Highest Claude score on Humanity’s Last Exam in 2026?
The conditions, incentives and evidence that could shape the answer.Highest Claude score on Humanity’s Last Exam in 2026: the question behind the price
A result on a difficult academic benchmark is evidence about that test, not a direct measurement of every kind of useful intelligence. In the snapshot checked October 4, 2026 at 09:57 UTC, the focus outcome, 55%+, was quoted at 88.1%. [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 specified company’s highest qualifying HLE Accuracy on the official Humanity’s Last Exam site by December 31, 2026 at 11:59 p.m. ET. Calibration error is not accuracy. Source downtime waits for restoration or official alternative results; no available official result produces No. [2]
The practical implication for 55%+ 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 60%+, quoted at 46%, gives a 42.10-percentage-point spread against 55%+. 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 $145,057 in cumulative turnover across its life. The captured record contains 5 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
What would change the outlook?
Will the highest score achieved by an Anthropic Claude model on Humanity’s Last Exam in 2026 be 55% or higher?
Quoted market evidence: Oct 4, 2026, 09:57 UTC. The live market panel may show a newer observation.

The next signals to watch
The observed 88.1% quote is the captured market expectation for 55%+. Publicly known conditions alone do not establish that this price is too high or too low. [1]

The selected condition, 55%+, was priced at 88.1% when checked October 4, 2026 at 09:57 UTC. A result on a difficult academic benchmark is evidence about that test, not a direct measurement of every kind of useful intelligence. [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. 88.1% 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]
