OpenAI’s push for a $1 trillion-plus valuation has emerged as the main factor behind the 87% market-implied odds against a listing before 2027. After confidentially filing with the SEC in June 2026 and initially targeting a late-2026 debut, CEO Sam Altman rejected adviser recommendations to accept a lower price amid tech-market volatility following SpaceX’s IPO performance. The company’s last private round valued it at roughly $852 billion, while it continues posting heavy losses against multi-hundred-billion-dollar compute commitments. Statements from OpenAI emphasize that certain strategic moves remain easier as a private entity, and no public timeline has been set despite banker involvement. Traders see these dynamics, plus competitive pressure from rivals like Anthropic, as tilting consensus toward a 2027 window.

This market will resolve to “Yes” if OpenAI completes an initial public offering (IPO) valued at $1 trillion USD or higher at the time of the IPO by December 31, 2026, 11:59 PM ET. Otherwise, it will resolve to “No.”
An “initial public offering (IPO)” refers to the first sale of OpenAI’s equity securities to the public through a regulated stock exchange.
OpenAI will be considered to have achieved a $1 trillion valuation if the market capitalization implied by the IPO offering price multiplied by the total number of outstanding shares equals or exceeds $1 trillion USD.
Announcements, filings, or planned IPOs that do not result in public trading by that time will not qualify. Private funding rounds, secondary share sales, or employee-share transactions will not be considered. A direct listing or merger via SPAC will qualify only if it results in OpenAI’s common shares becoming publicly traded for the first time on a major exchange.
If OpenAI’s IPO is priced before the resolution deadline but public trading has not yet commenced, the market may remain open for up to 30 calendar days to determine whether the IPO is completed.
If OpenAI is acquired, dissolved, or merged into another entity before an IPO occurs, this market will resolve to “No.” In the event of a restructuring, the market will resolve based on the entity legally recognized as OpenAI’s successor will
