Does the SpaceX IPO Mean You Should Ditch Rocket Lab?

SpaceX has gone public at a $2.1 trillion market cap, while Rocket Lab has fallen 32% from its highs and still trades at roughly $60 billion, or 89x sales. The article argues both names are richly valued, with SpaceX generating $18 billion in 2025 revenue and Rocket Lab producing $680 million over the last 12 months. The key takeaway is a cautious, valuation-driven view: avoid chasing either stock despite strong long-term growth narratives tied to AI and space infrastructure.

Analysis

The real market signal here is not “which space stock wins,” but that public-market capital is treating launch capacity as a narrative asset class again. That tends to compress dispersion in the short run: secondary names with weak free-cash-flow visibility get repriced on momentum rather than fundamentals, while the obvious proxy winner is the larger platform with adjacent AI optionality. In that regime, satellite internet and launch-adjacent spend can keep pulling valuation higher even before core aerospace economics justify it.

Rocket Lab’s setup is more fragile than the headline multiple implies. The market is implicitly paying for a successful Neutron execution plus a multi-year transition from niche launcher to integrated space platform, but every delay extends the window where cash burn, dilution risk, and customer concentration matter more than TAM. The bigger second-order risk is that any slip in Neutron timing pushes investors to re-underwrite the stock as a specialty launcher rather than a platform compounder, which can cut another 20-30% off sentiment very quickly.

The contrarian angle is that the “expensive versus expensive” comparison is misleading: one name has a durable, cash-generative connectivity engine that can subsidize moonshots, while the other still needs product execution to prove the business model scales. That makes the right trade less about choosing between two hype vehicles and more about avoiding crowded long exposure to the weakest balance-sheet/earnings-quality profile. Over the next 3-6 months, the key catalyst is not revenue growth but launch reliability and any updated Neutron schedule; absent a clean milestone, the stock’s multiple is vulnerable to de-rating even if the broader space theme stays hot.

Key Decisions for Investors

• Avoid initiating new long RKLB exposure ahead of Neutron milestones; if already long, trim 25-50% on strength and reassess only after a confirmed schedule update. Risk/reward is poor while execution risk remains binary.
• Express a relative-value view with a long GOOGL / short RKLB pair over the next 1-3 months. The thesis is that AI infrastructure monetization has a clearer payback path than pre-profitability aerospace optionality.
• If you want upside exposure to the space theme, use small-sized call spreads on RKLB rather than stock, targeting post-catalyst volatility with defined downside. Structure around a 3-6 month horizon to avoid paying for open-ended execution risk.
• Watch for any Neutron delay or revised launch cadence as a sell signal for RKLB; use a break below recent support as a momentum exit trigger. That event would likely compress the multiple faster than fundamentals would deteriorate.
• Maintain only tactical exposure to NVDA/AI beneficiaries versus space hardware names; the article’s deeper signal is that AI-linked capex has a clearer monetization stack than launch-provider expansion. Favor names with near-term cash generation over long-duration storytelling.
