OpenAI files confidential S-1 with the SEC, says it has not decided on IPO timing yet

Summary

OpenAI has confidentially filed for an IPO with the SEC, though timing remains undecided and a public debut could come as soon as September. The filing follows Anthropic's own confidential submission, setting up a potentially record-breaking IPO year alongside SpaceX. Investor focus will be on gross margins, the path to profitability, and the sustainability of massive AI infrastructure spending, with both companies needing enormous capital that private markets may no longer fully supply.

• OpenAI filed confidentially for an IPO, with a possible listing as early as September depending on markets.
• OpenAI plans to allow employees to sell shares via a tender offer at its $850 billion valuation.
• Rival Anthropic also filed confidentially, valued around $900 billion.
• A SpaceX direct listing is expected soon, which together with the AI IPOs could create a multi-trillion-dollar IPO year.
• Investor concerns center on historic cash burn, negative gross margins, and uncertain path to profitability.
• OpenAI and Anthropic may need public markets because private funding sources are getting stretched.
• OpenAI's CFO indicated plans for a large retail investor allocation, with SpaceX serving as a potential test of retail demand.
