Meta's 61.5% implied probability for third place reflects its recent gains on arena.ai leaderboards with Style Control On, including a +2.8 point rise in early November amid releases like Muse Ember and Spark variants. These models deliver strong multimodal performance and efficiency at lower costs, helping Meta close the gap on OpenAI while Anthropic's score dipped 5.4 points after Claude Fable 5.2 launched. Google DeepMind holds the top spot overall, but Meta's momentum in style-adjusted human votes and open-weight contributions positions it as the clearest near-term riser before month-end resolution. Upcoming benchmark updates and any further Meta or competitor drops could still shift the final lab ordering.
