The IPO’s structure was unusual from the start. Rather than floating a price range and letting investor roadshows determine the final figure, SpaceX announced a fixed $135-per-share price weeks ahead of the debut, signaling extraordinary confidence in demand .

How a Tiny Float Created a Rocket Ship

The single most important number in the SpaceX IPO is not $85.7 billion—it is 4.9%. That is the percentage of total shares available to the public, even after the greenshoe exercise . At pricing, the float was just 4.2%, meaning that for a company valued at roughly $1.77 trillion at its IPO price, only a sliver of equity was actually trading .

A float this small creates extreme supply-demand friction, and the demand side was enormous:

• Retail orders exceeding $70 billion poured into the offering .
• Japanese retail investors alone submitted orders worth more than $6.2 billion (over 1 trillion yen), but were allocated only $2.2 billion—roughly 3% of the global offering . SpaceX had originally targeted $2 billion from Japanese buyers and later raised that goal to $2.5 billion after seeing overwhelming interest .
• U.S. retail brokerages including Robinhood, Charles Schwab, Fidelity, and SoFi managed to allocate at least one share to all qualifying customers who placed orders, underscoring how scarce the stock was .

The result? Shares that opened at $150 on June 12 kept climbing day after day. By June 16, SPCX was trading above $211.80, implying a market capitalization near $2.8 trillion . At its intraday peak on Tuesday, the market cap briefly touched $2.95 trillion—edging past Microsoft's own intraday record .

Surpassing Amazon and Joining the Top Five

By the morning of June 16, SpaceX had officially leapfrogged Amazon.com on the global market-cap leaderboard. Amazon’s market cap of roughly $2.65–$2.68 trillion was eclipsed by a company that had only been public for four trading days .

The trajectory was staggering:

• Day 1 (June 12): Opened at ~$150, closed at $160.95, market cap ~$2.1 trillion .
• Day 2 (June 15): Surged another 19%, lifting the market cap past Meta, Tesla, Broadcom, and on to roughly $2.5 trillion .
• Day 3 (June 16): Added another 10%+ in early trading to briefly surpass $2.9 trillion before settling near $2.8 trillion, firmly in fifth place globally .

Trading volumes reflected the frenzy. Over $1.16 billion in SPCX shares changed hands on Tuesday alone, and premarket volumes were described as multiple times larger than the next most-active stock on several platforms .

Analysts Call the Top—Forcefully

The market price tells one story; the fundamentals tell another. Within hours of SPCX’s first trade, Wall Street fired warning shots.

CFRA analyst Keith Snyder initiated coverage on June 12 with an unusual Sell rating and a $115 price target—well below the $135 IPO price and representing a decline of up to 46% from levels reached later that week . Snyder cited “an overly ambitious growth strategy, substantial capital intensity, and elevated valuation expectations” . His sum-of-the-parts analysis pegged the launch business at roughly $188 billion, Starlink near $700 billion, and other segments well short of the market’s implied valuation .

Morningstar analyst Nicolas Owens went even further, publishing a fair value estimate of just $63 per share ahead of the IPO . Morningstar characterized its own number as “the result of mathematics more than skepticism” and said the stock was deeply overvalued even before the post-IPO rally pushed it past $200.

A third firm, New Street Research, struck a more neutral tone with a $165 target price, but even that was well below where the shares traded by June 15 .

The bearish case centers on a simple mechanical risk: the same thin float that enabled the explosive rally could accelerate a collapse if sentiment turns. With so few shares available, a wave of selling could cascade just as quickly as the buying did .

Japan’s Unprecedented Retail Appetite

Perhaps no market reflected the SpaceX mania more vividly than Japan. The country’s household financial assets total roughly $15 trillion, and individual investors had seen few blockbuster IPOs since SoftBank Corp.’s 2018 debut .

• SpaceX initially planned to raise $2 billion from Japan, then increased the target by 25% to $2.5 billion .
• Final allocations came in at $2.2 billion, with 16.3 million Class A shares going to Japanese buyers—about 3% of the total offering .
• More than 1,000 individual Japanese customers each requested more than $624,500 worth of stock . Mizuho Securities USA handled the local portion of the deal .

The gap between demand and allocation—more than $6.2 billion sought versus $2.2 billion received—was one of the starkest illustrations of how much retail fervor outpaced available supply .

Additional Market and Regulatory Dynamics

• Index inclusion: SpaceX is widely expected to be fast-tracked into the Nasdaq 100, with additions to FTSE Russell and MSCI indexes anticipated soon thereafter, which would create structural passive buying pressure on the already scarce shares . Exact timelines were not confirmed in available sources.
• Financials: Post-merger with xAI, SpaceX reported roughly $18.67 billion in revenue and a $4.94 billion net loss, according to IPO filings cited in media coverage around the offering.
• Crypto spillover: The IPO triggered a parallel frenzy in digital assets, including tokenized SpaceX shares on decentralized exchanges, perpetual futures contracts themed around SPCX, and active prediction markets betting on the stock’s trajectory. A correlated Dogecoin rally gained momentum on Musk-related sentiment, though specific price and volume data were not captured in the source set.
• Geographic restrictions: Investors in mainland China and Hong Kong were explicitly barred from accessing IPO marketing materials and share allocations, as disclosed in the prospectus and attributed to regulatory and licensing constraints.

The Path Ahead: Momentum vs. Fundamentals

SpaceX’s public debut has been defined by a collision of forces that rarely converge at this scale: a transformative company with genuine technological assets, a founder who commands a global retail following, and a float so thin that price discovery has largely been driven by fear of missing out rather than calibrated valuation models.

The bull case rests on the same vision investors have backed for years—that SpaceX’s launch, Starlink, and AI businesses collectively justify a market cap larger than nearly every other company in the world. The bear case, articulated by CFRA and Morningstar, argues that current prices imply flawless execution on plans that remain deeply uncertain and capital-intensive.

For investors, the core question is whether the scarcity-driven rally represents a new plateau or a temporary distortion. As several analysts have warned, when the trade reverses, the float that made the ascent possible could make the descent far more dramatic .
