Elon Musk attends Donald Trump's inauguration in Washington DC on 20 January 2025. Sam Altman attends a press conference at the White House on 21 January 2025. Musk and Altman's AI rivalry reaches boiling point as IPO race heats up Let's recap a whirlwind five days that may determine the future of AI.

Tech billionaire Elon Musk's SpaceX is preparing to list its shares on the US-based Nasdaq in what will be the most hotly anticipated initial public offering (IPO) in years. Here's everything you need to know about the deal: Founded in 2002 by Musk, now the world's richest man, SpaceX is best known for designing and launching rockets, spacecraft and reusable launch vehicles. Since 2006, the company has partnered with NASA to deliver cargo and crew to the International Space Station (ISS). The Texas-based company has also launched rockets, satellites and spacecraft for various private companies. As well as its aerospace business, SpaceX provides internet services and artificial intelligence platforms through its dedicated divisions, Starlink and xAI.

Elon Musk's SpaceX has revealed its plans to go public in the US, allowing people to trade shares in the firm on the stock market. SpaceX makes rockets, offers a satellite internet service called Starlink, and also owns Musk's controversial artificial intelligence (AI) firm xAI. The initial public offering (IPO) on the US stock market is set to be the largest in Wall Street history and could start next month under the ticker symbol SPCX. Because of the shares he will own in SpaceX, the IPO could make billionaire Musk, who is already the world's richest person, a trillionaire. SpaceX values itself at $1.25tn, and Musk's majority ownership of the company means his share could be worth more than $600bn.

The ex-employees, who cofounded a new AI watchdog group, say investors deserve more information about xAI's safety practices before SpaceX goes public. Two former OpenAI employees and a group of AI safety nonprofits are warning that Elon Musk's AI lab, xAI, could become a liability for prospective investors in SpaceX, which is preparing to file what's expected to be the largest initial public offering in Wall Street History. In a letter directed to investors published on Tuesday, the ex-staffers highlighted what they describe as "unpriced risks" related to xAI that could complicate SpaceX's reported plans to raise up to $75 billion as part of its IPO. The rocket company's private valuation shot up to over $1 trillion after it acquired xAI last year . Musk claimed his rocket company could launch data centers into space for his AI lab, but the letter's authors argue that xAI's poor record on safety issues could complicate how investors view the combined company as it gets ready to submit its IPO prospectus filing .

It's called Grok Build, and it's still in its early beta version that's initially only available to SuperGrok Heavy subscribers paying $300 per month for the service. It says it will take user feedback from the early beta release to improve the product. SuperGrok Heavy users can install the beta from xAI's website and then log into their account to be able to access it. As Bloomberg notes, xAI has been trying to catch up to its rival companies like Anthropic and OpenAI. Elon Musk, the company's founder and CEO, previously admitted that it has fallen behind its competitors when it comes to coding.

Musk's xAI races to get Wall Street firms to use Grok chatbot A chat window for chatbot Grok. Musk's artificial intelligence venture, xAI, is moving with urgency to boost revenue by selling chatbot subscriptions and access to its computing resources before SpaceX's expected IPO next month. Billionaire Elon Musk's xAI has recruited multiple Wall Street firms with ties to his business empire to test its Grok chatbot, according to people familiar with the matter, part of a push to bolster revenue ahead of parent company SpaceX's initial public offering. Apollo Global Management and Morgan Stanley have begun using Grok internally alongside software from other AI model makers, said the people, who spoke on condition of anonymity as the information is not public. Valor Equity Partners is also using Grok, the people said. Despite some banks signing up for Grok, financiers are rarely using the chatbot for work, some of the people said.

Plus: After years of insults, Anthropic and SpaceX have teamed up. IVF has brought millions of babies into the world over the last four decades. But the process can still be slow, painful, and expensive--and far from guaranteed to work. Now, a wave of new technologies aims to change that. Researchers are using AI to identify promising sperm and embryos, developing robotic systems that could automate parts of the IVF process, and even exploring controversial genetic editing techniques designed to prevent inherited disease. The technologies could make IVF more effective and accessible.

SpaceX backs Anthropic with data centre deal amidst Musk's OpenAI lawsuit Anthropic has reached a deal to tap the computing resources of Elon Musk's SpaceX, marking a detente with its one-time critic and a boost for both companies in the high-stakes artificial intelligence race. Under the agreement announced on Wednesday, Anthropic will use the full computing power of SpaceX's Colossus 1 facility in Memphis, Tennessee, which houses more than 220,000 Nvidia processors and will give the Claude chatbot maker 300 megawatts of new capacity within a month. That's enough electricity to power more than 300,000 homes - as the Dario Amodei-led company seeks to boost the capacity of its Claude Pro and Claude Max AI assistants for subscribers. The tool allows AI systems to review work between sessions, spot patterns, and update files that store user preferences and other context. Available as a research preview, "dreaming" comes with software for managing agents, or AI programmes that perform tasks with little human involvement.

Anthropic has partnered with SpaceX to double Claude Code usage limits across Pro, Max, Team, and Enterprise plans, according to PCWorld. The deal provides access to SpaceX's Colossus 1 data center featuring over 220,000 Nvidia GPUs, significantly boosting Anthropic's computing capacity. This partnership marks a surprising shift, as Elon Musk previously criticized Anthropic but recently expressed being impressed after meetings with company staff. Instead of downgrading its most affordable Claude subscription plan by dropping access to Claude Code, Anthropic has instead doubled Claude Code usage rates for subscribers, starting today. All it took was an eyebrow-raising alliance with an unlikely partner.

In an unexpected turn, the two companies signed a deal for Anthropic to use computing resources from Elon Musk's xAI. Anthropic and Elon Musk's SpaceX said on Wednesday that the two entities have signed an agreement for Anthropic to use computing resources from xAI's data center in Memphis, Tennessee. It's the latest tie up in an industry that is scrambling to find enough computers to run complex AI software. SpaceX and xAI were previously separate companies, but the two merged earlier this year. The combined entity, also owned by Musk, is called SpaceXAI.
