SpaceX’s anticipated public debut generates massive excitement on Wall Street, fueled by viral rocket launches and intense social media speculation. Traders wager heavily on the company’s ticker symbol, listing exchange, and valuation, even before any IPO filing.
Prediction Markets Heat Up Over Ticker Choices
On Polymarket, betting volumes for SpaceX-related outcomes surpass US$15.2 million as of Friday. Prediction markets show a 25% probability for the single-letter ticker “X,” down sharply from 60% a month earlier. The symbol became available after U.S. Steel delisted from the New York Stock Exchange following its acquisition by Japan’s Nippon Steel. Elon Musk’s social media platform, rebranded as X in 2023, adds to the intrigue.
Matthew Tuttle, CEO of Tuttle Capital Management, proposes “SPCX”—currently the ticker for an ETF his firm manages—and expresses willingness to sell it. “I’ve not heard from Elon, but my phone line is still open and I’m holding out hope that I get a call,” Tuttle stated. Other Polymarket options include “SPAX” and “SEX,” though bettors assign a 70% chance to an entirely different ticker.
Record Valuation Eyes Top U.S. Spot
SpaceX aims for a US$1.75-trillion valuation in its listing, positioning it as the sixth-largest U.S. company by market cap. This would surpass Tesla’s US$1.4-trillion and Meta Platforms’ US$1.39-trillion valuations, prompting debates over the “Magnificent Seven” tech giants.
“When the company does finally go public, the Magnificent Seven will clearly expand. They’ll probably call it the Magnificent Eight, the Super Eight or some new acronym,” said Todd Schoenberger, chief investment officer at CrossCheck Management.
Retail Investors in the Spotlight
CEO Elon Musk considers reserving up to 30% of the IPO shares for individual investors—triple the typical allocation—to leverage his strong retail following. Data from Breakout Point reveals SpaceX mentioned 130 times on Reddit’s r/WallStreetBets over the past week, ranking 19th in popularity.
“The retail investor plays a very significant role when you have a company like SpaceX that’s coming public. Most people would say yes to the opportunity of investing in Elon Musk’s space company,” noted Jonathan Corpina, senior managing partner at Meridian Equity Partners.
