SpaceX priced its IPO at $135 per share on June 11, 2026, raising $75 billion and valuing the company at $1.77 trillion — the largest public offering on record, per Reuters. Class A common stock began trading on the Nasdaq Stock Market LLC and Nasdaq Texas, Inc. on June 12, 2026, per the company's Australian lodgement prospectus.

The debut printed hard. Shares peaked intraday at $176.52 before closing at $160.95 — a 19.2% gain on the offer price — per Yahoo Finance. That first-day close lifted the implied market cap well above the IPO valuation, compressing the discount that retail and institutional allocants locked in at $135.

Demand, Structure, and the Retail Allocation

The order book approached four times oversubscribed ahead of pricing, Reuters reported. That level of excess demand, while not unusual for marquee listings, gave underwriters significant latitude in final price discovery — and the $135 print came in at the top of expectations. SpaceX set aside 30% of IPO shares for retail investors, an unusually large retail tranche by U.S. norms, where allocations to non-institutional buyers typically run 10–20%. The decision reflects both the company's consumer-facing profile via Starlink and a deliberate broadening of the shareholder base.

Elon Musk retained 82% control of the company after the offering, per Reuters. At the first-day close, the Reuters-reported milestone followed: Musk became the world's first trillionaire, driven by the combination of his retained SpaceX stake and other holdings. The 82% retention figure matters structurally — it means the float is thin relative to the total valuation, which concentrates price discovery in a relatively small pool of tradable shares and amplifies both upside volatility and potential liquidity gaps.

Growth Narrative and Prospectus Positioning

SpaceX's IPO materials flagged Starlink, AI, and space-based data centers as the primary growth vectors, per Reuters. That framing is notable: the company is not pitching itself purely as a launch provider. It is positioning Starlink's recurring broadband revenue as a subscription infrastructure business, with AI integration and orbital data center capacity as long-duration optionality. The EU prospectus, approved by BaFin and published June 6, 2026, confirms the multi-jurisdictional nature of the offering — SpaceX ran a coordinated global book across U.S., European, and Australian markets simultaneously, per the BaFin-approved document.

The $1.77 trillion entry valuation puts SpaceX in rarefied company on the public markets. At that figure, the IPO price implied a revenue multiple — and by extension a growth expectation — that prices in substantial execution on the Starlink and nascent AI infrastructure thesis. First-day buyers at $160.95 paid an even steeper premium. Whether the underlying cash generation can grow into that multiple is precisely the question the prospectus does not answer, and that analysts will now be stress-testing.

The thin float cuts both ways. In the near term it supports price stability, since there is limited stock available to short. Over time, lock-up expirations and any secondary sales by Musk or early institutional holders will be closely watched events. At 82% retention, even modest sales from the controlling shareholder would represent meaningful supply relative to the float — a dynamic that will likely keep the options market busy.

For practitioners, the structural takeaways are straightforward: a record IPO raise, a 4x oversubscribed book, a large retail allocation, and a first-day close 19% above issue price are unambiguously strong execution metrics. The more durable question is whether the $1.77 trillion valuation — now marked higher by the market itself — reflects a business that can compound into the implied expectations. That is a forward earnings question, and the prospectus, however detailed, is not the place to find the answer.
