Rocket Lab’s Neutron medium-lift rocket faces a narrowing window for a 2026 debut, with recent Spaceflight Now reporting highlighting ongoing stage tank production and integration work aligned only for a Q4 pad delivery. Prior delays from a January 2026 propellant tank rupture during testing, combined with extended Archimedes engine qualification, have already pushed the target from earlier timelines, a pattern common in new reusable launch vehicle development. Traders assign an 86.5% implied probability to “No” by December 31 because first flights of comparable vehicles routinely slip amid hardware and regulatory hurdles, even as the company maintains its late-2026 goal. Key near-term catalysts include further tank builds, hot-fire tests, and launch site preparations at Wallops that could either compress or extend the schedule.

The outcome of any launch will be corroborated by examining official video provided by Rocket Lab (https://www.youtube.com/@RocketLabCorp), as well as secondary video feeds and/or written reports if necessary.
Any subsequent anomaly (e.g., explosion or failed ascent) after the initial liftoff will have no bearing on the outcome. Any name change or rebranding of the Neutron vehicle will have no bearing on the market’s resolution.
