Elon Musk is now the world’s first trillionaire. SpaceX’s historic debut on the stock market on Friday launched the CEO to unprecedented levels of wealth; his personal fortune now amounts to $1.1tn, an increase of more than $62bn since the previous day, according to Forbes.
The rocket, satellite and AI company raised $75bn from its record-breaking initial public offering (IPO), and is now valued at $2.1tn after its first day of public trading.
Musk was already the world’s wealthiest person. In the days before SpaceX officially went public, his net worth hit $782bn, dropping by $50bn in one month due to a decline in Tesla’s share price, according to Forbes. However, the figure represents a huge leap from a decade ago, when the tech executive’s net worth hovered around $14bn – and an even bigger jump compared with 15 years earlier, when he was worth just $680m, according to Forbes.
It can be hard to conceptualize such exorbitant wealth. To drive home just how much money $1.1tn is: only about 21 countries’ yearly economic output exceeds $1tn. Even Musk’s birthplace isn’t part of that elite club; South Africa’s output of goods and service is closer to $480bn. A trillion dollars is enough to buy 243bn gallons of gasoline. (That’s more than the nearly 137bn gallons Americans used last year.)
SpaceX’s stock soared after its debut. At market close, at 4pm ET, its share price was $161, up 19% from its initial price of $135 per share. SpaceX had opened at $150 a share before peaking at $176 at midday.
The vast majority of Musk’s money is tied up in stocks and equity, and isn’t available as cash he can quickly spend. His portfolio of companies includes Tesla, the electric car maker, and xAI, the AI startup that was folded into SpaceX earlier this year.
Musk’s fortune is unprecedented, not just for its size but the speed at which it grew.
“If you look at a graph, it looks like a hockey stick. It’s only in 2020 that his personal net worth truly went bonkers,” says Quinn Slobodian, a history professor at Boston University and the author of Muskism: A Guide for the Perplexed. Around 2020 was when Musk first became the world’s wealthiest person and Tesla the world’s most valuable car company.
“Musk has a proven track record in creating sectors out of nothing,” Slobodian says. There’s a sense to “never bet against Elon – he’ll always make you money”, he adds.
A few months before SpaceX’s stock market debut, Musk wrapped his AI startup, xAI, into SpaceX in a record-breaking deal. SpaceX has proposed launching up to 1m datacenters into space, as part of its ultimate goal of establishing colonies on the moon and Mars.
This lean into AI is what’s allowed Musk to claim such high valuation for SpaceX – because many investors now believe “AI is such a once-in-a-millennium opportunity that it merits these extravagant expectations”, says Mihir Desai, a professor at Harvard Business School. Desai says the space business alone wouldn’t have generated such excitement.
SpaceX is running up billions of dollars in losses, and its prospectus warns it may never become profitable. Many great businesses start off losing money but “the real question is how people come to believe that the future is so, so bright that those losses will not just turn into profits, but will turn into really massive profits”, Desai says. “That’s a story about not just SpaceX, but really about AI.”
Musk has won investor confidence through the stratospheric success of his previous endeavors, which faced serious doubts. (A $10,000 investment in Tesla on the day of its IPO, in 2010, would be worth more than $2m this year.)
Desai describes Musk’s most loyal investors as belonging to a “financial cult” – and argues they believe he is “so damn brilliant that he’ll make it work even if the current product is crap and he has to spend a lot to get there”.
The AI portion of SpaceX lost $6.4bn last year – in part due to the cost of higher computing expenses for building and operating AI models. But investors may fear missing out more than they fear losses: “You don’t want to sit on the sidelines. And so even if you think it’s crazy, you have to play,” Desai says.
Musk is also able to consolidate his wealth through his continuing influence. He is not selling any of his shares in the SpaceX offering and will retain more than 82% of the company’s voting shares. That means it will be almost impossible to unseat him from the company, and he will be relatively insulated from shareholder pressure.
SpaceX’s IPO comes amid recent announcements by OpenAI and Anthropic that they are going public, although it’s unclear when exactly they will do so. All three companies’ fates are tied up with AI.
If the AI gamble doesn’t work out, “people are going to start to get cold feet and withdraw their investments”, Slobodian says. “This is not an ironclad fortune. We may see the world’s first trillionaire be the world’s first former trillionaire in a pretty short duration.”
Four leading AI models discuss this article
"SpaceX's valuation assumes AI will convert billions in losses into outsized profits faster than historical space or auto precedents allow."
The reported SpaceX IPO at a $2.1tn valuation after raising $75bn hinges on bundling xAI's speculative data-center ambitions into a loss-making space business. Musk retains 82% voting control while the AI segment posted $6.4bn losses last year and the prospectus flags possible permanent unprofitability. This structure concentrates upside and downside in one narrative-driven bet rather than diversified cash flows. Historical parallels like early Tesla show rapid re-ratings are possible, yet the speed from $782bn to $1.1tn net worth in a single day underscores how fragile the AI premium remains if monetization timelines slip.
Musk's Tesla investors earned 200x returns despite years of losses and skepticism, suggesting the same 'financial cult' dynamic could sustain SpaceX's multiple even if near-term profits stay elusive.
"SpaceX’s IPO is overvalued and relies on speculative AI-driven growth rather than credible, near-term cash flows."
The article treats SpaceX’s IPO as a triumph of AI optimism and Musk’s brand. The strongest counter is that a $2.1tn valuation on day one hinges on an uncertain profitability path for a currently loss-making, capital-intensive business. SpaceX lacks visible near-term free cash flow, and the IPO proceeds must fuel ongoing expansion and potential future dilutions. Governance risk is elevated: Musk retains >82% voting control, limiting minority protections if bets sour. The piece omits funding risk, regulatory/commercial space hurdles, and competition from aerospace/defense players. If AI demand cools or launch economics disappoint, the valuation could revert sharply.
The AI-monetization narrative and SpaceX’s first-mover advantage could justify the lofty multiple if the bets pay off; governance risk may be tolerable for investors who gain from potential breakthroughs. However, the upside hinges on outcomes far from assured.
"The $2.1tn valuation is untethered from current cash flows and relies entirely on the successful integration of speculative AI compute into a volatile, high-capex space business model."
The SpaceX IPO at a $2.1tn valuation is a masterclass in narrative-driven capital allocation, but it ignores fundamental gravity. By folding xAI into SpaceX, Musk has effectively created a 'black box' conglomerate where space launch revenue—which is capital-intensive and cyclical—is being cross-subsidized by speculative AI compute costs. A $2.1tn valuation implies an astronomical forward P/E ratio that assumes perfect execution in both orbital infrastructure and AGI development. While the 'cult' of Musk supports this, the $6.4bn in AI losses suggests that SpaceX is no longer just a rocket company; it is a leveraged bet on AI infrastructure that risks massive dilution if the 'space-based datacenter' thesis fails to achieve commercial viability.
If SpaceX successfully achieves low-latency, orbital-based compute, it would effectively bypass terrestrial geopolitical constraints, creating a monopolistic moat that justifies even a $2.1tn valuation.
"SpaceX's $2.1tn valuation is 80% bet on AI-in-space narrative and 20% on proven launch economics, making it vulnerable to AI hype deflation even if the core business performs."
The article conflates wealth creation with value creation. A $2.1tn valuation for a company burning $6.4bn annually in AI losses, with no clear path to profitability, is a valuation bet on Musk's narrative, not SpaceX's fundamentals. The 19% pop on day one is typical IPO euphoria, not validation. What's genuinely interesting: SpaceX's core launch business is profitable and growing; the AI merger inflated the valuation by absorbing xAI's losses into a higher-multiple vehicle. Musk's 82% voting control means no accountability mechanism if the AI thesis fails. The real risk isn't whether Musk is brilliant—it's whether investors can distinguish between his track record (Tesla, proven) and his bets (space datacenters, unproven).
SpaceX's launch business alone justifies a substantial valuation, and Starship's reusability could genuinely disrupt aerospace economics; the AI integration may be premature but not necessarily irrational if you believe AI compute demand will require off-world infrastructure within 5-7 years.
"xAI integration creates simultaneous cash-burn pressure on SpaceX that prior Musk bets never faced."
Claude flags the launch business profitability but misses how xAI's $6.4bn losses will compete directly for Starship capacity and capital. Any delay in reusable orbital compute past 2027 forces simultaneous cash drains, accelerating dilution even with Musk's control. This cross-subsidy dynamic differs from Tesla's single-bet history and remains unpriced in the $2.1tn multiple.
"Cross-subsidy risks exist, but upside/downside hinges on Starship utilization timing and resulting dilution, not just an unpriced narrative premium."
Responding to Grok: you’re right that cross-subsidy risks exist, but calling them 'unpriced' undervalues the IPO narrative. The prospectus explicitly frames AI losses as funding for growth, not a free option. The real risk is timing and utilization: if Starship capacity or orbital compute demand slows beyond 2027, cash burn accelerates and dilution compounds, while 82% control limits minority discipline. The market may be underpricing a non-linear downside path.
"The AI-SpaceX merger is a strategic play to bypass terrestrial regulatory and energy constraints rather than a simple capital cross-subsidy."
Gemini and Claude assume the AI integration is a 'black box' or 'premature' burden, but they ignore the regulatory arbitrage. By tethering xAI to SpaceX, Musk effectively shields AI compute from terrestrial energy and data sovereignty constraints. This isn't just a capital allocation strategy; it's a structural moat against future AI regulation. The $2.1tn valuation isn't pricing current earnings, it's pricing the ability to operate outside the jurisdiction of traditional data-center oversight.
"Regulatory arbitrage requires operational success; without it, Musk's control enables value destruction, not protection."
Gemini's regulatory arbitrage angle is clever but overstated. Orbital compute still requires ground stations, power agreements, and launch licensing—all terrestrial friction points. More critically: if xAI's losses accelerate past 2027 without orbital revenue, Musk's 82% control becomes a liability, not a shield. He can dilute at will, but that destroys minority valuations faster than any regulator. The real unpriced risk is execution risk masquerading as regulatory moat.
The panel largely agrees that the SpaceX IPO at a $2.1tn valuation is over-reliant on Elon Musk's narrative and uncertain AI prospects, with significant risks including potential dilution, execution challenges, and unpriced downside paths.
