SpaceX IPO raises $85.7 billion after greenshoe

SpaceX completed its initial public offering on June 12, 2026, raising $75 billion at $135 per share, according to CNBC. On June 15, CNBC and Reuters reported that underwriters Goldman Sachs and Morgan Stanley exercised the standard overallotment option -- commonly called a greenshoe -- purchasing an additional 83.3 million shares from SpaceX and bringing total IPO proceeds to $85.7 billion, per CNBC.

A greenshoe option allows underwriters to sell more shares than the issuer originally planned. When demand is high, underwriters sell the overallotment shares into the market. If the stock price holds at or above the offering price after listing, underwriters exercise the option, buying those shares directly from the issuer at the offering price, directing additional proceeds to the company. Goldman Sachs and Morgan Stanley held this overallotment option on 83.3 million additional SpaceX shares, per CNBC.

At $85.7 billion in total proceeds, the SpaceX IPO ranks among the largest public offerings ever recorded, per market coverage. SpaceX's primary businesses include rocket manufacturing and launch services, the Starlink global satellite broadband network, and development of the Starship launch system. Starlink's global operation relies on machine learning for satellite routing, capacity optimization, and handoff management across its constellation. SpaceX also applies computer vision and reinforcement learning to rocket landing systems and manufacturing quality control.

Analysts and practitioners will track how SpaceX deploys the capital -- specifically any investments affecting Starlink's AI-driven network management, autonomous landing system development, or AI infrastructure for manufacturing. The IPO also signals broad investor appetite for large-scale technology platforms with embedded AI components, relevant context for how capital markets currently price AI-adjacent infrastructure.
