This market resolves to YES if OpenAI publicly announces and releases a new flagship large language model (successor to GPT-4o or equivalent) by November 15, 2025.

Recent context: OpenAI has been regularly releasing major model updates. In September 2025, reports indicated that OpenAI shipped three significant upgrades including branching, unified Projects, and Codex IDE updates, suggesting continued development of their core models.

Resolution criteria: This market will resolve based on official announcements from OpenAI's website, blog, or social media accounts. The model must be a new flagship model (not just an incremental update) and must be made available to at least some subset of users (API access, ChatGPT Plus subscribers, or general public).
