3 prediction markets price this story:

  • Will DeepSeek have the best AI model at the end of October 2026? — resolved “No” on 31 Oct 2026. The market resolves by checking the arena.ai Text Arena leaderboard at 12:00 PM ET on October 31, 2026. The outcome is Yes if DeepSeek owns the model with the highest rank; otherwise, it is No. Readers often mistake the news headline for the resolution source or ignore the requirement to exclude AutoEval models.
  • Deepseek — the market puts it at 4%, closing 1 Jan 2027. The market resolves to Yes if DeepSeek holds the number one spot in any widely recognized AI model ranking before January 1, 2027. Otherwise, it resolves to No. Readers often mistake the linked news story about a US ban as the deciding factor, but only the model's global ranking matters.
  • Will DeepSeek have the best AI model at the end of November 2026? — the market puts it at 0%, with $2k traded in the last 24 hours, closing 1 Dec 2026. The market resolves by checking the arena.ai Text Arena (Overall) leaderboard on November 30, 2026, at 12:00 PM ET. The outcome is Yes if DeepSeek owns the model with the highest rank at that time, and No otherwise. Readers often mistake the linked news story about Huawei chips as relevant to the resolution, but only the specific leaderboard data counts.

Odds are the market's probability that the outcome happens, updated every few minutes. They are information about what traders expect, not a forecast we make and not investment advice.
