Trader consensus on Polymarket assigns Anthropic a 69% implied probability of fielding the top large language model by June 30, driven by Claude Opus 4.7's dominance on the Arena.ai (formerly LMSYS Chatbot Arena) leaderboard since its mid-April launch, where it holds the highest Elo scores in text, code, and agentic tasks—often leading rivals by 30+ points. OpenAI's GPT-5.5 release on April 23 delivered strong gains in autonomous agents and math benchmarks but fell short of overtaking Claude overall, dropping its odds to 6.5%; Google's Gemini 3.1 Pro remains competitive at 22% amid multimodal advances, buoyed by March updates. Anthropic's biweekly iteration pace in 2026 sustains its edge, though Google I/O previews could preview Gemini 4 shifts before resolution.

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.
