OpenAI holds an 87% implied probability of claiming the #3 spot on OpenRouter for the week of September 21 because recent token-volume data place it behind only DeepSeek and Z.ai, with roughly 12–19% share amid strong routing of its GPT-5.6 Luna and Astra models. Chinese labs continue to dominate overall usage through cost-efficient open-weight releases, yet OpenAI’s developer adoption on the platform has stabilized after earlier declines, keeping it ahead of Tencent, Xiaomi, Google, and others. Traders appear to view the outcome as relatively settled unless a late-week surge from another provider alters the ranking before resolution.
