DeepSeek’s recent release of the V4.1 Flash 1017 model on October 17 has reinforced its lead in OpenRouter token volume, with the lab commanding 28.7% share in the latest snapshot covering 161T tokens. Traders assign it a 76.5% implied probability of finishing first for the week of October 19 because its low-cost, high-context architecture continues to attract agentic and high-volume developer workloads that favor price and speed over U.S. frontier models. Chinese labs overall benefit from aggressive pricing that captures the majority of routed usage, while OpenAI, Anthropic, and Google trail in aggregate tokens despite stronger per-token revenue. The market-implied odds reflect ongoing sensitivity to any new model drops or benchmark shifts that could alter routing patterns in the coming days.
This market will resolve to the AI lab with the 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.
