There are plenty of good artificial intelligence (AI) stocks available to investors these days, and if you've got $1,000 to invest right now, you've likely thought about buying Micron Technology (NASDAQ: MU), Nvidia (NASDAQ: NVDA), or Space Exploration Technologies (NASDAQ: SPCX). The case for SpaceXWhile originally a rocket launch company, SpaceX's purchase of xAI and the company's massive build-out of data centers have expanded SpaceX into a full-fledged AI company. What's more, SpaceX is considered by some analysts a "sovereign AI" company, meaning it controls nearly all of its artificial intelligence software and hardware. CPUs can be especially good at processing AI agent tasks, which is why some tech companies, including Alphabet, are designing their own CPUs to be used in AI data centers. Nvidia recently revealed more details about its next-generation Vera CPU for AI, which will directly compete with Intel and AMD CPUs.
