SpaceX has completed a record $75 billion initial public offering, incorporating a standard 'greenshoe' option that could allow the company to raise an additional $11.2 billion. This provision, formally known as an over-allotment option, is designed to help manage stock price volatility in the crucial first few weeks after a company lists.
The greenshoe option enables underwriters, in this case Morgan Stanley, to sell up to 15% more shares than initially offered at the IPO price of $135 per share. If demand for SpaceX's stock remains strong, underwriters can exercise this option to purchase additional shares from the company to cover their short positions, thereby increasing the total capital raised.
Named after the 1960 IPO of Green Shoe Manufacturing, this mechanism serves a dual purpose: it provides underwriters with a tool to support orderly trading and offers issuers an opportunity to secure more capital if investor demand exceeds expectations. Historically, companies like Alibaba have fully exercised their greenshoe options to capitalize on strong demand, while others, like Uber, have seen underwriters use the option to moderate selling pressure when stock prices fell below the IPO price.
