Trader consensus on Polymarket heavily favors Anthropic at 88.5% implied probability for the top AI model by April 30, 2026, driven by Claude Opus 4.6's recent dominance of the LMSYS Chatbot Arena leaderboard with a leading 1504 Elo score in text tasks like coding and reasoning. This follows Anthropic's rapid 2026 shipment cadence—including Sonnet 4.6, Haiku 4.5, and Cowork agent tools—outpacing rivals amid previews of the "Mythos" model, hailed for step-change cybersecurity and academic benchmarks yet withheld from public release due to risks. OpenAI's GPT-5.4 trails closely at 7%, with Google's Gemini 3.1 Pro competitive but stagnant; no major catalysts loom for challengers before resolution, though surprise launches could shift dynamics.
