Why is RKLB stock up today?

Shares are higher after Rocket Lab reported qualified Neutron fairing and thrust-structure milestones, which reduce program risk. Sector sentiment also improved on chatter about a potential SpaceX IPO. Strong 2025 revenue and a $1.85 billion backlog add support. The combination sparked renewed interest in RKLB stock.

What is the Neutron rocket and why does it matter?

Neutron is Rocket Lab’s medium-class launch vehicle targeted for a Q4 2026 first launch. It aims to serve constellation deployment and national security missions. Each qualified milestone reduces engineering risk. Success would expand addressable market beyond Electron, potentially reshaping revenue mix and valuation for RKLB stock over the next few years.

Is RKLB stock cheap or expensive right now?

By traditional metrics it is expensive. The stock trades near 72.7 times sales and 25.6 times book, with negative earnings and free cash flow. Bulls argue growth, backlog, and Neutron can justify premiums. Bears focus on execution risk and cash burn. Results and milestones will drive the next re-rating.

What key dates should investors watch?
