Google's Gemini 4 Argon Surges to 71% Odds of Top AI Model Spot by October, Challenging Anthropic's Dominance

Google has seized commanding odds in prediction markets to dethrone Anthropic as the company with the best-performing AI model by the end of October, with traders betting 71% probability on Google's latest Gemini 4 Argon against Anthropic's 28% odds, a dramatic reversal from earlier this year. The shift reflects Google's announcement of Gemini 4 Argon on September 30, 2026, its most powerful model to date, which the company says sets new records in real-world software engineering and ties for first place in cybersecurity benchmarking.
