Prediction markets put the probability at 8%: Will Google have the best AI model at the end of December 2026. Currently, markets see this as unlikely (8% YES). This category has seen the most dramatic shift in 2026.

What’s Happening

The question of whether Google will have the best AI model at the end of December 2026 hinges on a leaderboard that has shifted repeatedly this year. On Google's published evaluation set, Gemini 3.7 Flash leads comparable models on LVBench long-video understanding at 85.4%, ahead of 78.9% for GPT-5.6 Terra and 68.5% for Claude Sonnet 5, while scoring 84.5% on CharXiv chart reasoning without tools and 88.7% with search and code execution. The model is natively multimodal, processing text, images, video and speech as a core capability. [Intelligentliving, Jul 11]

Category leadership, however, does not equal a single frontier crown. Google's momentum built through late 2025, when Gemini 3 drew heavy buzz as a potential leader in the AI age, with analysts noting a competing model could reshape cloud economics for rivals such as Amazon, which has partnered with Anthropic. Google's edge is broadest in adjacent categories: Nano Banana Pro ranked the best overall AI image generator in mid-2026, and the Pixel 10 Pro shipped the smartest on-device AI software on the market. Whether that translates to a top overall frontier model by December 2026 is a separate benchmark contest. [Fool, Dec 14]

Looking ahead, whether Google will have the best AI model at the end of December depends on releases still in the pipeline. Analysts flag GLM-5.5, a credible Chinese open-weight alternative expected to ship in the second half of 2026, as a factor that could accelerate competition, though US export controls on compute and safety concerns may slow the top end. Multiple frontier labs — OpenAI, Anthropic and Chinese entrants — remain in contention, keeping the probability that Google has the best AI model at the end of December narrow despite its strong multimodal position.
