OpenAI's sustained leadership in agent tooling and model releases drives the 70% implied probability for second-best AI agent lab by end of November, backed by its Agents SDK updates, GPT-6 Astra emphasis on computer use and cybersecurity, and broad developer adoption. Recent September launches, including Anthropic's Claude Fable 5.1 and Mythos 5.1 for coding agents alongside OpenAI's Codex CLI and prompt-cache improvements, highlight intense competition, while benchmark volatility across leaderboards shows OpenAI and Anthropic models trading top spots in planning and tool-use evals. A joint safety standards effort among OpenAI, Anthropic, and Google adds context on frontier coordination, though agent containment incidents earlier this year underscore execution risks. Meta's Muse expansions and open-weight gains from labs like Moonshot or DeepSeek represent swing factors that could shift sentiment ahead of November resolution.

Results from the "Rank" column under the "Agent Arena" Leaderboard tab at https://arena.ai/leaderboard/agent filtered for "Labs" will be used to resolve this market.
Models marked “AutoEval” at the applicable check time will not be considered, regardless of whether they display a rank or score.
AI companies will be ordered primarily by their Lab Rank at the market’s check time. If the results based on the lab ranking are ambiguous or unavailable, the relevant AI companies will be ordered according to their highest-ranking AI model in the leaderboard’s “Models” view. 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 AI lab/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 second place under this ranking.
The resolution source for this market is the arena.ai Agent Arena Leaderboard. 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 to "Other".
