Traders assign nearly identical probabilities around 42-43% to several late-November dates for Google's next Gemini model (4.1 or higher) because competitive pressure in the large language model race favors a rapid release to match rivals' recent capability jumps. Ongoing internal benchmarks, safety testing, and infrastructure scaling create uncertainty about the exact day, while historical Gemini timelines show flexibility around developer feedback and regulatory reviews. Key swing factors include any last-minute performance gains or executive statements that could accelerate or slip the window, with the spread across November 21-28 reflecting aggregated trader views on these variables rather than a single confirmed trigger.
