This market asks whether Anthropic’s `claude-opus-4-6-thinking` will sit at the top of the Chatbot Arena LLM Leaderboard on June 13, 2026 at 12:00 PM ET. It is less about a single benchmark score and more about which model is ranked first on a public comparison table at a specific check time, so small changes in leaderboard ordering can matter.
The outcome is determined by the `Rank` column on the `Text Arena | Overall` leaderboard at lmarena.ai, with style control turned off. If `claude-opus-4-6-thinking` is the highest-ranked model at the check time, the market resolves Yes; if any other listed model is ahead of it, the answer is No. The market also says that no new model will be added after creation, and anything not explicitly listed is grouped into `Other`.
There is real uncertainty here because AI leaderboards can shift as models are updated, compared under different settings, or overtaken by a rival release before the check date. The name in the title points to a specific Anthropic model variant, and the market is really testing whether that exact model name can keep or reach the top spot by the deadline. Readers watching this market are following a narrow definition of “best” that depends on one public ranking rather than a broader judgment about model quality.
The biggest price moves will usually come from changes in the Chatbot Arena ordering for the named model and its closest competitors, especially if `claude-opus-4-6-thinking` climbs, slips, or gets edged out by a tie-break. Because the resolution uses the leaderboard at one exact time, any movement in rank, score, or tie-breaking position close to June 13, 2026 can matter a lot. The market can also react if the leaderboard layout, style-control setting, or availability of the resolution page becomes an issue.

View marketThe current market price implies roughly a 85% chance for the leading outcome, based on live Polymarket pricing. That number is not a prediction from PredictionNinja and it is not a guarantee; it is the current crowd-priced view of the market and can change quickly when new information appears.
Before the deadline, the key thing to verify is the exact `Text Arena | Overall` ranking on lmarena.ai at 12:00 PM ET on June 13, 2026, with style control off, since that is the stated source of truth. If the site is unavailable at check time, the market rules say it remains open until the source can be checked, so the state of the leaderboard page itself matters as much as the ranking. Watch for tie situations too, because the rules use arena score and then alphabetical order of the full model name as tiebreakers, which could decide the winner if ranks are equal.

This market is currently listed with an end date of Jun 13, 2026. Market timelines can change if the underlying event is postponed, rescheduled, or resolved early.
This market will resolve according to the model that has the highest arena rank based on the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) when the table under the "Leaderboard" tab is checked on the specified date, 12:00 PM ET. Results from the "Rank" column under the "Text Arena | Overall" Leaderboard tab at https://lmarena.ai/leaderboard/text with style control off will be used to resolve this market. No new model will be added to this market after market creation. Any model not explicitly listed in this market will be encompassed under the "Other" option. 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 model names as listed in this market group (full string, including suffixes such as “-thinking”) will be used as a final tiebreaker (e.g., if two models remain tied, “claude-opus-4-6” would be ranked ahead of “claude-opus-4-6-thinking”). This market will resolve to the model that comes first according to this order. The resolution source for this market is the Chatbot Arena LLM Leaderboard found at https://lmarena.ai/. 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.
Probability signal
The current price implies a strong favorite, so new information would need to be meaningful to move the market sharply.
Liquidity context
Liquidity is present but not especially deep, so spreads and order-book movement still matter.
Spread
The bid-ask spread is wider, so the headline probability may be less precise than it looks.
Recent movement
The 24h move is notable, so recent news or market activity may have changed trader expectations.
The current displayed probability is 85%, based on the latest normalized Polymarket data available to PredictionNinja.
The rules and resolution criteria are pulled from the market description provided by Polymarket when available.
