DataSnack's read

Gemini's lead rests on a restricted model, and Anthropic has just shipped

The Arena rank sets the narrative for enterprise buyers. The model's case rests on Gemini 4 Carbon's Oct 28 lead, with a replay error of 2.2 points a day versus 7.0 for standing still, though Fable 5.2 is untested on Arena.}

How the model works

Gemini 4 Carbon took the top spot on Oct 28, so the market starts at 75% and mostly stays put. It follows the sister November market for Google, with a possible Claude Mythos 5.5 release as the main risk to the lead.

• About 0.3 in log-odds of each move in the other November market's chance for Google carries into this market's chance over the next week. DataSnack's estimate, not yet tested on data.
