SpaceX shares closed their first week of public trading up 37% from the $112 IPO price, reaching $153.44 on Friday afternoon across five retail platforms. The $44 billion raise—largest since Saudi Aramco in 2019—saw $2.1 billion in retail order flow through Charles Schwab, Fidelity, Robinhood, SoFi, and Morgan Stanley's E-Trade by Thursday's settlement.
The company priced 393 million shares Wednesday evening, valuing SpaceX at $180 billion post-money. Lead underwriters Goldman Sachs and Morgan Stanley allocated 22% of the offering to retail accounts, double the 11% average for technology IPOs above $10 billion since 2010. Fidelity processed $780 million in SpaceX orders within the first 36 hours, surpassing its previous single-stock record set during Rivian's 2021 debut. Robinhood reported 1.2 million accounts placed orders, though average order size of $1,840 suggests concentrated interest among smaller allocators rather than broad retail participation.
The 37% first-week gain outpaced the 30% average for the thirty largest US technology IPOs since 2011, per Truist Advisory. That cohort includes Meta (18% week-one gain), Alibaba (38%), and Snowflake (111%). SpaceX's performance sits closer to Airbnb's 113% December 2020 debut than to the 9% median for venture-backed aerospace and defense listings over the same period. Selling pressure emerged Thursday as early Founders Fund and Sequoia positions began clearing lockup through a pre-arranged secondary window, moving 14 million shares at an average $151 print.
What matters for allocators is the durability of the retail bid and whether institutional crossover funds treat this as a momentum trade or a multi-year position. SpaceX generated $11.8 billion in trailing twelve-month revenue as of March, up 54% year-over-year, with Starlink subscriptions contributing $6.2 billion and launch contracts $4.1 billion. The company disclosed $1.9 billion in EBITDA for the same period, implying a 95x post-IPO enterprise value to EBITDA multiple—rich against Boeing's 12x and Lockheed Martin's 14x, though those comps lack exposure to broadband scaling or reusable launch economics. The 22% retail allocation reflects underwriter concern that institutional appetite alone wouldn't absorb the size of the deal without leaving 15-20% first-day pop money on the table.
Operators should watch the 180-day lockup expiration in December, when 1.1 billion shares held by Musk, early employees, and venture funds become eligible for sale. The company's S-1 filing shows Musk holds 42% of outstanding equity post-IPO and has pledged not to sell for 24 months, but no similar commitments bind Founders Fund's 8.1% stake or Sequoia's 6.4%. Starlink's path to 10 million subscribers by year-end—currently at 7.3 million—will determine whether the $180 billion valuation holds or compresses toward the $125 billion private secondary market price from February. Truist noted that 19 of the 30 IPOs in their sample gave back more than half of week-one gains within 90 days, a reminder that momentum and fundamentals separate at different speeds.
The $2.1 billion in retail flow inside one week marks the largest single-stock onboarding event since the Coinbase direct listing moved $1.8 billion in April 2021, and it arrived without the compliance delays that kept Rivian and Stripe retail-dark for their first 72 hours of trading.
