The Biggest Tech IPO in History
OpenAI filed a confidential S-1 with the SEC on June 8, 2026, targeting a NYSE debut as early as September 2026. Goldman Sachs, Morgan Stanley, and JPMorgan are leading the deal. At the last private valuation of $852 billion, an opening-day rally past $1 trillion is what analysts expect. If it gets there, it would be worth more than every company in the S and P 500 except Apple and Microsoft, the very firm that owns 27% of it.

Microsoft's stake is roughly 27% on a diluted basis, the product of a $13 billion multi-year investment. Under their revenue-sharing agreement, Microsoft receives approximately 20% of OpenAI's top-line revenue until the investment is recouped. That clause affects every IPO valuation model.

Anthropic filed its own confidential S-1 on June 1, 2026, targeting a valuation of $965 billion. If both companies list in the same window, institutional investors may be forced to choose between them, which could compress valuations for one or both.


:NOTE
The $14 billion projected 2026 operating loss is not a rounding error. OpenAI's inference costs alone are expected to reach $14 billion this year, up from $8.4 billion in 2025. Every ChatGPT query, every API call, costs real compute. The company's bet is that revenue grows faster than those costs, but it has not happened yet at scale.

The implied 35x forward revenue multiple is priced for a monopoly outcome that does not yet exist.
