Space Exploration Technologies (SpaceX) briefly exceeded Amazon’s market capitalization on June 16, reaching an intraday high of $2.97 trillion. This valuation occurred as SpaceX shares traded at $225.29, with 13.17 billion fully diluted shares outstanding. Amazon, during the same period, traded 10.6% below its own $2.96 trillion market cap peak.
The market positions shifted in the subsequent days. As of June 18, Amazon had regained its lead with a $2.62 trillion market capitalization, while SpaceX’s valuation stood at $2.36 trillion. This fluctuation highlights the dynamic nature of the trillion-dollar club on Wall Street.
SpaceX’s initial public offering (IPO) momentum marked a significant event for the company. Its brief ascendancy over Amazon placed it among the highest-valued public companies. The company’s market debut has drawn considerable attention from investors and market observers.
Comparing SpaceX to established technology giants, Amazon generated $723 billion in revenue and $90.8 billion in net income over the last four quarters. Tesla, a corporate cousin to SpaceX, reported $98 billion in sales and $3.9 billion in net income during the same period. These figures provide a financial context for SpaceX’s performance.
SpaceX reported a net loss of $8.69 billion on revenues of $19.3 billion over the last four quarters. These financials encompass a full year of its rocket launch and Starlink satellite internet operations. They also include approximately two months of the xAI artificial intelligence company, which merged into SpaceX at the end of February 2026. The X social media business also merged with xAI in February 2026.
The exact contribution of each segment to SpaceX’s overall business remains unclear. The company has not yet reported quarterly earnings, and its S-1 filing provided limited segment-specific financial details. The fundamental rocketry operations are characterized by their lumpy and unpredictable revenue generation.
The merger of xAI into SpaceX, occurring one month into Q1 2026, appears to have increased expenses more than revenues. Building data centers and operating artificial intelligence functions within them are costly endeavors, impacting the company’s financial results.
Most stock data services currently lack price-to-earnings (P/E) or price-to-sales (P/S) valuation ratios for SpaceX. Profit-based metrics are not considered meaningful while the company is reporting net losses.
The future trajectory of SpaceX in the public market will depend on its ability to stabilize and grow its diverse operations, including Starlink and its AI ventures. Investors will be watching for more detailed financial reporting to assess the performance of its various segments.
Market capitalization rankings could continue to shift among the largest companies. The ongoing performance of both SpaceX and Amazon, alongside other trillion-dollar entities, will be a key area of focus for market analysts.
