Traders assign 91% implied probability to "Other" as the best AI model on October 5, reflecting consensus that none of the listed Claude variants will lead. This stems from expectations of competitive gains by other labs through recent large language model releases, benchmark improvements, or capability demonstrations that have outpaced Anthropic's visible updates. The low single-digit odds on specific Claude models highlight limited recent signals of leadership from that line amid a fast-moving field where product timelines often shift. With resolution only days away, any last-minute announcements, safety evaluations, or third-party benchmarks could introduce volatility, though current skin-in-the-game odds point to stable trader views on the broader competitive landscape.
