The Day History Was Made

When the opening bell rang at the Nasdaq on June 12, 2026, audible cheers broke out from the crowd gathered outside in Times Square. Space Exploration Technologies Corp. — trading under the ticker SPCX — had finally arrived on public markets after 24 years as a private company, and it wasted no time rewriting the record books.

Shares opened at $150, representing an 11% premium to the $135 IPO price, before running to an intraday high of $176.52 and closing the session at $161.11 — a 19% gain that added over $300 billion to the company’s market capitalisation in a single trading day (CNBC, June 12, 2026). Class A volume topped 207 million shares, with dollar volume surpassing $33 billion — dwarfing the combined turnover of QQQ and SPY ETFs on the same session (CNBC Live Updates).

By Monday, shares extended their gains to $192.50, pushing SpaceX’s market capitalisation toward $2.6 trillion and leapfrogging Amazon to become the sixth-largest U.S. company by value (Intellectia AI). As of June 22, SPCX trades at approximately $185, with a 52-week range of $135–$225.64 (Investing.com).

The Numbers Behind the Hype

SpaceX’s prospectus revealed a company of extraordinary contradictions. On one hand, the revenue trajectory is genuinely impressive: the company recorded $18.7 billion in revenue in 2025, up 33% year-on-year, driven almost entirely by Starlink, which now counts more than 10 million subscribers across 160 countries and contributes approximately 60% of total revenues (Prof G Media, May 2026).

On the other hand, the bottom line tells a more complicated story. Despite Starlink generating $1.2 billion in operating income in a single quarter at a 36% margin, the company swung from a $791 million net profit in 2024 to a $4.94 billion net loss in 2025 (Prof G Media). The culprit: an aggressive $21 billion capital expenditure programme, of which $12.7 billion was directed toward building out data centres for xAI — more than the company spent on rockets or satellites combined.

The offering structure itself was historic. SpaceX raised $85.7 billion selling over 555 million Class A shares, with underwriters exercising their full greenshoe overallotment option — a mechanism SpaceX employees celebrated by literally wearing green shoes on the trading floor (Fortune, June 12, 2026). The deal was led by a 21-bank syndicate with Goldman Sachs as lead-left bookrunner, having drawn $250 billion in orders during the roadshow (Fortune).

The Valuation Debate: $63 or $310?

No question is generating more debate on Wall Street than what SPCX is actually worth. The analyst community is extraordinarily divided, with price targets spanning from $62 (Morningstar) to $401 (Arete Research) — a range that reflects genuine uncertainty about how to value a company simultaneously running established profitable businesses and pursuing transformative but entirely unproven technologies (The VC Corner; Yahoo Finance).

The bull case, articulated by Goldman Sachs and ARK Invest, positions SpaceX as a generational investment comparable to early-stage Amazon or Apple. Analysts project revenue of $25 billion for 2026, with Elon Musk himself suggesting the company could reach $1 trillion in annual revenue by 2030 (Intellectia AI). The orbital AI data centre thesis — wherein SpaceX leverages its unique launch capacity to host compute infrastructure in low-earth orbit, bypassing terrestrial power and cooling constraints — represents the kind of platform optionality that public markets have historically rewarded with premium multiples.

The bear case is equally compelling. At its current price, SPCX trades at approximately 115 times trailing twelve-month sales — far exceeding even Palantir Technologies, the S&P 500’s richest-valued constituent at 59 times sales (Yahoo Finance, June 2026). Historical precedent is discouraging for buyers at these levels: among the 15 largest U.S. IPOs since 2006, the average stock declined 50% at some point during its first year and finished 33% below its IPO price after twelve months (Yahoo Finance / Motley Fool analysis).

One structural factor the bears may be underweighting: MSCI’s early-inclusion methodology kicked in on June 13, one day after listing. At its post-debut valuation, SpaceX became one of the 10 largest constituents of the MSCI World and MSCI ACWI indices, triggering an estimated $15–20 trillion of passive funds needing to buy SPCX — with only a 4% float currently available (The VC Corner). That structural demand imbalance is a near-term price floor the valuation models are not capturing.

Governance Concerns: One Man’s Rocket

Any serious analysis of SPCX must reckon with its governance structure. Elon Musk serves simultaneously as CEO, CTO, and Chairman of the Board, holding 85% of total voting power — meaning he effectively cannot be removed without his own consent (Prof G Media). Public investors purchasing Class A shares are, in practical terms, providing capital for a vision they have no ability to meaningfully influence.

The S-1 itself is a document unlike any in recent IPO history. Its first 14 pages consist entirely of photographs of rockets. A direct quote from the filing: “We do not want humans to have the same fate as dinosaurs.” The document positions SpaceX not as a company seeking a return on capital but as a civilisational project that happens to have a balance sheet (Prof G Media).

