Description

This event tracks the weekly usage performance of OpenAI's models within a specific AI platform ecosystem. It measures whether OpenAI achieves certain usage thresholds relative to all other model authors during a defined period. The outcome depends entirely on independent platform analytics for that week.

Kalshi

All markets in this event resolve based on OpenAI's measured text generation market share by model author on the OpenRouter platform for the week ending Monday, August 31, 2026, using data published at 10:00 AM ET on that Monday. Each market has a distinct threshold (ranging from above 16.5% to above 20.5%) which, if exceeded by OpenAI's share, results in a 'Yes' resolution for that specific market. If OpenAI's contribution is grouped under an aggregated 'Others' category rather than listed individually, all markets resolve to 'No'. Kalshi explicitly disclaims any formal association with the data provider or benchmark methodology, and all intellectual property rights remain with respective owners.

Frequently asked questions

This market resolves around Sep 14, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final share figure will be compared against the market’s defined categories, closing the market based on publicly available data sources rather than internal metrics.
