Pronóstico: Next Claude Sonnet released by 2026?

Platform comparison

Market context

Anthropic has just launched Claude Sonnet 5 to the general public on 30 June 2026, meaning the prediction market titled "Next Claude Sonnet released by..." will almost certainly resolve to "Yes" before its settlement window closes in July 2026. This real-world release confirms the contract’s 99% crowd-implied probability is not merely speculative but grounded in a live event that has already occurred.

Historically, Anthropic’s Sonnet lineage has followed a tight cadence: Claude 3 Sonnet arrived in March 2024, Claude 3.5 Sonnet in June 2024, Claude 3.7 Sonnet in February 2025, Claude Sonnet 4 in May 2025, and Claude Sonnet 4.6 in February 2026[1][3]. The pattern shows roughly four-to-five-month intervals between major Sonnet updates, with the latest jump from 4.6 to 5.0 taking just four months. This rapid iteration, combined with the deprecation of the original Sonnet 4 on 15 June 2026, created immediate pressure for a successor[4].

Traders should monitor Anthropic’s official announcements for follow-on Sonnet variants (such as 5.1 or 5.5) and confirm general availability across all major platforms including the Claude API, AWS Bedrock, and Google Cloud[8]. While the core release is confirmed, conditional token settlements on Polymarket depend on USDC liquidity and Polygon network finality; any delay in platform-wide access could technically affect resolution timing. The key catalyst remains public accessibility: if Sonnet 5 is usable by any general user via the standard API or claude.ai interface, the market resolves in favour of "Yes".
