Description

This event tracks the weekly usage performance of a specific AI model provider during a defined period. The outcome depends on whether the provider's share of text generation requests surpasses various thresholds. Results are determined by independent data reporting from a third-party analytics platform.

Kalshi

The event resolves based on OpenRouter's publicly reported text market share data for model authors during the week of Oct 19, 2026, measured at 10:00 AM ET on the following Monday. All percentages are rounded to one decimal place. If Anthropic's market share is not individually listed—and is instead grouped under a collective "Others" category—every market within this event automatically resolves to No, regardless of the numerical threshold specified. The platform Kalshi explicitly disclaims any formal association with OpenRouter or the data source, and all related trademarks remain the property of their respective owners. Each market has a unique threshold (ranging from 3.7% to 6.1%); if Anthropic's reported share exceeds that specific threshold, the corresponding market resolves to Yes, otherwise to No.