There is also the unresolved Starship question. SpaceX’s most ambitious growth projections rest on the commercial viability of Starship — a vehicle that remains grounded while the FAA conducts a mishap investigation into its most recent test flight (Fortune). The timeline for FAA clearance is uncertain, and any further delay compresses the window for the launch economics that underpin the orbital data centre thesis.

What It Means for Capital Markets

SpaceX’s debut is not just a company story. It marks the opening act of what Bloomberg and Fortune are calling “IPO Summer 2026.” Anthropic confidentially filed its S-1 on June 1, followed by OpenAI on June 8, with the latter targeting a September debut at an $852 billion valuation (Fortune). SpaceX, Anthropic, and OpenAI together could demand north of $200 billion from public markets in a single calendar year — against a backdrop where the entire U.S. IPO market raised just $45 billion in all of 2025 (IndMoney, June 2026).

For institutional investors, the displacement risk is real. Money rotating into SPCX has to come from somewhere, and that somewhere is likely existing Magnificent 7 positions. Even investors who never touch an IPO stock may feel this as a headwind in portfolios they already hold.

SpaceX also received investment-grade credit ratings from all three major agencies — Moody’s, Fitch, and S&P Global — on June 18, strengthening its standing in debt markets and opening the door to lower-cost financing for its capital-intensive expansion plans (Investing.com).

The Bottom Line

SpaceX is, by almost any measure, a genuinely remarkable company. Its achievements in reusable rocketry and satellite internet are revolutionary, and Starlink’s unit economics — 36% operating margins, 10 million subscribers, no serious competitor — would justify a premium valuation on their own. The question is not whether SpaceX deserves to be a large, valuable public company. It almost certainly does.

The question is whether it deserves to be a $2.5 trillion public company today, pricing in flawless execution across Starship commercialisation, orbital AI infrastructure, and xAI integration simultaneously, with a governance structure that concentrates all decision-making in a single individual and a float so thin that price discovery remains structurally impaired.

For investors with a long time horizon and a high tolerance for volatility, SPCX offers direct exposure to the commercialisation of space — a genuinely novel asset class that no other publicly traded vehicle provides. For those expecting near-term returns to match opening-day enthusiasm, history offers a cautionary note.

SpaceX’s blockbuster stock market debut earlier this month has continued to reverberate through global markets, cementing Elon Musk’s status as the world’s first trillionaire and reshaping the landscape of the world’s most valuable public companies.

A Historic Debut

SpaceX shares, trading under the ticker “SPCX” on the Nasdaq, opened at $150 — above their $135 IPO price — and surged as high as $176.52 before closing the first day up roughly 19% at $160.95, according to CNN Business. The offering raised approximately $75 billion, making it the largest IPO in history, NPR reported, and valued the rocket and satellite company at more than $2 trillion in early trading.

CNBC reported that shares continued climbing in after-hours trading, pushing the company’s market capitalization to roughly $2.2 trillion and briefly making SpaceX the sixth-largest publicly traded company in the United States, ahead of Musk’s other company, Tesla.

Musk’s Stake and Control

Musk’s roughly 40% ownership stake in SpaceX has been valued at around $800 billion in the wake of the listing, NPR reported, a figure that — combined with his Tesla holdings and other assets — pushed his total net worth past the trillion-dollar threshold for the first time for any individual. Notably, Musk retains more than 80% of SpaceX’s voting power, according to NPR, meaning public shareholders will have limited influence over how the company is run despite the broad-based retail demand for shares.

Why Investors Bought In

According to CNBC, Musk said on a livestream ahead of the offering that SpaceX has been cash-flow positive since around 2015 and that the IPO was intended to fund a major growth phase, including plans to deploy over 100,000 satellites and build AI data centers in space. The company’s only currently profitable division is its Starlink satellite internet business, which CNBC noted generated the majority of SpaceX’s $18.67 billion in revenue last year.

Despite the bullish reception, NPR reported that SpaceX’s financial filings show the company lost roughly $5 billion last year and another $4 billion in the first quarter of 2026, with much of that loss tied to the AI division absorbed from Musk’s former company, xAI, which SpaceX acquired in early 2026.

A Hidden Winner: Alphabet

Among the lesser-discussed beneficiaries of the listing is Alphabet, which CNBC reported owns roughly 4.9% of SpaceX — a stake now worth an estimated $105 billion, making it one of Google’s most lucrative private investments ever.

What Comes Next

CNN Business noted that SpaceX’s amended IPO filing flagged the possibility of issuing “significant equity” to fund future transactions, fueling market speculation about a potential future tie-up with Tesla, in which SpaceX already holds a stake stemming from Tesla’s earlier $2 billion investment in xAI.
