Recent releases of advanced frontier models explain the overwhelming market consensus behind "Other." OpenAI launched GPT-6 Astra on September 3, quickly claiming top or near-top positions on multiple leaderboards for reasoning, coding, and agentic tasks, while Anthropic followed with Claude Fable 5.1 on September 1, often ranking first or second across intelligence and capability benchmarks. These updates outpace the listed Claude Opus variants in demonstrated performance and recency. Traders view the specific Opus options as unlikely to lead given the pace of iteration. A sudden, unannounced benchmark reversal favoring one of those exact models on September 7 remains a low-probability edge case that could still shift resolution.
