SpaceX’s Stock Surges Past Microsoft and Amazon After AI Coding App Acquisition
SpaceX’s stock price rose 60% above its $135 initial public offering (IPO) price on May 16, pushing the company’s market capitalization to $2.94 trillion, according to Reuters. This marked the first time the aerospace firm surpassed both Microsoft and Amazon in valuation, according to data from Bloomberg.
SpaceX’s Stock Surge and Market Cap
On May 16, SpaceX’s shares reached $225.64 during trading, a 60% increase from the $135 IPO price set on May 12. The company’s market capitalization climbed to $2.94 trillion, overtaking Microsoft’s $2.92 trillion and Amazon’s $2.67 trillion, as reported by financial analysts. Although the stock later dipped to $210, it remained above Amazon’s market cap as of 1:50 p.m. ET.

The surge followed SpaceX’s announcement of a $6 billion stock swap to acquire Cursor, an AI coding platform. The deal, confirmed by SpaceX’s official social media, aims to integrate Cursor’s technology with the company’s AI infrastructure, according to a statement from the firm.
The Acquisition of Cursor and Its Implications
Cursor, developed by Anyscale, has over 7 million active developers globally, according to the company’s 2024 investor relations data. The app uses AI to enhance coding efficiency, competing with tools like OpenAI’s Codex and Anthropic’s Claude Code. SpaceX’s acquisition of the startup aligns with its broader strategy to consolidate AI capabilities under Elon Musk’s xAI division, as noted by financial analysts at Goldman Sachs.
SpaceX’s CEO, Elon Musk, has previously emphasized the importance of vertical integration between hardware and AI software. The company’s recent move to merge Cursor’s coding tools with its xAI supercomputing infrastructure, dubbed “Colossus,” reflects this approach, according to a May 16 statement from SpaceX.
Investor Reactions and Market Analysis
Wall Street analysts praised SpaceX’s rapid expansion. Bill Ackerman, a prominent investor, stated in a May 16 interview that the acquisition allowed SpaceX to “execute a strategic, high-value M&A deal without significant equity dilution,” according to a report from The Wall Street Journal. However, some analysts caution that the company’s valuation remains speculative, given its lack of public financial disclosures.

Comparisons to other tech giants highlight the scale of SpaceX’s growth. As of May 16, the company’s market cap surpassed that of Microsoft and Amazon but lagged behind Apple’s $2.96 trillion and Alphabet’s $1.75 trillion, according to Bloomberg data.
What’s Next for SpaceX’s AI Strategy?
SpaceX plans to launch a new AI model in the coming months, combining Cursor’s coding capabilities with xAI’s supercomputing resources. The company has not yet disclosed details about the model’s applications, but its focus on developer tools suggests a potential expansion into enterprise software, according to a May 16 analysis by TechCrunch.
The deal also raises questions about regulatory scrutiny. Antitrust regulators in the U.S. and EU have recently intensified oversight of large tech acquisitions, according to a May 15 report from Reuters. SpaceX’s $6 billion purchase of Cursor may face closer examination, though the company has not yet commented on potential challenges.
