Elon Musk’s xAI raises $6 billion in fresh funding: ‘We are gonna need a bigger compute!’

• Elon Musk’s xAI raised $6 billion in its Series C fundraising, the startup announced on Monday.
• The round’s participants included Sequoia Capital, and Nvidia and AMD were strategic investors.
• The AI startup plans to use the cash to ship new products and build out its infrastructure.

Elon Musk’s xAI has completed its Series C funding round, raising a total of $6 billion, it revealed in a Monday blog post.

Musk’s artificial intelligence company said the participants included a16z, Sequoia Capital, Morgan Stanley, BlackRock, Fidelity, Saudi Arabia’s Kingdom Holdings, Oman and Qatar’s sovereign wealth funds, California-based Lightspeed Venture Partners, Chicago-based Valor Equity Partners, Dubai-based Vy Capital, and UAE-based tech investor MGX.

xAI added that chipmakers Nvidia and AMD took part as strategic investors and “continue to support xAI in rapidly scaling our infrastructure.”

Musk shared the news on his X platform, writing, “A lot of compute is needed.” He also tagged xAI in a meme generated by xAI’s Grok chatbot that riffed on a famous line from the movie “Jaws.”

Musk was likely underscoring the vast amount of processing power needed to train and run AI models, which has fueled enormous demand for microchips and underpinned a roughly eightfold rise in Nvidia stock since the start of 2023.

xAI, founded in March last year, raised $6 billion at a post-money valuation of $24 billion in its Series B round in May. The Wall Street Journal reported in late November that it had raised a further $5 billion at a $50 billion valuation. It appears xAI ultimately raised a bigger round of $6 billion, but the valuation wasn’t disclosed.

The startup highlighted its progress since May in its blog post, including its launch of Colossus — the world’s largest AI supercomputer powered by 100,000 Nvidia Hopper GPUs, which xAI plans to double in size to 200,000 chips soon.

xAI also released version two of Grok, an application programming interface (API) for developers to build on its platform, its Aurora image generation model for Grok, and Grok on X.

The company said it’s training Grok 3 and “focused on launching innovative new consumer and enterprise products that will leverage the power of Grok, Colossus, and X to transform the way we live, work, and play.”

Musk’s fledgling business said it would use the Series C funds to accelerate its infrastructure growth, ship new products, and speed up its research and development of tech that will enable its “mission to understand the true nature of the universe.”
