PolymarketRules
This market will resolve to "Yes" if OpenAI officially changes its name to "OpenSI" by December 31, 2026, 11:59 PM ET.
- Otherwise, this market will resolve to "No".
- A qualifying name change requires OpenAI to adopt "OpenSI" as the official name of the company.
- Stylizations of the same name, such as "Open SI" or "OpenSI" followed by a corporate suffix (e.g., "OpenSI Group PBC"), will qualify.
- Renaming either OpenAI's operating company (OpenAI Group PBC) or its nonprofit parent (the OpenAI Foundation) to a name meeting these criteria will qualify.
- An official announcement by OpenAI within this market's timeframe that the company is changing its name to "OpenSI" will qualify, regardless of when the change goes into effect.
