Trader consensus on Polymarket overwhelmingly favors Anthropic with 100% implied probability for possessing the top AI model by April 30, 2026, driven by Claude Opus 4.7's April 16 release, which surged to the #1 spot on the LMArena Chatbot Arena Text Overall leaderboard at 1504 Elo—well ahead of OpenAI's GPT-5.5 (ranks 7-10) and others. This lead stems from superior demonstrated capabilities in coding benchmarks like 82% on SWE-bench Verified, bolstered by no major rival announcements in the past two weeks amid fierce competition from Google Gemini 3.1 and xAI. With resolution imminent at noon ET via leaderboard snapshot, upset scenarios are slim: a surprise competitor model release or rapid user-voted shifts, though leaderboard stability and time constraints make these highly improbable.

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.
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 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.
