What Happened to SpaceX?
SpaceX, the aerospace and AI company founded by Elon Musk, transitioned from a highly valued private entity to a publicly traded company on June 12, 2026, via the largest IPO in history. After an initial surge that briefly pushed its market capitalization above $2.6 trillion, its shares have since fallen below the IPO price of $135 amidst valuation concerns and significant short-selling activity, particularly following its merger with xAI and a recent Starship launch abort.
Quick Answer
SpaceX went public on June 12, 2026, in the largest IPO ever, pricing shares at $135 and achieving an initial valuation of $1.75 trillion. The stock, trading as SPCX on Nasdaq, initially soared to over $225, briefly making SpaceX one of the world's most valuable companies. However, by mid-July 2026, shares plummeted below the IPO price, driven by investor skepticism over its high valuation, substantial losses from its xAI merger, and a recent Starship launch abort. Short sellers have capitalized on this decline, accumulating billions in paper profits as a significant portion of the tradable float is now shorted.

🔍Deep Dive Analysis
SpaceX's journey to the public markets was a long-anticipated event, marked by a dramatic increase in private valuations over the past few years. From a $1.9 billion funding round in August 2020, which fueled its growth, the company's valuation steadily climbed through various secondary market transactions and funding rounds, reaching $74 billion in February 2021 and $127 billion by June 2022. By December 2024, a private tender offer valued SpaceX at approximately $350 billion, followed by an $800 billion valuation in a December 2025 secondary sale, signaling an imminent IPO.
The company officially made its historic public debut on June 12, 2026, listing on Nasdaq under the ticker SPCX. The Initial Public Offering (IPO) was the largest in history, raising approximately $75 billion by pricing shares at $135 each, valuing the company at an astounding $1.75 trillion. This monumental listing briefly propelled SpaceX's market capitalization to over $2.6 trillion by June 16, 2026, making its founder, Elon Musk, the world's first trillionaire. The IPO was notable for allocating a significant portion (around 30%) of shares to retail investors, a departure from typical offerings.
However, the initial euphoria was short-lived. By mid-July 2026, SpaceX shares experienced a sharp decline, falling below their $135 IPO price. On July 17, 2026, the stock dropped to $122.12, recovering slightly but remaining below its offering price, with its market value settling around $1.61 trillion to $1.73 trillion. This rapid unraveling of post-IPO gains was attributed to several factors, including profit-taking, broader tech-sector weakness, and growing skepticism regarding SpaceX's lofty valuation. A significant contributing factor was the company's financial performance, which revealed a net loss of $4.9 billion in 2025 and $4.3 billion in Q1 2026, largely due to the substantial capital expenditures and operating losses from its newly merged AI unit, xAI. The xAI merger, completed in February 2026, integrated Musk's AI venture into SpaceX, adding a new, albeit loss-making, segment to the business.
The decline in share price also attracted significant attention from short sellers. Data from Ortex Technologies and S3 Partners indicated that short sellers accumulated estimated paper profits ranging from $3.88 billion to $8.7 billion as the stock fell. The short interest in SpaceX's tradable float reached an unusually high 28-31% for a newly public company, reflecting bearish bets against its rich price-to-sales ratio (around 90-135 times 2025 revenue) and concerns over its path to profitability. Analysts expressed mixed views, with some like Raymond James maintaining bullish price targets of $800, while others, such as CFRA and Seeking Alpha, issued 'Sell' ratings, citing the disconnect between valuation and fundamentals. The upcoming expiration of lockup periods, which could release a substantial number of insider shares starting in August and significantly in September, is expected to further increase the public float and potentially add to market volatility. The company's first quarterly earnings report as a public entity, anticipated in early August, is also a critical event that investors and short sellers are closely watching.
