Could SpaceX Be Worth More Than Microsoft On Its IPO Day? Some Traders Are Betting On It

Prediction markets are pricing a wide range of debut valuations for SpaceX ahead of its expected IPO, including a 1% chance the company closes above $4 trillion and a 38% probability of exceeding $2.4 trillion. At the high end, that implies shares above $300, more than 125% above the expected $135 IPO price; at the low end, a sub-$1 trillion valuation would suggest about $76 per share. The article reflects euphoric but highly speculative sentiment around what could be the largest IPO in history.

Analysis

The market is not pricing SpaceX like a normal IPO; it is pricing a scarce, category-defining asset with embedded optionality on launch dominance, defense relevance, and satellite network monetization. That creates a reflexive first-day setup where the marginal buyer is less sensitive to fundamentals and more sensitive to relative status versus the mega-cap complex, which can produce a self-fulfilling overshoot in the opening print. The real second-order effect is on comparables: if SpaceX clears a wildly rich multiple, it temporarily raises the tolerance for “story premium” across private-growth and frontier infrastructure names.

The key risk is that prediction-market enthusiasm does not translate cleanly into actual demand once real inventory, lockup dynamics, and underwriting stabilization come into play. A first-day move above $300 would require sustained institutional sponsorship, not just retail momentum; absent that, the more likely path is a gap-up followed by a sharp mean reversion as valuation anchors reset. This is a days-to-weeks trade, not a months-long thesis, because post-IPO price discovery usually compresses when the float expands and early holders begin to monetize.

For MSFT and GOOGL, the direct impact is not earnings-relevant, but there is a sentiment channel: if SpaceX is treated as an elite public-market asset on day one, it can momentarily siphon attention from the existing Magnificent 7 cohort and distort factor flows toward long-duration growth beta. The contrarian view is that the market is underestimating how quickly novelty fades; if the company’s first-day trading is merely “very good” rather than spectacular, the implied odds embedded in speculative contracts can unwind fast. That makes the setup asymmetric for volatility sellers and opportunistic fade trades after the opening imbalance resolves.

Key Decisions for Investors

• Fade euphoric first-day strength via short-dated put spreads on the new listing after the opening range is established; target a 2-4 week window where mean reversion is most likely and avoid pre-open event risk.
• If listed liquidity is thin, use call credit spreads or ratio call spreads to monetize the probability that closing strength disappoints relative to prediction-market pricing; best risk/reward if implied vol prints extreme into the debut.
• Treat MSFT and GOOGL as relative losers in the attention trade only: consider a tactical pair of long a basket of non-mega-cap high-beta growth names versus short a small MSFT/GOOGL basket if the IPO drives a broad “new era” flow rotation over 1-3 sessions.
• For private-market exposure, reduce exposure to late-stage venture comp proxies that trade on scarcity premiums; the risk is a temporary repricing lower if SpaceX’s public multiple normalizes quickly after debut.
• If the stock opens above 2x IPO price, wait for the first liquidity event before committing capital; chase risk is poor versus a post-stabilization entry, where the forward risk/reward can improve by 30-50%.
