What will Anthropic's share be by Oct 28, 2026?

Comparing prediction market odds to analyst forecasts reveals how collective intelligence differs from expert opinion. Currently, analysts are divided on the future trajectory of AI model usage, with some predicting continued dominance by OpenAI and others anticipating gains for Anthropic. This market provides a real-time assessment of these possibilities, reflecting the aggregated views of a diverse group of traders. Discrepancies between the two can highlight areas where the market perceives information differently than traditional analysis, or where traders have access to unique insights not yet reflected in public forecasts.
