Anthropic is expected to release its next Claude Sonnet model to the public by July 31, 2026, marking another step in the company's ongoing advancements in artificial intelligence. The release would follow previous iterations like Claude Sonnet 4.5 and 4.6, which have garnered attention for their performance and potential applications. The expectation of a new Sonnet model by the end of July is strong, with traders putting the likelihood at 94%, reflecting confidence in Anthropic's consistent product pipeline.

Background

Anthropic has been a prominent player in the AI landscape, known for its Claude family of models. The Sonnet series, in particular, has seen regular updates, with Claude Sonnet 4.5 introduced approximately nine months ago and Claude Sonnet 4.6 following about four months ago. These models are designed for various applications, with some analyses suggesting they could significantly impact how AI agents function. The upcoming model is expected to be explicitly named 'Sonnet' by Anthropic, distinguishing it from other model families like Opus or Haiku. The market's odds have steadily risen since tracking began, indicating growing anticipation for an imminent release.
