Recent reports clarify SpaceX's valuation at $800 billion, not $80 billion, from its latest secondary share sale at $421 per share (Yahoo Finance, Dec 13, 2025). This doubles the prior $400 billion mark and exceeds OpenAI's $500 billion record, positioning SpaceX as the top private company.

The 2026 IPO plans aim to fund Starship flights, space AI data centers, and a lunar base, per internal memos. Projections align with this $800B figure, driven by Starlink growth and reusability tech. No sources support the $80B claim—likely a mix-up.
