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 overwhelmingly favors Anthropic at 92.5% implied probability to hold the top AI model spot by April 30, driven by its Claude Opus 4.6-thinking variant leading the LMArena Chatbot Arena leaderboard with a 1504 Elo rating as of March 31—10 points ahead of Google's Gemini 3.1 Pro Preview. This edge stems from Claude's recent release showcasing superior reasoning, coding (e.g., 75.6% on SWE-bench), and agentic capabilities, outpacing rivals in crowdsourced battles. A March 26 data leak hyping the upcoming Claude Mythos as a "step change" further bolsters sentiment. Challenges could arise from surprise launches like OpenAI's GPT-5 updates or xAI's Grok iterations overtaking via rapid Elo shifts, though the 25-day window limits feasibility.
