Which company's AI will first hit 1550 on Chatbot Arena in 2026?

Traders currently price "None in 2026" at 79% for "Which company's AI will first hit 1550 on Chatbot Arena in 2026?". Over the past 24 hours that probability moved up 1.0 points. Full distribution: None in 2026 79%, Anthropic 12%, Google 7%, OpenAI 4%. The market has traded $112K in total volume and resolves Dec 31, 2026. The dominant 79% implied probability for no model reaching 1550 Elo on the LMSYS Chatbot Arena by year-end 2026 reflects current frontier performance clustered around 1507–1512, with Anthropic’s Claude Opus 5 and Fable 5 variants holding the top spots. Steady but incremental gains over the past year—roughly 40–50 points since mid-2025—combined with only four-plus months remaining make a substantial leap unlikely absent a major capability jump. OpenAI’s GPT-5.6 series and Google’s Gemini 3.1 trail closely, while xAI’s Grok-4.6 sits just behind, underscoring tight competition yet limited headroom. Traders appear to weigh historical release cadence and benchmark trends against the risk of timeline slips or incremental rather than exponential advances in large language model capabilities.
