SpaceX raised over $100 billion（約16兆円） in capital after its IPO and bond offering, with plans to deploy it primarily toward artificial intelligence initiatives representing over 90% of its $28.5 trillion（約4600兆円） addressable market opportunity. The company already operates AI data centers—Colossus 1 runs over 220,000 Nvidia GPUs, and Colossus 2 generates $150 million（約240億円） monthly in revenue from a major tenant. This spending spree directly benefits SpaceX's suppliers: Nvidia, which dominates AI data center chips with an 85% market share, and Tesla, which has sold over $1 billion（約1600億円） in Megapacks to power the infrastructure since 2024.

SpaceX raised over $100 billion（約16兆円） through an IPO and bond offering and plans to deploy this capital quickly, with more than 90% of its $28.5 trillion（約4600兆円） total addressable market opportunity centered on artificial intelligence. The company already operates Colossus 1, a supercomputer incorporating over 220,000 Nvidia GPUs, and Colossus 2 recently signed a deal where another AI company will pay $150 million（約240億円） per month for access to the data center's Nvidia chips.
Why it matters
SpaceX's post-IPO spending on AI infrastructure will directly increase revenues for its suppliers—particularly Nvidia, which holds an estimated 85% market share in AI data centers. SpaceX has also purchased over $1 billion（約1600億円） in Tesla Megapacks (large battery storage units) since 2024 to power its data center build-out, and Tesla invested $2 billion（約3200億円） into xAI, which later fully merged with SpaceX, creating financial and operational ties between the two companies.
What to watch
SpaceX needs to build more data centers to support AI growth, and those data centers will continue to rely on Nvidia products. Tesla is also developing autonomous driving and robotaxi services, and direct access to SpaceX's AI capacity offers potential to advance Tesla's own AI and autonomy capabilities.
SpaceX's capital raise fundamentally redefines how investors should think about the company: while the public perceives it as a space business, its IPO prospectus reveals that more than 90% of its $28.5 trillion（約4600兆円） addressable market opportunity centers on artificial intelligence. The company claims in its prospectus to have identified "the largest actionable total addressable market in human history," and it needs this fresh capital because it is currently losing money at a record pace. Growth in AI is positioned as the path to profitability.
The practical effect of SpaceX's spending is to funnel capital to its suppliers. Nvidia, which already supplies SpaceX and xAI with GPUs—Colossus 1 alone incorporates over 220,000 Nvidia chips—stands to see direct revenue increases as SpaceX builds more data centers. Tesla, despite being a separate company, is deeply intertwined with SpaceX through shared ownership under Elon Musk: SpaceX has purchased over $1 billion（約1600億円） in Tesla Megapacks since 2024 to power these data centers, and Tesla invested $2 billion（約3200億円） into xAI before it merged with SpaceX. For Tesla, the connection offers more than near-term battery sales; direct access to SpaceX's expanding AI capacity could materially advance Tesla's own autonomous driving and robotaxi ambitions, which are now central to the company's valuation.
