In a dramatic shift in AI model prediction markets, Anthropic has surged to a 76% probability of finishing February as the top model, up from just 7% on February 5. This leap has displaced Google, which has seen its probability plummet from 90% to 14%. OpenAI holds a 6% probability. Notably, a trader known as ProfessionalPunter has capitalized on this volatility, achieving a total profit and loss of $184,000. As the second-largest YES holder on Anthropic, ProfessionalPunter entered the market at approximately 60¢ and has already accrued around $5,000 in unrealized gains from this swing. This rapid market response underscores the agility of prediction markets compared to traditional media outlets.
