Traders assign Anthropic a commanding 71.2% implied probability for fielding the strongest large language model by the end of June because its Claude Opus 4.7 and Mythos preview have posted leading results on agentic coding benchmarks such as SWE-bench and advanced reasoning evaluations. These releases, paired with expanded 1-million-token context handling and demonstrated vulnerability discovery in controlled testing, have strengthened the company’s edge in enterprise-grade performance. OpenAI’s GPT-5.5 launch in late April narrowed some gaps on general-purpose tasks, while Google’s Gemini 3.1 updates improved speed and multimodal capabilities, yet neither has displaced Anthropic’s current lead in the metrics most relevant to frontier-model assessments. With roughly six weeks remaining, any further benchmark gains or capability demonstrations from Anthropic could solidify its position 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.
