SpaceX’s anticipated public debut has triggered a wave of speculation across prediction markets and social media, with traders wagering over $15.2 million on its future ticker symbol, listing exchange, and valuation.

On Polymarket, the odds of SpaceX adopting the single-letter ticker “X” have plummeted to 25% from 60% a month ago. The symbol became available after U.S. Steel’s delisting last year. Elon Musk’s social platform, also named X, adds intrigue-but alternatives like “SPCX,” “SPAX,” and even “SEX” are circulating.

Tuttle Capital Management CEO Matthew Tuttle, whose firm uses SPCX for an ETF, said he’d consider selling the ticker: “My phone line is still open.”

The company aims for a $1.75 trillion market cap at listing-enough to vault it past Tesla and Meta, potentially reshaping Wall Street’s elite “Magnificent Seven” into a “Super Eight.”

Retail enthusiasm is surging. SpaceX ranked as the 19th most-mentioned stock on Reddit’s r/WallStreetBets last week. Sources tell Reuters Elon Musk may reserve up to 30% of the IPO for individual investors-triple the typical allocation.

“Most people would say yes to investing in Elon Musk’s space company,” said Meridian Equity Partners’ Jonathan Corpina.
