Anthropic holds a commanding 72.5% market-implied probability of fielding the leading AI model by end of June, driven by consistent benchmark gains and enterprise adoption of its latest Claude releases that have outpaced rivals in reasoning and safety evaluations. Traders view Google’s 20.5% share as reflecting strong multimodal progress from Gemini updates, yet still trailing in key capability benchmarks. OpenAI’s sharply lower 5.5% odds stem from slower iteration cycles after its prior model launches, while smaller shares for xAI, Meta, and others reflect limited recent public demonstrations or benchmark leadership. Key near-term catalysts include upcoming developer conferences and third-party evaluations that could shift the closely watched competitive landscape before the June resolution.
