SpaceX Closing Market Cap End of IPO Month

Platform comparison

Market context

SpaceX is set to launch its Initial Public Offering on Nasdaq, with an anticipated pricing of $135 per share that would establish a market capitalisation of roughly $1.77 trillion. The prediction market in question resolves based on whether SpaceX’s closing market cap on the final trading day of its IPO month exceeds a specific threshold, though current crowd-implied probability for a “YES” outcome sits at just 1%, suggesting traders expect the valuation to fall short of that target despite the hype.

Historically, mega-IPOs in the tech and aerospace sectors have often seen initial euphoria followed by rapid consolidation; for instance, early trading days for companies like Tesla and Blue Origin showed volatile swings before settling into more grounded valuations. In SpaceX’s case, while Polymarket traders assign an 84% probability to the stock closing above $1.8 trillion and a 69% chance it exceeds $2 trillion on day one, analyst consensus from Morningstar values the firm at only $780 billion, highlighting a stark divergence between speculative optimism and fundamental assessment. This gap mirrors patterns seen in prior high-profile IPOs where market sentiment outpaced intrinsic value in the short term.

Traders should monitor key catalysts including the official opening price, pre-market trading volume, and any regulatory updates affecting SpaceX’s inclusion in the Nasdaq 100 Index, which is expected within 15 trading days post-IPO. Recent reports from CNBC note that pre-IPO perpetual futures on Hyperliquid suggest a potential 20% surge on the first trading session, while TradingKey data indicates an 83% probability of the stock opening between $150 and $200. However, with valuation lock-ups and early excitement potentially waning by July and August, momentum may only pick up again by September 2026, as projected by CoinCodex. The settlement window ends 1 July 2026, meaning the final closing price of June will determine the outcome.
