Description

This event tracks Anthropic's weekly market share performance on OpenRouter for the week of September 28, 2026. It evaluates whether the company's share exceeds specific percentage thresholds, reflecting its competitive position in the AI model market during that period.

Kalshi

All markets in this event resolve based on Anthropic's text market share by model author for the week of September 28, 2026, as reported by OpenRouter at 10:00 AM ET on the Monday following the week in question. Values will be rounded to one decimal place. If Anthropic's market share is not separately identified in the source chart—or is grouped under a category like “Others”—all markets resolve to No. Each market has a distinct threshold (ranging from 2.2% to 3.1%), and resolution depends on whether Anthropic's reported share exceeds that specific level. Kalshi disclaims any official affiliation with OpenRouter, and all trademarks remain the property of their respective owners.

If analysts generally predict a certain outcome, but this market shows a different probability, it suggests a divergence in expectations about the future of Anthropic’s market share.

On Kalshi, this market is priced using a continuous double auction, meaning traders buy and sell contracts representing different possible outcomes for the Anthropic market share. The price of each contract reflects the market’s implied probability of that outcome occurring. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. As more traders participate and new information becomes available, the prices adjust to reflect the evolving consensus. This dynamic pricing mechanism allows for a real-time assessment of expectations surrounding Anthropic’s performance.

Several signals or events could significantly impact this market. Major announcements from Anthropic regarding new product launches, partnerships, or financial performance would likely cause price fluctuations.
