SpaceX Could Be the Biggest IPO in History. Here's What Happened to the Last 5 Mega-IPOs.

SpaceX is reportedly targeting a valuation above $2 trillion and a roughly $75 billion raise, which would make it the largest IPO in history and imply a 108x price-to-sales multiple on $18.5 billion of revenue. The article argues that the company’s launch dominance and Starlink revenue are outweighed by the extreme valuation, especially given that most mega-IPOs have underperformed the market long term. The piece concludes investors should avoid buying at IPO and wait for a potential post-listing pullback.

Analysis

This is less a public-market opportunity than a price-discovery event for private-market appetite. At a 100x+ sales entry point, the stock would need years of flawless execution just to earn the right to be considered “normal,” and that creates a brutal setup for post-listing de-rating even if the business remains excellent. The more important implication is that a SpaceX IPO would likely reset underwriting standards across late-stage growth: if a category-defining asset clears at this multiple, every other frontier-tech issuer will try to re-anchor its own expectations higher.

The secondary winners are likely not the obvious aerospace names but the adjacent picks-and-shovels beneficiaries: launch suppliers, satellite components, data infrastructure, and insurance/financing intermediaries that can benefit from broader capital formation without having to justify the same valuation bar. The losers are any near-private rivals that were hoping to raise at aggressive terms; a weak post-IPO trade would quickly compress private comparables and make crossover funds more disciplined on future rounds.

The key risk is timing. IPO hype can overwhelm fundamentals for weeks or months, but by 6-12 months the market usually re-prices toward growth durability and margin visibility, not narrative dominance. The real catalyst that could offset the valuation overhang is a visible acceleration in Starlink monetization and operating leverage; absent that, the stock will likely trade as a “great company, bad stock” with a narrow path to upside from the offering price.

Contrarian take: the market may be underestimating the scarcity value of a profitable, globally scaled space platform with both consumer and enterprise revenue. That said, scarcity does not immunize against multiple compression, and the first trade after listing is often driven by benchmark demand and index inclusion mechanics rather than rational long-term ownership. The better setup is probably not chasing the IPO, but waiting for forced selling or a post-lockup dislocation to establish exposure if growth inflects.

Key Decisions for Investors

• Avoid participating in the IPO at offer; wait 3-6 months post-listing for the first real fundamentals-driven reset, when lockup supply and analyst model revisions can create a 20-35% better entry.
• If listed, consider a short-dated post-IPO put spread on SpaceX for the first 1-2 quarters of trading to express mean reversion risk; the trade works if the market shifts from scarcity premium to valuation discipline.
• Overweight NVDA only as a comparison anchor for what true hyper-growth can justify; use SpaceX’s tape as a read-through on whether the market is again willing to pay 30-40x sales for secular growth, but do not extrapolate that multiple blindly into other names.
• For public-market expression of the theme, buy a basket of aerospace/satellite infrastructure suppliers on any IPO enthusiasm-driven pullback; these names can capture second-order capex flow without the same valuation risk.
• If SpaceX weakens materially after lockup expiration, initiate a staged long on a 6-12 month horizon only if Starlink revenue re-acceleration is visible; otherwise treat it as a trading vehicle, not a core position.
