The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Google has announced nothing. The market’s heaviest window is October 16–31, 2026, worth 42.5 points against 29 for the first half of October and 13 for all of September, so the pin takes the last day of that window. The day-by-day companion book leaves 88% on "no release by September 30".
The day-by-day version of the same question rules out September, pricing "no release by September 30" at 88% with no remaining day above 4%.[1]
Kalshi’s year-end ranking market is where a new Gemini Pro would show up, and it has Gemini third at 8.9% going into the release.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
