SPCX did not open at $135. It opened at $171.
Space Exploration Technologies Corp. began trading on Nasdaq Thursday morning roughly 27% above its IPO offer price — a gap that pushed the company's implied valuation toward $2.24 trillion on the first print. The stock had priced at $135 on Wednesday night after a $75 billion offering, already the largest IPO ever completed. The opening cross told a different story about demand.
Elon Musk, who once said SpaceX had less than a 10% chance of succeeding when he founded it, became the world's first trillionaire on paper as the stock cleared the opening bell.
What the Open Means
At $171, SPCX opened near the top of the range traders had flagged ahead of the debut. Desk chatter and order-book signals pointed to a first trade between $168 and $175 — roughly 25% to 30% above the offer. The actual print landed inside that band, confirming that institutional buyers who missed the allocation were willing to pay a steep premium in the secondary market.
The math is straightforward. SpaceX raised $75 billion at $135. Public shareholders who bought after the open paid $36 more per share for the same equity — before the first hour of trading added another layer of volatility.
Nasdaq marked the moment publicly. The exchange posted on X: "SpaceX listing day is here. Watch live. $SPCX." By mid-morning, SPCX was the most watched ticker on the platform.
Demand Before the Bell
The opening premium did not come from nowhere. Book-building data from the roadshow pointed to extraordinary appetite. Institutional accounts submitted more than $250 billion in orders against a $75 billion deal. Total demand across the syndicate reportedly approached $350 billion — a ratio that left most accounts with partial fills or none at all.
Float is limited. The offering was primary issuance with no insider selling at the offer price, which means the shares available for trading on day one represent a thin slice of SpaceX's total equity. When demand exceeds supply by that margin, the opening price becomes a clearing mechanism — not a reflection of where the stock will settle by the close.
Prediction markets picked up the same signal. On Kalshi, bettors priced in a near-term path for Musk's net worth toward $1.5 trillion this year — a figure that only works if SPCX holds or builds on the opening valuation.
Wall Street vs. the Floor
Not everyone expected $171 to be the ceiling. Peter Tuchman, the veteran NYSE floor trader known as "Einstein" for his long white hair, had floated a higher opening scenario in pre-market commentary. SPCX opened below that call — a reminder that even experienced traders misprice mega-IPOs when the book is this crowded.
Jim Cramer issued a separate caution on CNBC, warning retail investors about chasing an opening gap of this size. The debate between bulls and skeptics will run for weeks. The first print settled one question: demand exceeded even the bullish case at the offer price.
What Investors Are Actually Buying
SPCX is not a pure launch business anymore. The public equity wraps together several revenue lines that were previously accessible only to private-market investors:
- Starlink — subscriber growth and recurring broadband revenue across consumer, maritime, and aviation markets
- Launch services — Falcon 9 cadence and Starship development for commercial and government payloads
- Defense contracts — national security launch and satellite programs
- Starship optionality — Mars architecture, lunar lander contracts, and next-generation payload capacity
Index inclusion is the next catalyst. Passive funds tracking the Nasdaq-100 and broader U.S. equity indices cannot buy SPCX until eligibility rules are met — but once they can, the structural bid from ETF flows adds a layer of demand independent of day-one sentiment.
The First Session
Opening at $171 does not lock in a valuation. Mega-IPOs of this size typically see wide intraday ranges as arbitrage desks, IPO flippers, and long-only funds compete for position in the first hours.
What Thursday confirmed: the market priced SpaceX above $1.77 trillion before the bell even rang. At the open, it priced the company closer to $2.24 trillion. Whether that number holds through the close — and through the first week — is the trade that begins now.
