Understand this market
This market is asking: which company — Anthropic, OpenAI, or Meta — will have the single best AI agent according to one specific public ranking on June 30, 2026? An 'AI agent' is an AI that can take actions on your behalf, like browsing the web, writing code, or completing multi-step tasks — not just answering questions. A win for Anthropic means their model sits at the top of that leaderboard on that day; a win for OpenAI or Meta means the same for them.

Resolution Criteria
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 June 30, 2026, 12:00 PM ET. Results from the "Rank" column under the "Agent Arena" Leaderboard tab at https://arena.ai/leaderboard/agent will be used to resolve this market. 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 “xAI”). 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.
