Is It Too Late to Invest in Space Stocks After Artemis 2 Already Launched? I Dug Into the Numbers and Found Something Surprising
Yesterday, April 1st 2026, Artemis II lifted off from Kennedy Space Center. Four astronauts headed toward lunar orbit. First crewed moon mission since 1972. Fifty-four years in the making.
And here you are, reading this right now.
“Did I miss it?”
I had the same thought. So I went down the rabbit hole. Pulled up every earnings report, every backlog number, every analyst target I could find. And what I found honestly surprised me.
Rocket Lab is up 279% over the past year. Lockheed Martin gained 38% just in 2026. Seeing those numbers after the fact stings. I get it. That familiar feeling of “I should have bought earlier” hits different when rockets are literally flying on your screen.
But then I stumbled across a pattern that changed my whole perspective.
Amazon didn’t make its biggest millionaires at IPO. It made them after the 90% crash in 2001. Tesla kept tripling even after the S&P 500 inclusion “news” everyone thought was the peak.
The launch was a beginning. Not an ending.
The “Sell the News” Trap and What I Found Hiding Behind It
On launch day, space stocks popped about 2% in premarket trading. RKLB, LUNR, ASTS all moved up together.
But the week before? On March 24th, when NASA announced program restructuring, Intuitive Machines, Rocket Lab, Firefly Aerospace, and Redwire dropped an average of 5%.
That is the classic “buy the rumor, sell the news” cycle playing out in real time.
Most retail investors get crushed by this pattern. They buy on headlines. Prices dip. Panic sets in. They sell at the worst possible moment.
I kept digging though. And when I flipped that pattern upside down, something clicked.
Every single “sell the news” dip in this sector happened right before the next leg up. The dip after the NASA restructuring announcement? That was the last cheap entry before launch day rallied everything back up.
The pattern kept repeating.
The Part Nobody Is Talking About and Why It Changes Everything
Here is what really caught my attention when I mapped out the full timeline.
Artemis II was a lunar orbit test flight. Nobody landed on the moon. The crew flies around and comes home. That is it. The actual lunar landing? That is still years away.
NASA’s official schedule looks like this.
Artemis III in 2027 focuses on integrated systems testing and docking practice. Artemis IV in early 2028 is the first crewed lunar landing in 52 years. Artemis V in late 2028 is the second landing. Then comes the Gateway space station, a permanent outpost orbiting the moon. (NASA official announcement)
Now zoom out to the big picture numbers.
Morgan Stanley projects the global space economy will grow from $469 billion today to $1.8 trillion by 2035. (ARK Invest and Motley Fool coverage) That is roughly 4x growth in under a decade. The Artemis program alone carries a $93 billion price tag.
When I saw those numbers side by side, it hit me. Feeling “too late” after Artemis II is like watching the first iPhone launch in 2007 and concluding the smartphone market was already over.
We are at about 26% of where this market is headed.
What I Found When I Looked at Who Actually Made Money
I stopped reading opinions and started tracking what actually worked. Here is what I pieced together from public filings, analyst reports, and earnings calls.
The Steady Foundation Players
Lockheed Martin builds the Orion crew capsule. The one that literally launched yesterday. Their Space segment posted $3.16 billion in Q4 2025 revenue, up 8% year over year. Their backlog hit a record $194 billion. They have raised their dividend 23 straight years. Up 38% year to date. (247WallSt breakdown)
Northrop Grumman is building HALO, the core module for the Gateway lunar space station. Backlog reached $95.7 billion. Stock gained 65% over the past year. Their book-to-bill ratio is 1.10, meaning they are winning new contracts faster than they can fulfill existing ones.
The common thread here is that space is only part of their revenue. Defense backlogs cushion the downside. These are the names that let you sleep at night.
The High-Growth Pure Plays
Rocket Lab grew revenue 38% in 2025 and backlog surged 73% to $1.85 billion. Non-GAAP gross margin expanded to 44.3% in Q4. But they are still burning cash. Negative $321.8 million in free cash flow for 2025. Beta of 2.2, which means they swing more than twice as hard as the overall market. (Motley Fool analysis)
Intuitive Machines landed a $4.8 billion Near Space Network contract with NASA. They ran the communication and tracking systems for Artemis II. They also build lunar landers. (TipRanks coverage)
These are the ones that could 3x or get cut in half. Eyes wide open.
The Quiet Long-Term Card
BWX Technologies is developing nuclear propulsion systems for deep space travel. This is the technology that makes crewed Mars missions realistic by cutting transit time by months. Revenue grew 18% in 2025 to $3.2 billion. Backlog jumped 50% to $7.26 billion. Stock doubled over the past year. (247WallSt)
The Elephant in the Room
SpaceX filed for what could be the largest IPO in history. Potential valuation over $1.75 trillion. Targeting roughly $75 billion in fundraising, possibly by June 2026. Reports suggest up to 30% of shares could be allocated to retail investors. (Reuters)
This is not just one stock going public. It is a liquidity event for the entire sector. SpaceX IPO anticipation alone has been moving every space-related name on the board.
