Google's recent Gemini 4 Carbon and Hydrogen releases, now generally available with strong results on Arena leaderboards and agentic benchmarks, anchor the 76.5% implied probability that traders assign to the company holding the top model by year-end.

With roughly six weeks remaining, the market reflects skin-in-the-game assessment of Google's current trajectory versus potential late-year shifts from competitors.
