One-time source collection
Inspect the evidence behind the contract
Collect exact source passages and export them with this contract’s identity. No sign-in required.
Recognized complete terms receive a rule-based reading, including supported Fed, GDP, Core PCE/Core CPI monthly and Bitcoin threshold contracts. Election pair readings are available in Compare. Standard collection reads the named Federal Reserve calendar, BEA GDP overview or the fixed PCE overview for recognized Core PCE terms. The PCE overview is context; the exact monthly figure still needs its release. The optional scope adds the exact official Fed decision, GDP release or selected PCE/CPI monthly release when available. Core CPI collection retains terms only until you explicitly request BLS release evidence. A candle query plan does not fetch candles. Other contracts retain their venue text and explain what is missing.

What defines this contract
Description & declared source
This market will resolve according to the company which owns the model which has the highest arena rank based on the arena.ai Text Arena (Overall) when the table under the "Leaderboard" tab is checked on October 31, 2026, 12:00 PM ET. Results from the "Rank" column under the "Text Arena | Overall" Leaderboard tab at https://arena.ai/leaderboard/text/overall-no-style-control with style control off (Adjustments: None) and 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 their Arena score, including any underlying, unrounded, granular values reflected in the data below 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., if the two models are tied by exact arena score, “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 arena.ai Text Arena (Overall). 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".