The Mechanical System I Built After Seeing All of This
Feelings aside. Here is the framework I assembled from everything I found.
The 3-Tier Split
Stable foundation at 50 to 60% of the portfolio. Names like LMT, NOC, and L3Harris. Dividend income plus massive backlog protection.
Growth positions at 25 to 35%. Names like RKLB, LUNR, and ASTS. High ceiling, high volatility. Accept the ride or stay out.
Future bets at 10 to 15%. BWXT for nuclear propulsion. Cash reserved for SpaceX IPO when it opens.
The Event Calendar Buy System
The Artemis program drops major catalysts every few months. Each one triggers a volatility spike. The “sell the news” dip after each event has consistently been a buying window.
Remaining 2026 calendar includes the Artemis II crew return in mid-April, the expected SpaceX IPO around June, and the Rocket Lab Neutron rocket launch targeted for Q4.
In 2027, Artemis III reignites the lunar landing narrative. In 2028, Artemis IV puts humans back on the moon.
Buy in pieces around these dates. Not all at once. Not on headlines.
The ETF Starting Point
ARKX from Cathie Wood’s ARK Invest covers the space economy broadly. In 2025, ARK’s flagship fund returned 45.4%. (Investors.com) If picking individual stocks feels overwhelming, starting with an ETF and gradually shifting into individual names as you learn more is a path that has worked for a lot of people.
The Hard Rule on Exits
For high-volatility names like RKLB and LUNR, a mechanical stop at negative 20%. For stable names like LMT and NOC, negative 10%. Set it and do not negotiate with yourself. The moment feelings enter the equation, accounts start melting.
Here Is What I Keep Coming Back To
One number sticks with me.
In 2025, satellite stocks surged over 200%. (CNBC) That money already landed in someone else’s account. Cannot rewind that.
But a $469 billion market heading to $1.8 trillion means we are still standing in the early chapters.
Artemis II confirmed the story is real. Artemis III, IV, and V are still ahead. The Gateway station is still being built. The SpaceX IPO has not happened yet. NASA’s $20 billion moon base budget is still being deployed.
The rocket that launched yesterday was not your rocket. Your rocket is the next one. And the launchpad is already under construction.
You did not miss it. You just had not started looking yet. Now you have.
Q&A
Q1. Did space stocks already peak after the Artemis 2 launch?
The launch day rally was only about 2% in premarket. The real catalysts are still ahead. Artemis III in 2027, Artemis IV lunar landing in 2028, and the SpaceX IPO expected by June 2026 are all larger potential price drivers than the Artemis II launch itself. Morgan Stanley forecasts the space economy growing from $469 billion to $1.8 trillion by 2035, which means the sector is still in early innings.
Q2. What is the safest way to start investing in space stocks with a small budget?
The ARKX ETF from ARK Invest offers broad exposure to the space economy without the risk of picking a single stock. For those who want individual names, Lockheed Martin and Northrop Grumman carry massive defense backlogs that cushion downside while still giving direct Artemis program exposure. Starting with 50 to 60% in stable names and building from there is the approach that showed up most consistently in the research.
Q3. Is the SpaceX IPO worth waiting for?
SpaceX is preparing what could be the largest IPO in history at a potential $1.75 trillion valuation. Reports indicate up to 30% of shares could go to retail investors. Beyond the stock itself, the IPO is expected to pour liquidity into the entire space sector, potentially lifting related names across the board. Setting aside 10 to 15% of your space allocation for this event showed up as a common strategy among analysts.
Q4. How do I avoid buying at the top right after a big headline?
The "buy the rumor, sell the news" pattern repeated consistently across every major Artemis milestone. Stocks rallied before each event and dipped afterward. Waiting 1 to 2 weeks after a major headline and buying during the post-news dip was the pattern that aligned with the strongest entries in the data. Setting mechanical buy points around the event calendar rather than reacting to headlines removes the emotional trap.
Q5. Which space stocks have the most growth potential over the next 3 years?
Rocket Lab grew revenue 38% in 2025 with a backlog surging 73%, but remains unprofitable with high volatility. Intuitive Machines holds a $4.8 billion NASA contract and operates lunar infrastructure. BWX Technologies is developing nuclear propulsion for deep space missions with revenue up 18% and backlog up 50%. Each carries different risk levels. The article lays out a tier system to match these to your personal risk tolerance rather than chasing the hottest name.
