SpaceX has surged past Amazon to become the world’s fifth most valuable company, just four days after its initial public offering (IPO) on the Nasdaq. The company’s shares have climbed approximately 50% since trading began last Friday, driving its market capitalization to around $2.7 trillion, briefly surpassing both Amazon and Microsoft during intraday sessions.
The IPO marked a significant milestone for Elon Musk, making him the world’s first trillionaire, with a personal net worth estimated at $1.3 trillion. SpaceX’s valuation now places it among the six most valuable companies globally, narrowly trailing tech giants such as Microsoft, Apple, Nvidia, Alphabet, and Amazon. However, despite the lofty valuation, SpaceX’s latest reported financial results show a sizable net loss of nearly $5 billion on revenues of about $19 billion in 2025—figures that stand in stark contrast to Amazon’s $717 billion revenue and $78 billion net income for the same period.
SpaceX’s business empire extends beyond its renowned aerospace ventures, encompassing Elon Musk’s AI lab xAI, the social media platform X, satellite internet provider Starlink, and its core rocket manufacturing operations. Starlink remains the company’s only profitable segment. The high valuation has been met with a mix of enthusiasm and caution among analysts and investors. Some point to SpaceX’s broad strategic vision, including ambitions to establish a human colony on Mars and build a lunar economy, as well as its expanding AI initiatives that could justify the premium valuation. Others warn that the stock’s rapid ascent may be driven more by bullish market sentiment than underlying profitability, with predictions by some experts forecasting potential declines of over 50% within a year.
On Tuesday, SpaceX announced a $60 billion acquisition of Anysphere, the San Francisco-based developer of the AI-assisted coding application Cursor, in an all-stock deal expected to close in the third quarter of 2026. This move aims to strengthen SpaceX’s AI capabilities, particularly in software engineering, a sector where generative AI has shown lucrative potential. Cursor, which serves over one million developers, has been constrained by limited computing resources, a gap SpaceX’s infrastructure could help fill. The acquisition aligns with SpaceX’s strategic intent to enhance its AI model, Grok, which currently trails behind competitors like OpenAI and Anthropic in coding proficiency.
Industry analysts have offered differing views on the acquisition’s impact. Some see ownership of Cursor as a valuable shortcut to enterprise AI revenue, gaining access to a ready developer base and enhancing model training through usage data. However, others caution that while the deal is a positive step, it may not close the competitive gap with dominant AI firms.
The IPO and subsequent trading have also seen heightened market activity in SpaceX options, reflecting both the enthusiasm and volatility surrounding the stock. Trading volumes of derivatives linked to SpaceX shares have been significant, with bullish call options generally outpacing bearish bets.
As SpaceX integrates into major stock indices such as Nasdaq, FTSE, and MSCI, passive investing inflows are expected to bolster its shares further. The company’s debut and performance are being closely watched as potential benchmarks for upcoming public listings from other AI leaders, including Anthropic and OpenAI, which are preparing for significant market entries later this year.
