The 2026 IPO market is defined by three potential trillion-dollar listings: SpaceX, OpenAI, and Anthropic, which together represent over $3.5 trillion in potential market value.

SpaceX: Filed its S-1 on May 20, 2026, targeting a June 12, 2026 Nasdaq debut (ticker: SPCX) with a valuation of $1.75–$2 trillion.  It aims to raise up to $75 billion, potentially becoming the largest IPO in history.

OpenAI: Preparing a confidential IPO filing to list as early as September 2026, targeting a valuation exceeding $1 trillion and raising approximately $60 billion.

Anthropic: Scheduled to list in October 2026 with a valuation of over $380 billion.

SpaceX, OpenAI, and Anthropic are the primary candidates for the upcoming wave of trillion-dollar IPOs in 2026, with combined valuations nearing $3 trillion.  Market analysts and investors widely view these valuations as overvalued and potentially risky, citing the companies' current cash burn and lack of profitability.

SpaceX is targeting a $1.75 trillion valuation and a $75 billion raise, trading at over 100 times sales despite a $5 billion net loss in 2025.

OpenAI is projected to lose $14 billion in 2026 and is not expected to break even until 2029–2030.
Anthropic has surged to nearly $1 trillion in private markets but also expects to remain unprofitable until at least 2030.

Historical data indicates that large, hyped IPOs often underperform the S&P 500 in their first year, and the sheer volume of capital required for these listings could drain market liquidity.  Critics argue that the valuations rely heavily on narrative-driven future potential (such as orbital AI data centers) rather than current financial fundamentals.
