SpaceX Closes First Day at $161, Crowning Itself the Largest IPO in History

SpaceX made its long-awaited public market debut on June 12, 2026, and Wall Street responded with thunderous enthusiasm. Shares of the rocket and satellite company — trading under the Nasdaq ticker SPCX — opened at $150, an 11% premium to the $135 IPO price, and ground higher throughout the session before closing at $160.95, up 19.2% for the day. By the time after-hours trading subsided Friday evening, SPCX was changing hands at $166.76, adding another 3.5% and pushing the company’s market capitalization close to $2.2 trillion.

The offering shattered every record in the annals of equity capital markets. By selling 555.56 million common shares at $135, SpaceX raised approximately $75 billion in a single day — nearly three times the previous benchmark set by Saudi Aramco’s $29.4 billion offering in December 2019. Underwriters also hold a “green shoe” option on roughly 83 million additional shares worth around $11.2 billion, meaning the total raise could approach $86 billion if exercised in full.

The Numbers Behind the Valuation

At its IPO price of $135, SpaceX was valued at approximately $1.75 trillion — already a staggering figure for a company that was private just days earlier. By the closing bell on June 12, that market cap had swelled to roughly $2 trillion, vaulting SpaceX into the sixth spot among U.S. companies by market value. As one analyst put it, Elon Musk’s SPCX is already more than twice the size of Berkshire Hathaway.

The S-1 filing, which landed publicly in May, revealed that SpaceX generated approximately $25 billion in revenue in FY2025 with $8 billion in EBITDA — profitability metrics that surprised many observers who had assumed the company was still burning cash at scale on Starship development. The two core businesses driving those results are the Falcon 9 launch franchise and Starlink, the low-Earth-orbit satellite internet constellation that now operates more than 7,000 satellites and serves over 5 million subscribers worldwide.

The launch business remains the bedrock. SpaceX completed 144 orbital missions in 2025, representing more than 60% of all orbital launch attempts globally in that year — an extraordinary market dominance that competitors have been unable to erode despite years of effort. Starship, the fully reusable super-heavy-lift launch vehicle, achieved seven consecutive successful flight-and-catch operations in its most recent test campaign, with first commercial payloads expected in late 2026.

Retail Investors Storm the Gates

One of the most striking features of the SPCX offering was its deliberately oversized retail allocation. SpaceX targeted roughly 30% of IPO shares for individual investors — three to six times the typical 5-10% allocation in major listings. The rationale was both symbolic and strategic: Musk has spent years cultivating a retail fanbase among space enthusiasts and Tesla devotees, and SpaceX wanted those communities to have a genuine stake in the company’s future.

The gambit worked. Preliminary data indicated that SPCX became the most-bought stock by retail investors on June 12, with retail trading turnover reaching $453 million within the first session alone. Pre-IPO demand from individual investors reportedly exceeded $100 billion in indications of interest — a figure that would have been unthinkable even for the most hyped technology offerings of the last decade.

Overall, the IPO book was oversubscribed approximately four times, with institutional demand drawn from sovereign wealth funds, pension plans, and mutual funds that have long wanted listed exposure to the private-launch economy. Hedge funds also participated aggressively, eager to gain a position in a company whose two revenue streams — launch and broadband — operate in markets with structural long-term growth.

Strategic Significance of Going Public

The listing provides SpaceX with a hard currency for acquisitions, employee compensation, and balance sheet flexibility that private status denied it. Despite multiple tender offers and secondary transactions over the years, stock-based compensation had been difficult to price and even harder to convert into liquidity for the tens of thousands of current and former employees holding options. That problem is now solved.

The IPO also imposes new disclosure requirements and governance pressures. SpaceX named “key-man risk” as a material risk factor in its S-1, acknowledging explicitly that the company’s direction is inseparable from Elon Musk’s continued involvement. Musk remains CEO of Tesla, xAI, The Boring Company, and Neuralink simultaneously — a span of responsibilities that institutional investors have repeatedly flagged as a governance concern. Whether SpaceX’s board will push for more conventional executive accountability structures remains to be seen.

The listing comes at a notable moment in the technology IPO cycle. Following the Anthropic, OpenAI, and ARM listings over the past eighteen months, SPCX completes a remarkable transfer of private-market value into public equities. Goldman Sachs analysts called it “the final proof point that the AI-and-space infrastructure supercycle is fully investable from public markets.”

What Comes Next

Near-term catalysts include the first Starship commercial mission, Starlink’s ongoing expansion into aviation and maritime markets, and the potential launch of a next-generation satellite constellation for direct-to-device cellular service in partnership with T-Mobile. Longer term, the most transformative scenario involves using Starship as a Mars transport vehicle — a mission that would require hundreds of missions per year and an entirely different cost structure than any launch provider has ever achieved.

For Musk, Friday’s close represents a personal milestone that transcends any single number on a ticker screen. SpaceX was founded in 2002 on a thesis that private companies could build reusable rockets economically and eventually make humanity multiplanetary. Twenty-four years later, the public market has delivered its verdict: that thesis is worth roughly $2 trillion.

Whether that valuation is justified will ultimately depend on execution against an extraordinarily ambitious roadmap. Investors who bought SPCX on June 12 are wagering that the answer is yes — and they bought in at a premium that leaves very little room for doubt.
