Manifold MarketsRules
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.
