Fears and frenzy mount as SpaceX, OpenAI and Anthropic prepare for a $4T AI IPO wave

SpaceX, OpenAI, and Anthropic are poised to launch trillion-dollar IPOs, potentially reshaping global corporate valuations. SpaceX filed for a Nasdaq listing with a valuation range of $1.75 trillion to $2 trillion, aiming to raise $75 billion—the largest U.S. IPO in history—though it reported $4.28 billion in losses over three months. The company’s valuation hinges on future ambitions in satellite broadband (Starlink), reusable rockets, AI infrastructure, and Mars colonization, though critics question its profitability and transparency. Anthropic, meanwhile, is nearing profitability and accelerating enterprise demand for its AI model, Claude, which could boost demand for GPU and AI networking infrastructure from companies like Nvidia and Broadcom. A successful near-trillion-dollar IPO for Anthropic could validate the ‘profitable AI model’ narrative, sustaining long-term investor interest. However, risks remain, including stalled profitability or slower enterprise adoption, which could dampen market enthusiasm. OpenAI’s potential IPO, though not yet confirmed, would further amplify the AI frenzy, with Wall Street positioning for a wave of listings that could collectively absorb hundreds of billions in market capitalization. Investors are divided: some see transformative growth potential, while others warn of peak market exuberance and overvaluation. Analysts cite historical data showing mega-IPOs underperform by 3–5% annually, raising concerns about SpaceX’s $1.75–$2 trillion valuation given its multi-business complexity and unproven revenue streams. The upcoming IPOs mark a turning point for Silicon Valley, reviving excitement after years of subdued tech listings. Yet, the high valuations and speculative bets on future growth—rather than current profitability—have sparked scrutiny. Critics argue the market may be pricing in unrealistic expectations, particularly for SpaceX, where Starlink and Starship cash flows could force a valuation re-rating if growth stalls. The wave of AI-driven IPOs could redefine public investor access to the sector but also signal potential market peaks.
