Reports are saying SpaceX might IPO soon to raise $50 billion at a $1.5 trillion valuation. Musk apparently merged the rocket business with xAI for this move. The capital would likely go toward funding space-based AI data centers. Earth-based data centers are struggling with rising electricity and cooling costs. Putting servers in orbit could tap into constant solar power and extreme cold, potentially cutting cooling costs by 90%. It is still a huge physics challenge to cool things in a vacuum, but SpaceX's low launch costs with Starship give them a major advantage here. The article also noted nuclear companies like Oklo and NuScale Power as Earth-bound alternatives, since they are building small reactors for remote data centers.
