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

The resolution source will be a consensus for credible reporting.
