SpaceX, OpenAI, and Anthropic IPOs set to trigger unprecedented passive-money wave into US indices
Key Points
- SpaceX, OpenAI, and Anthropic are going public in rapid succession, with Nasdaq's new automatic index inclusion rules triggering billions in passive flows that will force existing stocks to be sold off.
- SpaceX's $1 trillion-plus valuation and dual-class structure cement Elon Musk's control of two mega-cap companies while masking $4.9 billion in annual losses across multiple business lines.
- Retail investors will enter these IPOs at stratospheric valuations, missing early exponential gains that earlier private investors and employees captured through equity compensation.
Summary
Three AI and Space Giants Head to Public Markets, Triggering Massive Passive Index Inflows
SpaceX, OpenAI, and Anthropic are rushing to go public in what the Financial Times calls an "unprecedented wave" of passive money flowing into US indices. Nasdaq's new rules, implemented this month, thrust the three companies straight into major indices upon listing, automatically triggering billions in flows from index funds and forcing investors to rebalance by selling rival stocks.
SpaceX's IPO is expected next month and will be the largest on record. OpenAI is filing IPO paperwork as soon as this week, and Anthropic plans to follow. The trio is positioned to raise tens of billions at a moment of relentless investor appetite for AI-linked companies.
The Musk concentration play
SpaceX's listing will cement Elon Musk's control of two of America's most valuable companies. SpaceX is expected to list at a valuation north of $1 trillion—higher than Tesla's current $1.34 trillion market cap. The company has dual-class share structures that preserve Musk's voting control, a structure also used by Berkshire Hathaway and News Corp. Government pension funds have griped about this arrangement, but as one observer notes, "If pension funds don't like SpaceX's structure, they don't have to buy shares."
The real earnings story
SpaceX reported a $4.9 billion net loss last year, though the figure conflates losses across multiple business lines including the X social media platform and capital-intensive Starship development. The company's existing Falcon Nine launch capability alone can sustain a substantial business—Starlink is running at a $10 billion to $20 billion annual run rate.
In its IPO filing, SpaceX forecasts $28.5 trillion in market opportunities, with $22 trillion attributed to enterprise software and data center services. The company recently struck a $1.25 billion-per-month deal with Anthropic to use its data centers for AI model training, illustrating how competitors can maintain symbiotic commercial relationships.
The retail IPO gap
Tesla went public at a $1.7 billion valuation in 2010. Anyone who held from day one saw roughly a 1000x return. SpaceX enters the public markets at a vastly higher valuation, meaning retail investors will miss the early stratospheric gains that built retail enthusiasm for Tesla. This structural advantage accrues to earlier private investors and employees with stock options—a compensation strategy both OpenAI and Anthropic have heavily relied on to preserve capital.
Musk received a $1 billion grant of performance-based restricted stock vesting upon establishing a permanent human colony on Mars with at least one million inhabitants.
