Elon Musk’s SpaceX is set to launch the biggest stock market float in history amid warnings that it may be overvalued.
The space exploration, satellite broadband and AI company will join the US stock market on Friday at a valuation of $1.78tn, after offering at least $75bn of shares to investors through an initial public offering.
The offering is oversubscribed by three or four times, according to Reuters, with more than $250bn of bids from investors keen to take part in the IPO.
The $75bn share offer is nearly three times the previous record, Saudi Aramco’s $29.4bn offer when it floated in 2019. If the float goes as planned, Musk could make history as the world’s first trillionaire.
However, the investment research group Morningstar has calculated that SpaceX is worth only $63 a share – well below the anticipated IPO price of $135 – and warns there is “a major disconnect between market expectations and underlying fundamentals”.
Michael Field, the chief equity strategist at Morningstar, suggests investors should sit out the IPO and wait for “a more attractive entry point down the line”.
“We believe the business has real strengths, particularly in Starlink, but with so many unknown and untested technologies underpinning much of the valuation price, particularly within the AI business, we think the valuation is extremely speculative,” Field said.
SpaceX, which made a net loss of $4.9bn in 2025, is made up of three businesses: space exploration, including its Falcon and Starship rockets; connectivity, such as its Starlink satellite constellation providing high-speed internet access; and artificial intelligence, though its xAI division.
At $1.78tn, the IPO values SpaceX at roughly 92 times its trailing sales, a very hefty valuation which means investors are wagering that Musk can achieve his ambitious goals for the company – such as orbital datacentres in space, building a base on the moon and cities on other planets, and to “extend the light of consciousness to the stars”.
SpaceX has claimed that Starlink has a total addressable market of $1.6tn; Morningstar estimates the segment’s realistic global opportunity at about $129bn.
Earlier this week, the US senator Elizabeth Warren called for the Securities and Exchange Commission to delay SpaceX’s IPO, owing to concerns about the company’s valuation and corporate governance.
“Given the unprecedented threats to investor protection and market integrity posed by the biggest IPO in history, you must delay any eventual acceleration of the registration statement’s effectiveness accordingly,” Warren wrote to the market regulator on Tuesday.
Investors who do not take part in the IPO may still find themselves with a stake in SpaceX, once the company is added to stock market indices.
Earlier this week the index provider MSCI confirmed it would apply existing rules for early inclusion of large IPOs in its Global Standard Indexes, which probably clears the way for SpaceX to join. That would create demand from passively managed investment funds which track those indices.
The Nasdaq index has made changes that will make it easier for new listings such as SpaceX to join its indices.
However, S&P Dow Jones Indices has declined to relax its strict entry rules, blocking fast-track inclusion, which means it could take months before SpaceX is added to the tech-heavy S&P 500 stock index.
Four leading AI models discuss this article
"The IPO price is built on speculative growth in Starlink and xAI, making the valuation highly sensitive to execution, capital spend, and macro/regulatory shifts; a miss on monetization could trigger a sharp re-rating."
SpaceX's IPO is a high-stakes test of growth-at-any-cost logic. While the company touts Starlink and xAI, the valuation discounts a path to profitability that remains unproven and depends on uncertain catalysts. The article's note of Morningstar's $63/share vs $135 IPO price underscores big sensitivity to execution risk, capex burn, and external factors like rate moves and regulatory changes. Add in potential supply on day one, index inclusion dynamics, and governance concerns raised by lawmakers. The strongest concern: the price may not be sustainable if growth misses, and risk-reward could skew to a large downside.
Against my stance, a few quarters of rapid Starlink monetization and breakthroughs in xAI might justify a higher multiple, and index inflows could sustain premium valuations.
"The IPO’s 92x sales multiple relies on speculative AI and space-based revenue that ignores the reality of massive capital expenditure requirements and intense regulatory scrutiny."
A $1.78 trillion valuation on a company with a $4.9 billion net loss is not an investment; it is a venture capital bet masquerading as a public equity offering. Trading at 92x trailing sales, SpaceX is priced for perfection across three distinct, high-risk verticals: launch, connectivity, and AI. While Starlink’s growth is impressive, the delta between the company’s $1.6 trillion TAM estimate and Morningstar’s $129 billion projection highlights a massive disconnect. Passive index inclusion via MSCI will force institutional buying, creating a temporary liquidity floor, but the fundamental lack of earnings visibility makes this a dangerous play for retail investors until the cash burn stabilizes.
