Resolution criteria on PolyGram: 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.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.

The Chatbot Arena Leaderboard ranks large language models based on head-to-head comparison results from user interactions. This market resolves to whichever model holds the highest rank on the "Text Arena | Overall" leaderboard on 16 May 2026, using the style-control-off configuration. The current order book on Polymarket prices the "Other" category at 98% implied probability, reflecting substantial uncertainty about which specific model will lead eighteen months from now. This pricing suggests the market expects either continued dominance by an existing leader or emergence of a model not yet listed as an explicit option.
Historical leaderboard dynamics show rankings shift gradually rather than dramatically. OpenAI's GPT-4 and Anthropic's Claude variants have maintained top positions across multiple evaluation periods, though newer entrants periodically challenge incumbents. The 2% probability assigned to the explicit "best model" options reflects the difficulty in predicting which single architecture will achieve the highest Elo rating by mid-2026, given the rapid iteration cycles in the sector and the leaderboard's sensitivity to user preference distributions.
Key catalysts include major model releases from OpenAI, Anthropic, Google DeepMind, and Meta throughout 2024–2026. Leaderboard composition changes when developers submit models for evaluation, and ranking shifts depend on accumulated user votes rather than publication dates. Traders should monitor announcements of new model versions and track intermediate leaderboard snapshots, as the May 2026 snapshot represents a single point-in-time measurement that could favour whichever organisation releases a competitive model closest to the resolution date.
