Who owns SpaceX — and who controls it.

SPCX uses a dual-class capital structure that is now standard across founder-led tech companies. Class A is what the public buys and what trades. Class B carries supervoting rights and is held by insiders. The structure mirrors Meta, Alphabet, and Palantir — and is more shareholder-friendly than Snap's 2017 IPO, which issued non-voting Class A shares only.

The S-1's principal stockholders table names every direct holder of more than 5% of outstanding shares, plus all directors and executive officers. The disclosed positions:

SpaceX has run a series of structured tender offers — recurring opportunities for employees and earlier investors to sell shares back to the company or to incoming late-stage funds at company-set prices. The S-1 discloses three sets of relevant valuation marks:

The cadence from $350B in mid-2025 to a $1.75T target a year later is the question every IPO analyst is being asked. The S-1 attributes the step-up to four factors: (1) the absorption of xAI at the disclosed $250B mark, (2) Starlink's revenue growth from $7.7B to $11.4B over those twelve months, (3) realized progress on Starship orbital flight tests, and (4) a broader re-rating of "platform" AI businesses. Skeptics point to the same multiple expansion as a hot-IPO premium — see our valuation analysis for both sides.

At a $1.75 trillion enterprise valuation and a $75 billion gross raise, the offering represents approximately 4.3% of the post-money equity. The post-IPO ownership stack — Class A and Class B combined, on an as-converted economic basis — breaks down approximately as follows:

Pro forma estimate. Final percentages depend on the share count and price set in the first S-1/A and on any greenshoe exercise.

The S-1 names the standard 180-day lock-up on officers, directors, and pre-IPO stockholders. Counting forward from a June 11 pricing date, the lock-up expires on or around December 9, 2026. After that date, the only sales restriction on insiders is Rule 144 — which limits affiliate sales to 1% of outstanding per quarter — and any continuing contractual restraints.

The volume that becomes eligible to sell at lock-up expiry is roughly:

• Employee + former employee holdings across two decades of options grants and tender-eligible RSUs.
• Late-stage growth investors who bought into the 2023, 2024, and 2025 tender rounds at $180B, $210B, and $350B valuations.
• Strategic and corporate holders including Alphabet, the Founders Fund, and Valor Equity Partners.
• Sovereign and family office holders who participated in pre-IPO tenders.

None of these holders are required to sell, and many institutional growth funds have well-documented multi-year holding mandates. But the overhang is mathematically large: the public float at IPO is ~4.3% while the eligible-after-lock-up supply is several multiples of that. The historical pattern in dual-class IPOs is for the stock to weaken into the lock-up date and to recover as initial sales clear.

Investor objections to dual-class structures are common but rarely binding — index inclusion forces most large institutional accounts to hold these names anyway. The relevant peer set:
