Three trillion-dollar companies racing to public markets within months of each other. None of them profitable. A combined equity supply that could exceed $135 billion. Analysts drawing parallels to 1999. Welcome to the most consequential IPO cycle since the dot-com era.
On May 20, 2026, SpaceX filed its S-1 prospectus with the SEC, targeting a June 12 debut on Nasdaq under ticker SPCX with a valuation between $1.75 trillion and $2 trillion. Within hours, reports confirmed OpenAI is preparing its own confidential filing for a September listing approaching $1 trillion valuation. Anthropic, maker of Claude AI, follows with a pre-IPO valuation of $1.2 trillion.
The sheer scale is unprecedented. If SpaceX hits its $75 billion raise target, it would more than double the record set by Saudi Aramco’s $29.4 billion IPO. The combined exit value from these three offerings would exceed all venture-backed IPOs from the previous decade combined.
But the timing has sparked serious questions. Are we witnessing the infrastructure buildout of humanity’s AI future, or the final euphoric phase of a bubble about to burst?
The SpaceX S-1: A Company Transformed
For the first time in SpaceX’s 24-year history, the public can examine audited financials of Elon Musk’s aerospace empire. What they reveal is a company fundamentally transformed from the profitable rocket manufacturer it was just two years ago.
In 2024, SpaceX generated $791 million in net income—a profitable, rapidly growing aerospace company with dominant market position in commercial launches and satellite connectivity. Then came the xAI merger in February 2026, and everything changed.
The 2025 consolidated financials show $18.67 billion in revenue but a $4.94 billion net loss. First quarter 2026 revenue reached $4.69 billion, accompanied by a staggering $4.28 billion quarterly loss. The profitable rocket company had become a cash-burning AI conglomerate.
The segment breakdown tells the story. Starlink, SpaceX’s satellite connectivity business, accounts for 61% of 2025 revenue and remains highly profitable, generating $1.19 billion in operating profit in Q1 2026 alone. The Space segment (rockets and launches) lost $619 million. But the AI segment—the combined xAI and X platform operations—posted a $2.47 billion operating loss in a single quarter, with 2025 AI losses exceeding $6 billion.
Starlink’s extraordinary profitability is effectively subsidizing the AI bet. The question for public market investors: is that a smart allocation of capital, or a value-destroying distraction from a world-class aerospace business?
The Anthropic Deal and Orbital AI Ambitions
Buried in the S-1 is perhaps the most extraordinary customer contract in technology history. In March 2026, Anthropic signed a $1.25 billion per month agreement with SpaceX’s Colossus 1 data center through May 2029—a deal worth approximately $40 billion over its lifetime.
The Colossus facility houses 220,000 Nvidia GPUs across 300MW of power capacity, built in just 120 days. It represents SpaceX’s thesis that AI compute infrastructure is as strategically valuable as launch capability.
But there’s a catch that institutional investors have focused on: either party can terminate the contract with just 90 days notice. This isn’t recurring SaaS revenue—it’s a massive but revocable purchase order. If Anthropic builds its own infrastructure or finds cheaper alternatives, $40 billion in projected revenue disappears.
SpaceX’s longer-term AI vision is even more audacious. The S-1 discusses plans to deploy orbital AI compute satellites beginning in 2028, handling energy-intensive inference workloads in space with Starlink providing global connectivity. It’s a breathtaking concept that perfectly embodies the merger rationale: vertical integration of space infrastructure with frontier AI capabilities.
Whether public market investors will pay multi-trillion dollar valuations for a company burning billions while pursuing such speculative bets remains to be seen.
OpenAI: The Other Trillion-Dollar Gamble
While SpaceX at least has Starlink’s profitable revenue stream, OpenAI presents an even more precarious proposition. The company reaches $25 billion in annualized revenue as of February 2026—extraordinary growth from essentially zero just three years prior. ChatGPT has achieved genuine mainstream adoption, and enterprise customers are paying substantial sums for API access and premium subscriptions.
Yet OpenAI has not publicly disclosed profitability. Reports suggest the company continues operating at a loss despite massive revenue scale, primarily due to enormous compute infrastructure costs. When you’re paying hundreds of millions monthly for GPU clusters to train and run frontier models, profitability requires either dramatic improvements in computational efficiency or pricing power that may not exist in an increasingly competitive market.
OpenAI’s March 2026 funding round valued the company at $852 billion with a $122 billion capital raise—already approaching public company scale. Investment banks Goldman Sachs and Morgan Stanley are pushing for a $1 trillion IPO valuation this September.
The same banks, notably, are leading both the SpaceX and OpenAI offerings—creating an unprecedented scenario where the two largest IPOs in history are being underwritten simultaneously by the same financial institutions. It’s a concentration of deal flow and underwriting fees that has no parallel in modern equity capital markets.
1999 Parallels: Valid Warning or False Alarm?
“Back in 1999, we saw the same kind of thing where people were just rushing to get these IPOs out,” one market strategist noted, drawing the comparison that’s now dominating financial media coverage. The parallels are uncomfortable:
Massive companies racing to public markets at unprecedented valuations despite questionable or non-existent profitability. Investor enthusiasm driven by transformative technology narratives. Supply flooding the market precisely when sentiment approaches euphoric peaks. Retail investors desperate to participate in what feels like a once-in-a-generation opportunity.
