Forget SpaceX Stock -- Is RocketLab the Better Buy?

SpaceX is reportedly targeting a June IPO with a $1.75 trillion valuation and plans to allocate up to 30% of shares to retail investors, but the article argues that the stock may launch near peak valuation. Revenue growth is said to have slowed to 18% in 2025 from 51% in 2024 and 89% in 2023, while a $250 billion xAI stock deal and an estimated $5 billion loss in 2025 add risk. Rocket Lab is presented as the lower-risk public alternative, with a $49 billion market cap and upcoming Neutron rocket launch, though its 74 P/S multiple leaves limited margin for error.

Analysis

The market is likely underestimating how much a richly priced SpaceX IPO could re-rate the entire private-space complex rather than just the issuer itself. A headline-grabbing float at a lofty valuation would probably compress the relative scarcity premium that has supported venture marks, while simultaneously forcing public-market investors to benchmark the sector against revenue maturity, not narrative optionality. That matters because the next marginal dollar in space is likely to favor the names with visible launch cadence and credible capital discipline, not the one with the most brand heat.

Rocket Lab is the cleaner beneficiary only if execution stays ahead of expectations. Its real upside is not simply being the “public SpaceX proxy,” but becoming the default liquidity outlet for investors who want orbital exposure without the governance and valuation overhang of a mega-cap debut. The problem is that a high-multiple leader-board trade can be fragile: any delay in Neutron or slip in launch cadence would hit the stock first through multiple compression, then through estimates, which is why the risk window is measured in months around product milestones rather than years.

The more interesting second-order effect is on adjacent beneficiaries that are not named in the article: launch suppliers, avionics, thermal management, and test infrastructure vendors could see a modest halo regardless of which rocket company wins. If retail allocation is unusually high, expect a short-lived momentum phase that can detach pricing from fundamentals for 1-3 months post-IPO, but that same retail mix also creates a sharper drawdown risk once lock-up chatter and execution scrutiny begin. In other words, the initial trade is sentiment-driven; the durable trade will be supply-chain enablement and recurring service contracts.

Consensus seems to think the choice is “SpaceX expensive vs. Rocket Lab cheaper.” The more important distinction is that both names are still priced as option-like claims on an industry with a long commercialization runway, so the best risk/reward may be expressed through relative value and catalysts rather than outright beta. If the IPO goes well, Rocket Lab likely catches the first spillover bid; if it disappoints or arrives at a weak tape, the public space basket could de-rate together, making patience on entry more attractive than chasing pre-event enthusiasm.

Key Decisions for Investors

• Wait for the SpaceX IPO pricing range before taking directional risk; if it prices at the top end and trades above 20x forward revenue-equivalent metrics, fade initial momentum via a short-dated put spread rather than short stock, targeting a 4-6 week post-listing mean reversion.
• Maintain a tactical long RKLB only on post-launch confirmation in Neutron execution; use a staggered entry into catalyst windows over the next 1-2 quarters, with a hard stop on any schedule slip that breaks the launch cadence narrative.
• Run a pair trade: long RKLB / short a broad high-multiple growth basket, or short a space-IPO hype proxy if available, to isolate sector enthusiasm from general risk-on beta; this is best held for 1-3 months around the IPO event.
• For lower-volatility exposure, look at suppliers to launch infrastructure and components on pullbacks, as these names may benefit from sector capital formation even if the headline IPO trades poorly; prefer businesses with recurring contract revenue over one-off launch economics.
• Do not chase the first post-IPO rally in SpaceX unless retail participation is clearly fading; if the stock goes parabolic in the first 2-3 sessions, use call spreads instead of outright equity to cap drawdown risk from a meme-style reversal.
