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.Trader consensus on Polymarket heavily favors a SpaceX IPO closing market cap between $1.5 trillion and $2.5 trillion (74.5% implied probability across top outcomes), driven by the company's confidential S-1 filing in early April 2026 and subsequent prospectus details targeting $1.75 trillion initially, later raised above $2 trillion amid surging secondary market trades at $1.48 trillion. Starlink's $4.4 billion 2025 operating income funds aggressive $20 billion AI capex, bolstered by an xAI merger and Musk's dual-class shares ensuring post-IPO control, while ambitious space-based AI data centers and Mars incentives fuel hype. Recent tender offers doubled valuation from $800 billion in late 2025, but high multiples (100x+ revenue) reflect narrative bets on Starship dominance. Early June roadshow looms as the key catalyst, with risks from unproven tech timelines.
