SpaceX's historic post-IPO run is not slowing down, with shares surging again on Tuesday to briefly surpass Microsoft and overtake Amazon by market cap. Just days after its huge public debut, the Elon Musk-led company has become one of the world's most valuable publicly traded businesses as investors pile into its expanding AI and space ambitions.
The latest rally has pushed SpaceX more than 60% above its $135 IPO price, lifting its valuation to nearly $2.9 trillion. While the move has fueled comparisons with Big Tech giants, it has also sparked debate over whether investor enthusiasm is running ahead of the company's current financial fundamentals.
AI Acquisition Supercharges Investor Optimism
A major catalyst behind Tuesday's surge was SpaceX's announcement that it will acquire AI coding platform Anysphere, the developer of Cursor, in a $60 billion all-stock transaction expected to close later this year. Cursor has become one of the fastest-growing AI developer platforms, offering code generation, autocomplete, and AI-powered programming assistants for enterprise customers.
The acquisition expands SpaceX's presence beyond launch services and satellite connectivity, giving investors another reason to view the company as an AI infrastructure leader rather than a traditional aerospace business. The deal also highlights management's strategy of combining space technology, communications networks, and enterprise AI software into a broader tech ecosystem.
Passive Investment Flows Add More Fuel
Beyond the acquisition, another powerful force is supporting the stock's momentum: index inclusion. With fast-track additions expected across major benchmarks, including the Nasdaq 100 and other widely followed indexes, passive investment funds and exchange-traded funds will soon be required to purchase millions of shares. Analysts believe those automatic inflows could create sustained buying pressure over the coming weeks. SpaceX also announced that underwriters exercised the IPO's greenshoe option, increasing total proceeds to roughly $85.7 billion and marking one of the largest capital raises ever completed by a public company.
Options Trading Brings More Volatility
Tuesday also marked the launch of listed options trading for SpaceX shares, giving investors new ways to speculate on the stock's future direction. Options activity often amplifies price swings as market makers hedge positions and traders increase leverage. Combined with a relatively limited public float and exceptionally strong retail demand, the new derivatives market could contribute to heightened volatility as price discovery continues. Trading volumes have already been extraordinary, with billions of dollars changing hands and retail investors remaining among the stock's most aggressive buyers.
Valuation Debate Grows
Despite the enthusiasm, many analysts caution that SpaceX's valuation is now approaching companies with significantly larger revenue bases and established profitability. The company generated approximately $18.7 billion in annual revenue while reporting a consolidated net loss following the integration of its AI businesses. By comparison, peers such as Microsoft, Apple, and Alphabet generate hundreds of billions of dollars in annual revenue alongside substantial profit margins.
Supporters argue that today's valuation reflects future growth opportunities across satellite communications, launch services, defense contracts, AI software, and autonomous technologies rather than current earnings power. Skeptics counter that expectations have become extremely ambitious for a company that is still investing heavily in growth.
Retail Investors Continue Driving Momentum
Retail participation remains one of the defining features of SpaceX's early trading history. Strong buying interest has helped propel shares sharply higher each session since the IPO, with social media enthusiasm and AI optimism creating a powerful momentum trade. At the same time, institutional investors are beginning to increase exposure ahead of expected index additions, creating a rare combination of retail speculation and passive fund demand that has accelerated the stock's rise.
Looking Ahead
SpaceX enters the next phase of its public life with enormous momentum but equally high expectations. Investors will be watching the progress of the Anysphere acquisition, upcoming index inclusions, and whether the company can translate its AI ambitions into meaningful revenue and profitability. With limited public float, active options trading, and growing institutional interest, volatility is likely to remain elevated as the market determines whether SpaceX deserves its place alongside the world's most valuable technology companies.
