Next Claude Opus released by...?

The most important fact is that Anthropic’s next Opus-branded model appears to have already been publicly released, with Claude Opus 5 listed as launched on July 24, 2026. If that release is officially verified and publicly accessible, then the market condition has already been satisfied well before the August 31 deadline. In that case, this is not a close forecasting question so much as a question of whether the market’s wording is being interpreted correctly. The current market price of 8.2% for Yes looks far too low relative to that evidence, which suggests the market may be underreacting or that traders are uncertain about the exact resolution criteria.

The strongest argument for Yes is that the description explicitly says the market resolves Yes if Anthropic’s next Claude Opus model is made available to the general public by the date, and the context says Opus 5 is already active and supported. A publicly announced, generally accessible Opus release is exactly the kind of event the market is designed to capture. The fact that Opus 4.1 is now deprecated and Opus 5 has taken its place also supports the conclusion that a new Opus generation has already arrived. Unless there is a hidden discrepancy between the reported release date and Anthropic’s official documentation, the outcome should be Yes.

The main reason for caution is interpretive, not operational. If some participants believed the question meant a model released after Opus 5, or if the event was created before the current naming changed, there could be confusion about whether the “next” model is the one already released or a future follow-on. However, the event description is explicit that qualifying models include any officially named Opus variant and that the release only needs to be publicly accessible. That makes the threshold relatively straightforward, and the reported state of the product line suggests the condition has already been met rather than merely anticipated.
