SpaceX's recent confidential S-1 IPO filing, targeting a June listing at over $2 trillion valuation, has sharpened trader focus on its public ticker, with market-implied odds split closely at 48.5% for $X versus 45% for Other. The edge for $X stems from Elon Musk's longstanding "X" branding—seen in X Corp (formerly Twitter) and xAI—fueling speculation of a single-letter symbol to unify his ecosystem amid Starship milestones and Starlink expansion. However, Other gains traction due to single-letter ticker scarcity, regulatory hurdles, and premium costs, as Nasdaq prioritizes availability; low-volume options like $SPAX or $SEX reflect memes over substance. Key swing factors include roadshow disclosures and SEC feedback, with resolution nearing as filing details emerge.

An official announcement from SpaceX that they will IPO under a specific ticker symbol will be sufficient to resolve this market.
If a ticker used by SpaceX in a qualifying IPO is a variant of a ticker symbol listed in this market group with additional letters to denote a specific class of shares, it will be considered to be that ticker (e.g. if SpaceX uses a ticker symbol of $MARS.A or $MARSA, this market will resolve to $MARS).
If SpaceX announces an IPO with multiple tickers that are not considered the same ticker under the previous rule (i.e. $MARS.A and $MARS.B would be considered the same ticker), this market will remain open until SpaceX’s first day of public trading and will resolve according to the ticker symbolizing the security class with the greatest market capitalization. Market capitalization is calculated as the number of shares outstanding multiplied by the closing share price on the first trading day. If this also results in a tie, this market will resolve according to the ticker symbol that comes first in alphabetical order.
If SpaceX IPOs with a non-listed ticker, or does not IPO or officially announce an IPO and ticker symbol by December 31, 2027, 11:59 PM ET, this market will resolve to “Other.”
The primary resolution source for this market will be official information from SpaceX and the primary exchange’s official listing page. In the event that the relevant figure is not displayed, another reliable source will be used.
Note: 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 use the official closing price of the abbreviated session. If no such official closing price is published, the market will use the closing price on the next trading day for which an official closing price is published, treating that as the first day of trading for purposes of this market.
