solution, according to Musk. "In the long term, space-based AI is obviously the only way to scale. To harness even a millionth of our Sun's energy would require over a million times more energy than our civilisation currently uses!" he wrote.

Elon Musk's SpaceX is taking over his artificial intelligence (AI) start-up, as the billionaire continues to unify some of his many business interests. SpaceX confirmed the deal to acquire xAI, a smaller firm known for its Grok chatbot, posting a memo from Musk about the merger on its website. In the note, Musk said the combination would form an innovation engine putting AI, rockets, space-based internet, and media under one roof. Terms of the deal were not disclosed. However, a source familiar said it valued xAI at $125bn (£91bn) and SpaceX at $1tn, making it the most valuable private company ever.

Last year, Musk's AI company bought his social media company, X. CANADA - 2026/01/31: In this photo illustration, the SpaceX (Space Exploration Technologies Corp - Space X) logo is seen displayed on a smartphone screen. The merger will "form the most ambitious, vertically-integrated innovation engine on (and off) Earth, with AI, rockets, space-based internet, direct-to-mobile device communications and the world's foremost real-time information and free speech platform," Musk wrote in an update. The AI company that right now is best known for its CSAM-generating chatbot might seem like a strange fit for a rocket company. But SpaceX is key to Musk's latest scheme to build AI data centers in space. In his update, Musk wrote that "global electricity demand for AI simply cannot be met with terrestrial solutions" and that moving the resource-intensive operations to space is "the only logical solution."

Musk's SpaceX in merger talks with xAI ahead of planned IPO, source says SpaceX combining with xAI would bring Elon Musk's rockets, Starlink satellites, the X social media platform and Grok AI chatbot under one roof. NEW YORK - Elon Musk's SpaceX and xAI are in discussions to merge ahead of a blockbuster public offering planned for later this year. The combination would bring Musk's rockets, Starlink satellites, the X social media platform and Grok AI chatbot under one roof, according to a person briefed on the matter and two recent company filings. The plan, which Reuters is reporting exclusively, would give fresh momentum to SpaceX's effort to launch data centers into orbit as Musk battles for supremacy in the rapidly escalating artificial intelligence race against tech giants like Google, Meta and OpenAI. Musk, the world's richest man, is the CEO of both the private space company SpaceX and the artificial intelligence company xAI, which controls his social media platform X.

SpaceX combining with xAI would bring Elon Musk's rockets, Starlink satellites, the X social media platform and Grok AI chatbot under one roof. NEW YORK - SpaceX is exploring deals with other companies helmed by serial entrepreneur Elon Musk, leaving investors working through permutations between space, autonomous driving and artificial intelligence to analyze which combination makes the most sense. The rocket maker is in discussions to merge with xAI ahead of a blockbuster public offering planned for this year, Reuters reported on Thursday. The combination would bring Musk's rockets, Starlink satellites, X social media platform and Grok chatbot under one roof, according to a person briefed on the matter and two regulatory filings. The deal's value, timing or primary rationale could not be independently determined.

It follows reports that SpaceX is planning an IPO as early as this year. Two Elon Musk companies are reportedly planning to merge. On Thursday, reported that SpaceX and xAI are holding merger talks ahead of a planned IPO. Part of their plan is to launch AI data centers into space (but unfortunately, only as far as Earth's orbit). Last week, it was reported that Musk planned to take SpaceX public despite having once said it wouldn't happen until the company had a presence on Mars.
