Polymarket
This market tracks which company will own the second-ranked AI model according to the Chatbot Arena LLM Leaderboard's Style Control On ranking at the end of June 2026. On Polymarket, Anthropic holds 81.5% probability of securing the #2 position, while Google stands at 12.0%. The resolution will be determined by checking the Text Arena Overall Leaderboard tab at lmarena.ai on June 30, 2026 at 12:00 PM ET, with ties broken by Arena score and then alphabetical order. Watch for major model releases and leaderboard updates leading up to the June 30, 2026 resolution date.
This market will resolve according to the company that owns the model that has the second-highest arena rank (Style Control On) based on the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) when the table under the "Leaderboard" tab is checked on June 30, 2026, 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 on 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 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 system. 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.
Prediction market odds on Polymarket reflect real-time consensus from traders betting capital on AI model rankings, whereas analyst forecasts typically rely on published research and expert opinion. Markets often price in faster-moving signals—such as model release dates, benchmark results, and competitive positioning—than traditional analyst reports. The current market probability for the leading outcome provides a dynamic, crowd-sourced view that complements but differs from static analyst predictions, offering traders an alternative gauge of which company is most likely to secure the number-two AI model position by resolution.
The market resolves on Jun 30, 2026, marking the official end of the prediction window. Resolution hinges on identifying which company operates the second-ranked AI model as of that date, based on credible benchmarks, model releases, and industry consensus at that time. The specific criteria and data sources used to determine the ranking are established in the market's resolution rules. Traders should review those guidelines carefully to understand how the outcome will be adjudicated and which company's model will be deemed number two.
Major catalysts include new model releases from leading AI labs, updated benchmark results showing relative capability rankings, announcements of significant funding or partnerships, and public statements about model roadmaps. Breakthroughs in reasoning, multimodal performance, or specialized domains could shift perceptions of which company holds the number-two position. Regulatory developments, talent moves, and competitive product launches also influence market pricing. As we approach end of June 2026, clarity on model availability, real-world performance data, and industry consensus will likely drive final price adjustments before resolution.
