Trader consensus favors Anthropic at 57.5% implied probability for the #2 spot on the LMSYS Chatbot Arena's Style Control On leaderboard by April's end, driven by Claude 3 Opus's sustained high Elo ratings just behind GPT-4-turbo variants in recent snapshots. Google's Gemini 1.5 Pro (45%) gains traction from its April long-context upgrades, while OpenAI (41%) contends amid GPT-4-turbo optimizations. Chinese challengers like ByteDance (39.5%), Moonshot (39%), and DeepSeek (38%) surged via efficient open-weight releases like DeepSeek-V2, pressuring leaderboards with cost-effective scaling. Fluid daily evals and pre-May GPT-4o hype underscore uncertainty, with no confirmed #2 until final April 30 data.
