This market will resolve to "Yes" if OpenAI’s full o3 model is made available to the general public by April 18, 2025, at 11:59 PM ET. Otherwise, this market will resolve to "No."

Intermediate or partial versions (e.g., o3-mini, o3-pro) will not count. However, the release of o3 itself — or a clearly named direct successor — will qualify.

For this market to resolve to "Yes," the full o3 model must be launched and publicly accessible, including via open beta or an open rolling waitlist. A closed beta or any form of limited/private access will not suffice. The release must be clearly defined and publicly announced by OpenAI as being accessible to the general public.

The "OpenAI o3 model" refers specifically to the full version of o3, explicitly named as such or clearly positioned as the successor to the o1 model.

The primary resolution source for this market will be official information from OpenAI, with additional verification from a consensus of credible reporting.
