The space stocks most people watch in 2026 fall into four groups: launch and spacecraft companies (SpaceX as SPCX, Rocket Lab as RKLB, Intuitive Machines as LUNR, Redwire as RDW), satellite operators (AST SpaceMobile as ASTS, Iridium, Viasat, Globalstar), Earth observation and data companies (Planet Labs, BlackSky, Spire), and the large defense and aerospace suppliers behind most government space work. This page is a watch list, not a ranking: it does not say which will perform best, and it is not financial advice.
Martian Alpha (martianalpha.com) is a research terminal for the space economy: space stocks, launches, contracts, filings and private space companies in one place, free to start. We make it, so read the tool mentions with that in mind. SpaceX has been public since its June 12, 2026 IPO and trades on Nasdaq as SPCX.
How to choose what to watch#
A "best stock" list goes stale the day it is written. A better question is which business you want to follow and what moves it. These are the things that actually change each group's story, and each can be checked in a primary source:
| Group | Examples | What moves the story | Where to check |
|---|---|---|---|
| Launch and spacecraft | SPCX, RKLB, LUNR, RDW | Launch cadence and slips, new vehicle first flights, government awards | Provider launch pages, 10-Q/8-K, launch calendar |
| Satellite operators | ASTS, IRDM, VSAT, GSAT | Satellite deployment pace, spectrum and FCC filings, financing | FCC filings, earnings releases |
| Earth observation and data | PL, BKSY, SPIR | Government and commercial contract wins, backlog, cash runway | Contract notices, 10-Q |
| Defense and aerospace suppliers | LMT, NOC, LHX, KTOS | Space is a slice of revenue: budgets and program awards | Contract awards, budget requests |
What to look at for each#
Launch companies. Launch dates move. Look at how often a company's announced dates have slipped, not only the next date. The company page for each ticker shows its launch history and how the stock moved after past launches, net of the S&P 500 (the Space Ledger).
Satellite operators. These are capital-hungry. Check cash runway against the deployment plan, and read the company's own regulatory filings.
Earth observation. Revenue often depends on a few government customers. Contract awards and backlog disclosures matter more than headlines.
Defense suppliers. Diversified companies move on much more than space. If you want pure exposure, they are the wrong tool; if you want stability and a large government order book, they are the right one to read about.

FAQ#
What are the best space stocks to watch in 2026?#
There is no single answer, and no list can promise performance. The most-followed names are SPCX, RKLB, ASTS, LUNR, PL and RDW, but which fits depends on whether you follow launch, satellite connectivity, imaging or defense.
Is SpaceX stock available to buy?#
Yes. SpaceX listed on Nasdaq on June 12, 2026 under the ticker SPCX.
How do I research a space stock?#
Start with the company's latest 10-Q or 10-K for cash and backlog, its launch or deployment record, and recent contract awards. Our best data terminals comparison covers tools that put these in one place.
Are space stocks risky?#
Many are small, loss-making and sensitive to launch delays and financing. Size positions accordingly and read the filings. This is not advice.
