SpaceX Filed Its S-1. Musk Gets 85% Voting Control and a 1 Billion-Share Mars Bonus.

SpaceX submitted its S-1 to the SEC on May 20, setting up what would be the largest IPO in history when it prices. The company will list under the ticker "SPCX." Reported 2025 revenue: $18.7 billion, up 33% year over year. Starlink generated approximately $1.2 billion in quarterly profit and is the operating driver; the launch and AI-related divisions posted losses. Elon Musk will retain 85% voting control through Class B shares. His proposed compensation package includes 1 billion performance-based shares tied to achieving a permanent human colony on Mars with one million inhabitants.

The cap-table read is unusual at every layer. The 85% voting control via dual-class shares is structurally common (Meta, Alphabet, NYT all have similar structures), but the magnitude is at the high end of what public markets have absorbed historically. Most dual-class founders retain 30-60% voting control; 85% effectively makes SpaceX a permanent founder-controlled company in public form. Index inclusion may be constrained. S&P and major index providers have varying policies on dual-class shares, and some indexes exclude companies with founder voting control above stated thresholds. That affects passive inflows post-IPO and is a real number for institutional position sizing. The performance-based comp package is the genuinely novel piece. 1 billion shares vested against the construction of a Mars colony with one million inhabitants is an asymptotic vesting target. Even on optimistic SpaceX trajectories, the Mars population milestone is decades away. The package is functionally an equity grant with deferred mathematical vesting, which means Musk realizes economic ownership of the underlying shares only on extreme outcomes. Whether that survives shareholder approval votes is uncertain. ISS and Glass Lewis are unlikely to recommend in favor of a package this structured.
