SpaceX closed Thursday at $135.12, marking the first session below its $135 initial offering price set six trading days prior. The stock opened at $142 on debut, peaked intraday at $151.80, then surrendered 11% through the week as short interest climbed to 4.2 million shares and institutional money managers rebalanced post-lockup clarity.
The offering priced 180 million shares at $135, valuing the company at $243 billion fully diluted. Early retail demand pushed first-day volume to 890 million shares, triple the float, but sell-side analysts at Morgan Stanley and Goldman Sachs published neutral initiation coverage citing 58x forward revenue multiples and Starship development timelines extending into 2027. By Wednesday, daily volume had collapsed to 210 million shares, and the stock gapped down 3.8% on no company-specific news.
Three factors converge. First, Musk holds 42% of shares and has not sold; employee lockup expires in 90 days, introducing 22 million shares of potential supply. Second, SpaceX disclosed in the S-1 that Starlink achieved $4.2 billion in trailing revenue but remains EBITDA-negative, burning $1.8 billion annually on satellite deployment and ground infrastructure. Third, short sellers see technical exhaustion: the stock now trades 2.1x the volatility of the S&P 500, and options markets price 68% implied volatility through June, suggesting traders expect a $20-25 range.
Allocators now face a valuation question that didn't exist in private markets. SpaceX traded at $112 per share in secondary transactions as recently as December, a 20% discount to the IPO price. The company's dual mandate—profitable launch services generating $3.1 billion in 2024 revenue, and speculative Starlink subscriber growth targeting 10 million terminals by 2026—creates bifurcated investor bases. Growth funds model $18 billion Starlink revenue by 2028; value funds see a cyclical aerospace contractor trading at nosebleed multiples during a federal procurement slowdown.
Watch for two catalysts. SpaceX will report first-quarter earnings in mid-May, the first public disclosure of Starlink subscriber economics and Starship development capital allocation. If the lockup triggers selling pressure in July, the stock could test $115-120 support levels established in late-stage private rounds. Conversely, a successful Starship orbital refueling demonstration—currently scheduled for Q3—would validate the $8 billion NASA Artemis contract and likely reset the narrative.
The $135 breach matters less than the 90-day lockup clock and the May earnings call. Institutional holders now own 34% of the float, up from 19% at pricing, suggesting asset managers used the dip to establish positions below the IPO. The short interest, while notable, represents just 2% of shares outstanding. What looks like a failed debut is standard post-IPO price discovery. The real test comes when employees can sell and the market learns whether Starlink economics justify the valuation or whether SpaceX becomes a $100 stock trading on launch cadence and government contracts.
