SpaceX, the aerospace and satellite company founded by Elon Musk in 2002, has long been speculated as a potential initial public offering candidate. An IPO would represent a significant transition from private operations to public markets, with the opening-day market cap reflecting investor valuation at close. This market predicts whether SpaceX's market capitalization will specifically fall between $2.0 trillion and $2.5 trillion at the close of its IPO trading day. A valuation in this range would position SpaceX among the highest-valued US companies, reflecting investor confidence in its rocket launch capabilities, Starlink satellite internet, and space infrastructure assets. The 22% odds on YES suggest market participants currently view this mid-range outcome as less probable than valuations either below $2.0T or above $2.5T. Factors influencing the final IPO price include SpaceX's profitability trajectory, competitive positioning in space services, regulatory environment, and broader market conditions at the time of listing. The market resolves using the official market capitalization at market close on IPO day, calculated from the closing price times fully diluted shares outstanding.
