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.Recent acquisition of Ari Weinstein’s company and team in October 2025 integrated his expertise in macOS AI interfaces directly into OpenAI’s product efforts, positioning him as a key contributor on Codex computer-use features and agent capabilities. Active public updates through May 2026, including shipped updates and team highlights, reflect ongoing commitment without signs of departure. Trader consensus at 81% for him remaining through year-end aligns with typical post-acquisition retention patterns and the absence of leadership shifts or competing opportunities in credible reporting, though product timelines and personal decisions introduce standard uncertainty in executive roles at AI labs.
