SpaceX market capitalisation exceeds $2.6 trillion
Space Exploration Technologies Corp. (SpaceX) has achieved a historic market valuation of $2.66 trillion, positioning itself as the sixth most valuable publicly traded company in the United States following its recent stock market debut.
SpaceX achieved a $2.66 trillion market capitalisation as its shares climbed to $201.80, representing an approximate 35% increase from its initial public offering (IPO) opening price on June 12, 2026.
The aerospace firm has secured the sixth position among the most valuable US enterprises, trailing only technology giants Nvidia, Alphabet, Apple, and Microsoft.
Analysts have cautioned regarding potential overvaluation risks, pointing to exceptionally high price-to-sales (P/S) and price-to-book (P/B) ratios.
Standard price-to-earnings (P/E) metrics remain unavailable due to the company's unprofitability, marked by a substantial net loss of $4.94 billion disclosed in its 2025 annual report.

The subsequent data, which illustrates the composition of US equities by market capitalisation, highlights the company's rapid ascent into the top tier of publicly traded entities, making it the most valuable firm within the industrial sector. According to data compiled by Finviz at the close of today's trading session, SpaceX has risen to sixth place in the valuation rankings of all listed companies in the United States. With this milestone, its market value now surpasses that of prominent corporations including Amazon, Broadcom, Meta, Tesla, and Berkshire Hathaway. Consequently, this capitalization places the company among the elite corporate entities worldwide. Above the SpaceX valuation tier, only Nvidia, Alphabet, Apple, and Microsoft maintain higher market caps.

Overvaluation risks in SpaceX
Nevertheless, while SpaceX continues to accumulate market value and command the attention of global market participants, significant overvaluation risks persist, prompting caution from analysts who believe these metrics could pose long-term challenges.
According to data provided by Yahoo Finance, the company's trailing price-to-sales (P/S) ratio stands at an elevated 130x, while its price-to-book (P/B) ratio has reached 72x. These specific valuation multiples are considerably higher than the averages observed in the broader aerospace and industrial sectors. They also exceed historical whole-market benchmarks when compared to past major IPOs where foundational valuation metrics were significantly more moderate.
Finally, a traditional price-to-earnings (P/E) ratio cannot be calculated because the corporation has yet to generate positive quarterly net income. The underlying financial statements reveal that the firm recorded a net loss of $4.94 billion in its 2025 annual fiscal report.
