Palantir vs. SpaceX: A Financial and Stock Comparison

Not affiliated with Palantir Technologies Inc. This page is an independent explainer based on publicly available sources. Nothing here is financial advice. A note on timing: SpaceX only became a publicly traded company in mid-2026 — a genuinely recent, still-developing situation — so figures here reflect a much shorter public trading history than Palantir's, and will change faster than usual as more data becomes available.

For most of its history, comparing Palantir to SpaceX meant comparing a public stock to a private company's estimated valuation. That changed in June 2026, when SpaceX completed the largest initial public offering in history — meaning this is now a genuine stock-to-stock comparison for the first time.

SpaceX's IPO, briefly

SpaceX priced its IPO at $135 per share on June 12, 2026, raising roughly $75 billion and listing on the Nasdaq under the ticker SPCX. Shares closed their first trading day around $161, up about 19%, valuing the company above $2 trillion — making it, on paper, larger than Palantir by a wide margin from day one. SpaceX also secured early inclusion in the Nasdaq-100 index, though not the S&P 500. CEO Elon Musk retained roughly 82–85% of voting power after the listing, meaning public shareholders have limited influence over company decisions compared to a more conventionally structured public company.

Scale: SpaceX is larger, but by a different kind of business

SpaceX reported full-year 2025 revenue of roughly $18.6–18.7 billion, more than four times Palantir's roughly $4.47 billion for the same year. But the composition is very different: SpaceX's revenue mix has shifted heavily toward Starlink, its satellite internet business, which alone generated $11.4 billion in 2025 (61% of total revenue) and has become the company's core profit center, even as SpaceX's launch business and newer ventures continue to require heavy investment.

Profitability: a real, important difference

This is the sharpest contrast between the two companies. Palantir is solidly profitable on a GAAP basis, with net income of $871 million and $1.062 billion in Q1 and Q2 2026 respectively, detailed further on our key financial metrics page. SpaceX, by contrast, posted a GAAP net loss of nearly $5 billion for full-year 2025, reflecting heavy ongoing spending on Starship development, satellite deployment, and its February 2026 acquisition of xAI — even though Starlink itself is profitable on its own, generating $4.4 billion of operating profit in 2025.

Valuation multiples

SpaceX's IPO valuation implied a price-to-sales multiple in the range of 72 to over 90 times, depending on which revenue estimate is used — a multiple one analysis noted exceeds even Nvidia's roughly 30-times-revenue multiple, and sits in a similar rich territory to Palantir's own price-to-sales ratio, which has ranged from roughly 46 to 69 times revenue across 2026 reporting.

A very short public trading history

As of this writing, SpaceX has only been a public company for a few months, compared to Palantir's several years of public trading since its 2020 direct listing. That matters directly: SpaceX's stock has already shown significant volatility in that short window — one source described a roughly 50% correction from its post-IPO highs — but there simply isn't enough public trading history yet to draw the kind of longer-term pattern analysis we can offer for Palantir on our stock volatility page.

The genuinely different bet each stock represents

Even beyond the numbers, these are different kinds of investments. Palantir is a software company selling data-integration and AI tools to governments and enterprises, with the margin structure that implies. SpaceX is a capital-intensive aerospace and telecommunications company — building rockets, satellites, and now AI infrastructure through xAI — where profitability depends on successfully scaling extremely expensive physical infrastructure, a fundamentally different risk profile than Palantir's software business.
