Next Claude Opus Model: Humanity’s Last Exam Debut?
The conditions, incentives and evidence that could shape the answer.Next Claude Opus Model: Humanity’s Last Exam Debut: the question behind the price
The model’s first appearance on the official result site sets the observation clock. Public release, a separate score announcement and a result for another Claude family are different events. In the snapshot checked October 4, 2026 at 09:57 UTC, the focus outcome, 45%+, was quoted at 94.4%. [1]
HLE covers multiple academic disciplines. [3] Our interpretation is that tools, attempts, scoring conventions and model versions must be kept comparable. A headline score that uses a different setup may be interesting research while failing this contract’s test. A higher result also leaves practical questions about reproducibility and the types of mistakes a model still makes.
The evaluation setup is part of the result
Uses the highest qualifying newly added Opus model’s displayed HLE Accuracy at noon ET the following day. Same-day entries count; next-day additions do not. A removed, unreinstated entry does not qualify. Seven-day source absence or no qualifying entry by December 31, 2026 means No. [2]
The practical implication for 45%+ is to distinguish necessary conditions from supporting clues. A plausible explanation can help identify what to investigate, but the outcome still turns on evidence satisfying the specified test. Treat the score as a reproducible test claim; avoid turning one number into a universal verdict about intelligence.
What the other prices and the trading record reveal
The comparison with 50%+, quoted at 90.35%, gives a 4.05-percentage-point spread against 45%+. That is a difference in quoted expectations, not a measured performance margin. Before treating the outcomes as a complete probability distribution, check whether they are mutually exclusive and whether a None, Other or fallback outcome is included. [1]
This event recorded $106,882 in cumulative turnover across its life. The captured record contains 4 eligible open constituent contracts. Those are the scope of this snapshot, not a count of independent forecasters. [1]
The next evidence that would change the assessment
For this event, watch the benchmark publisher’s result and methodology; the exact company, model version and tool setting; the required score boundary and publication deadline. [2]
The next meaningful update is evidence about the required milestone or measurement. A changed quote by itself does not identify what happened or why. A qualifying public benchmark result with the required model and evaluation setup would support the score threshold. An unofficial result, a different tool configuration or a score outside the allowed observation period could fail to qualify.
WEIGH BOTH SIDES

An unofficial result, a different tool configuration or a score outside the allowed observation period could fail to qualify. [2]
The next signals to watch
The observed 94.4% quote is the captured market expectation for 45%+. Publicly known conditions alone do not establish that this price is too high or too low. [1]

A FEW GOOD QUESTIONS
What else should you know?
Next Claude Opus Model: Humanity’s Last Exam Debut?
The selected condition, 45%+, was priced at 94.4% when checked October 4, 2026 at 09:57 UTC. The model’s first appearance on the official result site sets the observation clock. Public release, a separate score announcement and a result for another Claude family are different events. [1]
What evidence would be decisive for this particular outcome?
The key observations are the benchmark publisher’s result and methodology; the exact company, model version and tool setting; the required score boundary and publication deadline. The full linked contract governs exceptions. [2]
Does this market price prove the event will happen?
No. 94.4% describes the quoted focus condition in a dated snapshot. It is not a verified forecast, an official result or evidence that all participants independently evaluated the same information. [1]
