Next Claude Opus Model: Humanity’s Last Exam Debut?
The evidence strongly supports Yes: the next Claude Opus model appears to have already debuted as Claude Opus 5.5, and the reported Humanity’s Last Exam scores are well above 45%. The remaining uncertainty is mostly about whether the market intends a different future Opus model, but under the stated rules the observed debut already clears the threshold comfortably.
Analysis
The central question is whether the next Claude Opus model debuts with an HLE score of at least 45%. The available information indicates that Claude Opus 5.5 is already the relevant qualifying debut and that its reported Humanity’s Last Exam performance is far above the cutoff, with multiple summaries placing it in the low 60s or even higher depending on tool use. That makes the basic threshold question overwhelmingly favorable to Yes, because the model does not merely clear 45%; it clears it by a wide margin.
The market structure also matters. The resolution rule keys off the next qualifying Opus model added to the Humanity’s Last Exam results, not the eventual existence of some later or hypothetical successor. If the first qualifying Opus release already appears with a score above 45%, the market should resolve Yes unless there is a dispute about whether that model is the one intended by the question. The recent context explicitly states that the next Opus model has already debuted and that its HLE results are above 45%, which strongly anchors the interpretation toward Yes.
There is a small residual risk in interpretation rather than substance. The main ambiguity would be if the market creator intended a later, unreleased Opus version beyond 5.5, or if the displayed score on the official site diverges from third-party summaries. Even then, the cited site-facing leaderboard figure is still above 45%, so the threshold itself remains satisfied. The current market price around 90.5% is already high, but I would still put the true probability higher because the available evidence is unusually direct and multiple independent summaries point in the same direction.
Arguments
For
- Arguments for Yes: The reported HLE score for Claude Opus 5.5 is comfortably above the 45% cutoff.
- Arguments for Yes: Multiple independent summaries repeat similarly strong results, reducing the chance that the benchmark was misread.
Against
- Arguments against Yes: If the question was meant to target a later Opus model, the current debut might not be the one the market creator had in mind.
- Arguments against Yes: Benchmark reporting differences between tool-enabled and tool-free modes could create confusion about which figure should count.
Key drivers
- Claude Opus 5.5 is already described as the next Opus model to debut on the HLE results page.
- Reported HLE scores for Opus 5.5 are well above 45%, including tool-free results above 60%.
Risk factors
- The market could have been intended to refer to a different future Opus release rather than Opus 5.5.
- A discrepancy between third-party summaries and the official displayed score could create a narrow resolution dispute.
Scenarios
Best case
The official HLE page clearly shows Claude Opus 5.5 as the qualifying debut, and the displayed score remains well above 45%, producing an unambiguous Yes resolution.
Most likely
Claude Opus 5.5 is treated as the relevant next Opus model and its displayed HLE accuracy stays above 45%, so the market resolves Yes without meaningful controversy.
Worst case
The market is interpreted as referring to a different future Opus model, or the official site does not show the same qualifying score in the required timeframe, leading to a No resolution or a delayed dispute.
