The venue's own resolution text, verbatim
If OpenAI scores above 18.4% on OpenRouter text market share by model author week of Oct 5, 2026, then the market resolves to Yes.

This event will resolve based on 10:00AM ET Monday updated market share values reported by OpenRouter, rounded to one decimal place, for the week of Oct 5, 2026.

If the named model author’s market share is not separately identified in the source chart, including if it is included in “Others,” all markets in the event will resolve to No.

What the sources establish

No evidence provides OpenRouter's official Monday 10:00AM ET market share report for the week of Oct 5, 2026, showing OpenAI's text market share by model author rounded to one decimal place. The existing sources discuss other metrics or general trends, not the exact resolution condition.

The evidence is not in the form this contract requires. The rules require OpenRouter's 10:00AM ET Monday updated market share values for the week of Oct 5, 2026, with OpenAI separately identified and the value rounded to one decimal place. None of the provided sources show such a report from OpenRouter. The sources discuss AI market share in general or business spending through OpenRouter, but not the specific form required.

The event may well have happened. This contract does not resolve on that alone.

The named authority has not established this. The sources below report the event; the contract resolves on what its named source says.

OpenRouter's published market share values for the week of Oct 5, 2026, updated at 10:00AM ET on Monday Oct 5, 2026, showing OpenAI's text market share by model author above 18.4% (i.e., at least 18.5% after rounding to one decimal place).
