Kalshi

All markets in this event resolve based on Google's text model market share reported by OpenRouter for the week of September 28, 2026. The resolution occurs at 10:00 AM ET on the Monday following the week in question, using values rounded to one decimal place.

Several signals or events could significantly move this market. Major announcements from Google regarding new products, strategic partnerships, or financial performance would be key catalysts. Changes in the competitive landscape, such as significant moves by Apple, Microsoft, or Amazon, could also impact predictions. Broader economic trends, including shifts in consumer spending or advertising revenue, are also relevant. Unexpected regulatory decisions or antitrust investigations could introduce volatility. Any news that alters perceptions of Google’s future growth potential could influence trading activity in this market.
