Rocket Lab: The Only One Building the Right RocketNarrow moat

The clearest evidence that launch prices are still not negotiable is what SpaceX charged this quarter. It flew 12 customer launches against 15 a year earlier, and launch services revenues rose to $1,130m from $1,000m¹. Fewer flights for outside customers, more money. Over nine months the same pattern holds more mildly, $2,108m of launch services revenue against $2,056m on 29 customer launches against 36². Nobody in this market is being undercut.

On the one measure that matters, Rocket Lab is the more interesting rival and much the smaller company. Electron carries about 300 kilograms, which is useful and irrelevant here. Neutron is designed to be reusable and to lift roughly 13,000 kilograms³ — the class Falcon 9 owns, and the only credible attempt to contest it.

What a second reflyable medium-lift rocket would do is not take volume. It would give a buyer something to quote against. SpaceX's cost advantage rests on being the only company recovering and reflying boosters at scale; the day a second one does, a satellite operator negotiating a launch has an alternative for the first time in a decade. Prices would move before any payload did.

The obstacles are the ones every launch company meets. Reuse is much harder than reaching orbit, and the learning curve SpaceX climbed cost it years and a great many destroyed boosters. Rocket Lab gets to watch someone else solve it, and has a fraction of the capital with which to copy the answer.

The size of that gap is now a published figure. SpaceX spent $1,225m on Space segment research and development in the September quarter alone, and $3,231m over nine months⁴. A challenger has to land a reusable medium-lift rocket while the incumbent spends that much every three months on the vehicle meant to replace the one it is being challenged on. Neutron is aimed at Falcon 9, and Falcon 9 is not where SpaceX is putting its money.

Two events, in order. A recovered Neutron booster, which would be a fine piece of engineering. Then the same booster flown again, which would change the economics of the industry. Until the second one happens, the number worth checking is SpaceX's launch services revenue: it is rising on falling flight counts, which is what a market with one supplier looks like from the inside.
