- SpaceX filed its long-awaited S-1 on Wednesday seeking a ~$2 trillion valuation—the largest IPO on record—planning to use proceeds to build space-based AI data centers in pursuit of a stated $28.5 trillion addressable market.
- Elon Musk controls 85% of SpaceX's voting power pre-IPO despite holding 41% of shares, and can earn 1 billion additional shares if market cap hits $7.5 trillion and a permanent Mars colony is established.
- xAI, merged into SpaceX in February, drove $6.4 billion of the company's 2025 operating loss (up from $1.6 billion in 2024) and pushed Q1 2026 to a $1.9 billion operating loss on $4.7 billion in revenue.
- Anthropic committed to pay SpaceX $1.25 billion per month through May 2029—roughly $45 billion total—for AI computing capacity likely covering about 1 gigawatt, implying an annual cost of $13–15 billion per gigawatt.
- Starlink generated $4.4 billion in 2025 operating profit (up more than 100% year over year) with over 10 million customers and roughly 10,000 operational satellites, remaining SpaceX's lone highly profitable unit.
- SpaceX will trade under the symbol SPCX on both Nasdaq and the newly created Nasdaq Texas, a Texas-domiciled venue that offers corporate-governance rule relief for issuers.
- Adjacent stocks swung on the filing: Rocket Lab fell 6.6%, while satellite-broadband peer AST SpaceMobile jumped 7.4% and AI-compute provider CoreWeave gained 6.2%.
Why it matters: SpaceX's $2 trillion IPO tests whether public investors will underwrite a company whose economics are dominated by a money-losing xAI subsidiary and whose super-voting structure gives Musk near-absolute control. The Anthropic commitment—$1.25 billion a month through 2029—provides one of the first hard data points on AI-compute pricing, anchoring the orbital data center thesis at an implied $13–15 billion per gigawatt per year.
