This market will resolve according to the company that owns the model that has the highest rank based on the Agent Arena Leaderboard (https://arena.ai/leaderboard/agent) when the table under "Agent Arena" filtered for "Models" is checked on October 31, 2026, 12:00 PM ET. Results from the "Rank" column under the "Agent Arena" Leaderboard tab at https://arena.ai/leaderboard/agent filtered for "Models" will be used to resolve this market. Note: Models marked “AutoEval” at the applicable check time will not be considered, regardless of whether they display a rank or score. Models will be ordered primarily by their leaderboard rank at the market’s check time. If two or more models are tied on rank, they will be ordered by which model is listed higher on the leaderboard. If a tie still remains, alphabetical order of company names as listed in this market group will be used as a final tiebreaker (e.g., “Google” would be ranked ahead of “SpaceXAI”). This market will resolve based on the company that occupies first place under this ranking. The resolution source for this market is the Agent Arena Leaderboard found at https://arena.ai/leaderboard/agent. If this resolution source is unavailable at check time, this market will remain open until the leaderboard comes back online and will resolve based on the first check after it becomes available. If it becomes permanently unavailable, this market will resolve based on another resolution source.Anthropic's edge in the market stems from its April 2026 launch of Claude Managed Agents and the "2026 State of AI Agents" report, which highlighted enterprise deployments and multi-agent systems for complex workflows. These moves, combined with strong SWE-bench performance and safety-focused infrastructure, have driven trader consensus toward Anthropic at 63.5% implied probability. OpenAI trails at 33.5% despite Codex expansion and the July Presence platform for trusted agents, amid reports of capability incidents. Other entrants remain marginal as traders weigh Anthropic's practical agent tooling against broader OpenAI ecosystem adoption ahead of the late-October resolution.
