Anthropic's official release of Claude Opus 4.7 today, April 16, solidifies trader consensus at 100% implied probability for "on or prior to April 16," as the large language model is now live on Claude.ai, the Anthropic API, Amazon Bedrock, and Google Vertex AI with key upgrades including over 3x higher vision resolution, a new "xhigh" effort level for complex tasks, 1M-token context window, and automatic cyber safeguards. Preceding reports from The Information and codebase leaks signaled an imminent drop this week, driving early positioning, while extensive safety evaluations met Anthropic's rigorous standards. Barring an unprecedented rollback due to undisclosed issues—highly unlikely given multi-platform deployment—resolution appears certain, underscoring prediction markets' efficiency in aggregating real-time AI deployment signals.
