Rocket Lab's stock climbed nearly 2% overnight Wednesday as the company pointed to a structural shift in its biggest competitor: SpaceX is no longer a launch company first. Starlink generated $11.4 billion in revenue last year - 61% of SpaceX's $18.7 billion total - up roughly 50% year over year. Launch services... are now projected to account for only 20–25% of SpaceX revenue in 2026. That is the shift Rocket Lab CEO Peter Beck has been describing when he says Neutron has landed in a "nice spot." Put plainly: the monopolist is becoming something else, and the gap it leaves behind is where RocketLab's medium-lift rocket is designed to operate.
But the headline about Neutron and SpaceX's distraction tells only half the story. The more important reality is that RocketLab is already not primarily a launch company either.
Space Systems Is the Real Business
Rocket Lab reported record Q1 2026 revenue of $200.3 million - up 63.5% year over year. Of that, Space Systems - the segment that builds satellite components, propulsion systems, and solar arrays - generated $136.7 million. Launch services, including the Electron rocket fleet, brought in $63.7 million. Space Systems is now 68% of the company's revenue, a proportion that has only grown as the business matures.
This is what separates RocketLab from every other company in the small-satellite launch space. It is not a rocket company that adds hardware sales on the side. It is a vertically integrated space hardware manufacturer that happens to also launch rockets. The company has the world's only vertically integrated solar array manufacturing capability for satellites, and its propulsion components and flight software are sold to third-party satellite operators who have nothing to do with RocketLab's own launch business.
The backlog confirms the structural shift. As of Q4 2025, the total contracted backlog was approximately $1.85 billion - and 74% of it is tied to Space Systems, not launches. The recent $90 million U.S. Space Force contract to build and operate two geostationary satellites added directly to this pipeline. Revenue growth is being driven by people who buy satellite hardware, not people who buy launch rides.
Neutron's Window - And Its Timing Risk
On the launch side, the argument is more nuanced but still real. SpaceX's Starship is designed for massive payloads - it belongs in the super-heavy category and is optimized for Mars ambitions and mega-constellation replenishment. Neutron is a medium-lift reusable rocket, designed for the 5,000-kilogram orbital class. It doesn't compete with Starship on the same dimension. It competes with Falcon 9, and it enters the market at a moment when SpaceX's organizational focus and engineering bandwidth are increasingly pulled toward Starlink monetization and Starship development.
That creates the "nice spot" Beck references. National security launch - specifically the U.S. Space Force's $5.6 billion National Security Space Launch program - requires redundancy. The Pentagon doesn't bet on a single provider for classified payloads, regardless of how dominant that provider is in commercial launches. Neutron has been formally on-ramped to the NSSL program, and in May 2026, RocketLab announced its biggest launch deal yet:... five dedicated Neutron launches and three Electron flights.
The question isn't whether Neutron has a market. The question is whether it launches in Q4 2026 as promised, or whether the delay pattern continues. The debut was pushed from 2025 to 2026 after a test stand anomaly in late 2025. Beck restated in April that the rocket is "on track" for a fourth-quarter debut, but in rocket development, on-track declarations have a long history of compressing timelines until physics pushes back.
The Stock Is Pricing a Working Neutron
Rocket Lab's stock hit an all-time high of $150.23 in late May before pulling back to the $103–$117 range where it's trading now. The stock has roughly quadrupled from a year ago, priced on the assumption that Space Systems growth continues accelerating and Neutron actually launches on time.
The growth math supports the run. Full-year 2025 revenue reached $602 million, up 38% from $436 million in 2024. Q1 2026 at $200 million puts the company on a run rate of roughly $800 million - a trajectory that would make RKLB the fastest-growing publicly traded space infrastructure company by a wide margin. GAAP gross margin in Q1 was 38.2%, with non-GAAP gross margin at 43%, indicating the Space Systems mix shift is improving profitability as volume scales.
However, the return curve from here is back-half weighted. Much of what justifies a higher valuation - Neutron in operational service, recurring government launch contracts, Space Systems extending into satellite manufacturing - doesn't show up on the income statement until 2027 at the earliest. The stock is pricing a working Neutron and a Space Systems business that keeps accelerating. If either slips, the multiple compresses.
Where the Capital Goes
The debate is not whether RocketLab has a viable thesis. It does - and it's stronger than the generic "SpaceX alternative" narrative suggests, because Space Systems is the durable business and launches are increasingly the proof-of-concept that wins hardware contracts. The question is timing and allocation.
I believe the long-term case is intact. Space Systems at $400 million in full-year 2025 revenue, with 74% of the backlog, represents a company that is building real infrastructure moats in satellite components and propulsion - areas where no single competitor has the vertical integration RocketLab has developed. Neutron entering the NSSL program gives the launch business a floor of government demand that doesn't require beating SpaceX, only complementing it. SpaceX becoming a Starlink company is a structural tailwind that isn't going away.
But I would treat the current position differently depending on entry point. At near-all-time highs, the stock front-loaded a lot of the Neutron success story. A position sized for conviction - not speculation - makes sense if you believe in the 2027–2028 inflection when Neutron transitions from prototype to revenue generator. If you need the return in the next 12 months, the timing is tight. Neutron's first launch still hasn't happened, and the Space Systems growth story, while real, has been widely followed by the market already.
The break condition is clear: if Neutron slips past Q4 2026 again, or if Space Systems growth decelerates from the 60%+ range, the stock's current trajectory changes. Until then, the thesis is working - it just needs execution to catch up to the price.