William de Gale, portfolio manager at BlueBox Asset Management, articulated the core risk bluntly: “If OpenAI and Anthropic can’t make money, this whole thing falls apart. You could get OpenAI deciding to IPO itself in a couple of months, giving us the information that we realize it’s never going to make money, and that could be the end as well.”
The concern isn’t that AI lacks transformative potential—it’s that current valuations may require near-perfect execution combined with market conditions that remain extraordinarily accommodating. The technology might be revolutionary while the equity offerings still mark a market top.
Michael Burry’s Contrarian View
Not everyone accepts the bubble narrative. Michael Burry—the investor famous for predicting the 2008 financial crisis—told subscribers he believes investor sentiment and narratives will have a bigger impact than supply-driven pressures from the IPO wave.
Burry’s perspective suggests the IPOs themselves won’t mechanically cause a market correction. Instead, shifts in the prevailing narrative around AI’s economic viability could trigger broader repricing. By this logic, if SpaceX and OpenAI demonstrate robust public market demand and deliver on near-term execution milestones, sentiment could remain positive regardless of traditional valuation metrics.
The counterpoint is that narrative shifts often coincide with major capital markets events. IPO prospectuses force detailed financial disclosure that private markets don’t require. When public investors examine the actual unit economics, growth trajectories, and cash consumption patterns at these companies, reevaluation becomes inevitable.
Governance Red Flags
Beyond financial performance, institutional investors have raised serious governance concerns about the SpaceX structure. Elon Musk retains approximately 85% of voting power despite owning a much smaller economic stake—a dual-class structure that essentially grants him perpetual control regardless of public shareholder interests.
More controversial still is Musk’s Mars compensation package. The S-1 discloses a performance grant potentially worth over 1.3 billion shares if SpaceX successfully establishes a permanent Mars colony. At IPO valuations, this represents hundreds of billions in potential dilution for public shareholders, contingent on an objective that may take decades and whose achievement criteria remain vague.
On May 13, 2026—one week before the S-1 filing—New York City Comptroller Mark Levine, New York State Comptroller Thomas DiNapoli, and CalPERS CEO Marcie Frost sent a joint letter directly challenging these governance provisions. For America’s largest public pension funds to publicly rebuke a pre-IPO company’s governance structure is virtually unprecedented.
The message was clear: at these valuations and with these governance terms, major institutional investors have serious reservations about participating.
The $135 Billion Question
Combined new equity supply from SpaceX, OpenAI, and Anthropic could approach or exceed $135 billion—a volume of supply that public markets must absorb within a six-month window. For context, total VC-backed IPO proceeds in the entire previous decade don’t reach that figure.
Market mechanics matter. When supply overwhelms demand, prices adjust downward. The fear isn’t necessarily that these companies lack long-term value—it’s that the sheer volume of equity hitting markets simultaneously could force painful repricing regardless of fundamental quality.
Nasdaq implemented a Fast Entry rule effective May 1, 2026, allowing mega-cap IPOs to join the Nasdaq-100 within 15 trading days if they rank among the top 40 components by market cap. SpaceX would qualify immediately, forcing passive index funds to purchase tens of billions in shares regardless of valuation. This creates artificial demand that could temporarily support pricing, but the question remains: what happens when that initial absorption completes and the companies must attract ongoing investor interest based on actual performance?
The Execution Test Ahead
SpaceX lists on June 12. If the offering prices cleanly and trades up in initial sessions, it establishes market confidence that could support the OpenAI and Anthropic offerings following in Q3 and Q4. A stumble resets expectations across the entire pipeline.
For SpaceX, the key metrics investors will monitor include Starlink subscriber growth and ARPU trends, the Anthropic contract’s stability, progress on orbital AI infrastructure, and—critically—the path to AI segment profitability. Musk has suggested evaluating in-house GPU manufacturing to reduce costs; whether that’s viable at competitive economics will significantly impact financial projections.
For OpenAI, profitability timeline becomes the central question. Can the company leverage its current market position into sustainable unit economics, or will competition from open-source models and rival providers erode pricing power faster than efficiency improvements reduce costs?
Conclusion: Infrastructure Buildout or Market Peak?
The fundamental tension remains unresolved. Are we witnessing the IPO cycle that finances humanity’s transition to an AI-powered economy—comparable to railroad or electricity infrastructure buildouts in prior technological revolutions? Or are we experiencing the final euphoric phase of a speculative bubble, where unprofitable companies command unprecedented valuations during the brief window before reality reasserts itself?
Both narratives contain elements of truth. AI is genuinely transformative. These companies possess real technological capabilities and serve real customers generating real revenue. But valuation is always a function of expectations relative to execution, and current expectations appear extraordinarily optimistic.
What’s certain is that the next six months will prove decisive. By year-end 2026, we’ll have public financial disclosures, market reactions, and initial operating results from all three companies. Those data points will either validate current valuations or trigger the repricing that skeptics anticipate.
For investors, the stakes couldn’t be higher. For the companies, public markets represent both opportunity and accountability. And for the broader market, these mega-IPOs may indeed mark an inflection point—whether toward sustained AI-driven growth or toward the painful recognition that even revolutionary technology can be overvalued at precisely the wrong moment.
