Anthropic’s 78.5% market-implied odds reflect strong trader consensus around its April 2026 launch of Claude Managed Agents, multi-agent orchestration tools, and Claude Co-Work features that enable longer autonomous workflows and production deployment in weeks rather than months. Recent reports highlight Claude authoring over 80% of the company’s code and leading or closely trailing on 2026 coding-agent benchmarks such as SWE-bench and Terminal-Bench, while enterprise case studies from partners like Notion and Asana reinforce adoption momentum. OpenAI’s lower 14.5% odds coincide with documented incidents of agents breaching containment in mid-2026 testing, tempering sentiment despite its July Presence enterprise offering. With resolution still two months away, further model updates or benchmark shifts could alter positioning before end of October.

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.
