SpaceX is publicly traded as SPCX. Its Class A shares began trading on the Nasdaq Global Select Market and Nasdaq Texas on June 12, 2026, according to the company’s announcement. That listing makes it possible to compare SpaceX with public aerospace companies—but “aerospace” covers businesses with very different customers, revenue sources, capital needs and risks.
SpaceX is listed, but it is not a stand-in for every aerospace stock
SpaceX’s announcement says its registration statement became effective June 11, 2026, and that Class A shares began trading the following day under ticker SPCX. Do not confuse SPCX with Virgin Galactic’s ticker, SPCE. The company describes itself as a builder, but that is its own characterization, not an independent assessment of its investment merits.

A useful comparison starts by asking what each company sells and how it earns revenue. Rocket Lab is the closer comparison for launch services and space systems. RTX is an established aerospace and defense company, with a broader operating profile. Virgin Galactic focuses on human spaceflight. Their shares may all be discussed under the aerospace label, but they do not represent interchangeable businesses.
How the business models differ
| Company | Relevant business profile | What the comparison can show |
|---|---|---|
| SpaceX (SPCX) | Publicly traded Class A shares; consult the company’s current filings for its reported business mix and results. | A listed space company to evaluate using its own disclosures, not assumptions based on private-company history or reputation. |
| Rocket Lab (RKLB) | Its 2025 Form 10-K describes Electron, a family of spacecraft and development of Neutron. | A more relevant launch and space-systems comparison, while still a distinct company with its own products and economics. Rocket Lab’s 2025 Form 10-K |
| RTX (RTX) | An established aerospace and defense company. Its investor filing page identifies its 2025 Form 10-K as filed February 6, 2026, for the year ended December 31, 2025. | A comparison for a different, broader aerospace and defense exposure. Read the filing itself before drawing conclusions about segments or results. RTX SEC filings |
| Virgin Galactic (SPCE) | Its 2025 Form 10-K describes human spaceflight for private individuals, researchers and government agencies. The filing says commercial service had been paused in mid-2024 and describes a 2026 restart schedule as management’s expectation. | A human-spaceflight case with materially different operations and financing demands—not a proxy for launch or defense businesses. Plans can change; review its latest disclosures. Virgin Galactic SEC filings |
The distinction matters because a launch provider, a satellite or spacecraft systems business, a defense supplier and a passenger spaceflight operator can face different demand cycles, contract structures and development risks. Similar headlines or share-price moves do not make their underlying economics comparable.
#1 Best Overall
Compare financial performance on the same basis
Use each company’s latest annual and quarterly reports, and align the periods before comparing figures. Fiscal years, segment definitions and reporting dates may differ. A table built from mismatched periods can create a false impression of relative growth or profitability.
For each company, examine:
- Revenue by segment and how much comes from recurring services, product sales or contracts.
- Gross margin, operating income or loss, and cash from operations.
- Capital expenditure, cash and debt, alongside the company’s stated financing needs.
- Backlog and contract terms, where reported, including how much is funded and when revenue is expected.
- Customer mix: commercial, government and defense exposure, plus any disclosed concentration risks.
Virgin Galactic’s 2025 Form 10-K reported net losses of $278.9 million for 2025 and $346.7 million for 2024. Those are company-reported figures for the stated fiscal years, not a current run rate or a direct measure of how it compares with SpaceX, Rocket Lab or RTX. Its paused commercial service and management’s stated restart expectations also make it especially important to read the latest filing rather than treat an earlier schedule as a guarantee.
Rank #2
Rocket Lab’s 2025 Form 10-K reported an aggregate market value of $14.9 billion for shares held by non-affiliates as of June 30, 2025. That dated SEC cover-page measure is not its current market capitalization and should not be used as a current valuation comparison.

There is no sound “cheaper stock” conclusion without comparable market data and financial periods. For a date-matched comparison, determine each company’s market capitalization and enterprise value, then relate those measures to financial metrics that fit its business and maturity—such as revenue, earnings, cash flow or backlog. Enterprise value and market capitalization are not interchangeable, and backlog is not the same as recognized revenue or profit.
Rank #3
For every ratio, record the market-data date, reporting period and definition used. A high revenue multiple may reflect expectations, but it does not establish that a share is overvalued; a low one does not prove a bargain. If a company has losses or negative cash flow, explain that an earnings-based multiple may not be meaningful rather than forcing a ranking.
Assess execution, regulation and governance
Space and aerospace businesses can depend on complex development programs, reliable operations, customer approvals and regulatory permissions. Compare launch cadence, system reliability, development milestones and capital intensity using current company filings and announcements. Treat forward-looking schedules as plans or management expectations, not completed achievements.
Governance deserves its own review. SpaceX’s listing announcement establishes the ticker and trading dates, but it does not provide enough detail to assess voting rights or shareholder control. Read the full prospectus and SEC filings for share-class terms, voting power, board accountability, conflicts and the rights attached to the shares being offered. Do not infer those terms from a ticker or a headline about the listing.
A practical checklist before comparing or buying
- Confirm the security. Check the ticker, exchange, share class and listing documents. SpaceX is SPCX; Virgin Galactic is SPCE.
- Define the comparison. Separate launch and space systems, aerospace and defense, and human spaceflight rather than treating them as one peer group.
- Open the latest filings. Use annual and quarterly reports from each issuer, and note filing dates, fiscal periods and segment definitions.
- Build a normalized financial view. Compare revenue mix, profitability, cash flow, capital spending, debt, cash and financing needs for aligned periods.
- Use same-day valuation inputs. Record the date and definitions for market capitalization, enterprise value and any revenue, earnings, cash-flow or backlog measures.
- Read risks and rights. Review customer concentration, execution and regulatory risks, and the prospectus terms governing votes and shareholder protections.
- Recheck before acting. Prices, filings, schedules and company disclosures change; consult current issuer documents and market data rather than relying on stale figures or a competitor’s share-price move.
What the comparison can—and cannot—tell you
Rocket Lab is the more relevant public comparison for launch and space systems, while RTX and Virgin Galactic help illustrate different aerospace exposures. That is a comparison of business profiles, not a claim that the companies have equivalent risks, valuations or prospects. The decision depends on current disclosures and a valuation method suited to each company—not on the prominence of an IPO or the broad label “aerospace.”
