SpaceX IPO Hits Historic $85.7 Billion as Greenshoe Option is Exercised

Elon Musk’s SpaceX has rewritten the history books by expanding its massive initial public offering (IPO) proceeds to a staggering $85.7 billion. This surge follows the decision by underwriters to exercise the "greenshoe" option, responding to unprecedented investor demand that continues to push the company's valuation into uncharted territory.

Record-Breaking Proceeds and the Greenshoe Effect

Initially, SpaceX raised $75 billion by selling 555.56 million shares at a price of $135 per share. However, due to the overwhelming appetite from both institutional and retail investors, the underwriters—led by Goldman Sachs and Morgan Stanley—exercised the greenshoe option to purchase an additional 83.3 million shares. This maneuver increased the total haul by $10.7 billion, bringing the final figure to $85.7 billion.

In the U.S. stock market, the greenshoe option serves as a strategic "safety valve." It allows underwriters to stabilize a stock's price and manage volatility when demand far outstrips supply. Because SpaceX shares surged 19% immediately following its Nasdaq debut on Friday, the decision to exercise this option was a natural response to satisfy the massive orders waiting in the wings.

Unprecedented Demand and Market Impact

The scale of the SpaceX IPO is virtually unmatched in financial history. Reports indicate that the offering attracted more than $250 billion in investor orders, meaning the IPO was oversubscribed by roughly three-and-a-half to four times. This level of interest underscores the market's intense fascination with Musk’s conglomerate, which spans rocketry, artificial intelligence, and satellite internet.

Analysts have described the debut as a "Goldilocks" entry—a perfect balance where investors secured strong first-day gains without the company feeling it had priced the shares too conservatively. Following the blockbuster debut, shares rose an additional 7% in early Monday trading. This momentum has propelled SpaceX’s market capitalization above the $2 trillion mark, a milestone that has also made Elon Musk the world’s first trillionaire.

A Benchmark for the Next Wave of Mega-Listings

The SpaceX IPO is more than just a single company's success; it serves as a critical litmus test for the broader tech sector. The massive capital influx suggests that investor appetite for high-growth, high-valuation technology firms remains robust.

This historic listing sets the stage for a potential new era of "mega-listings." Financial markets are now closely watching other AI heavyweights, such as Anthropic and OpenAI, which are reportedly expected to pursue public listings later this year. The success of SpaceX provides a blueprint for how these massive AI-driven entities might navigate the complexities of the public markets.
