Trader consensus strongly favors Anthropic (55.5% implied probability) for the second-best AI model by end of April, driven by Claude 3 Opus's consistent #2 ranking on the LMSYS Chatbot Arena leaderboard behind OpenAI's GPT-4 Turbo, with superior Elo scores in reasoning and coding benchmarks. Google trails at 31%, bolstered by Gemini 1.5 Pro's long-context capabilities and multimodal features, though it lags in head-to-head chats. Chinese players like ByteDance (10%), Moonshot (9.5%), and Alibaba (9.5%) gain traction via cost-efficient releases and strong local evals like C-Eval, but trail global standards. Recent April developments, including Meta's Llama 3 launch and updated Arena snapshots, squeezed odds for underdogs amid benchmark volatility.
