SpaceX IPO Could Crown It a $2 Trillion Company, Prediction Markets Signal

Benzinga reported Wednesday that prediction market platform Polymarket has placed a 75% probability on SpaceX reaching a $2 trillion market cap following its imminent public debut. The SpaceX IPO is now expected within weeks, according to the outlet.

Polymarket Odds Paint a Bullish Picture

Bettors on Polymarket are overwhelmingly optimistic about the commercial space company’s opening valuation. The platform currently shows an 89% chance the market cap clears $1.8 trillion post-listing. Confidence only grows lower down the scale. Traders assign 99% probability the company tops $1 trillion, with 98%, 96%, and 95% odds attached to thresholds of $1.2 trillion, $1.4 trillion, and $1.6 trillion respectively. The implied floor sits well above most large-cap technology peers at the time of listing.

SpaceX Filing and Pricing Details

Elon Musk‘s SpaceX has already submitted an amended S-1 registration document with the Securities and Exchange Commission, Benzinga noted. That filing disclosed the company may issue substantial new equity to support future acquisitions or mergers. On the pricing front, SpaceX is reportedly targeting the sale of roughly 555.6 million shares at $135 per share. That figure would be set before the formal IPO roadshow kicks off.

The Tesla Merger Speculation

No SpaceX IPO conversation is complete without addressing the Tesla angle. Wedbush Securities analyst Dan Ives has suggested a potential merger between SpaceX and Tesla Inc. could materialise as early as 2027. Any such combination carries significant implications for Musk’s compensation. Under the terms of his existing $1 trillion Tesla pay package, a merger or acquisition could void the milestone conditions tied to that award. Should a deal close, Musk’s payout would then hinge purely on the combined company’s market capitalisation.

Background: SpaceX’s Path to Public Markets

SpaceX has long been among the most closely watched private companies in the world. The firm secured a valuation of around $350 billion in a secondary share sale in late 2024, making Wednesday’s $2 trillion projection a near sixfold increase in roughly 18 months. Its Starship heavy-lift rocket programme and Starlink satellite internet division are the primary growth narratives underpinning investor enthusiasm heading into the listing.
