This market tracks which company—Anthropic or Google—will have the highest-ranked AI model according to the Chatbot Arena LLM Leaderboard at the end of December 2026. Currently, Polymarket gives Anthropic a 41.5% probability of having the best model, while Google is at 38.5%. The resolution source for this market is https://lmarena.ai/, specifically the leaderboard ranking as of December 31, 2026, at 12:00 PM ET. Keep a close eye on the leaderboard rankings as the December 31, 2026 deadline approaches, as the final positions will determine the outcome of this market.
This market will resolve according to the company which owns the model which has the highest arena rank based off the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) when the table under the "Leaderboard" tab is checked on December 31, 2026, 12:00 PM ET. Results from the "Rank" section on the Leaderboard tab of https://lmarena.ai/leaderboard/text with the 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 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 first 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 resolve based on the first check after it becomes available. If it becomes permanently unavailable, this market will resolve based on another resolution source.
Currently, the odds in this market suggest a different outlook than many analyst forecasts regarding AI supremacy. While some analysts predict a more distributed landscape, this market shows a strong leaning towards a particular leader. The discrepancy could stem from the incentive structure of prediction markets, where traders have financial stakes in accurately forecasting the outcome. This creates a potentially more focused and informed prediction than traditional surveys or expert opinions, as traders are actively researching and weighing information to maximize their potential returns. It's important to note that both sources offer valuable perspectives.
On Polymarket, this market is priced through a continuous double auction, meaning traders can buy and sell shares representing their belief in each outcome. The price of a share reflects the market's collective probability of that outcome occurring. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. As traders exchange shares, the prices adjust to reflect new information and changing sentiment. The higher the price of a share, the more likely the market believes that outcome is to happen. This dynamic pricing mechanism ensures that the market odds are constantly updated based on the latest available information and the aggregated wisdom of the crowd.
This market resolves around Dec 31, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The determination of which company has the “best” AI model will be based on widely accepted benchmarks and evaluations published by reputable AI research organizations and industry experts. The resolution will consider factors such as performance on standard AI tasks, innovation in AI techniques, and overall impact on the field. The goal is to identify the company whose AI model demonstrates the most significant advancements and capabilities at the time of resolution.
Several signals or events could significantly impact this market. Major breakthroughs in AI research from any of the leading companies, such as the release of a significantly more powerful or efficient model, would likely cause shifts in the odds. Announcements regarding partnerships or acquisitions involving key AI players could also influence trading activity. Regulatory developments impacting the AI industry, or significant changes in investment trends, could also play a role. Unexpected setbacks or failures in AI development for any company would likely decrease their chances in this market.
