This market asks whether Anthropic will be the company behind the second-highest ranked coding model on the Chatbot Arena leaderboard at the end of June 2026. It is a narrow, source-based question, so the answer depends less on headlines than on how the leaderboard looks at the exact check time.
The market resolves from the "Text Arena | Coding" table on Chatbot Arena, using the rank column with style control off at 12:00 PM ET on June 30, 2026. The specific question is not whether Anthropic has a strong coding model in general, but whether the company’s model is sitting in second place on that date, behind whatever model is ranked first and ahead of the rest. If two models share a rank, the rules say the higher Arena score breaks the tie, and if that still does not settle it, company names are used as the final tiebreaker.
Anthropic is one of the leading companies in frontier AI, and coding performance is a visible benchmark for how useful its models are for software tasks. The uncertainty here is about relative standing: Anthropic could be second, but rivals such as Google, OpenAI, xAI, or others could move ahead depending on future model releases and leaderboard changes before the deadline.
Price can move if Anthropic releases a new coding-focused model, if a competitor improves enough to overtake it, or if Chatbot Arena updates the leaderboard ranking in a way that changes the company in second place. Because the market is tied to one public leaderboard and a specific time check, even small rank changes, exact-score tie situations, or a newly posted model can matter. Any change in the arena’s availability near the resolution time can also affect how this market is ultimately settled.
The current market price implies roughly a 89% 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.

View marketReaders should watch the Chatbot Arena LLM Leaderboard on the "Text Arena | Coding" page and confirm the rank column at the exact June 30, 2026, 12:00 PM ET check time. The key details to verify are the style-control setting, the company that owns the model in second place, and the tie-breaking rules for equal rank or equal score. One part of the posted fallback language is truncated in the market description, so the exact procedure if the source is unavailable for a long period should be checked in the full rules before relying on a resolution edge.

This market is currently listed with an end date of Jun 30, 2026. Market timelines can change if the underlying event is postponed, rescheduled, or resolved early.
This market will resolve according to the company that owns the model that has the second-highest arena rank based on the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) when the table under the "Leaderboard" tab for "Coding" is checked on June 30, 2026, 12:00 PM ET. Results from the "Rank" column under the "Text Arena | Coding" Leaderboard tab at https://arena.ai/leaderboard/text/coding-no-style-control with style control off 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 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 “xAI”). This market will resolve based on the company that occupies second place under this ranking. 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 modest, suggesting the market has not repriced dramatically in the latest feed.
