In the late hours of the night on October 8, 2025, Jensen Huang, the CEO of NVIDIA, revealed that NVIDIA has made an investment in Elon Musk's AI - focused startup, xAI. The investment sum has soared to a staggering US$2 billion. This financial injection comes in the form of a blend of debt and equity, and is earmarked to power xAI's Colossus 2 supercomputer GPU. Huang was visibly enthusiastic about the progress of xAI's fundraising endeavors and expressed his keen interest in expanding NVIDIA's involvement in a wider array of Musk - related ventures. (Here, "confirmed" is changed to "revealed" to make the expression more natural in the context of news - breaking. "Invested in" is replaced with "made an investment in" for a bit more formality. "Funding supports" is adjusted to "This financial injection...is earmarked to power" to better convey the purpose of the investment in a more English - idiomatic way. "Expressed excitement" is rephrased as "was visibly enthusiastic" to add more vividness. "Hopes to participate in more fields involving Musk" is transformed into "expressed his keen interest in expanding NVIDIA's involvement in a wider array of Musk - related ventures" to make the sentence more detailed and fluent.)
