Resolution rules

If Anthropic has the top-ranked LLM on Sep 30, 2026, then the market resolves to Yes. If two models are tied under Rank (UB), then the model with the highest Arena Score will win. If two models are still tied after that, then the model with the most votes will win. If two models are still tied after that, the model that was released earlier will win.
