SpaceX IPO Closing Market Cap (Lowest Strikes)

What you need to know

This market is asking: if SpaceX goes public before 2028, how much will the whole company be worth on its very first day of trading? The options shown here are the lowest end of the range — under $600 billion, or no IPO at all before 2028 — and the market is currently saying those outcomes are essentially off the table. The $1 trillion-plus outcome, shown at 99%, reflects strong collective belief that if SpaceX does go public, it will debut as one of the most valuable companies ever listed. This market settles based on SpaceX's total market cap at the official closing price on its first trading day — calculated by multiplying all shares by that closing price. If there is no IPO by December 31, 2027 at 11:59 PM ET, it resolves to 'No IPO before 2028.' One edge case worth knowing: if trading is interrupted on day one (say, a circuit breaker halts the session), the market uses the next day an official closing price is published instead. A June 2026 news piece focused on the community growing around SpaceX's Starbase launch site in Texas — covering both the economic boom and social tensions the company's presence has brought. This is background color about SpaceX's expanding footprint, but it doesn't directly signal whether or when an IPO might happen or at what valuation. The near-total weight on the $1 trillion-plus outcome means the main open question isn't really about valuation — it's whether an IPO happens at all before 2028. SpaceX is privately held and Elon Musk has historically shown no urgency to list the company publicly. The timeline is genuinely unpredictable: a decision to go public could come quickly or not at all within this window. If an IPO does happen, SpaceX's private-market valuations have already exceeded $350 billion, which is why the market sees a $1 trillion-plus debut as far more plausible than a lower figure.

Price history

How this resolves

Resolves December 31, 2027

This market will resolve based on SpaceX's market capitalization at the closing price on its first day of trading. If no SpaceX IPO occurs by December 31, 2027, 11:59 PM ET, the market will resolve to "No IPO before 2028". Market capitalization expresses the monetary value of a company’s outstanding shares, stated in its pricing currency. It is calculated as the number of shares outstanding multiplied by the closing share price on the first trading day. If the relevant value falls exactly between two brackets, then this market will resolve to the higher range bracket. Resolution will be based on the primary exchange’s official listing page. In the event that the relevant figure is not displayed, another reliable source will be used. In the event of an interruption in the course of the normal trading session on SpaceX’s first day of trading (e.g., a circuit breaker or half-day), the market will resolve according to the official closing price of the abbreviated session. If no such official closing price is published, the market will resolve according to the next trading day on which an official closing price is published, treating that as the first day of trading for purposes of this market.
