Pronóstico: Next Claude Sonnet released by 2026?

Platform comparison

Market context

Anthropic’s next Claude Sonnet model is expected to launch for the general public before the settlement deadline of 31 July 2026, with the market currently pricing a 93% chance of a “Yes” outcome. This high probability reflects Anthropic’s consistent release cadence for Sonnet-tier models, which have typically arrived every four to six months since the Claude 3 family debuted in March 2024. For instance, Claude 3.5 Sonnet launched in June 2024, followed by Claude 3.7 Sonnet in February 2025, Claude Sonnet 4 in May 2025, and Claude Sonnet 4.6 in February 2026[1]. The pattern suggests a new Sonnet variant—potentially Sonnet 4.7 or Sonnet 5—could emerge in the second or third quarter of 2026, well before the deadline.

Traders should monitor Anthropic’s official announcements, particularly around major developer events or cloud platform updates, as these often precede model launches. A key catalyst is the recent deprecation of Claude Sonnet 4 and Opus 4 on 15 June 2026, which signals Anthropic is actively pushing users toward newer versions and may accelerate the release of a successor[4]. Additionally, the release of Claude Opus 4.8 on 28 May 2026[3] indicates ongoing development momentum, and community speculation on platforms like Reddit points to a potential Sonnet 5 launch in early 2026[2]. On-chain, the contract trades on Polymarket using USDC on the Polygon network, where conditional tokens determine settlement based on public availability confirmed via Anthropic’s API or official channels.
