This market will resolve to the AI lab with the second highest market share on OpenRouter for the week of October 5 to October 11, 2026. A lab's market share is the percentage displayed for that lab in the Market Share chart, set to Percentage, for the week of October 5 to October 11, 2026. The "stealth" and "others" groupings are not labs; if either occupies the relevant rank, it will be skipped and the next ranked lab will be used. This market will resolve according to the figures displayed for the week of October 5 to October 11, 2026 once the figures for the week of October 12, 2026 are first displayed. If the figures for the week of October 12, 2026 have not been displayed by 11:59 PM ET on October 16, 2026, this market will resolve according to the figures displayed for the week of October 5 to October 11, 2026 at that time. If no data is available for the week of October 5 to October 11, 2026 at that time, this market will resolve to "Other". The AI labs will be primarily ranked by the percentage displayed in the Market Share chart, set to Percentage. If two or more labs are tied on market share in percentage terms, the lab with the larger token count displayed in the Absolute view of the chart will be ranked higher. If a tie still remains, the lab whose listed name comes first alphabetically will be ranked higher. This market will resolve to the AI lab ranked 2nd after applying this ranking.

On Polymarket, this market is priced through a continuous auction mechanism, where traders buy and sell shares representing their belief in the probability of each outcome. The price of a share directly reflects the implied probability of that outcome occurring. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The market price adjusts dynamically based on supply and demand, meaning that as more traders bet on a particular AI lab gaining market share, the price of shares representing that outcome will increase, and vice versa. This creates a real-time assessment of the collective wisdom of the crowd regarding the OpenRouter AI landscape.
This market resolves around Oct 13, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The resolution will be based on determining which AI lab holds the second-highest market share on OpenRouter for the week of October 5. The data used to determine the market share will be sourced from OpenRouter’s official reporting, ensuring a transparent and verifiable outcome. This allows traders to confidently participate, knowing that the resolution process will be objective and based on publicly available information.
