Anthropic's Claude is a widely-adopted large language model used across software development, research, and business applications. As of April 2026, the latest released version is Claude Opus 4.7, which represents the current state-of-the-art in Anthropic's model family. The prediction market for Claude 5's launch by May 31, 2026 is currently trading at 12% YES odds, suggesting the community views an imminent release as unlikely. Anthropic has not made any public announcements regarding Claude 5 or its expected availability. Historically, Anthropic's major model releases follow extensive safety and evaluation periods, with significant gaps between major version releases. The low odds reflect this pattern—with just 44 days remaining until the deadline, observers see limited probability of a Claude 5 release. Odds have remained stable and low throughout April, indicating consistent market sentiment. The market will resolve YES if Anthropic formally announces and releases Claude 5 to the public before May 31, 2026 at midnight UTC. Any delay past that timestamp results in a NO resolution.
