Chinese labs maintain a tight contest for third place on OpenRouter token share this week through aggressively priced flash models that drive developer volume, with StepFun’s newly launched Step 5 Preview surging into contention alongside established GLM variants from Z.ai and Xiaomi’s MiMo offerings. OpenAI’s GPT-6 Luna holds steady inference demand but trails the leaders in absolute growth, reflected in near-even market-implied odds near 50 percent across top contenders. Proprietary models from Anthropic, Google, and Meta trail further back, while open-weight cohorts now exceed 70 percent of platform usage. Final resolution hinges on daily token aggregation through October 25, where any late acceleration in a single lab’s high-volume models could shift the ranking.
This market will resolve to the AI lab with the third highest market share on OpenRouter for the week of October 19 to October 25, 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 19 to October 25, 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 19 to October 25, 2026 once the figures for the week of October 26, 2026 are first displayed. If the figures for the week of October 26, 2026 have not been displayed by 11:59 PM ET on October 30, 2026, this market will resolve according to the figures displayed for the week of October 19 to October 25, 2026 at that time. If no data is available for the week of October 19 to October 25, 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 3rd after applying this ranking.
