Neutron is a partially reusable medium-lift two-stage rocket being developed by Rocket Lab. It has been scheduled to launch in 2025, but might slip to the further date.
This market will be resolved when Neutron rocket launches for the first time. For the purposes of this question, "launch" should involve the countdown reaching 0 and the rocket leaving the pad. I.e. Astra sideways launch would count, but an explosion right on the pad wouldn't.
I do not bet on my own markets.
If there is sufficient interest in this market, I'll add further markets about other milestones for Rocket Lab rockets.
For anyone trading the 2027 buckets: the October 14 8-K only says the first launch "is now anticipated to shift into next year", with no quarter given. The next chance for a tighter date is the Q3 call on Monday, November 9, after the close. Funding is not the constraint: Rocket Lab sold 29.3M shares for $1.944B between August 13 and September 15, though that raise is earmarked for the Iridium deal.
