Next Claude Opus Model (5.6+): Text Arena Debut?
Screened using the explicit question date; payout timing still follows the rules.
Contract resolution rules
Predicts whether the next Claude Opus 5.6+ model reaches a score of at least 1540 on the Arena.AI Text Arena Overall (style control off) leaderboard within one day of its first appearance, by June 30, 2027.
Conditions for a winning outcome
Resolves Yes if a model whose name or identifier includes Opus and version 5.6+ first appears on the leaderboard and its Score column value under Text Arena | Overall (style control off) is at least 1540 at 12:00 PM ET on the calendar date following first appearance. AutoEval-labeled scores do not count. If multiple models are added on the same calendar date (ET), the highest-scoring model is used. Models added on the calendar date following the initial qualifying model's first appearance are not considered. If the leaderboard is unavailable at that time, resolution uses the first subsequent available score within seven days of first appearance.
Exclusions and exceptions
Resolves No if the qualifying model is not displayed on the leaderboard at 12:00 PM ET on the day after first appearance (including if removed and not re-added), its score is below 1540, it is AutoEval-labeled, the model name or version excludes Opus or 5.6+, or no qualifying model appears by June 30, 2027, 11:59 PM ET. Models added on the calendar date following the initial qualifying model's first appearance are excluded. Scores from other tabs, columns, or with style control on do not qualify.
Timing & resolution
The deadline is 12:00 PM ET on the calendar date following the date the qualifying model first appears on the leaderboard. If the leaderboard is unavailable then, the first subsequent available score within seven days of first appearance is used. If no qualifying model appears by June 30, 2027, 11:59 PM ET, the market resolves No.
Ambiguities in the rules
The rules do not define what constitutes a model being 'first added' if it appears incrementally or partially on the leaderboard. They also do not clarify whether a model appearing on the leaderboard at exactly 12:00 PM ET on the following day but with a timestamped update just after that moment would count.

Event contracts and stock returns
A company’s share price, this event’s probability and the return on an event contract answer different questions. A correct company thesis can still miss a contract’s deadline or its exact conditions.
