This market will resolve to "Yes" if Ari Weinstein ceases any employment or formal contractual involvement with OpenAI, for any length of time by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. This includes any termination, suspension, or withdrawal of his contractual or partnership obligations with OpenAI. An official announcement of Ari’s departure from OpenAI (e.g., a statement from OpenAI or Ari indicating he will no longer be engaged with OpenAI) will qualify, regardless of when the announced departure takes effect. The resolution source for this market will be a consensus of credible reporting.Ari Weinstein's integration into OpenAI via the October 2025 acquisition of his Sky team has positioned him as a key Member of Product Staff leading Computer Use and frontier interface efforts, including Codex features and macOS integration for ChatGPT agents. His active contributions to recent advancements, such as enhanced computer history tracking and automation capabilities highlighted in August 2026 reporting, reflect strong alignment with OpenAI's push toward practical AI agents. This recent commitment, combined with the absence of reported conflicts or leadership shifts, underpins the market-implied 69.4% odds against departure by year-end 2026, as traders weigh his central role in competitive AI tooling against typical post-acquisition retention patterns in the sector.
