After the U.S. stock market closed on May 8th, commercial aerospace company Rocket Lab (RKLB) announced a much better-than-expected Q1 2026 earnings report.
The financial report data showed that Rocket Lab's Q1 revenue reached $200.3 million, a significant year-on-year increase of 63.5%, higher than the expected $189 million; the Q2 revenue guidance was raised to $225-240 million, far exceeding analysts' expectations of $205 million. Although the operating loss of $56 million shows the company is still in a "cash-burning" mode, the adjusted gross margin has climbed to 43% (only 33.4% in the same period last year), indicating that the company's unit economics are significantly improving while scaling up — in simple terms, it's "burning money" more efficiently.
Boosted by the positive earnings report, RKLB rose nearly 7% after hours, and has gained a whopping 240% over the past year.
As SpaceX's century-level IPO approaches, commercial aerospace has become another hot theme in the U.S. stock market, with capital beginning to assign internet-level valuation imagination to the business of "building rockets." In this frenzy, apart from SpaceX, whose valuation is pointing to $1.75-2 trillion with significant pre-market premium, Rocket Lab, positioned as "the pure commercial aerospace stock most similar to SpaceX," has also become an alternative option in the eyes of many investors.
The 'Only Alternative' to SpaceX?
The reason Rocket Lab is seen as the current "only alternative" to SpaceX is that it is perfectly replicating the successful path already proven by SpaceX — first achieving commercial closure and reusable technology with a small rocket, then using a larger rocket to optimize costs and capture the core market.
Electron: The Dominant Player in the Small Rocket Segment
In the business of building rockets, PPT presentations are everywhere, but companies that can reliably launch rockets are few and far between. Currently, Rocket Lab's "Electron" is the world's only small launch vehicle achieving frequent and reliable commercial operation, and it is also the second most frequently launched rocket in the U.S., second only to SpaceX's "Falcon 9."
The "maturity" of Electron is reflected not only in its dozens of launch records and extremely high success rate but also in the implementation of its recovery technology. Rocket Lab has successfully retrieved the first-stage booster from the ocean multiple times and has even reused engines in subsequent launches. This mastery of engineering "reusability" technology is precisely the trump card weapon that allowed SpaceX to dominate the commercial aerospace market.
Neutron: The Falcon 9 Chaser
If the small rocket is Rocket Lab's entry ticket, then the medium-to-large rocket "Neutron" currently under development is the main engine for its charge towards a hundred-billion-dollar market cap.
Neutron is not simply a scaled-up version of Electron; it was designed from the outset with a strong "target" — to chase Falcon 9. Falcon 9 is currently the only commercially reusable medium-to-large rocket on the market, and SpaceX holds an absolute monopoly in this field.
The biggest significance of Neutron's emergence is that it is expected to become the world's only second option that can compete with Falcon 9, although its designed payload capacity (approx. 8-15 tons) is still slightly inferior to Falcon 9. However, in engineering logic, it attempts to achieve a curved overtaking of its predecessor through "late-mover advantages" — with unique designs like the HungryHippo fairing and Archimedes engine, Neutron aims to surpass Falcon 9 in efficiency regarding fairing recovery and engine reusability.
- Odaily Note: HungryHippo is Neutron's most significant design highlight. Unlike SpaceX, which needs to retrieve millions of dollars worth of fairing debris from the sea after each launch, Neutron's fairing adopts a fixed, non-separating design connected to the first-stage booster. When releasing the second stage, it opens like a "hippopotamus mouth," closes after deployment, and lands with the first stage for recovery. This means the fairing avoids the complex process of at-sea recovery and post-landing reassembly; it's ready for refueling immediately after landing.
Judging from the disclosed testing progress, Rocket Lab is rapidly narrowing the generational gap with SpaceX in medium-to-large launch capabilities.
"Building Rockets" plus "Building Satellites": Replicating SpaceX's Ecological Loop
Just as SpaceX has Starlink, Rocket Lab is also building its own "launch + manufacturing" dual-drive ecosystem. Rocket Lab's "Space Systems" business (covering satellite platforms, laser communication, solar arrays, etc.) currently accounts for nearly 70% of its total revenue. This means that even during Neutron's R&D phase, Rocket Lab can still generate substantial revenue by selling satellite components.
This kind of "full industry chain" business model is almost unique to Rocket Lab in the public market, before SpaceX's own potential listing.
Huge Valuation Gap: A Reflection of Reality and an Investment Opportunity
Currently, SpaceX's private market valuation is as high as $1.75 to $2 trillion, while Rocket Lab's market cap has just surpassed $45 billion. The huge valuation gap objectively reflects the real-world status difference between the two companies, but this is precisely where investors see the most attractive "odds."
In the current global commercial aerospace field, the only company that can stably achieve frequent launches, reusability, high payload capacity, and low costs is SpaceX. Falcon 9's cost advantage has reached a level that makes most competitors despair, and this advantage is gradually forming a terrifying positive spiral — the cheaper, the more launches; the more launches, the more data; the more data, the faster the upgrades; the faster the upgrades, the cheaper it gets... This moat built by scale, data, and pace has left countless latecomers in awe.
But Rocket Lab's opportunity lies in the fact that, currently, Neutron appears to be the most promising reusable medium-to-large rocket to catch up with Falcon 9's pace. "The only choice after SpaceX" — this single label alone is compelling enough. Once Neutron successfully completes its maiden flight, Rocket Lab's valuation logic will completely shift from "a small rocket company" to "the world's second platform company with medium-to-large reusable rocket capability," poised to capture a large number of commercial contracts from SpaceX's hands. Therefore, the current market enthusiasm for Rocket Lab is largely a bet on the success probability of Neutron.
At this point in 2026, with SpaceX having broken through the trillion-dollar valuation ceiling, Rocket Lab, with a market cap of only about 2.5% of SpaceX's, clearly has more room for upside imagination.
Biggest Risk: "Neutron" Hasn't Flown Yet...
But there's still one big suspense — Can Neutron actually fly on schedule?
According to the latest disclosure, Neutron's maiden flight is scheduled for the end of 2026. However, looking back at history, no new rocket launch has ever proceeded without delays. The aerospace industry has a harsh reality — a PPT rocket ≠ a real rocket.
Historically, many rockets never flew; many rockets blew up on their first flight; and many rockets failed in their cost-control designs. Neutron has yet to make its first flight. If Neutron's R&D progress encounters setbacks or its maiden flight is delayed, the current market cap will face severe pressure tests, and even the best story will be hard to continue telling.
