Trader sentiment overwhelmingly favors Anthropic at 70% implied probability for having the best AI model by end of April, driven by Claude 3 Opus maintaining the top spot on the LMSYS Chatbot Arena leaderboard through late April, with superior performance in reasoning and coding benchmarks. Google's Gemini 1.5 Pro release on April 9 propelled it to second place at 9%, thanks to its massive 1-million-token context window, but it fell short of overtaking Claude in overall Elo ratings. OpenAI lingers at 6.5% amid anticipation for GPT-4o, previewed post-deadline, while dark horses like Moonshot's Kimi (3.6%) and DeepSeek (3.4%) gain traction for cost-efficient long-context capabilities yet trail in comprehensive evaluations. Probabilities reflect benchmark stability absent major pre-May launches.
