SpaceX IPO Left $16.7 Billion on the Table, Tripling Prior U.S. Share Offering Record
3 articles · Updated · Fortune · Jun 19
Summary
$16.7 billion in foregone proceeds makes SpaceX’s June 12 IPO the biggest underpricing ever for a U.S. ordinary-share offering, including the 15% greenshoe, after shares closed 19% above the $135 offer price.
That missed cash matters because SpaceX raised $86 billion but had already committed $62.6 billion, leaving about $23 billion from the deal for a capital-hungry AI buildout.
SpaceX’s finances remain stretched: it spent $31 billion on capex over the past five quarters, four times operating cash flow, while Q1 AI-related infrastructure spending alone reached $7.7 billion.
By June 18, the stock had climbed to $185, valuing SpaceX at about $2.44 trillion and increasing pressure on investors to justify growth that some estimates put near $1 trillion in annual revenue within a decade.
The funding gap could mean more equity issuance and dilution—already highlighted by SpaceX’s planned $60 billion all-stock purchase of Cursor, which would dilute shareholders by about 2.4% at current valuations.
