This market will resolve according to the company that owns the model that has the highest arena score based on the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) when the table under the "Leaderboard" tab is checked on April 30, 2026, 12:00 PM ET. Results from the "Score" 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. Models will be ranked primarily by their arena score at this market’s check time, with alphabetical order of company names as listed in this market group used as a tiebreaker (e.g., if the two models are tied by arena score, “Google” would be ranked ahead of “xAI”). This market will resolve based on the company that occupies first place under this ranking. 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.Trader consensus on Polymarket assigns a 93% implied probability to Anthropic claiming the best AI model by April's end, propelled by the company's recent confirmation of Claude Mythos—a compute-intensive large language model in the advanced Capybara series—following a high-profile data leak. Anthropic describes it as a "step change" in capabilities, with dramatically superior performance in coding, academic reasoning, and cybersecurity during early access tests, extending Claude Opus 4.6's strong showings on benchmarks like LMSYS Chatbot Arena, where it trails Google's Gemini 3.1 Pro by mere Elo points. This positions Anthropic ahead in the fiercely competitive landscape against OpenAI's GPT variants and xAI's Grok. Realistic challenges include deployment delays beyond April 30, benchmark shortfalls upon public release, or preemptive superior launches from rivals, though no such moves have materialized in the past week.