If Starship achieves full reusability, launch costs will collapse, potentially granting SpaceX a global monopoly on orbital infrastructure that makes current revenue multiples look conservative.
"SpaceX's $1.78tn valuation is disconnected from near-term cash generation, but forced index inclusion will likely support the stock price for 12-18 months regardless, creating a structural bid that has nothing to do with fundamentals."
SpaceX at $1.78tn is a valuation event masquerading as a fundamental story. The 92x sales multiple and $4.9bn net loss in 2025 are real red flags, but the article buries the actual risk: forced passive inclusion via MSCI creates a bid floor independent of fundamentals. That $250bn+ in IPO demand isn't rational exuberance—it's index-tracking money that will chase this into indices regardless of Morningstar's $63 fair value. The real question isn't whether SpaceX is overvalued (it likely is), but whether index inclusion mechanics override valuation discipline for 12-24 months. Starlink's $129bn TAM vs. $1.6tn claim is the only credible cash-generation anchor; everything else is optionality priced as certainty.
If Starlink reaches even 20% penetration of that $129bn TAM within five years at 70% gross margins, the cash flow justifies a $400-600bn valuation for that segment alone—and Falcon/Starship have genuine monopoly economics in launch that the market hasn't fully priced. The article conflates valuation skepticism with business skepticism.
"SpaceX's valuation embeds execution on multiple untested technologies that Morningstar correctly flags as speculative, making a post-IPO drawdown likely once initial hype fades."
The $1.78tn IPO price at 92x trailing sales looks detached from SpaceX's $4.9bn 2025 net loss and Morningstar's $63 fair-value estimate. Starlink's realistic TAM of $129bn versus the claimed $1.6tn, plus unproven AI and orbital data-center bets, points to a steep re-rating risk once lockups expire. Index inclusion via MSCI and Nasdaq may create mechanical buying, yet S&P's refusal to fast-track delays passive inflows and leaves room for fundamental sellers. Warren's SEC letter adds governance overhang that could extend the quiet period.
Oversubscription of 3-4x with $250bn in bids suggests institutional conviction that can sustain the valuation for 6-12 months regardless of near-term earnings, turning the IPO into a momentum trade rather than a fundamentals bet.
"Index flows can create a bid floor, but they won't immunize SpaceX from a fundamental re-rating once profitability remains unproven."
Claude is right about potential bid floors, but that ignores the durability risk once flows ebb. Even with index buying, SpaceX must prove a credible path to profitability; 4.9bn net loss and discretionary capex mean a re-rating could hit quickly on misses or higher discount rates. The public market also adds quarterly-pressures on Starlink monetization and platform bets (Falcon/Starship), risking misaligned incentives relative to long-horizon value.
"The reliance on index inclusion overlooks the catastrophic risk of governance and key-man volatility inherent in SpaceX's leadership structure."
Claude and Grok focus on index mechanics, but they ignore the 'key-man' risk profile. SpaceX is uniquely tethered to Elon Musk’s public volatility. Unlike a standard tech IPO, SpaceX’s governance is a binary risk factor; if Musk’s political or external business entanglements trigger SEC scrutiny or defense contract reviews, the institutional bid floor will evaporate regardless of MSCI inclusion. The valuation isn't just a multiple of sales; it is a leveraged bet on Musk’s continued operational control.
"Musk volatility is a known risk; regulatory fragmentation of Starlink's TAM is the hidden valuation cliff."
Gemini's key-man risk is real but overstated as a valuation driver. SpaceX's defense contracts ($2.1bn FY2024) are already scrutinized; additional SEC/DoD review wouldn't be a surprise—it's priced into the risk. The actual durability question: can Starlink hit $129bn TAM at 70% margins without regulatory fragmentation (EU licensing, India spectrum auctions)? That's the earnings visibility gap nobody's quantified. Index inclusion buys 12-18 months; regulatory fracture buys nothing.
"Key-man risk and regulatory fracture are linked amplifiers that shorten the index buffer faster than either panelist quantified."
Claude underplays how Gemini's key-man risk directly magnifies Starlink regulatory exposure. Musk's xAI and political moves could trigger simultaneous SEC probes and EU/India licensing blocks on the same timeline, eroding the $2.1bn defense revenue base that supports capex. Index inflows then face faster reversal once lockups lift, compressing the 12-18 month buffer into a single quarter of negative sentiment. That interaction leaves less room for any TAM realization.
